Melt the candy melts according to the instructions on the package. I melted mine in the microwave on 50% power for 30 second intervals.
Add about about two teaspoons of melted chocolate to each mold. Use a spoon to spread the chocolate evenly around the bottom and sides of the mold.
Place the mold to chill in the refrigerator for about 5 to 10 minutes to allow the chocolate to harden.
Remove the mold from the refrigerator, add another thin layer of chocolate. Be sure there are no gaps or empty spaces. Place it back in the refrigerator for an additional 5 to 10 minutes.
Remove the mold from the refrigerator. Gently release the shells from the mold and place them on a piece of wax paper or a cookie sheet.
Fill the bottom half of each bomb with hot cocoa mix (2 tbsp.) and marshmallows.
Warm a plate or pan.
Take the top half of the sphere and place it on the plate until you see it starting to melt.
Quickly place it on top of the bottom half to seal your sphere.
Once they are sealed, place them back in the refrigerator for a few minutes to ensure they have hardened and set.
Finally, take them out and decorate them with melted drizzle, sprinkles, or any way you desire.
