Best Ever Chocolate Cake

Made this cake from the houston chronicle for my daughter's 16th and it was a hit!!

Preheat oven to 350 , and spray a 10-inch bundt pan with cooking spray.

Combine cake mix and pudding in a mixer bowl.

Add sour cream , butter , eggs and vanilla.

Beat on low speed until blended , scraping bowl as you go.

Fold in chocolate chips.

Batter will be quite thick.

Pour into bundt pan and bake 1 hour.

Let cool in pan 10 minutes , then turn out onto rack and cool completely.

Top with powdered sugar if desired.
