1/2 c. butter, softened
1 pkg. yellow cake mix
1/2 c. flaked coconut (optional)
1 (20 oz.) can pie-sliced apples or 2 1/2 c. sliced, pared baking apples
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 cake mix (dry) until mixture is crumbly. Mix in coconut. Pat mixture lightly into ungreased 13x9x2 inch pan, building up slight edges. Bake 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. Makes 12-15 servings.
