1 box yellow cake mix
2 sticks butter
1 box Devil's food cake mix
2 eggs

PART II:

2 lbs. powdered sugar
1 carton sour cream (8 oz.)
1 tsp. vanilla
1 (8 oz.) cream cheese
4 eggs

Use very large baking pan. (The aluminum disposable roasting pans are ideal). In a large mixing bowl beat 2 eggs with the yellow and chocolate cake mixes. Melt the butter and pour into bowl. Beat until well mixed. Batter will be thick. Spoon into a large pan to form a crust. In another bowl, put the softened cream cheese, the sour cream and the 4 eggs. Mix well. Add the 2 boxes of powdered sugar by small amounts until all has been mixed in. Add the vanilla and mix again. Pile onto crust in pan. Bake at 350 degrees for 1 hour and 15 minutes. Very moist and rich!
