  • Melt the chocolate using a double boiler or in the microwave. If using the microwave, heat for 15 seconds and stir, repeating as needed until chocolate is melted & smooth.
  • Spoon a small amount of chocolate into the mold. Using the paintbrush or the back of a spoon, spread the chocolate evenly around the mold, making sure to get all the way up to the top edges.
  • Allow chocolate to harden. Repeat layering on more chocolate until you have done 3-4 layers.
  • Refrigerate and allow chocolate to completely harden (about 30 minutes). Gently remove from the mold and place on a baking tray.
  • Fill half of the shells with 1 tablespoon of hot chocolate mix and mini marshmallows.
  • Heat a microwave safe plate until warm (approximately 30-60 seconds). Place an empty chocolate shell (flat side down) onto the plate to soften the edges. Quickly place the empty shell on top of the filled half. Use your finger to smooth out rough edges with melted chocolate.
  • To make cocoa: Place a hot chocolate bomb in a mug. Pour 1 cup of warm milk over the top to melt and reveal the treats within.


  • Be careful not to overheat the chocolate or it will seize.
  • Optional decorations: crushed candy canes, Andes mint pieces, sprinkles.
  • Store in an air tight container in a cool dry place, away from heat sources.
  • These can be decorated for any holiday by varying the colors & decorations.
  • Nutritional information will vary, based on ingredients & decorations used.
