Lemon Bars are a classic treat that no one can resist! A buttery crust is layered with a rich, sweet-tart lemon filling, then dusted with powdered sugar.
Preheat oven to 350°F (175°C). Line a 9" x 13" x 2" baking pan with parchment paper, and lightly grease the paper.
Whisk together the flour and confectioners' sugar. Add the butter, and mix with a pastry blender or a fork. The mixture should be coarse and meal-like.
Transfer the mixture to the prepared pan, and press firmly and evenly into the bottom of the pan.
Bake 20-25 minutes, or until lightly browned.
To make the filling:
Whisk together the flour and baking powder in a small bowl. Set aside.
In a separate bowl, combine the eggs, sugar, and lemon juice. Add the flour mixture, and mix well.
Pour over the partially baked crust. Bake 25-30 minutes, or the edges are lightly browned and the center is just set.
Place the pan on a wire rack, and allow the bars to cool to room temperature. Dust with more confectioners' sugar and cut into bars.
