Make 6 heart-shaped chocolate shells or 12 chocolate half-sphere shells.
If using a silicone heart mold, fill with about 2 tablespoons of chocolate, and use a brush to paint the chocolate up the sides of the mold.
If using pure chocolate, chill the chocolate in the refrigerator until hardened, 5-10 minutes. If using compound chocolate (candy melts) place the mold in the freezer for 3-5 minutes until the chocolate hardens.
Paint a second coat of chocolate around the sides of the heart mold and chill just until hardened, 2-5 minutes.
If using a polycarbonate half-sphere mold fill all of the cavities in the mold with chocolate.
Invert the mold over a bowl of chocolate and allow some of the chocolate to drip out of the mold, leaving just a thin coating of chocolate in the mold.
Scrape off the excess chocolate.
Chill until hardened.
Fill all 6 of the heart-shaped chocolate shells or 6 of the chocolate half-spheres with mini marshmallows (or tiny dehydrated marshmallows) and 1-3 tablespoons of hot cocoa mix or chocolate ganache.
If you made chocolate hearts, pipe chocolate directly over top of the hot chocolate mix, then tap to remove air bubbles. Scrape off any excess chocolate, and chill until hardened.
If you made chocolate spheres, heat a skillet over low heat for 20-30 seconds. Melt the top edge of one of the empty chocolates and place it over top of a filled chocolate. Press gently to seal the two pieces together.
The quantities needed will depend on the size of your molds.
You will get 6 hot cocoa bombs that are 2 1/4 inches in diameter made and decorated using 18 ounces of chocolate. You'll need more chocolate for larger hot chocolate bombs.
You can fill your chocolate bombs with as little as 2 tablespoons of hot cocoa mix or chocolate ganache but I prefer 3-4 tablespoons for a richer hot chocolate drink.
Store your hot cocoa bombs at room temperature for up to 2 weeks if filled with chocolate ganache or up to 2 months if filled with hot cocoa mix.
To serve the hot chocolate bombs fill a coffee mug halfway with very hot milk.
Add the chocolate bomb then pour a little more hot milk over top.
Allow the chocolate to melt then stir into the milk to create a delicious cup of hot chocolate.
