Speaking of unusual recipes –

3 ounces instant chocolate pudding mix
4 eggs
1 cup water
2 cups sour cream
3/4 cup vegetable oil
3/4 cup semi-sweet chocolate chips
1/4 cup milk chocolate chips

Spray a 4 quart crock pot with non-stick cooking spray and set aside. In a large bowl, combine the cake mix and pudding mix. In a medium bowl, beat the eggs with the water, then add the sour cream and oil and beat until smooth. Add to the dry ingredients and beat well. Stir in the chocolate chips and walnuts. Pour into crock pot. Cover slow cooker and cook on low for 6-8 hours, until top springs back when touched very lightly with finger.
