Preheat oven to 350˚
Spray loaf pan (or skull pan). I used Pam Baking Spray.
In large mixing bowl, add cake mix, eggs, pumpkin puree (minus the reserved 2-3 TBSP if making the pumpkin whipped cream), and chocolate chips. Stir until well combined.
Gently stir in chocolate chips.
Spoon batter into prepared loaf pan, cupcake pan, or this skull pan. I filled a little over half way.
Bake at 350 degrees for 25 minutes (or more, up to 45-50 minutes) depending on the size pan you use. Check in 5 minute intervals until a toothpick inserted into the center comes out clean. This skull pan took approximately 45 minutes.
Serve with Pumpkin Whipped Cream
