Step 1

In a food processor, combine flour, confectioners' sugar, and lemon and orange peel. Cut in butter until crumbly; process until mixture forms a ball.

Pat into a greased 9 x 13-inch baking pan. Bake at 350 degrees for 12 to 14 minutes or until set and the edges are lightly browned.

Meanwhile in a bowl, combine topping ingredients. Spread over filling. Bake 7 to 9 minutes longer or until topping is set. Cool on a wire rack. Refrigerate overnight. Cut into bars just before serving.
