This is my and my daughter Josephine’s favourite chocolate cake. It has a heavenly texture. It is like a chocolate soufflé – and it behaves like one, as it rises and falls. So don’t freak out as it drops in the middle, because it has no flour to hold it up. It keeps well for two days, as long as it isn’t put in the refrigerator; this will result in it becoming hard and unpalatable.
