Hot Cocoa Bombs

Content Protection by

I have been looking forward to making Hot Cocoa Bombs ever since they went mainstream this winter. I didn’t have a chance to make them for Christmas, so I thought… why not for Valentine’s Day? Hot Cocoa Bombs are little balls of chocolate that have a secret surprise inside. Remember the candy Wonder Balls? They remind me of those! I used to LOVE those as a kid and every trip to Blockbuster I would try to convince my mom to buy me one. Anyway, Hot Cocoa Bombs are a chocolate sphere that you place in a mug and pour hot milk, water or coffee over to melt the shell and release the hidden hot cocoa mix and marshmallows. You’ll need a few specialty items to make these, but it will be 100% worth it!

What you will Need –

  • Silicone molds. To make the chocolate balls, you’ll need a spherical silicone mold, such as a chocolate or baking mold. Just make sure that the hot chocolate balls will fit snugly into a standard-sized mug when they’re fully assembled for the ideal results– half-spheres measuring about 2 to 2.5″ in diameter will be your best option.
  • Chocolate. I use high quality chocolate melting wafers for this recipe instead of chocolate chips. Melting wafers are less likely to burn or harden too quickly.
  • Hot cocoa mix. Grab your favorite hot cocoa mix and go to town– a tablespoon per hot cocoa bomb is the perfect amount for a mug full of deliciousness.
  • Flavorful fillings. Mini marshmallows are a must, but you can also get creative with the other add-ins. Anything you like in your hot chocolate can go inside the sphere.

How to Assemble

  1. Melt the chocolate. Begin by melting your chocolate in the microwave or on the stove with a double boiler. Using a pastry brush or the back of a spoon, coat the inside of your spherical mold with the chocolate. Make sure you paint the entire sphere, otherwise each half won’t match up.
  2. Form the shell. Put the mold in the freezer for 5 minutes to allow the chocolate to harden. Brush with additional melted chocolate and freeze once more to build a thicker shell. Gently pop the chocolate shells out of the mold.
  3. Fill them. In one half of each hot cocoa bomb, add mini marshmallows and hot cocoa mix. Place a microwave-safe plate in the microwave and heat for about 90 seconds, then press the other half of your chocolate sphere on the hot plate to smooth and melt the edges. Quickly place it on top of the filled half of your cocoa bomb and you’ll have a fully assembled sphere!
  4. Decorate. From there, you can drizzle with additional melted chocolate and top with sprinkles for a pretty presentation.


  • 6 ounces milk chocolate melts
  • 1/3 cup hot cocoa mix
  • Mini marshmallows
  • 2 ounces dark chocolate melts for drizzling, as desired
  • Additional fillings and toppings, as desired
  1. Microwave the chocolate in a microwave-safe bowl for 30 seconds. Stir and microwave again, in 15 second intervals, stirring in between, until the chocolate is melted. Alternatively, melt using a double boiler on the stovetop.
  2. Using the back of a spoon or a pastry brush, fully coat the inside of a half-sphere mold with chocolate. Transfer to the freezer to harden for 5 minutes and then paint with a second layer of melted chocolate, concentrating especially around the edges and sides to thicken the shell. Place in the freezer once more until firm, about 5 more minutes. Repeat as needed if there are any thin spots or holes.
  3. Gently remove the chocolate half-spheres from the molds. Place half of the half-spheres in cupcake cups to hold steady and fill with 1 tablespoon of hot cocoa mix and marshmallows, as well as any additional fillings you’d like to include.
  4. Microwave a microwave-safe plate for 90 seconds. One at a time, take one of the remaining unfilled half-spheres and gently press and twist on the hot plate to melt and smooth the edges. Place on top of a filled half-sphere to create a whole sphere.
  5. If any gaps remain, use a butter knife to gently fill cracks and creases with melted chocolate from the hot plate.
  6. Drizzle with chocolate or decorate however you want.
  7. To serve, place a hot cocoa bomb in a mug and pour over very hot milk or hot water to melt the bomb. Stir to combine and enjoy!
