Preheat oven to 350^. Combine cinnamon and 5 tablespoons sugar and sprinkle over apples; set aside. Combine and beat remaining ingredients (except walnuts) in large bowl until smooth. Stir in walnuts. Pour half batter into a well greased 25 cm tube pan. Arrange half of apple mixture over it. Pour in the rest of batter and arrange the rest of the apples on top of the batter. Bake at 350^ for 1.5 hours. Allow cake to cool in an upright position. May be frozen for future use. NOTE: if apples look small then use 5 instead of 4! ----
