Directions

Mix flour, powdered sugar and butter (may have to use hands to thoroughly mix). Press into greased 9 x 13 pan, making ½ inch edge around all sides. Bake at 350 deg for 20 minutes. Combine slightly beaten eggs, sugar, lemon juice and baking powder. Pour over hot crust and return to oven for 20 - 25 minutes. When cool, sprinkle with powdered sugar and cut into squares.

I often halve the batch and use an 8 x 8 pan.
