Preheat oven to 350°
Prepare 2 9" loaf pans by spraying with cooking spray and lining with parchment paper
In the bowl of an electric mixer put the cake mix, pudding mix, oil, buttermilk (or powdered buttermilk), eggs, sour cream, and pumpkin. Mix until well combined.
Stir in chocolate chips
Divide batter between two loaf pans
Bake 1 hour or until pick inserted in center comes out clean
Remove from oven and let cool about 10 min in pan. These loaves look like they've fallen, but that's normal.
Once completely cooled, frost with Cream Cheese frosting.
