Begin with a box of yellow cake mix. Any kind will do except don't use the "pudding" kind.
Put the mix in a bowl and add a 15 oz. can of pumpkin puree. Not pumpkin pie mix.
Add 1 teaspoon of cinnamon, 1/2 teaspoon of nutmeg and 1/4 teaspoon of cloves. Mix together. Really mix. I found this hard to do because the batter gets really thick.
Line 12 muffin cups and fill them about 2/3 to 3/4 of the way with the batter.
Bake at 350 degrees for 25-30 minutes. Let cool and enjoy!
Warning: These contain a lot of fiber. If you have difficulty digesting fiber, this muffin is not for you. I found out the hard way, but Joe enjoyed the other 10. ;)
