From a friend, who got it from one of those church cookbooks that contain donated recipes.
1 yellow cake mix
1 stick oleo, melted (had to laugh, this is what they used to call margarine. Just use butter)
1 lb powdered sugar
1 (8-oz) pkg cream cheese
Mix together the cake mix, 2 eggs and oleo (butter), then press in the bottom of a 9 x 13-inch pan and around the edges. Then beat together the powdered sugar, 2 eggs and cream cheese. Pour in the middle of the dish. Bake at 350deg for 30 minutes, or until tooothpick comes out clean.
