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

Heat oven to 350°F. Cut butter into cake mix (dry) until crumbly. Mix in coconut. Pat mixture lightly into ungreased oblong pan, 13 x 9 x 2-inches, 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; drizzle over apples (topping will not completely cover apples).

Bake 25 minutes or until edges are light brown (do not overbake). Serve warm.
