Preheat oven to 350°F. Line a regular sized muffin tin with muffin liners or spray the tin with nonstick cooking spray.
In a large bowl using a hand mixer, mix the spice cake mix with the pumpkin puree until combined. (Can use a wooden spoon or spatula but takes a bit longer to get it well mixed).
Portion the batter into the muffin tins (muffin tins will be a little over ¾ full) and bake for 16-20 minutes . Or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
Remove from the oven and let cool in the pan for 5 minutes then transfer to a wire rack to cool completely.
Notes
Mix-ins
add 1 ½ cups of semi-sweet chocolate chips to the batter.
Raisins
Walnuts or pecans
You can use a different cake mix such as yellow cake mix or carrot cake (just don’t add the carrots). Because those cake mixes don’t have spices add a teaspoon or 2 of pumpkin pie spice to the batter.Add a glaze or cream cheese frosting to a more cupcake feel.Mini pumpkin muffins: Bake for 10 minutes at 350°F.
