Chocolate Bombs: An Adorable DIY Hot Chocolate Kit

The best way to win friends and influence people? Give them this adorable DIY hot chocolate kit. These chocolate bombs make the perfect gift any time of year. They are especially great around the holiday season and, of course, Valentine’s day! You can include cute mugs with the gift if you’re feeling extra friendly. The individual servings are the perfect sweet treat for a friend or, of course, your sweetie! It’s also the kind of hostess gift we could really get behind (hint, hint!). Inside the bomb, you can put your favorite hot cocoa mix, along with mini marshmallow. The chocolate exterior is much easier than it looks, and can be decorated with whatever seasonal sprinkles strike your fancy. Pour some milk over the hot chocolate bomb and watch it melt into a delicious steamy cup of hot cocoa!

A Very Short History of Hot Chocolate Bombs

Hot chocolate bombs seem to have exploded (pun intended) into existence in 2019. Several chocolatiers have laid claim to their invention. We’ll have to see who history (or wikipedia) declares the winner. Then, came Covid. And, really, there’s nothing like a pandemic-induced stay-at-home-order to make you obsessively watch videos of chocolate bombs melting on Tik Tok. Or were we the only ones who spent 2020 that way? In any case, the market for hot chocolate bombs has continued to grow explosively (yep, pun still intended) over the last year year or two. It may have peaked last Christmas with Disney’s amazing and viral Olaf-shaped hot chocolate bomb.

Perfecting Your Hot Chocolate Bomb

The nice thing about chocolate bombs is that they are endlessly customizable. You can decide what kind of chocolate to use for the exterior. You can use your favorite hot cocoa recipe. And, you get to decide whether or not you want to add fluffy marshmallows to your cocoa. You can even make homemade marshmallows. As an aside, we did this once during the pandemic and learned that we are bakers and not candy makers.

There are endless adorable chocolate molds on the internet that can be used, if a sphere isn’t getting you going. There is even, apparently, an entire Facebook group dedicated to hot chocolate bombs. We will refrain from posting this there, since we are clearly just hot chocolate bomb novices. We’re sharing our favorite homemade hot chocolate mix here, as well as instructions for how to go from mix to bomb, in just a few simple steps. BOMBS AWAY!

Servings 12 bombs


  • Silicon molds with 6 semi spheres
  • disposable piping bag
  • 1/16 inch piping tip


For the Hot Chocolate Mix Recipe

  • 1/4 cup regular sugar
  • 1/2 tbsp cornstarch
  • 1 1/2 oz semi or bittersweet chocolate
  • 1/4 cup dark cocoa powder
  • 1/8 tsp vanilla extract
  • pinch salt
  • 1/8 tsp cinnamon (optional)

For the Hot Chocolate Bombs

  • 2 cups chocolate candy melts or 8 oz semisweet chocolate, chopped
  • 1/2 cup white chocolate or colored chocolate candy melts
  • 1/2 cup mini marshmallows
  • sprinkles


For the Hot Cocoa Mix

  • Combine all ingredients in a food processor and blend until powdery.

For the Hot Cocoa Bombs

  • Melt the chocolate candy melts in a small bowl placed over a pot of simmering water. If you are using chocolate chips, you will want to temper the chocolate to make sure it's shiny and pretty. Candy melts don't need to be tempered.
  • To temper, you will need a candy thermometer. Melt two thirds of the chocolate to roughly 105 F. Then, add the remaining chocolate a little at a time, stirring to melt. Let the chocolate cool to 82 F. Once the chocolate has cooled to 82 F, put it back over the hot water and reheat to 88 – 91 F. Maintain the chocolate at this temperature.
  • Use a clean paint brush to brush the silicone molds with chocolate. Freeze 10 minutes to set.
  • Use gloves for this step to avoid fingerprints on your hot chocolate bombs. Heat up a frying pan on medium heat and gently melt the edges of one chocolate bomb half. Pop the chocolate bomb half into a cupcake paper or round cookie holder to hold it while you fill it. Fill with 1 tbsp hot chocolate mix and some mini marshmallows.
  • Melt the edges of the second half, then put the two halves together. The melted edges will seal.
  • Let the hot chocolate bombs rest for a few minutes. Melt the white chocolate or colored candy melts. Place the white or colored chocolate in a piping bag and pipe swirls over the hot chocolate bombs. Add some sprinkles!


For those who like their chocolate with spicy flavors, 1/8 tsp hot chili can be added to the hot chocolate mix recipe.
Hot Chocolate Mixture keeps in an airtight container (aka a chocolate bomb) at room temperature for up to 2 months.
If you’re not in the mood to make hot cocoa bombs, make a big batch so you can have a hot cocoa jar sitting in your kitchen. We hear this is the key to happiness.
The hot cocoa mix itself can be put into 4-ounce mason jars and given away as a lovely holiday gift as well.
Note that some hot chocolate mix recipes call for dry milk, so that you can skip the step of mixing in hot milk. While this can be practical, we find the flavor and texture a bit lacking, so prefer our milk liquid and hot and our hot chocolate mix dairy free.
To use: heat up one cup of your favorite kind of milk (dairy, almond, soy, oat, or whatever nut or pulse suits your fancy that day) over medium heat until steamy. Place your bomb in a mug and pour the hot milk over the top.
