This isn't a hard recipe. I get tons of compliments on it. I got it from my decorating teacher. I think it can also be found on some Duncan Hines boxes. :)
1 package of cake mix
1 package of instant pudding in a corresponding flavor
1/2 cup water
1/2 cup oil
1 cup sour cream
Beat exactly 2 minutes. If you beat it 5 seconds longer, it will fall! Take my word for it.
If I am doing a cake for an order, than I sift the cake mix and the pudding together so the batter isn't lumpy.
It is thicker than the regular batter, so it will take some additional baking time. Don't ask me how long, I just bake until it is done. :D
