Lydia's Guilt-free Chocolate Cake

1 box of Chocolate fudge cake mix (or any chocolate cake mix)
1 small can of pumpkin (you can't even taste it!)
1 cup of water

Put into a sprayed pan and bake at 350 degrees for 30 minutes. Cool completely and top with a low or nonfat cool whip or eat plain; it is so moist!
