It's my birthday on Sunday and I'll be off camping but since none of my friends have offered to make me a cake (sob! I'm usually the cake baker) I want to stop and pick up my own. Advice on the best rich sinful devilish deep dark chocolate cake with chocolate icing in San Francisco? I like 'em so moist that when you break it apart it makes luscious wet noises, and not so heaped with icing that it gives you diabetes. Also, I much prefer butter and eggs to artificial ingredients.
