So I stocked up on the necessary ingredients and today had the opportunity to make it. There are a few stages involved in the cakes construction - baking and blitzing the nuts, melting the chocolate, beating the eggs - but it was soon in the oven and filling the house with an amazing aroma. Sadly I didn't have any homemade Italian chocolate hazelnut spread to hand so Nutella was the next best thing and it was very satisfying to spread over the cooled and turned out cake. Just a few hazelnuts for decoration and it was ready to eat.
