I just tried out this recipe over the weekend and MAN is it good. It's the richest moist chocolate cake I've had in a long time. And it even stayed moist for several days afterward.
1 chocolate cake mix
2c sour cream
2 small boxes instant chocolate pudding
1 bag chocolate chips
¾ c. oil
Mix above ingredients together in a bowl. Spray a crockpot with cooking spray. Pour the mixture into the crockpot. Cook on low for 4 hours. Don't lift the lid until it's done! Can be served with French Vanilla ice cream
