It's DS's fifth birthday on Sunday, and I have one of those silicone cake moulds, with about eight little car shapes on it. I also have a butterfly one for DD, but that will be for another time! How do you decorate these sometimes quite intricately shaped little cakes? It's way too big for a chocolate mould, so let's not go there. I was thinking rolled fondant, but that will be tricky, and I just had an idea now as I was typing, what about "poured" fondant? Or a thin royal icing? And then details could be painted on.

Thoughts? Most appreciated.

Ps, happy new year everyone!
