There's only two ingredients. That's right, just the cake mix and the pumpkin (15 oz.). No oil, no eggs, no water, nothing else. The end result is an amazing, incredibly moist muffin/cupcake with a hint of pumpkin flavor. Bake at 350 degrees for 20-25 minutes. Notes: You can use Spice Cake mix. If you use the yellow cake mix, you might want to add a small amount of pumpkin pie spice.
