1 yellow cake mix
1 small box of jell-o instant pistachio pudding
1/4 cup oil
1 1/4 cup water
Mix all ingredients in a mixing bowl and mix with electric mixer for 4 minutes. (I have no idea why you have to do it for 4 minutes, that's just what the recipe said. It seems to me to come out the same whether you mix it for that long or not.)
Pour into greased 13 x 9 x 2 pan. Bake at 350 deg F for 45 to 55 minutes.
