Beat together the first 7 ingredients until smooth. Peel and thinly slice apples. Add sugar and cinnmaon to the apples. Put a thin layer of batter on the bottom of a prepared tube pan, then a layer of apples, more batter, more apples and top off with remaining batter. Bake at 350 F for 1 hour and 45 minutes. ( you may want to put a layer of alumium foil over the top during the last 15 minutes of baking to avoid too much browning.)
