Using a microwave-safe container (not glass), melt about 2/3 of the chocolate in the microwave. When the chocolate starts to melt, stir with a spatula occasionally until the chocolate is about 90% melted.
Add the remaining chocolate a little at a time, allowing it to melt completely before adding more chocolate. Stir with a spatula until all the chocolate is melted and not hot to the touch.
You can also melt chocolate using the double boiler method, where steam from the water melts the chocolate. For this method, you need to add chocolate to a large heatproof bowl (not glass) and place the bowl over the pot with water. Make sure the bowl is large enough to sit on the rim of the pot and not touch the water. Then, the process is the same: when the chocolate is almost melted, you need to add more chocolate and stir with a spatula.
When you have the chocolate ready, you can continue with the next step. Fill each of the cavities of the silicon mold with chocolate about halfway.
Using a spoon, spread the chocolate to the top of each cavity.
Using both hands, pick up the mold and tilt the mold back over the bowl of melted chocolate to shake out any excess.
Place the mold in the fridge to set for 10-15 minutes. Repeat with other molds.
Remove the molds from the fridge and carefully unmold half the spheres.
Heat a large pan until it gets warm, not too hot. After that, slightly melt the rim of a chocolate sphere in the warm pan. Do not melt all spheres, just half of them.
Place the melted spheres open side up and fill them with hot cocoa mix and mini marshmallows.
Melt the rim of the remaining half and seal the Hot Cocoa Bombs with another warmed half sphere.
Using a spoon, drizzle some of the chocolate back and forth over the bombs to decorate and top with sprinkles or marshmallows.
Let the bombs sit at room temperature for 20-30 minutes or until completely set.
How to Serve Hot Cocoa Bomb
Bring your favorite milk to a boil.
Place a Hot Cocoa Bomb into the mug and pour hot milk over it. You will see magic as the marshmallow will appear from the milk.
Let sit for a few seconds, and swirl with the spoon to combine. Enjoy!
