Pinner says: I make these pumpkin muffins every fall - they are SO amazing, and SO easy! Spice cake, pumpkin, and pumpkin pie spiceUm yum....... I may never eat anything else for breakfast again. Pumpkin Muffins - only 2 ingredients. That's right, just the cake mix and the pumpkin. No oil, no eggs, no water, nothing else. Bake at 350, this is a Weight Watchers treat, very low cal.
