Preheat your oven to 350°F (175°C). In a medium bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Stir until the mixture resembles wet sand.
Press this mixture firmly into the bottom of your 8x8-inch baking pan, creating an even layer. Bake for 8-10 minutes until the crust is set and lightly golden.
Remove from the oven and allow it to cool slightly while you prepare the filling.
Make the Cheesecake Filling
In a large mixing bowl, beat the softened cream cheese on medium speed until smooth and creamy, about 2-3 minutes.
Gradually add the powdered sugar and continue beating until fully incorporated.
Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
Finally, fold in the chocolate hazelnut spread gently until swirled but not completely blended, creating ribbons of flavor.
Assemble and Bake
Pour the cheesecake batter over the pre-baked crust and smooth the top with your spatula.
Sprinkle the chopped hazelnuts evenly over the surface.
Bake for 35-40 minutes, or until the edges are set and the center is slightly jiggly but not liquid.
Turn off the oven and leave the bars inside with the door slightly ajar for 10 minutes to prevent cracking.
Cool and Chill
Remove the bars from the oven and let them cool completely at room temperature.
Once cooled, place the pan in the refrigerator for at least 4 hours or overnight to allow the cheesecake to firm up perfectly.
When ready, cut into bars and serve chilled.
Equipment

Notes
Ensure cream cheese is fully softened to avoid lumps in the filling.
Do not overmix after adding eggs to prevent cracking during baking.
Gently warm chocolate hazelnut spread if it’s too thick for easier swirling.
Line the baking pan with parchment paper for easier removal and cleaner slices.
Chill bars overnight for best texture and flavor melding.
