1 box banana cake mix
1 stick butter, softened
1 egg

Mix together and pat into a 9 x 13 inch pan (it will be very thick). Mix together: 1 (8 oz.) cream cheese, softened 2 eggs 1 tsp. vanilla

Place on top of cake mixture. Bake for about 50 minutes in 325 degree oven. Check to see if it's done by inserting a knife in the middle. If it comes out clean, it's done.

If you can't find a banana cake mix, you can substitute yellow cake mix and 1 cup ripe mashed bananas.)
