Wizard of Oz cake for my daughters 5th birthday, all buttecream with rainbow done in color flow, shoes were chocolate, emerald city was done in hard candy (i used water bottle ice cube trays made of silicone for the molds)....searched high and low for something tube shaped and found these...silicone is great because its stands up to very high temps. I had to have the emerald city transparent and glossy kind of like the real thing. Will be doing cupcakes to match soon!
