Once completely cool if you are not decorating straightaway, wrap both cakes in foil. If you want a really deep chocolate fudge cake double the recipe which I do most times - looks fantastic.
If you're feeling adventurous pipe some small flowers or shells around the top edge of the cake and add a few Maltesers®. Add messages, basically anything you like. I've even made the top like rocky road by adding Maltesers®, small marshmallows and fudge pieces!
I made this cake for my son's birthday, as his best friend is allergic to eggs, and never gets to have a piece of birthday cake. I had already made it as a dummy run and it went down a storm. I added choc chips and it only needed 20 minutes in my oven as opposed to the stated 30. Loved it, well worth a try. - 28 Feb 2014
