Preheat your oven to 325°F (163°C). In a medium bowl, combine the graham cracker crumbs, melted butter, and 1/4 cup granulated sugar. Stir until the mixture looks like wet sand. Press it firmly into the bottom of the greased 8x8-inch baking pan, creating an even layer. Bake for about 10 minutes, then remove from the oven and set aside.
In a large bowl, use an electric mixer to beat the softened cream cheese until smooth and fluffy. Add 1 cup sugar and vanilla extract, mixing well. Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next.
In a small bowl, toss the diced apples with cinnamon until evenly coated. Gently fold the apples into the cream cheese batter, distributing them throughout the filling without overmixing.
Pour the cheesecake mixture over the warm crust in the baking pan, spreading it out evenly with a spatula. Bake for 40-45 minutes, or until the edges are set and the center jiggles slightly when you gently shake the pan.
Remove the bars from the oven and let them cool completely at room temperature. Once cooled, drizzle the caramel sauce evenly over the top. For an extra touch, you can use a toothpick or knife to gently swirl the caramel into the cheesecake layer.
Refrigerate the bars for at least 3 hours to allow the cheesecake to fully set. When ready, cut into squares and enjoy the perfect bite of creamy, fruity, and caramel goodness.
