Preheat oven to 350 degrees. Mix cake mix with the eggs,water and oil. Divide it into 4 thin layers and bake until firm, about 20 minutes. Remove from oven and let them cool.
For the filling: Beat cream cheese until fluffy, then slowly add the cool whip and confectioners sugar. Take the cooled layers and start putting the filling between the layers. The filling will be fairly thick between the layers. I have set the cake in the fridge for about an hour to let the layers set up before frosting the cake.
Frost the cake starting on the side of the cake to give the layers support and just continue frosting from there.This cake must be kept in the fridge until it is served.
