A direct overhead shot of a full pan of lemon bars sliced into a perfect grid of squares and dusted with powdered sugar, with one square missing from the corner.

Ingredients

For the Crust:

  • 1 cup (2 sticks) unsalted butter, melted

  • ½ cup granulated sugar

  • 2 teaspoons pure vanilla extract

  • ½ teaspoon salt

  • 2 cups all-purpose flour

For the Lemon Filling:

  • 2 cups granulated sugar

  • 6 tablespoons all-purpose flour

  • 6 large eggs, room temperature

  • 1 cup fresh lemon juice (about 4-5 large lemons)

  • Powdered sugar, for dusting

Instructions

  • Prep: Preheat oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving enough overhang on the sides to lift the bars out later.

  • Make Crust: In a medium bowl, mix the melted butter, ½ cup sugar, vanilla, and salt. Add the 2 cups of flour and stir until a thick dough forms.

  • Bake Crust: Press the dough evenly into the bottom of the prepared pan. Bake for 18-20 minutes until the edges are lightly browned.

  • Dry Filling Ingredients: While the crust bakes, whisk the 2 cups of sugar and 6 tablespoons of flour together in a large bowl.

  • Wet Filling Ingredients: Whisk in the eggs until completely smooth. Then, whisk in the fresh lemon juice until fully combined.

  • Bake Together: Carefully pour the lemon filling over the warm baked crust. Return the pan to the oven and bake for 20-25 minutes, or until the center is set and no longer jiggles.

  • Cool & Chill: Remove from the oven and let cool completely at room temperature. Then, transfer to the refrigerator to chill for at least 2 hours to firm up.

  • Serve: Use the parchment paper overhang to lift the bars out of the pan. Slice into squares and dust generously with powdered sugar right before serving.
