Well the cookie pan worked - although I am not sure this is the most exciting looking cake in the world, it was certainly a large cookie, don't you think? I resisted putting any decorations on (as it would have lost its cookie look) much to the disappointment of our nephews and nieces who are very fond of the odd sweet or two on a cake! The recipe on the box was in French and I just about managed to translate it. It seemed to have a HUGE amount of melted chocolate in (perhaps my translation was a bit wrong) and the result was rather similar in taste to a chocolate fondant pudding (yum yum)
