Tangy Lemon Bars
A buttery shortbread base supports a bright, tart lemon curd filling that bakes to a perfect wobble. Dusted with powdered sugar, these bars taste like sunshine.
Ingredients
- 1 1/2 cups all-purpose flour, divided
- 1/2 cup powdered sugar, plus more for dusting
- 1/4 teaspoon salt
- 3/4 cup (1 1/2 sticks) unsalted butter, cold and cubed
- 4 large eggs
- 1 1/2 cups granulated sugar
- 2 tablespoons lemon zest
- 2/3 cup fresh lemon juice (about 4-5 lemons)
- 1/4 cup all-purpose flour (for filling)
- 1/4 teaspoon baking powder
Instructions
- Heat the oven to 350F and line a 9x13-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
- Pulse 1 1/2 cups flour, powdered sugar, and salt in a food processor, then add the cold butter and pulse until the mixture resembles coarse crumbs that clump when pressed.
- Press the crumbs evenly into the bottom of the prepared pan, pressing firmly with the bottom of a measuring cup to form a compact layer.
- Bake the crust for 18 to 20 minutes, until the edges are light golden brown. Leave the oven on.
- While the crust bakes, whisk the eggs, granulated sugar, and lemon zest in a bowl until combined, then whisk in the lemon juice.
- Whisk the 1/4 cup flour and baking powder into the egg mixture until completely smooth with no lumps.
- Pour the lemon filling over the hot crust immediately after it comes out of the oven.
- Return the pan to the oven and bake for 20 to 25 minutes, until the filling is set around the edges and only jiggles slightly in the very center - it should not look liquid when the pan is nudged.
- Cool the bars completely in the pan on a wire rack, about 1 hour, then refrigerate at least 1 hour to firm up fully before cutting.
- Lift the bars out using the parchment overhang, dust generously with powdered sugar, and cut into 16 squares with a sharp knife wiped clean between cuts.
Why You'll Love This
- Perfectly balanced tart-sweet lemon flavor
- Buttery shortbread crust that stays crisp under the filling
- Easy to make ahead and cut clean once chilled
Pouring the lemon filling onto the hot crust helps it start setting immediately and prevents a soggy bottom layer.
Chilling fully before slicing is what gives bakery-style clean edges instead of a runny bar.
