1 cake mix, any brand any flavor
1 small box instant pudding; use the same flavor as the cake
12 ounces sour cream
3/4 cups oil
1 cup water
Spray inside of crockpot with nonstick cooking spray. Mix all ingredients together and pour in crock pot. Cook on low for about 6 hours. Turn crock pot 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 crock pot half of it stays in the crock.
