1/2 c. butter, softened
1 pkg. yellow cake mix
2 1/2 c. baking apples, sliced, pared
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 crumbly. Pat mixture lightly on ungreased oblong pan (13 x 9 x 2 inches), building up slight edges. Bake 10 minutes. Arrange apples 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 edges are light brown. (Do not over bake.) Serve warm. 12 to 15 servings.
