Preheat your oven to 350°F (175°C). Prepare a 9×13 inch baking dish by greasing it with butter or nonstick spray.

In a medium bowl, combine graham cracker crumbs, melted butter, and 1/4 cup of sugar. Mix until the mixture is moistened.

Firmly press the graham cracker mixture evenly across the bottom of the prepared dish to form a crust.

In a large bowl, beat the softened cream cheese with 1 cup of sugar and vanilla until the mixture is smooth and free of lumps. Scrape the bowl to incorporate all ingredients.

Add the eggs one at a time, mixing briefly after each addition until just combined.

Gently fold the diced apples into the cream cheese mixture using a spatula, ensuring even distribution of the fruit.

Pour the cream cheese filling over the crust and smooth the top with a spatula.

Drizzle caramel sauce over the surface, creating gentle swirls with a knife or skewer.

Sprinkle the cinnamon evenly over the top.

Bake for 30 to 35 minutes until edges are set and lightly golden; the center may wobble slightly but should not be liquid.

Allow the bars to cool to room temperature, then refrigerate for at least 2 hours before cutting into squares.
