Creamy Nutella Cheesecake with Chocolate Ganache and Toasted Hazelnuts

So my friend had asked me to help her make some cheesecakes for a Thanksgiving get together and we were standing around at Costco and started talking about Nutella. So the conversation quickly turned and then we decided to make a Nutella cheesecake as something different. I found this recipe online and it turned out to be a huge hit though it is very rich and should only be eaten in small pieces unless you have a sweet tooth.
