Preheat your oven to 350F. Pour the cake mix, pumpkin, and chocolate chips into a bowl. Stir until combined, and there are no pockets of dry mix.
Place cupcake liners in a standard muffin pan. Using a spring-release scoop, dip the batter out and place it in the muffin liners. (Optional, but they look prettier - place a few chocolate chips on the muffin batter.)
Bake for 20 minutes or until a toothpick inserted in the center of the muffin comes out clean.
