Nigella Lawson's Torta alla Gianduia

Flourless chocolate cake. Are there three more beautiful words that are more perfectly suited for each other? I think not. Rich, dense, chocolatey.

As if that's not good enough, this cake is also baked chockfull of ground hazelnuts and Nutella and then frosted with a dark chocolate icing. I think this may be the holy grail of chocolate cake recipes.
