Preheat your oven to 350°F (175°C). Line an 8x8 inch baking dish with parchment paper, allowing some overhang for easy removal later.
In a medium bowl, mix together the crushed graham crackers, melted butter, and 2 tablespoons sugar until well combined. Press this mixture firmly into the bottom of the prepared baking dish to form a crust. Bake for 8-10 minutes, or until lightly golden. Remove from the oven and let cool slightly.
In a large mixing bowl, beat the softened cream cheese and 1 cup granulated sugar together until creamy and smooth.
Add in the eggs one at a time, beating well after each addition, then stir in the vanilla extract. Scrape down the sides of the bowl as needed.
Gently fold in the chopped apples and cinnamon, ensuring they're evenly distributed throughout the cheesecake mixture.
Pour the cheesecake filling over the cooled crust and smooth the top. Drizzle half of the caramel sauce over the top and use a knife to swirl it into the batter for a marbled effect.
Bake in the preheated oven for 30-35 minutes, or until the center is set and only slightly jiggly. Allow the cheesecake bars to cool at room temperature.
Once cooled, refrigerate for at least 2 hours to set completely. When ready to serve, cut into squares and drizzle with additional caramel sauce, then sprinkle a pinch of sea salt on top for a delicious contrast.
Notes
For best results, refrigerate for at least 2 hours before serving.
