The lemon bar base: one pan, eighteen bars

Every recipe below starts from the same base, so learn it once and the variations are easy. You need an 8 by 8 inch metal baking pan. Line it with parchment, leaving a 2 inch overhang on two sides so the whole slab lifts out for clean cutting. Glass pans work too, but drop the oven temperature by 25 degrees F and add 3 to 5 minutes to the crust bake, since glass heats more slowly. Heat the oven to 350 degrees F with a rack in the center. Make the crust first: whisk 1 cup all-purpose flour, 1/4 cup powdered sugar, and 1/8 teaspoon fine salt in a bowl. Cut in 1/2 cup (1 stick) cold unsalted butter, diced, using a pastry cutter or your fingertips until the mixture looks like coarse crumbs that hold together when squeezed. Press it firmly and evenly into the lined pan, all the way into the corners. Bake 18 to 20 minutes, until the edges are just turning golden. Do not let it brown deeply. While the crust bakes, whisk the filling: 2 large eggs plus 1 large egg yolk, 3/4 cup granulated sugar, 1/3 cup fresh lemon juice (2 to 3 lemons), 1 tablespoon finely grated lemon zest, 2 tablespoons all-purpose flour, and a pinch of salt. Whisk until completely smooth. Pour the filling over the HOT crust the moment it comes out of the oven. This is the step that keeps the crust crisp instead of soggy. Return the pan to the oven and bake 18 to 22 minutes, until the edges are set and the center still jiggles faintly when you nudge the pan. It should look set but not sloshing. Cool on a wire rack for 1 hour, then refrigerate at least 2 hours, or up to overnight. Cold bars cut cleanly; warm bars smear. Lift the slab out with the parchment, and cut with a long knife run under hot water and wiped dry between cuts. You will get 16 two-inch squares. Dust with powdered sugar just before serving, never before storing, because the sugar melts into the filling in the fridge. Storage for every recipe below: the filling is egg based, so refrigerate within 2 hours of baking (within 1 hour if the room is above 90 degrees F). Keep covered in the fridge up to 4 days. Freeze up to 2 months without the powdered sugar; thaw overnight in the refrigerator. Contains wheat, dairy, and eggs.

1. Lemon Bars With Orange Zest

A close view shows lemon bars sprinkled with fine orange zest, cut into neat squares inside a parchment-lined pan.

This is the base recipe, and it earns its place first. Orange zest folds into the lemon filling and rounds out the sharp citrus edge with something rounder and almost floral. The bars taste like pure sunshine without any harsh bite, which is exactly why this version photographs as the hero and bakes as a reliable first batch. You need (makes 16 bars): the full lemon bar base above, plus 1 tablespoon finely grated orange zest whisked into the filling, and 2 teaspoons extra orange zest for scattering over the top just before serving. Method: Bake the crust and mix the filling exactly as the base directs, whisking the orange zest in with the lemon zest. Pour over the hot crust and bake 18 to 22 minutes until the edges set and the center jiggles faintly. Cool 1 hour, chill at least 2 hours, cut with a hot dry knife, and finish with the reserved orange zest and a dusting of powdered sugar. Troubleshooting: If the bars taste flat, the zest was probably grated too shallowly. Use only the colored outer layer of the peel; the white pith underneath is bitter and will muddy the whole pan. Storage: Refrigerate covered up to 4 days; freeze up to 2 months. Add the fresh zest scatter only at serving time so it stays bright.

2. Lemon Bars With Coconut Topping

An overhead view shows nine lemon bar squares topped with toasted coconut flakes inside a parchment-lined pan.

