1 yellow cake mix
1 box chocolate instant pudding
1 tsp. vanilla extract
1 c. sour cream
5 tbsp. rum
4 eggs
1/2 c. oil
1 c. chocolate pieces
1 c. walnuts

Combine all ingredients together (except chocolate pieces and nuts). Beat for 5 minutes, then add the rest, pour into greased tube pan and bake for 60 minutes at 350 degrees. Cool in pan for 30 minutes and serve. You may want to put a frosting on it or just sprinkle powdered sugar on top.
