Classic Lemon Bars

Lemon bars are the dessert that proves tang beats sweet every time — a buttery shortbread crust crowned with a bright, silky lemon curd that is equal parts tart and sweet, finished with a snowfall of powdered sugar. They are the bake-sale staple that never makes it home, and the ratio of crust to curd is a matter of serious opinion. This version errs on the side of more curd, which is the only correct answer.

Why this recipe works: The crust is a simple shortbread — butter, flour, sugar, and a pinch of salt — pressed into the pan and blind-baked until golden. The filling is a classic lemon curd made with plenty of lemon juice and zest, eggs, and sugar, baked just until set. The result is a crisp, buttery base under a bright, wobbly-smooth layer that cuts cleanly into squares.

Key ingredients

• Butter: in both crust and curd — the flavor anchor.
• Fresh lemon juice and zest: bottled juice will not do; you need the zest for real lemon flavor.
• Eggs: the curd’s set.
• Powdered sugar: for the crust and the finishing snow.

Tips for perfect lemon bars

Blind-bake the crust until it is fully golden before adding the filling — a pale crust goes soggy under the curd. Whisk the filling gently so you do not incorporate too much air, and pour it over the warm crust. Bake at 350°F until the edges are set and the center barely jiggles, 20 to 25 minutes. Cool completely, then chill for at least 2 hours before dusting with powdered sugar and slicing — use a hot, wet knife for clean edges.

Variations and storage

Add a teaspoon of lavender or a spoonful of raspberry purée swirled into the curd, or swap the lemon for lime or Meyer lemon. Lemon bars keep 4 to 5 days in the fridge in an airtight container — if you dust them with sugar, wait until just before serving, or the sugar melts into the curd.
