Forget the name, this cake is heavenly. The crumb is tender, the filling and frosting luscious. When I made it one Friday, I expected my children, resident food critics much in the mould of the Grim eater, to find it too dark, too rich, not sweet enough: you get the gist. Instead, I came down on Saturday morning to find nothing but an empty, chocolate-smeared cake stand and a trail of crumbs. And please read the Additional Information section at the end of the recipe before proceeding.
