Here is the recipe for the cake.
Here is the recipe I last used for the frosting. (Special thanks to my friend's mom for the recipe.)
One 8oz. package cream cheese, softened (I used the 1/3 less fat)
1 cup powdered sugar
2 cups Cool Whip (I used the light but I think the fat free might be alright)
Whip the ingredients together and frost the cake. This will need to stay refrigerated.
