1 package chocolate cake mix
1 pint of sour cream
1 package instant chocolate pudding (any size)
1 6oz. bag chocolate chips
3/4 cup of oil
4 eggs
1 cup of water

Spray crock pot with non-stick spray. Mix all ingredients. Cook on low for 6-8 hours. Try not to lift the lid. Serve with ice cream.

Can also use low fat cake mix and sour cream with fat-free pudding and it still turns out great. It is very rich so be sure to have ice cream in the house. A little goes a long way. Keeps in fridge for a while. Just heat and serve.
