1 1/4 cups butter
2 1/4 cups all-purpose flour
1/2 cup powdered sugar
Filling:
4 eggs
2 cups sugar
6 T lemon juice (I used freshly squeezed)
4 T all-purpose flour
1 teaspoon baking powder
To make crust: Preheat oven to 350. Put butter in mixer bowl and beat until softened. Add flour and powdered sugar and mix on low speed until just combined. Spread dough evenly in a 9x13 inch pan. Bake for 10 minutes or until the corners are light golden brown. Remove from oven and pour filling on top of crust.
To make filling: In a small mixing bowl, mix together eggs, sugar, lemon juice, flour, and baking powder with a wire whisk or on low speed of a mixer for just a few minutes. (It is important not to mix a lot of air into the filling.) Pour on top of partially baked crust and bake for 30-35 minutes. Allow to cool slightly and dust with powdered sugar. Cut into small bars. Makes 18-24.
