Hot cocoa bombs are here to stay because they're easy, fun, and delicious! Fill them with your favorite cocoa powder, mini marshmallows, crushed candy canes and whatever else your heart desires. Drop one in a mug and pour hot milk or water over the ball. The ball “explodes” with a scrumptious surprise from the inside. These molds are a lot more fun with festive designs to choose from. BPA-free silicone molds are also great for making solid chocolate, ice cubes and jello-shots. Each design makes 3 spheres.
