Store mini pumpkin spice cupcakes chilled for up to 5 days.
Notes
Why add flour? The amount of product in a box of cake mix these days seems to be shrinking regularly. When I first developed this recipe, cake mixes were a standard 16.25 ounce. Due to the "shrinkage" of cake mixes I add additional dry ingredients to accommodate. It adds volume and stabilizes the batter.
The pumpkin needed for this recipe is canned 100% pumpkin puree not pumpkin pie filling. You can find it on the baking aisle of most grocery stores year-round.
Substitutions: Instant vanilla pudding lends a beautiful flavor and texture to the pumpkin cupcakes. You could use instant cheesecake pudding mix instead.
Variations: You could add 1 cup of chopped walnuts or pecans to the cupcake batter. The nuts should be finely chopped, since these are mini cupcakes.
