In a medium mixing bowl, combine the graham cracker crumbs, melted unsalted butter, and 2 tablespoons of granulated sugar. Stir until evenly coated and press into the bottom of a 9-inch springform pan. Bake for 10 minutes and let cool completely.
In a large mixing bowl, beat the softened cream cheese on medium speed until fluffy. Gradually add in 1 cup of granulated sugar and blend until smooth and creamy.
Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract and sour cream until the batter is smooth.
Pour half of the cheesecake batter over the cooled crust, spreading it evenly.
Spoon half of the Nutella over the cheesecake batter and swirl gently with a knife or spatula. Pour the remaining cheesecake batter on top, followed by dollops of the remaining Nutella. Swirl again for a marbled effect.
Bake for 55-60 minutes until the center is set but slightly jiggly.
Turn off the oven and crack the door open. Let the cheesecake cool in the oven for about an hour.
Transfer to the refrigerator and chill for at least 4 hours or ideally overnight.
Remove the sides of the springform pan, slice into wedges, and enjoy!
Notes
For an elegant touch, serve each slice garnished with a dollop of whipped cream and a drizzle of extra Nutella. A sprinkle of chocolate shavings or fresh berries can also enhance the visual appeal!
