I did it with an electric one but don't think they had 'gone' properly, however I'm made the cake with half cocoa powder and half flour with orange essence, I divided them into cupcake cases instead, they have turned out ok, very springy and the cocoa I used if very overpowerig in taste, tastes like dark chocolate, will definitely
Make them again and try a plain sponge this time, thanks for the tip on egg whites x
