Step 1: Prepare the Crust

• Crush 1½ cups of graham crackers (about 10 sheets) into fine crumbs.
• Mix with 6 tablespoons of melted butter until the mixture resembles wet sand.
• Press firmly into the bottom of an 8×8-inch baking pan lined with parchment paper.
• Bake at 350°F (175°C) for 8–10 minutes, then let cool while preparing the filling.

Step 2: Make the Cheesecake Filling

• Beat 16 ounces (two 8-ounce packages) of softened cream cheese with ¾ cup granulated sugar until smooth.
• Add 2 large eggs, one at a time, mixing gently after each addition.
• Stir in 1 teaspoon of vanilla extract for enhanced flavor.

Step 3: Assemble the Bars

• Pour the cheesecake filling evenly over the cooled crust.
• Drop spoonfuls of Nutella (about ½ cup total) onto the surface.
• Use a knife or skewer to swirl the Nutella into the filling, creating a marbled design.

Step 4: Bake and Cool

• Bake at 350°F (175°C) for 25–30 minutes, or until the center is set but still slightly jiggly.
• Let the bars cool to room temperature, then chill in the refrigerator for at least 4 hours or overnight.

Step 5: Slice and Serve

• Lift the bars from the pan using the parchment paper.
• Cut into squares and enjoy!
