Prepare using COOL WHIP LITE Whipped Topping.
For best results, use only fresh blueberries when preparing this cake. When baked, the berries and cake batter separate to form a layer of berries on the bottom with a lemon-scented layer of white cake on top.
To serve warm, reheat cake (in pan) in a 350ºF oven for 10 to 15 min. or just until warmed.
