Why You Must Make

  • Hot Chocolate Bombs are all the rage. Your kids will think you’re a rock star as they watch the hot milk melt the chocolate and release the cocoa mix and marshmallows into the cup!
  • These chocolate bombs are fun and festive. They are a fun hostess gift packaged in a cellophane bag with some colorful ribbon along with instructions.
  • They look complicated, but once you have the molds, you’ll see how simple the process is!!

Using extra chocolate to drizzle over each chocolate bomb gives an opportunity to jazz them up with sprinkles! I picked some Christmas sprinkles along with some jimmies for a holiday flair. For the holiday season, this fun way to enjoy hot chocolate helps make a day extra special.

How to Make

  1. Lay your molds on a flat surface. I used a small rimmed sheet pan.
  2. Gather the fillings: hot cocoa mix, mini marshmallows, plus any add-ins.
  3. Melt the chocolate melts and stir until smooth.
  4. Paint a thin layer of chocolate onto the inside of each well using the back of a spoon or a silicone brush. Let cool and repeat. The inside does not need to look perfect, just make sure the inside of each mold is coated thoroughly.
  5. Cool at room temperature, then pop out of the molds. If your kitchen is warm, you can refrigerate to set the chocolate.
  6. Fill half the chocolate spheres with a spoonful of hot cocoa mix, then top off with mini marshmallows.
  7. Heat the rims of half the molds, one at a time, by placing the flat side on a warmed plate until the edge starts to melt.
  8. Top a filled shell with a shell with one with a melted rim and hold until the melted chocolate cools and seals the bomb.
  9. Repeat until all spheres are used.
  10. Drizzle with leftover chocolate and add sprinkles before the drizzle hardens.

Expert Tips

  • Use Chocolate Melts instead of real Chocolate Bars. Real chocolate will need to be tempered so the surface doesn’t get a grayish-white haze after it cools. No one needs that extra step this busy time of year!
  • Don’t overheat the chocolate.
  • To melt your chocolate, microwave at short intervals, stopping to stir before adding more time. When there are just a few tiny, unmelted pieces of chocolate, allow the residual heat of the chocolate to finish the melting process. If the chocolate isn’t perfectly smooth, you may need to microwave it one last time.
  • Paint enough chocolate inside your spheres to make them sturdy. Make sure the whole surface is well covered.
  • Other recipes suggest using a candle warmer to melt the edges of the chocolate half spheres, but I found a small heated plate worked well.
  • I used a regular hot cocoa mix, but there are other varieties you can try like peppermint, white chocolate, and gingerbread.
  • Drizzle some of the leftover chocolate over the chocolate bombs after they cool. Add festive sprinkles before the drizzle hardens.

How to Use

  1. Heat your milk to a simmer.
  2. Either put your chocolate bomb in the cup and add milk or drop the bomb into a cup of hot milk.
  3. Once the chocolate softens and the cocoa mix and marshmallows are released, stir well until the chocolate dissolves.
  4. Top with whipped cream, more marshmallows, or even a drizzle of caramel sauce! This will get you through a cold afternoon or even another season of a pandemic.

For the bomb shells

  • Ghirardelli Dark Chocolate Melting Wafers, you will not need all of the 10-ounce bag
  • 6 scant tablespoons Hot Cocoa Mix (I used Ghirardelli hot cocoa mix)
  • 30-36 mini marshmallows
  • Sprinkles

To serve:

  • 4 ½ cups hot milk (about ¾ cup per serving)
  • Extra marshmallows, whipped cream


  1. Melt about ½-¾ of the bag of chocolate melts in a heatproof bowl according to the directions. I use the microwave.
  2. Use a spoon to coat the inside of each mold with a thin layer and chill until firm. Spoon on another thin layer and chill. Remove each chocolate semi-sphere from the mold.
  3. In half of the molds, place a scant tablespoon of cocoa mix, then top with some mini marshmallows.
  4. One by one, heat the edge of an unfilled chocolate semi-sphere by placing it on a warmed flat plate until it starts to melt. Match up the edges with a filled chocolate shell and hold until the chocolate cools and seals.
  5. Place any extra melted chocolate in a piping bag and drizzle on top of each bomb. Decorate with sprinkles if desired before the drizzle hardens.
  6. To serve, place a bomb in a teacup or similarly sized coffee cup.
  7. Heat your milk to a simmer and pour over the bomb. After it melts, stir well to combine.
  8. Garnish with whipped cream, marshmallows, sprinkles, etc. if desired.


My molds were about 2-inches in diameter. You can use any size of semi sphere silicone molds, but you'll need to adjust your ingredient amounts.

I warmed my plate by pouring hot water from my teapot onto the plate. After a minute, I poured off the water and dried the plate.
