Preheat the oven to 325 F.
Mix the spice cake mix together with the pumpkin. Scoop into muffin liners. For a little variety, sprinkle some oats on top or cinnamon/sugar or break up some Halloween chocolate and put it on top.
Bake 18-20 minutes (until a toothpick comes out clean). You can also spread a little cream cheese frosting on top.