Coconut and lemon are a natural pair, and this version leans into it without turning the bars into a candy bar. Sweetened shredded coconut goes on in the last minutes of baking, so it toasts to a pale gold right on top of the filling while staying chewy underneath. You need (makes 16 bars): the full lemon bar base above, plus 3/4 cup sweetened shredded coconut. Method: Bake the crust and mix the filling as the base directs. Pour the filling over the hot crust and bake 12 minutes. Pull the pan out, scatter the coconut evenly over the surface, and return to the oven for the final 6 to 10 minutes, until the filling is set with a faint jiggle and the coconut is lightly golden. Cool 1 hour, chill at least 2 hours, and cut with a hot dry knife. Dust with powdered sugar before serving. Troubleshooting: Coconut browns fast, so do not add it at the start of the bake. If your oven runs hot, check at 5 minutes and tent loosely with foil if the flakes are coloring too quickly. Storage: Refrigerate covered up to 4 days. The topping stays pleasantly chewy; it does not crisp, and that is the point.

3. Lemon Bars With Cinnamon Streusel

A close view shows lemon bars covered with golden cinnamon streusel crumble in a parchment-lined pan, with one square pulled forward to show the lemon layer and crust.

Think of this as the coffee cake version of a lemon bar. A buttery cinnamon streusel blankets the lemon layer, so each bite starts crumbly and spiced, then finishes bright and tart. It is the bar to bake when you want something that feels like fall but still tastes like spring. You need (makes 16 bars): the full lemon bar base above, plus a streusel of 1/2 cup all-purpose flour, 1/3 cup packed light brown sugar, 1 teaspoon ground cinnamon, 1/8 teaspoon fine salt, and 1/4 cup (1/2 stick) cold unsalted butter, diced. Method: Make the streusel before the bars go in: rub the flour, brown sugar, cinnamon, salt, and butter together until pea-sized crumbs form, then refrigerate. Bake the crust and mix the filling as the base directs. Pour the filling over the hot crust, crumble the streusel evenly over the surface, and bake 20 to 24 minutes, until the edges set, the center jiggles faintly, and the streusel is golden. Cool 1 hour, chill at least 2 hours, cut with a hot dry knife, and skip the powdered sugar here; the streusel is the finish. Troubleshooting: If the streusel sinks, the crumbs were too fine. Keep them chunky, about pea-sized, and scatter them over the filling rather than pressing them in. Storage: Refrigerate covered up to 4 days; freeze up to 2 months.

4. Lemon Bars With Raspberry Ripple

Lemon bars with a deep red raspberry ripple swirled through the lemon layer sit cut into squares in a parchment-lined pan.

A raspberry ripple turns a plain lemon bar into something that looks bakery made. Thin seedless raspberry jam gets swirled through the filling with a skewer before baking, marbling pink-red ribbons into the yellow custard. The flavor contrast is real too: tart lemon against jammy raspberry. You need (makes 16 bars): the full lemon bar base above, plus 1/4 cup seedless raspberry jam and 1 teaspoon water. Method: Bake the crust as the base directs. Stir the jam with the water until it is just pourable. Whisk the filling and pour it over the hot crust. Drop small spoonfuls of the thinned jam across the surface, then drag a skewer or toothpick through in lazy figure eights, two or three passes only. Over-swirling muddies the colors. Bake 18 to 22 minutes until set with a faint jiggle. Cool 1 hour, chill at least 2 hours, cut with a hot dry knife, and dust with powdered sugar. Troubleshooting: Use seedless jam. Whole seeds bake into hard little dots that get in the way of the silky texture. If you only have seedy jam, warm it and press it through a fine sieve first. Storage: Refrigerate covered up to 4 days. The ripple keeps its color well.

5. Lemon Bars With Vanilla Glaze

Lemon bars drizzled with white vanilla glaze in thin diagonal lines sit in a parchment-lined pan with two squares removed.

