Firstly, Nutella is a chocolate & hazelnut spread and Piroulines are chocolate hazelnut rods wrapped in wafers! The cake underneath is a Nutella Cake which was in "How to be a Domestic Goddess". The indentation in the cake is filled with chocolate ganache and topped with toasted hazelnuts. Surrounding the cake are cracked off piroulines which are secured with a real ribbon and bow!
