Creating Caramel Apple Cheesecake Bars involves multiple layers but follows a simple process. Follow these steps to ensure your bars turn out perfectly:

1. Preheat Oven: Begin by preheating your oven to 325°F (160°C). Grease a 9×13-inch baking dish with cooking spray or line it with parchment paper for easier removal.

2. Make the Crust: In a large bowl, combine the graham cracker crumbs, melted butter, and sugar. Mix until the crumbs are well coated. Press this mixture evenly into the bottom of the prepared baking dish. Bake for 10 minutes, then remove from oven and let it cool.

3. Prepare the Cheesecake Filling: In a mixing bowl, combine the softened cream cheese, sugar, and vanilla extract. Beat with an electric mixer until smooth and creamy. Add eggs one at a time, mixing well after each addition.

4. Pour the Cheesecake Filling: Spread the cheesecake mixture over the cooled crust, ensuring an even layer.

5. Prepare the Apples: In another bowl, toss the diced apples with sugar, cinnamon, and lemon juice until evenly coated. Spoon the apple mixture over the cheesecake layer.

6. Bake the Bars: Place the dish back in the oven and bake for 40-50 minutes, or until the edges are set, and the center still has a slight jiggle.

7. Cool Down: Once done, remove the dish from the oven and allow it to cool at room temperature for about 30 minutes. Then, refrigerate for at least 2 hours to set completely.

8. Add the Caramel Sauce: Once chilled, drizzle the bars generously with caramel sauce just before slicing.

9. Slice and Serve: Using a sharp knife, slice into bars and serve.

These straightforward steps will guide you through preparing the wonderful Caramel Apple Cheesecake Bars.
