Preheat oven to 350°F. Lightly mist a 12 cup Bundt pan with baking spray.
Place the cake mix, pudding mix, eggs, sour cream, warm water and oil in a large mixing bowl. Blend with an electric mixer at low for 1 minute. Then increase the speed to medium for 2-3 minutes. The batter will be thick.
Fold in the chocolate chips. Pour the batter into the prepared pan, smoothing it out with a spatula. Place the pan in the oven. Bake 45-50 minutes until it springs back when pressed lightly with your finger.
Remove the pan from the oven and allow the cake to cool for 20 minutes. Turn it out onto a plate and wait about 15 more minutes before icing with chocolate icing. You can add chocolate candies or sprinkles or just leave it plain
Enjoy thoroughly!
