1 box white or yellow cake mix
2 eggs
1/2 c. oil
2 tbsp. water
6 oz. pkg. chocolate chips

Mix all together until the batter is smooth; it will be very thick. Add the package of chocolate chips. Stir into batter and spread into 11 x 18 inch ungreased pan. Bake at 350 degrees for 20 minutes. These may be iced with peanut butter icing, if desired.
