Preheat oven to 350°F. In a bowl, mix together the pumpkin puree and spice cake mix until smooth and combined.

Line a muffin tin with liners or spray with non-stick spray. Fill each muffin cup about 2/3 full with batter.

Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.

Let cool slightly before serving. Enjoy as is, or top with cinnamon sugar or cream cheese icing for an extra touch!
