Which leads me to this super easy to mix chocolate cake; called a fudge cake by Good Food, I think it probably only deserves that name if you add the frosting. It is a dense, rich cake, but ever so slightly on the dry side (although I might have overbaked it slightly - I knew I should be checking it earlier when I could smell it baking, but was distracted by other things). Although there was nothing wrong with the cake, I think it would have been better with a frosting - I chose to serve it with just a dusting of cocoa and icing sugar.
I've called it an 'almost-all-in-one' cake as everything but some chopped plain chocolate was mixed together at the same time. You do need a measuring jug and a small bowl in which to dissolve the coffee, but there are no stages to mixing the batter. The chocolate is chopped in a food processor too, making this a really quick cake to prepare.
The coffee is there as a flavour intensifier - it can't be tasted in the finished cake. I was in two minds about chopping the chocolate - should I leave it as rubble or reduce it to grated filings? I left it as rubble, meaning little pockets of chocolate were detectable in the cake - I'm not sure if this was the intention, or whether a smooth texture was what was needed. I'll try it the other way next time, and decide which I prefer! This is definitely a cake to repeat, especially when something more rugged than a delicate sponge is needed.
