Calorific cheesecake from Nigella

Well it wouldn't be a cheesecake without the calories now would it? And if anyone knows how to do calories it is Nigella. She doesn't skimp on the butter and the chocolate.
Again this is so easy to make. It is a bit tricky to cut but if you put the knife in water before each slice it makes it a bit easier. It is not the most refined cheesecake and you will definitely find better recipes out there but it is yummy, especially as Nutella is one of my favourite things to spread on toast. It went down well as a dessert.

It's from her Nigellisma book.
