Ingredients

  • For the Shortbread Crust: 1 cup (125 g) all-purpose flour 1/4 cup (30 g) powdered sugar 1/4 teaspoon salt 1/2 cup (115 g) unsalted butter, cold and cubed
  • For the Lemon Filling: 1 cup (200 g) granulated sugar 2 large eggs 2 tablespoons (15 g) all-purpose flour 1/4 teaspoon baking powder 1/4 teaspoon salt 1/3 cup (80 ml) freshly squeezed lemon juice (about 2 lemons) 1 tablespoon finely grated lemon zest (about 1 lemon)
  • For Finishing: Powdered sugar, for dusting

Instructions

Preheat Oven:
Preheat the oven to 350°F (175°C). Line an 8-inch (20 cm) square baking pan with parchment paper, leaving an overhang for easy removal.
Prepare Crust Mixture:
In a medium bowl, combine flour, powdered sugar, and salt. Add the cold, cubed butter and cut it in with a pastry cutter or your fingers until the mixture resembles coarse crumbs.
Bake Crust:
Press the mixture firmly and evenly into the bottom of the prepared pan. Bake for 15 to 18 minutes, until lightly golden.
Make Lemon Filling:
Whisk together granulated sugar and eggs until smooth. Add flour, baking powder, salt, lemon juice, and lemon zest. Whisk until well combined.
Add Filling and Bake:
Pour the lemon filling over the hot crust as soon as it comes out of the oven. Return the pan to the oven and bake for an additional 18 to 20 minutes, or until the filling is set and just barely jiggles in the center.
Cool Bars:
Remove from the oven and let cool completely in the pan on a wire rack.
Serve:
Use the parchment overhang to lift out the bars. Dust with powdered sugar and cut into 16 triangles by first cutting into 8 squares then cutting each square diagonally.
