  • Oven


Double Chocolate Pumpkin Cake

  • 1 box devils food cake mix
  • 1 box instant chocolate pudding small box
  • 1/2 cup canola oil or vegetable oil
  • 1/2 cup buttermilk or milk
  • 4 large eggs
  • 1/2 cup sour cream
  • 15 oz canned pumpkin reserving 2 tbsp for buttercream
  • 2 cups semi-sweet chocolate chips

Pumpkin Spice Buttercream

  • 2 sticks unsalted butter softened
  • 2 tbsp reserved pumpkin
  • 1/4 tsp ground cinnamon
  • 4-5 cups powdered sugar
  • 2-4 tbsp milk


Double Chocolate Pumpkin Cake

  • Preheat oven to 350 degrees F. and spray two 9x5 inch bread pans with non-stick cooking spray.
  • In a stand or electric mixer, place cake mix, pudding mix, oil, buttermilk, eggs, sour cream and can of pumpkin, and chocolate chips--mix all ingredients until well combined, about 1 to 2 minutes.
  • Divide cake batter evenly into prepared bread pans. Bake for 55-60 minutes or until cooked through.

Pumpkin Spice Frosting

  • Place butter, reserved 2 tablespoons pumpkin and cinnamon into stand or electric mixer. Mix on high until well combined. Slowly add the powdered sugar until thick and creamy. Slowly add the milk until buttercream is a nice consistency.
  • Frost over cooled cakes, slice and serve.


This recipe can be used to make 24 cupcakes as well. Bake at 350 for about 15-20 minutes, until baked through.
This recipe can also be used to make two 9 inch cakes for layered cakes. I'd start the bake time at 30 minutes at 350 and check often from there :)
