Chocolate Cake with Chocolate Buttercream Icing

A cake I baked for a friend's birthday. Happy Birthday, N. Hope you get what you wish for this year!

It is my first properly decorated cake, ie. crumb-coated, buttercreamed, piped decoration. Because I didn't do a great job the first time around, I prepared another recipe of the ganache and coated it all over. So it is totally chocolate and sugar laden. To people who ate it at Saturday night's dinner, sorry guys if I put you off chocolate for a long while :).
