Prepare the Crust: Preheat your oven to 350°F (175°C). In a mixing bowl, combine the graham cracker crumbs and melted butter. Mix until the crumbs are evenly coated. Press this mixture firmly into the bottom of a 9-inch springform pan to form the crust. Bake for 8-10 minutes, then set aside to cool.
Make the Filling: In a large mixing bowl, beat the softened cream cheese with an electric mixer until smooth and creamy. Gradually add in the sugar, mixing until well blended.
Add Flavor: Mix in the vanilla extract and Nutella, continuing to blend until combined. Scrap down the sides of the bowl if necessary.
Incorporate Eggs: Add the eggs one at a time, mixing on low speed until just combined after each addition. Be careful not to overmix the batter as this could make it dense.
Blend in Heavy Cream: Finally, gently fold in the heavy cream to the mixture until everything is well incorporated.
Bake the Cheesecake: Pour the filling over the cooled crust in the springform pan. Bake in the preheated oven for 55-60 minutes, or until the edges are set but the center still has a slight jiggle.
Cool and Chill: Once baked, turn off the oven and crack the door slightly. Allow the cheesecake to cool in the oven for 1 hour. Then refrigerate for at least 4 hours or preferably overnight to firm up.
Garnish: Before serving, sprinkle the top of the cheesecake with chopped toasted hazelnuts and shaved chocolate for an added crunch and visual appeal.
Notes
For best results, refrigerate overnight to allow the cheesecake to firm up.
