I recently went out for dinner and we had this chocolate stout cake. It was dense, sweet, malty, moist, bitter (maybe slightly too bitter) – but mainly just a delicious piece of cake. Something worth baking at home, with a couple of little changes.
First thing’s first – it’s the beer that gives this cake depth of flavour by introducing some of its fruity and malty notes, so the beer is one of the most important ingredients to think about.
In Harold McGee’s book ‘On Food and Cooking’, the beer style chart lists stout as being mainly dark and bitter. Porter on the other hand has a bit of caramel sweetness to balance the bitterness from the dark roasted malt. It also has a bit more fizz, which might help to leaven the cake. I’ll tell you what – it works. I’ll never again bake a chocolate cake without it… and the whisky in the frosting? Well, it’s the icing on the, you know, cake.
