With three chocolate layers, whipped Nutella filling and rich chocolate glaze, this really is THE ultimate chocolate cake.
• It is advisable to pipe the filling rather than spread it since the layers can be a bit fragile.
• The cake layers can be prepared a couple of days in advance. Once the cake is filled it is best consumed on the same day as it contains fresh cream.
• Replace the Nutella filling with whipped ganache, American buttercream or Italian meringue buttercream especially if you need to prepare the cake in advance for an event.
