  • 120 g milk chocolate (about 4 1/4 ounces)
  • 6 teaspoons of mini marshmallows
  • 6 teaspoons of hot chocolate mix
  • Decorations of choice e.g sprinkles, edible glitter
  • Extra 20g of white chocolate for decoration if desired (about 3/4 ounce)


  • Break up milk chocolate into small pieces and place into a microwave safe bowl. Place this bowl into a larger bowl, half filled with hot water to help keep the chocolate from hardening.
  • Heat for 30 seconds and stir. Keep heating at 20 second intervals stirring in between until chocolate is fully melted.
  • Either using a paintbrush or back of a small spoon, coat the 6 molds in a layer of the melted chocolate.
  • Pop molds flat in the freezer for 3 minutes or until set.
  • Coat the molds in another layer of the chocolate and this time focus on the sides of the molds to make them thicker. The bottom of the molds will be quite thick already as this is where most of the chocolate settled from the first coat. Again, pop flat into the freezer for 3 minutes until set.
  • Very gently, pry the molds away from the chocolate and carefully push the chocolate out. Be very careful touching the chocolate as it is easy for your warm fingers to begin melting it and leave smudge marks. Keep your fingers cold or use food gloves placed in the freezer for a few minutes if needed.
  • Heat a small microwave safe plate in the microwave for 45 seconds.
  • Place one of your half bombs on the warm plate for just a couple of seconds so it can melt the edge.
  • Swiftly, fill that same mold with 2 teaspoons of hot chocolate mix followed by 2 teaspoons of mini marshmallows.
  • Take another half bomb and as before, melt the edge on the warm plate.
  • These two halves are now ready to create your full bomb, just place both halves together and hold for a few seconds.
  • Repeat this process for the other 2 bombs.
  • Lastly, comes the real fun part, decoration!! Use any leftover melted milk chocolate or use a small amount of melted white chocolate instead if preferred. Place chocolate into a piping bag or just drizzle over the bombs with a spoon.
  • This chocolate will harden quickly so add on your sprinkles, glitter, etc. quite quickly as the melted chocolate acts as a glue to hold it all on.
  • When ready to drink, simply place into a mug of hot milk and watch the bomb erupt. Give it a good stir before drinking and enjoy!
