Crockpot Cake

1 cake mix, any brand any flavor
1 small box instant pudding; use the same flavor as the cake
12 ounces sour cream
4 eggs
3/4 cups oil
1 cup water

Spray inside of crackpot with nonstick cooking spray. Mix all ingredients together and pour in crockpot. Cook on low for about 6 hours. Turn crockpot off and let sit for about 1 to 2 hours. Then you can flip it out onto a plate. If you do not let it cool long enough before taking it out of the crockpot half of it stays in the crock.
