This was so good... very rich and chocolaty, and not too sweet.
Unfortunately, I need a taller cake dome, as half the top came off with it.
From Allison, who got it from Epicurious. The recipe is there, with detailed instructions; I don't have any notes to add, other than that the best smell in the world turns out to be a bottle and a half of beer with a pound of butter melting into it on the stove. Who knew?
Served with whipped cream and raspberry sauce, because I can't resist any excuse to eat raspberries.
