Melt the caramel wafers on the stovetop, with a chocolate melting pot, or in a microwave safe bowl.
With a spoon or brush, paint the melted caramel into clean silicone molds. Make sure it is in an even layer and there are no thin, weak spots. Refrigerate until firm, about 15-20 minutes. You can also leave them at room temperature to firm up.
Carefully remove the dome halves from the molds. Use the molds as a stand while you assemble the cocoa bombs.
Into half of the domes, spoon in 3 tablespoons hot chocolate mix, mini marshmallows and any other fillings like sprinkles.
With the brush, paint melted caramel around the edge of one of the empty domes and, quickly, press it onto a filled half. Refrigerate until firm, about 15-20 minutes.
Decorate with some melted chocolate, sprinkles, edible glitter or candies.
Then remove from molds and place in cellophane bags or a gift box to give away or use!
Hot Chocolate with Hot Cocoa Bombs
First, warm some milk on the stove or in the microwave. Don’t boil it.
Place the hot chocolate bomb in a mug.
Then pour the hot milk over top. The chocolate shell will melt into the milk. Marshmallows and other fillings will float to the top.
