Big Cakes: Penguin Cake

Originally designed as an alternative Christmas cake, there’s no reason not to make this at any time. The penguins need to be kept at room temperature and the cake should not be hours out of the refrigerator or it will become difficult to cut, so decorate shortly before you serve it. The penguins can be made a few weeks ahead and stored in a lidded cardboard box (not an airtight container or tin as they will sweat).
