Went to "Shockingly Delicious" blog after seeing Nutella hot chocolate (also easy and yummy). Found this recipe there and happened to have leftover pumpkin puree around that I needed to use up. Skeptical about how they'd come up with just box cake mix, pumpkin and some spice. They were delicious. Unusually moist texture. Kids LOVED them. Too easy not to be a staple recipe in my house.
