A good friend gave me this recipe and it couldn't be easier. My kids also LOVE them!
1 box Spice Cake Mix
2 cups pumpkin puree
Mix together and bake at 425 degrees for 20 minutes.
My friend used the pumpkin pie mix but I had pumpkin puree in the freezer from last fall. I like the pumpkin puree better, it seemed to make a denser cake. Either way they are yummy and healthy. If you make 24, they come in at about 69 calories each and 12 muffins are about 138 calories each.
