This recipe is from Put a Lyd on It and it is completely awesome! The cake turns out so moist and it's actually quite healthy as chocolate cakes go - no eggs or oil, just a can of pumpkin and water. And it turns out! I think that's uber cool. Oh, and it actually doesn't taste pumpkiny if that's a worry.
No Guilt Chocolate Cake
1 box chocolate cake mix (I used Pillsbury's Devils Food Cake and it was great)
1, 15 oz can pumpkin
1 cup water
In the bowl of a mixer (or you could use a hand beater) combine ingredients and beat for 2 minutes. Spread batter into a non-stick sprayed 9x13 baking pan and bake at 350 degrees for 30 minutes. Cool completely and top with lite Cool Whip, whipped cream, a sprinkling of powdered sugar or nothing at all. Mmmm...
