Special equipment: 9-by-13-inch baking pan
Preheat the oven to 350 degrees F. Line an ungreased 9-by-13-inch baking pan with foil.
Mix the flour, butter and powdered sugar. Press the mixture in to the prepared pan building up 1-inch edges. Bake for 20 minutes.
Beat the sugar, lemon juice, lemon peel, baking powder, salt and eggs until light and fluffy, about 3 minutes. Pour over the baked crust. Bake until no indentation remains when touched, 25 minutes. Cool completely and sprinkle with powdered sugar. Cut into 4-inch squares and enjoy!
