The cake keeps well, refrigerated, for 3 days.
I panicked when I put it in the oven as it looked very runny. 15 mins Nowhere near long enough but maybe it's my oven. Left it in for more like 30/40 mins. It went down a treat with the family although I think next time I'll put more chocolate in and less sugar or maybe cocoa powder too. Topped it with the low fat chocolate icing on this site and served it warm. Scrummy. - 16 May 2015
