cooking spray (for greasing a Bundt pan)
1 (18.25 oz.) Butter Recipe Golden or yellow cake mix
1/4 c. unsweetened cocoa powder, sifted
1/2 c. granulated sugar
1 c. sour cream
1/2 c. vegetable oil
4 large eggs
1 (12 oz.) bag mini semi-sweet chocolate chips

Do not preheat oven. Spray one 12-cup Bundt pan with vegetable cooking spray.

In a large mixing bowl, combine the cake mix, cocoa, sugar, sour cream and oil and beat with an electric mixer on low speed just to blend. Add the eggs and blend well. Increase the speed to medium-high and beat for 4 minutes. Fold the chocolate chips into the batter with a spatula and stir gently until they are well distributed. Pour the batter into the prepared pan and set the oven to 325°F.

Bake until a cake tester inserted in the middle of the cake comes out clean, about 55 minutes. Let the cake cool in the pan for at least 1 hour before slicing.

Makes 18 to 20 slices. This was in Midwest City Porcelain.
