I tried to do jelly in some silicone lego block moulds and they were a disaster! Thankfully the cake mould I borrowed to use turned out awesome! Getting fondant from the cake shop was a god send too. The colours were much more vibrant than I could make.

BG, I hate fondant too. For one thing, I have never used it on a cake. And for another, I don't like the taste of it. But I just put on extra butter cream underneath it as the crumb coat and peeled the fondant off. I also made the lego man double, and put some butter cream in the middle of them (like butter on a sandwich). The kids loved the fondant, lol!
