You can create unique cake decorations by making your own silicone moulds to offer truly custom cake designs. Moulds, impression mats and leaf presses are easy to make using silicone putty, available from suppliers. The putty has two components, which when kneaded together creates silicone that sets in 30 minutes. Silicone is durable, and you can use a variety of products in the moulds, such as fondant, gumpaste, cream cheese mints, isomalt, chocolate, etc. Silicone moulds work best to create flat or two-dimensional decorations, but small three-dimensional objects also can be created. You can use almost any item to imprint the silicone to create a mould: buttons from a bride’s dress, magnets, and jewelry or even sculpt your own pieces to use.
