You may be thinking to yourself that a chocolate cake with chocolate frosting is a bit boring but I felt compelled to share it with you because this cake is truly something special.
The special ingredient is sour cream, which is present in both the cake and the chocolate ganache frosting. It really gives the cake much more depth of flavour.
It is taken from Nigella Lawson's "How to be a Domestic Goddess" and confirms her position as the queen of chocolate.
