Hot Chocolate Bombs

The title of these balls of chocolate is pretty accurate. The balls are filled with chocolate milk powder and marshmallows. When hot milk is added to the bombs, they open up, or ‘explode’ to let the hot chocolate mix and marshmallows out. When stirred, you have a decadent and delicious cup of hot chocolate! If you love hot chocolate, I also have a Big Batch of Hot Cocoa Mix that you will want to have on hand for any time you are craving a mug of hot cocoa. Or, fill these bombs with my White Hot Chocolate Mix, too! I also have Peppermint Hot Cocoa Bombs you might love.

Hot Cocoa Bomb Ingredients

Can I tell you what makes my hot cocoa bombs better than the rest? HOMEMADE CHOCOLATE MILK POWDER! This is going to produce the BEST cup of Hot Chocolate that you will ever make. And I have made a LOT of hot chocolate, so I feel confident you will agree!

I used my homemade chocolate milk powder recipe, which is only three ingredients that you probably already have on hand. And it will make the richest flavor for your hot cocoa bomb!

To make the powder, combine the three ingredients–sugar, cocoa powder, and a pinch of salt. You can blend them in a food processor or shake them in a container that has a lid (of course). Store the powder in an airtight container in a cool, dry place until you are ready to use it.

Chocolate Melting Methods

There are a couple of ways you can melt chocolate. You can melt it in the microwave or use the double boiler method.

Melting Chocolate in the Microwave

To melt the chocolate in the microwave, add the chocolate to a microwave-safe bowl. Heat the chocolate in 20-second increments, stirring after every 20 seconds, until melted.

Double Boiler Method for Melting Chocolate

Using the double boiler method helps ensure that the chocolate is not burned and the gently melted chocolate will be smooth and shiny. And, you don’t need any fancy kitchen gadgets to use this method. 

To melt the chocolate, fill a pot about halfway full of water. Bring it to a simmer over low heat. Find a heat-safe bowl (glass or stainless steel) that can be set into the pot. Make sure the bottom of the pot is not touching the water. The steam is what will melt the chocolate.

How to Store

I recommend only making as many chocolate bombs as you need. They are best used right away or within 24 hours and stored at room temperature.

Cup of Hot Chocolate Using Hot Chocolate Bombs

Rudolph Hot Cocoa Bombs

This was so much fun! I used some extra chocolate from the melting chocolate and added it to a piping bag. Snip off the corner of the tip of the bag and then pipe out little antlers. Let those harden, for about 5 minutes.

I used the piping bag to add a little bit of chocolate to the cheeks, then pressed a snowflake sprinkle into the chocolate. Same for the nose, however, I used a red chocolate candy.

Attach the antlers (use gloves to avoid fingerprints) using some melted chocolate and hold in place until the chocolate hardens. (about 30 seconds)

I saw this on Pinterest and tried to track down the creator, but wasn’t able to. If you are the creator of this adorable design, please let me know so I can give you credit!

Hot Chocolate Bombs

Prep Time 20 minutes
Freeze 10 minutes
Total Time 30 minutes
Hot Chocolate Bombs are chocolate spheres filled with homemade chocolate milk powder and marshmallows that are put into a mug with hot milk for a delicious cup of hot cocoa.

Ingredients

Chocolate Milk Powder

  • â…” cup (133 g) granulated sugar
  • â…“ cup (39 g) cocoa powder
  • 1 pinch kosher salt

Chocolate Bombs

  • 1 cup (168 g) semi-sweet chocolate chips
  • 6 tablespoons chocolate milk powder, divided
  • 3 tablespoons mini marshmallows, divided
  • 1 silicone chocolate bomb mold

Instructions

Chocolate Milk Powder

  • To get started, get out a jar with a lid or a food processor.
  • Combine the sugar, cocoa powder, and salt. Use a food processor or shake up the ingredients in a sealed container until all the ingredients are mixed together. Store in a sealed container in a cool, dry place.

Melting Chocolate–Double Boiler Method

  • Fill a medium pot almost halfway with water. Bring the water to a simmer over low heat.
  • Place a heat-safe bowl (glass or stainless steel) that can just fit on top of the pot of simmering water, but leaves a gap between the water and bottom of the bowl.
  • Add the chocolate chips to the bowl. Keep the heat on low and use a rubber spatula to stir the melting chocolate chips until smooth. Remove the bowl of chocolate, but leave the water in the pot to be used later.

Chocolate Molds

  • Add a heaping spoonful of the melted chocolate to each of the six chocolate molds. Use the spoon to spread the chocolate up the sides of each mold. Make sure the entire inside of each mold is evenly coated with chocolate. (Save extra chocolate to use later.)
  • Freeze the chocolate for 10 minutes, or until completely set.
  • Once set, carefully remove the chocolate cups from the mold, placing them on a baking sheet lined with parchment paper.

Assembling Hot Chocolate Bombs

  • Flip over three of the molds to be filled. Fill each of the three halves with 2 tablespoons of the chocolate milk powder and 1 tablespoon of mini marshmallows.
  • Place the other three halves, seam-side down, on a separate baking sheet. Place the sheet on top of the pot of warm water over low heat to slightly melt the rims of the molds.
  • With gloves on (so you don't leave fingerprints) cover each filled chocolate half with an empty half, sealing it.
  • Decorate with any extra melted chocolate, sprinkles, and other candies. Use immediately, or within 24 hours, for best results. Store at room temperature.
  • To make hot chocolate, add a chocolate bomb into a mug. Slowly pour about 1½ cups of hot milk over the bombs and stir. Sip and enjoy!

Notes

If you are using white chocolate to make the bombs, be sure to get as good of quality as you can find, as white chocolate is very finicky!

  1. I can’t wait to make most of these recipes. They sound better then I can imagine and I have a wild imagination. I will get back to you after the holidays to let you know how they come out, which I am sure will be great. Happy holidays and great baking.

    1. Just popped some white chocolate morsels in a plastic disposable pastry bag, heat it in the microwave in 15-second increments and massaging the chocolate, then when it is melted cut the tip off of the pasty bag and pipe. You can re-heat if needed.

  3. I would love to make some chocolate boom with my daughter and my granddaughter and also make some cookie with them also

  4. What size are the chocolate balls? (I can’t help but hear chef from South Park singing here…😜) There are a ton of mold sizes! Thanks! And Merry Christmas!

    1. They are about 3 inches across. I used the biggest mold! (Lots of marshmallows fit in then!) You can use any size, and most shapes work!
