At Matt's request, here's the recipe for lemon squares:

½ cup powdered sugar
1 cup margarine or butter, softened

Filling:
4 eggs, slightly beaten
2 cups sugar
¼ cup flour
1 teaspoon baking powder
¼ cup lemon juice

Glaze:
1 cup powdered sugar
2 to 3 tablespoons lemon juice

Instructions:
Heat oven to 350˚F. In large bowl, combine 2 cups flour, ½ cup powdered sugar and margarine at low speed until crumbly. Press mixture evenly in bottom of ungreased 13X9-inch pan. Bake at 350˚F for 20 to 30 minutes or until light golden brown.

In large bowl, combine eggs, sugar, ¼ cup flour and baking powder; blend well. Stir in lemon juice. Pour mixture over warm crust. Return to oven and bake 25 to 30 minutes or until top is light golden brown. Cool completely.