When you want lemon bars that look finished without the fuss of powdered sugar, a thin vanilla glaze is the answer. It sets into a delicate shell that cracks faintly when you bite, and the vanilla softens the lemon's tartness just enough if you usually find lemon bars too sharp. You need (makes 16 bars): the full lemon bar base above, plus a glaze of 1 cup powdered sugar, 1 tablespoon milk, and 1 teaspoon pure vanilla extract. Method: Bake, cool, chill, and cut the bars exactly as the base directs, but skip the powdered sugar. Whisk the glaze until it falls off the whisk in a thick ribbon; add more milk a few drops at a time if it is too stiff. Drizzle over the chilled, cut bars in thin lines with a fork or spoon. Let the glaze set 20 minutes at room temperature before serving or covering. Troubleshooting: If the glaze slides off, the bars were not cold enough. Chill them fully first, and keep the glaze on the thicker side rather than pourable. Storage: Refrigerate covered up to 4 days; the glaze will soften slightly after day two but still tastes fine. Freeze unglazed, then glaze after thawing.

6. Lemon Bars With Pecan Crust

Lemon bars dusted with powdered sugar fill a parchment-lined pan, and the square in front shows pecan pieces baked into its crust, with whole pecans scattered on the table beside the pan.

Grinding pecans into the shortbread base gives these bars a toasty, almost praline-like foundation under the bright lemon. It is a small change with a big payoff, and the crust holds together beautifully as long as the nuts are ground fine. You need (makes 16 bars): for the crust, 1/2 cup all-purpose flour plus 1/2 cup finely ground pecans (about 2 ounces), 1/4 cup powdered sugar, 1/8 teaspoon fine salt, and 1/2 cup (1 stick) cold unsalted butter, diced. For the filling, the standard base filling. Method: Pulse the pecans in a food processor until they look like coarse meal, not paste. Whisk with the flour, powdered sugar, and salt, then cut in the butter and press into the lined pan. Bake 20 to 22 minutes, until the edges are golden (nut crusts color a little faster, so watch the last minutes). Pour the filling over the hot crust and bake 18 to 22 minutes until set with a faint jiggle. Cool 1 hour, chill at least 2 hours, cut with a hot dry knife, and dust with powdered sugar. Troubleshooting: If the crust crumbles when cut, the pecans were ground too coarse. Aim for a texture like damp sand; large nut pieces break the crust's structure. Contains tree nuts. Storage: Refrigerate covered up to 4 days; freeze up to 2 months.

7. Lemon Bars With Hazelnut Pieces

An overhead view shows sixteen lemon bar squares topped with chopped hazelnuts in a parchment-lined pan, with whole hazelnuts scattered on the table around it.

Hazelnuts bring a deeper, almost chocolatey toastiness that plays surprisingly well with lemon. Chopped toasted hazelnuts get pressed into the crust and scattered over the top, so you get crunch in every layer. You need (makes 16 bars): the full lemon bar base above, plus 3/4 cup toasted hazelnuts, skins rubbed off, chopped. Use 1/2 cup pressed into the crust and 1/4 cup scattered over the filling. Method: Press the crust mixture into the pan, then press 1/2 cup of the chopped hazelnuts lightly into the surface. Bake 18 to 20 minutes until golden at the edges. Whisk the filling, pour over the hot crust, scatter the remaining 1/4 cup hazelnuts over the top, and bake 18 to 22 minutes until set with a faint jiggle. Cool 1 hour, chill at least 2 hours, cut with a hot dry knife, and dust with powdered sugar. Troubleshooting: Rub the hazelnut skins off in a kitchen towel after toasting; the papery skins taste bitter and will darken the crust. Contains tree nuts. Storage: Refrigerate covered up to 4 days. The nuts stay crunchy for about two days, then soften gently.

8. Lemon Bars With Sesame Crumble

Lemon bars topped with golden sesame crumble sit in a parchment-lined pan, with two squares pulled forward to show the lemon layer over the crust.

