If you are on any social media platform, chances are good that you have heard of hot chocolate bombs. Or perhaps you have seen them in action, either in person and in a video. It’s so easy to understand the universal appeal of these sweet treats!

The basic premise of a hot chocolate bomb is that you drop a hollow chocolate ball that has been filled with hot cocoa mix and other candies into a mug. Next you pour some piping hot milk over the chocolate ball and as the heat melts the chocolate, the contents of that bomb spill out. Some of the most popular fillings for hot chocolate bombs (besides hot cocoa mix) include:  sprinkles (or jimmies), marshmallows, and peanut butter.

Not only are hot chocolate bombs a relatively simple treat to make at home, the ingredients aren’t super expensive and will make a decent amount of bombs.

  • Let the molds sit for about 5 minutes & re-spread any of the chocolate that sank to the bottom of the molds.
  • Allow the chocolate in the molds to set and harden completely (approximately 2-3 hours). This process can be sped up by placing the mold in the refrigerator for about 1 hour.
  • Once the chocolate has set, remove each chocolate piece from the mold and lay half of the pieces on your work surface to be filled.
  • Add a small amount of instant hot chocolate to half of the pieces (approx 1 TBSP each), along with some sprinkles and marshmallows.
