Hello, I am useless at cooking; I can barely boil an egg. My wife has suffered a bad accident and will be hospitalised until next week. I would like to surprise her with a home made cake on her return, a chocolate type with that sort of chocolate topping, about enough for four people. Can someone direct me to or reply with an idiot's recipe and guide on how I make this without any electrical mixing equipment (I can get a whisk or any other simple kit). Also, if it's feasible to pipe it cheaply, that would be good too. It's an electric fan oven. Thanks, Paul.