Sesame might sound unusual on a lemon bar, but toasted sesame has a nutty, almost savory depth that makes the lemon taste brighter by contrast. The crumble bakes up golden and crisp, and a pinch of flaky salt on top would not be out of place. You need (makes 16 bars): the full lemon bar base above, plus a crumble of 1/2 cup all-purpose flour, 1/3 cup granulated sugar, 3 tablespoons toasted sesame seeds, 1/8 teaspoon fine salt, and 1/4 cup (1/2 stick) cold unsalted butter, diced, and a pinch of flaky salt for the top (optional). Method: Rub the crumble ingredients together until pea-sized crumbs form; refrigerate while the crust bakes. Bake the crust and whisk the filling as the base directs. Pour the filling over the hot crust, scatter the sesame crumble over the top, and bake 20 to 24 minutes until set with a faint jiggle and the crumble is golden. Cool 1 hour, chill at least 2 hours, cut with a hot dry knife, and skip the powdered sugar. Troubleshooting: Use already-toasted sesame seeds. Raw seeds will not toast fully in the time the bars bake and can taste flat. Contains sesame. Storage: Refrigerate covered up to 4 days; freeze up to 2 months.

9. Lemon Bars With Maple Topping

Lemon bars coated in a glossy amber maple glaze sit cut into squares in a parchment-lined pan, with a small pitcher of maple syrup standing beside the pan.

Pure maple syrup folded into the filling gives these bars a warm, caramel undertone that makes them taste like autumn decided to visit a summer dessert. A final drizzle of warm maple at serving time turns them into something worth serving to guests. You need (makes 16 bars): the full lemon bar base, except replace 1/4 cup of the granulated sugar in the filling with 1/4 cup pure maple syrup, plus 1/4 cup warm pure maple syrup for drizzling at serving. Method: Bake the crust as the base directs. Whisk the filling with the maple syrup in place of 1/4 cup of the sugar; the filling will be slightly thinner, which is fine. Pour over the hot crust and bake 18 to 22 minutes until set with a faint jiggle. Cool 1 hour, chill at least 2 hours, cut with a hot dry knife, and skip the powdered sugar. Warm the extra maple syrup and drizzle over the bars just before serving. Troubleshooting: Use pure maple syrup, not pancake syrup. The imitation kind is mostly corn syrup and will make the filling gummy instead of silky. Storage: Refrigerate covered up to 4 days. Drizzle the extra maple only at serving time.

10. Lemon Bars With Brown-Butter Base

Five large lemon bar squares with deeply golden, toasty crust edges sit in a parchment-lined pan with one square removed, and whole and halved lemons rest beside the pan.

Browning the butter before it goes into the crust adds a nutty, toffee-like depth that makes these taste like the fancy version of the classic. It takes five extra minutes and a watchful eye, and it is worth every second. You need (makes 16 bars): the full lemon bar base above, except brown the 1/2 cup butter for the crust first. Method: Melt the butter in a light-colored saucepan over medium heat, swirling occasionally. It will foam, then the foam will subside and the milk solids will turn amber and smell nutty, about 5 minutes. Pour immediately into a heatproof bowl, including the browned bits, and cool 10 minutes until just warm. Whisk the flour, powdered sugar, and salt, then stir in the browned butter until crumbs form. Press into the lined pan and bake 18 to 20 minutes until the edges are golden. Finish with the standard filling, bake 18 to 22 minutes, cool 1 hour, chill at least 2 hours, cut with a hot dry knife, and dust with powdered sugar. Troubleshooting: Brown butter goes from perfect to burnt in under a minute. Pull it the moment it smells nutty and looks amber; the bits at the bottom should be golden brown, not black. Storage: Refrigerate covered up to 4 days; freeze up to 2 months.

11. Lemon Bars With Ginger Spice

Lemon bars with speckled, spice-flecked tops sit cut into squares in a parchment-lined pan, with chunks of candied ginger on the table beside the pan.

