I made two of these cakes on the weekend - one for Donat's birthday (happy birthday, Donat!), and the other for Bruno's parents to sell at the local jazz festival (every year they have a fundraiser stall selling home-made cakes).
The cake is an easy-peasy flourless choccy cake (hazelnuts rather than almonds), slathered in ganache (chocolate and cream melted and then beaten together) and adorned with scorched hazelnuts.
I tried to make this cake a few weeks ago but buggered up the ganache. This time all went fine thanks to the old 'bowl-over-a-pot-of-simmering-water' trick.
It was pretty delicious! Very rich, though, so only small slices needed for full chocolate overload.
