Preheat your oven to 350F.

Prepare one 9x13-inch glass pan by greasing thoroughly with butter or baking spray,

or light-colored metal baking pan with foil,

(be sure to cover the sides, you are going to use this to lift the bars).

In a mixing bowl combine graham cracker crumbs, rolled oats, melted butter and brown sugar together.

Press inside the bottom of a 9x13-inch baking pan.

Bake for 5 minutes. Remove from oven to cool.

Meanwhile in the bowl of your electric mixer blend together cream cheese, brown sugar, white sugar, cinnamon, ginger, cornstarch and vanilla.

Once well combined, pour on top of your graham cracker/oat crust.

To start your apple layer, arrange the thinly sliced apple on top of the cream cheese mixture in a single layer.

Top with the Apple Crisp Topping. Bake at 350F for 40-50 minutes.

Once it's done cooking, cool for 15 minutes, then refrigerate overnight.

Cut into squares. Serve with caramel drizzled over the top of cheesecake bars.
