Begin by pouring the candy melts into a microwave safe bowl and heat for 30 seconds or until melts have fully melted.
Next spread the candy melts up the sides of the mold until the mold is completely covered with chocolate.
Then let the molds sit for about 5 minutes to begin to set at this point re-spread any of the candy melts that dripped to the bottom of the molds.
After that put the molds in the refrigerator for approximately 45 minutes to harden.
Once the chocolate has set, carefully pop the candy melt spheres from the mold.
Fill the bottom half of the spheres with the hot cocoa powder, sprinkles, and marshmallows.
To seal the hot cocoa bombs together place a glass plate in the microwave for one minute.
Remove the heated plate from the microwave immediately place the top of each chocolate sphere on the hot place to heat the edges.
Then place each heated sphere on the top of each filled sphere. Use the tip of your finger to smooth the melted candy around the seam.
Take the icing and draw lines back and forth on the top of your sphere, add sprinkles to continue to decorating your hot cocoa bomb.
