Place the graham cracker crumbs in a large bowl and pour in the unsalted butter slowly while mixing.
Stir in the Nutella.
Place the graham cracker crumbs in the bottoms of the pan.
Using your fingers press down the crumbs and up around the edges, place in the freezer.
Using an electric mixer, beat the softened cream cheese and Nutella on medium-high speed until smooth.
Add the sour cream, powdered sugar, heavy cream, and mix for 1-2 minutes.
Fill each cheesecake slot with the filling, smooth out the tops, and refrigerate for a minimum of 4 hours.
Place Ferrero Rocher on top, if desired.
Serve with whipped cream and enjoy!
