1/2 c. butter, softened
1 pkg. yellow cake mix
1/2 c. flaked coconut
1 (20 oz.) can pie sliced apples, well drained
1/2 c. sugar
1 tsp. cinnamon
1 c. dairy sour cream
2 egg yolks or 1 egg

Heat oven to 350 degrees. Cut butter into dry cake mix until crumbly. Mix in coconut. Pat mixture lightly into ungreased oblong cake pan (13 x 9 x 2 inch), building up slight edges. Bake for 10 minutes. Arrange apple slices on warm crust. Mix sugar and cinnamon; sprinkle on apples. Blend sour cream and egg yolks; drizzle over apples (topping will not completely cover apples). Bake 25 minutes or until edges are light brown (do not overbake). Serve warm.
