Preheat oven to 350 degrees and spray a 10 inch spring form (cheesecake) pan with nonstick spray.
Layer the apple slices in the bottom of the pan until they come about ⅔ of the way up the pan.
Sprinkle 2 tablespoon Cinnamon Sugar over the apples
In a large mixing bowl beat together the eggs and sugar until light and fluffy.
Add in oil and vanilla and beat well. Fold in the flour.
Pour batter over the apples and tap the sizes of the pan. Let the pan set for about 10 minutes for the batter to seep down in between the apples.
Sprinkle top with ¼ cup Cinnamon Sugar and bake for 1 hour and 20 minutes.
Let cake cool completely before slicing. We enjoyed the slices warmed in the microwave with ice cream.
