Easiest Way to Make Edible Candy Shot Glasses - Use Candy Melts candy colors to make these Rainbow Candy Shot Glasses. Fill with layers of melted candy in alternating colors. Let it harden, and just “pop” them right out of the flexible silicone mold. Serve filled with liquor or even ice cream! This versatile silicone mold is oven-safe up to 500°F and freezer-safe. Make hard candy shot glasses, frozen shot glasses and jello shot glasses, too! Plus, it’s dishwasher-safe so cleanup is a cinch.
