1 package yellow or white cake mix

1 quart vanilla ice cream, softened

1 cup blueberries

1 pint strawberries, hulled and thinly sliced vertically

Whipped cream or whipped topping

Prepare cake mix according to package directions. Pour into a waxed paper-lined and greased jelly roll or cake pan (about 16 x 12 inches); bake in a preheated 350 degree F oven 12 to 15 minutes or until toothpick inserted into center comes out clean. Let cool; invert onto large tray; peel off paper. Into same pan, spoon ice cream, smoothing and leveling off surface with a spatula to form an even layer. Freeze ice cream layer until firm. Dip pan in warm water for 10 seconds and unmold onto cake layer. To decorate cake, use blueberries for blue field, sliced strawberries for red stripes and pipe whipped cream for stars and to decorate sides of cake. Freeze. Remove from freezer 10 minutes before serving. (Makes 12 to 16 servings)
