1/2 c. butter or margarine
1/2 c. flaked coconut
1/2 c. sugar
1 tsp. cinnamon
1 (20 oz.) can pie sliced apples, drained or 6 medium apples, peeled and sliced
1 pkg. yellow cake mix
2 egg yolks
1 c. sour cream

Cut butter into dry cake mix until crumbly. Mix in coconut. Pat lightly into ungreased 9 x 13 pan. Bake 10 minutes at 350°. Arrange apples on warm crust.

Mix cinnamon and sugar; sprinkle on apples. Blend sour cream and egg yolks. Drizzle over apples. Bake at 350° for 25 minutes until edges are light brown.

I microwaved the apples on half power for 5 minutes beforehand.
