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
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.
