✓ Preheat oven to 350°F (175°C) and line a 9×13‑inch pan with parchment paper.

✓ Combine graham cracker crumbs, melted butter, and 1/2 cup sugar in a bowl; stir until the mixture resembles wet sand.

✓ Press the crumb mixture firmly into the pan bottom, creating an even layer; bake for 8 minutes until lightly golden.

✓ Whisk cream cheese until smooth; add 1 cup sugar and beat until fluffy.

✓ Add eggs one at a time, mixing on low speed after each addition; do not overmix.

✓ Stir in vanilla extract and 1 cup caramel sauce until fully incorporated; the batter should be glossy.

✓ Pour the cheesecake batter over the pre‑baked crust, spreading evenly with a spatula.

✓ Place the pan on the middle rack; bake for 30 minutes or until edges are set and the center jiggles slightly.

✓ Do not open the oven door during the first 20 minutes; this ensures even rising.

✓ Remove from oven and let cool on a wire rack for 15 minutes; a gentle steam will escape.

✓ Drizzle an additional 1/2 cup caramel sauce over the warm cheesecake; watch the sauce ripple across the surface.

✓ Scatter chopped pecans over the caramel layer while still warm; they will adhere as the caramel sets.

✓ Allow the bars to cool completely at room temperature, then refrigerate for at least 2 hours; this firms the filling.

✓ Lift the parchment paper to release the slab; cut into twelve equal squares using a sharp knife.

✓ Wipe the knife blade between cuts to maintain clean edges; each bar should show a distinct crust, creamy center, and caramel‑glazed top.

✓ Arrange bars on a serving platter; optionally garnish with a few whole toasted pecans for visual contrast.

✓ Serve at room temperature for optimal texture; the crust stays crisp while the filling remains silky.