Ground ginger in the filling plus chewy bits of candied ginger on top give these bars a warm, tingling heat that builds slowly behind the lemon. They are the ones to bake when regular lemon bars feel too familiar. You need (makes 16 bars): the full lemon bar base above, plus 1 teaspoon ground ginger whisked into the filling, and 2 tablespoons finely minced candied ginger for scattering. Method: Bake the crust as the base directs. Whisk the ground ginger into the filling with the sugar and flour so it disperses evenly. Pour over the hot crust, scatter the candied ginger over the surface, and bake 18 to 22 minutes until set with a faint jiggle. Cool 1 hour, chill at least 2 hours, cut with a hot dry knife, and dust with powdered sugar. Troubleshooting: Mince the candied ginger finely. Large chunks sink and create wet pockets in the filling; small pieces stay suspended and distribute the heat evenly. Storage: Refrigerate covered up to 4 days. The ginger flavor deepens overnight, so these are excellent on day two.

12. Lemon Bars With Dried Cherries

An overhead view shows twelve lemon bar squares studded with dried cherries in a parchment-lined pan, with loose dried cherries scattered on the cloth around it.

Dried cherries bring a deep, almost wine-like tartness that stands up to lemon instead of hiding behind it. They soften slightly in the oven and turn jammy where they touch the hot filling, which means every bite has a little burst of something darker and richer. You need (makes 16 bars): the full lemon bar base above, plus 1/2 cup dried tart cherries, roughly chopped. Method: Bake the crust as the base directs. Chop the dried cherries so no piece is larger than a pea, then fold them into the whisked filling. Pour over the hot crust and bake 18 to 22 minutes until set with a faint jiggle. Cool 1 hour, chill at least 2 hours, cut with a hot dry knife, and dust with powdered sugar. Troubleshooting: Chop the cherries before folding them in. Whole dried cherries swell unevenly and can make the filling around them gummy, while chopped pieces distribute evenly and bake cleanly. Storage: Refrigerate covered up to 4 days. The cherries keep their chew for the full four days.

13. Lemon Bars With Cashew Crumble

Lemon bars topped with golden cashew crumble and whole cashew pieces sit in a parchment-lined pan, with two squares pulled forward to show the layers.

Cashews bake up buttery and sweet, and their mild flavor lets the lemon stay in charge. The crumble adds a toasty crunch on top while the crust below stays classic shortbread, so you get two textures framing one bright filling. You need (makes 16 bars): the full lemon bar base above, plus a crumble of 1/2 cup all-purpose flour, 1/3 cup granulated sugar, 1/3 cup finely chopped roasted cashews, 1/8 teaspoon fine salt, and 1/4 cup (1/2 stick) cold unsalted butter, diced. Method: Rub the crumble ingredients together until pea-sized crumbs form; refrigerate while the crust bakes. Bake the crust and whisk the filling as the base directs. Pour the filling over the hot crust, scatter the cashew crumble over the top, and bake 20 to 24 minutes until set with a faint jiggle and the crumble is golden. Cool 1 hour, chill at least 2 hours, cut with a hot dry knife, and skip the powdered sugar. Troubleshooting: Use roasted, not raw, cashews. Raw cashews will not fully roast in the bake time and can taste waxy. Contains tree nuts. Storage: Refrigerate covered up to 4 days; freeze up to 2 months.

14. Lemon Bars With Dark Chocolate Chunks

A close view shows lemon bars topped with large dark chocolate chunks in a parchment-lined pan, with the front squares showing the shortbread crust below the lemon layer.

Dark chocolate and lemon is a combination that surprises many bakers. The bitter edge of 60 to 70 percent chocolate cuts the lemon's sweetness and leaves something that tastes almost like a citrus truffle sitting on shortbread. Chill these well; the chocolate needs to be firm to slice cleanly. You need (makes 16 bars): the full lemon bar base above, plus 3 ounces dark chocolate (60 to 70 percent), chopped into small chunks. Method: Bake the crust as the base directs. Whisk the filling, fold in the chocolate chunks, and pour over the hot crust. Bake 18 to 22 minutes until set with a faint jiggle. The chocolate will look slightly melted on the surface, which is fine. Cool 1 hour, then chill a full 3 hours minimum so the chocolate firms up before cutting. Cut with a hot dry knife and dust with powdered sugar. Troubleshooting: Do not use chocolate chips. Their stabilizers keep them from melting into the filling properly, and you want small pockets of melted chocolate, not waxy dots. Storage: Refrigerate covered up to 4 days. These must stay cold until serving or the chocolate softens.

