Lemon Squares

Preheat oven to 350 degrees. Mix flour, butter, and powdered sugar. Press evenly into an ungreased 9×13 pan; make a little rim up the edges to hold in the filling. Bake 20 minutes.

Beat remaining ingredients (except for the powdered sugar) for about 3 minutes or until light and fluffy; pour over the baked crust, spreading evenly. Bake about 25 minutes or until no imprint remains when touched lightly in the center. Remove from oven and sprinkle with remaining powdered sugar. Cool, then cut into squares.
