1mix together chocolate cake mix can of pumpkin and cup of water. Bake in a greased 9x12 baking pan. Bake a little longer than directed on package or until toothpick comes out clean. This cake is so very moist.
Combine peanut butter and cool whip...you may have to soften the peanut butter a little so that it has a consistency to combine with the cool whip. Spread this mixture on the cake and refrigerate for about 30 minutes. Rich and delectable without the calories.
