Begin by melting chocolate in a microwave-safe dish for around 1 minute, stir, stirring at 30-second intervals. If melted remove from the microwave. Using a silicone mold, fill each mold, with melted chocolate. Set in the refrigerator for 30 minutes to set up.
Carefully remove chocolate from molds and set aside. Gather hot cocoa mix, Nestle Buncha Crunch Candy, and set aside. Heat a small skillet on the stove, melt the edge of a chocolate half, and then fill with hot chocolate mix and a few pieces Nestle Buncha Crunch Candy.
Melt the edge of another chocolate half and then seal it to the other cocoa-filled chocolate half. Repeat.
To serve: Place a hot cocoa bomb in your mug, pour hot milk over the top, stir and top with whipped cream if desired.