15. Lemon Bars With Almond Crumble

Lemon bars topped with crumble and sliced almonds sit in a parchment-lined pan with one square removed from the corner.

Sliced almonds in a crumble toast to a delicate crunch that shatters over the silky lemon layer. This is one of the most elegant-looking bars in the roundup, with a finish that looks bakery made. You need (makes 16 bars): the full lemon bar base above, plus a crumble of 1/2 cup all-purpose flour, 1/3 cup granulated sugar, 1/2 cup sliced almonds, 1/8 teaspoon fine salt, and 1/4 cup (1/2 stick) cold unsalted butter, diced. Method: Rub the crumble ingredients together gently, keeping the almond slices intact, until clumps form; refrigerate while the crust bakes. Bake the crust and whisk the filling as the base directs. Pour the filling over the hot crust, scatter the almond crumble over the top, and bake 20 to 24 minutes until set with a faint jiggle and the almonds are golden. Cool 1 hour, chill at least 2 hours, cut with a hot dry knife, and skip the powdered sugar. Troubleshooting: Watch the almonds closely in the last 5 minutes. Sliced almonds go from golden to burnt quickly, and dark almonds will taste bitter against the lemon. Contains tree nuts. Storage: Refrigerate covered up to 4 days; freeze up to 2 months.

16. Lemon Bars With Chocolate Drizzle

Lemon bars drizzled with thin dark chocolate lines and flecked with lemon zest sit cut into squares in a parchment-lined pan, with halved lemons blurred beside the pan.

If the dark chocolate chunks felt bold, this is their quieter sibling. A thin drizzle of melted chocolate over the chilled bars adds just enough cocoa to round out the lemon without competing with it, and the zigzag lines look beautiful in photos. You need (makes 16 bars): the full lemon bar base above, baked, chilled, and cut, plus 2 ounces dark chocolate (60 to 70 percent), melted. Method: Bake, cool, chill, and cut the bars exactly as the base directs, with a dusting of powdered sugar. Melt the chocolate gently in a heatproof bowl over simmering water or in short microwave bursts, stirring until smooth. Drizzle in thin lines over the chilled bars with a fork or a small spoon. Let the chocolate set 15 minutes at room temperature before serving or covering. Troubleshooting: Make sure the bars are fully cold before drizzling. Warm bars melt the chocolate on contact and it slides off instead of setting in clean lines. Storage: Refrigerate covered up to 4 days. The drizzle firms up in the fridge and snaps when you bite.

17. Lemon Bars With A Cream-Cheese Swirl

An overhead view shows nine lemon bar squares with a white cream-cheese swirl marbled through the yellow lemon layer in a parchment-lined pan.

A cream-cheese swirl turns lemon bars into something closer to a cheesecake bar, richer and less sharp. The marbled top is genuinely gorgeous, and the extra richness means these satisfy with a smaller piece, which is handy for a party platter. You need (makes 16 bars): the full lemon bar base above, plus a swirl of 4 ounces cream cheese at room temperature, 2 tablespoons granulated sugar, 1 large egg yolk, and 1/2 teaspoon vanilla extract. Method: Bake the crust as the base directs. Beat the cream cheese, sugar, egg yolk, and vanilla until completely smooth with no lumps. Whisk the lemon filling separately. Pour the lemon filling over the hot crust, then drop spoonfuls of the cream-cheese mixture across the surface and swirl with a skewer in figure eights, two or three passes. Bake 20 to 24 minutes until the edges set and the center jiggles only faintly (the extra richness needs the extra minutes). Cool 1 hour, chill at least 3 hours, cut with a hot dry knife, and dust with powdered sugar. Troubleshooting: The cream cheese must be truly at room temperature or it will leave lumps that never smooth out. If you forgot to take it out, cube it and let it sit 20 minutes, or beat it alone for a full 2 minutes before adding anything else. Storage: Refrigerate covered up to 4 days; these are best within 3 days. Contains dairy and eggs.

