It was my brother's birthday recently and being the good (baking addict) sister that I am, I always like to make him a special birthday cake. I was a bit unsure about how this would work out - as I've never made a cheesecake lacking side crusts - but I was beyond impressed with the result. If you're a chocolate lover, like the members of my family, you will love this cake. Don't be frightened by the overwhelming amount of 70% cocoa cooking chocolate, there is more than enough sugar in the recipe to counteract the bittersweetness of the chocolate.
