Great chocolate cake! I wanted a moist, very low fat, chocolate cake recipe, so I omitted the pumpkin pie spice but otherwise followed the recipe. It's a wonderful, moist, not too sweet chocolate cake, and one I will make again and again. I did not glaze it, and mixed the chocolate chips into the batter before baking. Most reviewers said the chocolate overwhelmed the pumpkin, and I would agree - we couldn't even taste the pumpkin. But that's what we wanted.