18. Lemon Bars With Toasted Walnuts

Lemon bars topped with chopped toasted walnut halves sit cut into squares in a parchment-lined pan, with loose walnut pieces scattered on the cloth in front.

Toasted walnuts give the final bar a rustic, bakery-case look and an earthy crunch that balances the lemon's brightness. Toast the walnuts yourself rather than buying pre-toasted; the difference in flavor is not subtle. You need (makes 16 bars): the full lemon bar base above, plus 3/4 cup walnut halves, toasted and chopped. Method: Toast the walnuts in a dry skillet over medium heat for 4 to 5 minutes, shaking often, until fragrant. Let cool, then chop. Bake the crust as the base directs. Whisk the filling, fold in 1/2 cup of the chopped walnuts, and pour over the hot crust. Scatter the remaining 1/4 cup over the top and bake 18 to 22 minutes until set with a faint jiggle. Cool 1 hour, chill at least 2 hours, cut with a hot dry knife, and dust with powdered sugar. Troubleshooting: Let the toasted walnuts cool before folding them in. Hot nuts can start cooking the egg in the filling on contact and leave streaks. Contains tree nuts. Storage: Refrigerate covered up to 4 days. The walnuts stay crunchy for about two days.

Lemon bar questions, answered

Why did my filling turn out runny?

It was underbaked. The center should jiggle faintly, like set gelatin, not slosh. Give it the full bake time, 18 to 22 minutes for most versions and 20 to 24 minutes for the streusel, crumble, and cream-cheese swirl versions, and remember the filling firms up as it chills. Cutting warm bars is the other common cause; the full 2-hour chill is not optional.

Can I use bottled lemon juice?

Fresh juice tastes noticeably better here because lemon is the whole point of the dessert. Bottled juice works in a pinch, but it has a flatter, slightly cooked flavor. If you use it, still zest a fresh lemon for the filling; the zest carries most of the bright aroma.

Why did my crust get soggy?

The filling went onto a cool crust. Pour it over the crust the moment it comes out of the oven, while the surface is hot. The heat sets the bottom of the filling instantly and seals the crust. Also, press the crust in firmly; a loosely packed crust absorbs more moisture.

Can I double this recipe?

Yes, use a 9 by 13 inch pan and double every ingredient exactly. Add 3 to 5 minutes to the filling bake and check for the faint jiggle. Do not stack two 8 by 8 pans and hope for the best; the bake times were built for one pan of this depth.

How do I get perfectly clean cuts?

Chill the slab at least 2 hours, lift it out with the parchment, and use a long knife run under hot water and wiped completely dry between every cut. A ruler helps too; 2-inch squares from an 8-inch pan is four cuts each way.

Can I make these ahead for a party?

Absolutely, and they are better for it. Bake them the day before, chill overnight, and cut and dust with powdered sugar the morning of the party. Most hold beautifully for 4 days refrigerated, and the flavor actually settles and improves by day two. The cream-cheese swirl is best within 3 days, and the hazelnut and walnut toppings stay crunchiest for about two days. Keep the 2-hour rule in mind when serving: refrigerate leftovers within 2 hours, or within 1 hour if the room is above 90 degrees F.

Bake one pan, then bake another

Eighteen versions, one base, and not a single complicated technique in the bunch. Start with the orange zest classic to learn the rhythm of the recipe, then chase whichever variation sounded best while you were reading. Lemon bars are forgiving, they pack well for a party when kept cool, and they are easy to share. Pick your pan, zest your lemons, and get baking. For more baking you can trust, the blueberry muffin recipes follow the same approach with real amounts and real timing, and the apple cinnamon overnight oats are a good make-ahead breakfast for the morning after a baking day.
