2 cups all-purpose flour
3/4 cup powdered sugar, divided use
1 cup butter
1/4 cup all-purpose flour
2 cups granulated sugar
2/3 teaspoon baking powder
1/2 cup lemon juice
4 large eggs
Preheat oven to 350*F.
Mix flour and 1/2 cup powdered sugar together. Using a pastry blender or fork, mix in 1 cup butter until well-blended. Press the mixture into an ungreased 13 x 9-inch pan. Bake for 30 minutes, or until lightly browned.
Meanwhile, to prepare the frosting, beat together flour, sugar, baking powder, lemon juice, and eggs.
Pour this mixture over the hot, baked bars. Bake again for 25 minutes. While still hot, dust the top with 1/4 cup powdered sugar. Cool before cutting.
Makes 24 bars.
