1 box of Duncan Hines (I think!) devil's food cake mix and 1 can of pure pumpkin makes this luscious pumpkin-chocolate cake. I piped Pillsbury chocolate fudge frosting on top (used a ziploc bag as a piping bag) and added sprinkles. I normally make my cakes from scratch but today I was in need and I wanted it fast. It was so good and so satisfying.
