Preheat your oven to 350°F (175°C). In a medium bowl, combine graham cracker crumbs, melted butter, and sugar until well mixed. Press this mixture firmly into the bottom of a greased 9x9 inch baking dish. Bake for 8-10 minutes until the crust is lightly golden brown. Once baked, remove from the oven and allow it to cool while you prepare the filling.

In a large mixing bowl, beat together the softened cream cheese and sugar using a hand mixer on medium speed until smooth and creamy, about 2 minutes. Gradually add the eggs one at a time, mixing well after each addition. Stir in vanilla extract and ground cinnamon, ensuring everything is fully combined.

Gently fold the diced apples into your cheesecake filling with a spatula. Pour this apple-rich mixture over the cooled graham cracker crust and drizzle caramel sauce over the top, creating gentle swirls with a knife or toothpick.

Place your dish in the preheated oven and bake for 30-35 minutes until the edges are set and the center is slightly jiggly. Once baked, let it cool completely at room temperature.

Once completely cool, cover the dish and refrigerate the cheesecake bars for at least 4 hours or overnight for best results. When ready, use a sharp knife to cut into squares, wiping the knife between cuts for clean edges.

Before serving, drizzle additional caramel sauce over each square. You can serve your Caramel Apple Cheesecake Bars chilled or at room temperature.
