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. You may prefer to prepare this the other way round from me, and get the frosting underway before you make the cakes. Either way, read the recipe through before you start cooking (I shouldn't have to remind) to get the shape of things in your head, not least because the frosting is softer, stickier than you may be used to. While you're making it, don't panic. The mixture will seem very runny for ages once the chocolate has melted and you will think you have a liquid gleaming glaze, beautiful but unfit for purpose; leave it for about an hour, as stipulated, though, and it will be perfect and spreadable. It never quite dries to the touch, but this is, in part, what makes the cake so darkly luscious. Goo here is good.
