Instructions: 1. In a small bowl, mix cinnamon and 1/4 cup sugar.

2. Preheat oven to 375 degrees.

3. In a large bowl, with an electric mixer on high speed, beat butter and apple sauce until creamy; gradually add 1 cup sugar, continuing to beat until it is light and fluffy. Scrape the blow and beaters now and then with
a rubber spatula to incorporate all ingredients. Add egg and egg whites one
at a time, the vanilla, beating until well blended.

4. Sift flour together with baking powder, baking soda, and salt;. Using low speed, alternate adding the flour mixture and the sour cream into the butter and egg mixture. Mix well.

5. Spread one half of the batter in a well-greased 9 inch tube pan with removable bottom. Top with pared, cored, thinly sliced apple. Sprinkle with one half the cinnamon and sugar mixture.

6. Spread remaining batter over apples and cinnamon. Cover with remaining
cinnamon/sugar mixture.

7. Bake for 35 - 40 minutes or until a cake tester, inserted in the center,
comes out clean.

8. Remove the cake from the oven and let stand, in the pan, on a wire rack
for 30 minutes. With a metal spatula, loosen the cake all the way around the edges. Remove the sides of the pan. When completely cooled, remove from the tube pan onto a serving plate. Cut into wedges.
