The second layer is 12 oz. of cream cheese softened to room temperature, mixed with 1 1/2 cups powdered sugar and 6 oz. coolwhip. Mix these ingredients well and spread on the first layer once it is totally cool.
The third layer is for us a layer of either lemon or chocolate pudding...2 boxes of instant pudding of whatever your flavor choice, mixed with 4 cups of milk. Pour over the cream cheese layer. I always let it set in the fridge a little while and then go back and spread a layer of coolwhip on like frosting. This has been both my daughter's and my choice of birthday dessert for at least 20 years! I make it every Christmas and Thanksgiving, and their birthdays. And maybe a time or two in between. I know it has other names but this is just what we call it. And there are other measurements given but this seems to fill the pan the best.
