1 package Duncan Hines cake mix, 1 (4oz.) box instant pudding (regular or sugar-free), 4 large eggs, 1/3 cup oil, 1 cup water.
Note: Chocolate cake mix with Chocolate pudding / Vanilla cake mix with Vanilla pudding / French Vanilla cake mix with French Vanilla pudding (or any other of your favorite choice).
Beat together with mixer and pour (thick batter) into desired cake pan and bake 350 degrees for 45 minutes.
Special note: If you have a checkerboard cake pan set, this recipe works great for a layered cake. It is moist and close to a pound cake consistency which holds together great.
