Has anyone tried the recipe with the cake mix and can of pumpkin puree? I saw that it was on Rachael Ray the other day and I wondered if it was good. It seems easy enough, combine devils food boxed cake mix with puree and bake in an 8" greased cake pan. Although I am a bit of a purist when it comes to diet baking recipes and I don't really believe in them, I am willing to give this one a try.
