    I've made this a few times now and it's always a hit, deliciously moist and chocolaty without being too heavy. My only comment is on the cooking time stated, the first time I made this I made it as muffins and they were cooked within 30 mins but as a cake I've needed to leave it in the oven for well over an hour. Could be my oven, either way it's worth the wait!  -  12 Jan 2013
