1 marble cake mix
4 eggs
1/2 c. warm water
1/2 c. oil
1 c. sour cream
1 pkg. vanilla instant pudding
8 oz. pkg. chocolate chips

Reserve marbling mixture from cake mix; blend and beat well all ingredients except chocolate chips. Set aside 1/2 cup batter and add it to the marbling packet. To white batter, fold in chocolate chips. Pour into greased tube or bundt pan; add chocolate mixture and cut through with a knife to marble. Bake at 350 degrees for 50 minutes. Rich and moist, needs no icing. Can be eaten with fingers so it is a good picnic cake.
