Creating these delectable Caramel Apple Cheesecake Bars is simple if you follow these steps:

1. Preheat the Oven: Preheat your oven to 325°F (163°C). Line an 8×8-inch baking pan with parchment paper for easy removal.
2. Make the Crust: In a bowl, combine graham cracker crumbs, melted butter, granulated sugar, and vanilla extract. Mix until well combined. Press the mixture evenly into the bottom of the prepared baking pan.
3. Bake the Crust: Bake the crust in the preheated oven for 10 minutes. Remove and let cool slightly.
4. Prepare the Filling: In a large mixing bowl, beat the softened cream cheese until smooth. Gradually add the granulated sugar, mixing until creamy.
5. Add Eggs and Sour Cream: Add eggs one at a time, incorporating well after each addition. Mix in the vanilla extract and sour cream until smooth.
6. Pour the Filling: Pour the cheesecake filling over the cooled crust, smoothing it out evenly with a spatula.
7. Prepare the Apples: In a separate bowl, toss the diced apples with lemon juice, brown sugar, and cinnamon until well coated.
8. Add Apples to Cheesecake: Evenly distribute the apple mixture over the cheesecake filling, pressing them slightly into the batter.
9. Bake the Bars: Bake in the oven for 30-35 minutes, or until the center is set and the edges are lightly golden.
10. Cool the Bars: Remove from the oven and allow to cool at room temperature for about 15-20 minutes. Then refrigerate for at least 2 hours to set.
11. Drizzle with Caramel: Once set, lift the bars out of the pan using the parchment paper. Drizzle with caramel sauce before cutting into squares.
