Caramel Apple Cheesecake Bars!

For the crust:
2 c. flour
1/2 c. brown sugar
1 c. butter

For the cheesecake filling:
3 (8 oz) pkg. cream cheese, softened
3/4 c. sugar
3 large eggs
1 T. vanilla extract

For the apple topping:
3 granny smith apples, peeled, cored, and chopped
2 T. sugar
1 t. cinnamon
 1/4 t. nutmeg

For the streusel topping:
1 c. brown sugar
1 c. flour
1/2 c. oats
1/2 c. butter, softened

For the caramel sauce:
1/2 c. sugar
1/4 c. heavy cream

To make the crust, combine the flour and brown sugar.  Cur in butter with a fork until mixture is crumbly.  Press into a 9 x 13 inch pan lined with foil.  Bake at 350 degrees for 15 minutes or until lightly browned.  In a mixing bowl, beat the cream cheese with 3/4 c. sugar at medium speed until smooth.  Add the eggs one at a time, and then the vanilla.  Pour over the warm crust.  In a separate bowl, stir together apples, sugar, cinnamon, and nutmeg.  Spoon evenly over the cheesecake layer.  Then combine the brown sugar, flour, oats, and butter with your fingers to make the streusel topping and sprinkle over the apples.  Bake 40 minutes or until the filling is set.  To make the caramel sauce, heat sugar in a thin layer in a large saucepan until amber brown and bubbling.  Remove from the heat and add the heavy cream.  Pour the caramel sauce over the top of the bars.
