I love anything made with nuts, especially hazelnuts, and it's another easy cake to make. I decided to make it in a bundt tin.
Grease a bundt mould or cake tin and preheat oven 180C/gas4
In a bowl over simmering water, melt 150g butter and 150g dark chocolate. Take bowl off and add 4 egg yolks, 175g caster sugar, 80g ground hazelnuts, 100g plain flour, 50g dark chocolate chopped up and a pinch of salt.
Beat the 4 egg whites till stiff and fold into the mixture.
Spoon into the tin and bake for 50mins. Remove from tin and cool on a wire rack.
For the icing:
Chop 100g dark chocolate and melt it over water with 50g of butter. Pour it over the warm cake and leave to set.
One trick I learnt was to put the chocolate bar in a poly bag and tap it with a rolling pin to break it up. I usually end up with bits of chocolate everywhere!
The cake has a great chocolate flavour, and you can really taste the hazelnuts. The chunks of chocolate had just about kept their texture, but then melted in your mouth. I like the easy way you decorate it - no faffing with glacé icing or buttercream - just pour the chocolate over.
