1/2 c. butter, softened
1 pkg. yellow cake mix
1/2 c. flaked coconut

Mix together and put into ungreased 13 x 9 x 2 inch pan, build up edges slightly. Bake 10 minutes at 350 degrees. Put 1 can of sliced apples on top of warm cake. Mix 1/2 cup sugar and 1 teaspoon cinnamon and pour over apples. Mix 8 ounces sour cream and 1 egg and drizzle over apples. This will not completely cover the apples. Bake 25 minutes or until edges are lightly brown in a 350 degree oven. Do not over bake.
