Hot Chocolate Bombs are fun little chocolate balls filled with cocoa and marshmallows. Just drop them in warm milk, and watch the magic happen as they melt and make your drink extra cozy!
Honestly, they’re like tiny surprises in a cup! I love making a few extras to enjoy with friends or to gift during the holidays. Who wouldn’t smile with a cup of hot chocolate in hand? ☕️
Key Ingredients & Substitutions
Chocolate: Semi-sweet or milk chocolate works best for melting and creating that perfect shell. If you’re looking to make it dairy-free, try dark chocolate or a dairy-free chocolate chip option.
Hot Cocoa Mix: You can choose from store-bought mixes or make your own using cocoa powder, sugar, and a pinch of salt. Adjust sweetness to your liking—some prefer it sweeter!
Mini Marshmallows: These are a classic for filling; however, you can swap them for crushed peppermint or caramel bits for a twist. If you’re avoiding marshmallows, try dairy-free options or skip them entirely!
Decoration: While sprinkles are fun, you could also use crushed nuts, coconut flakes, or colorful candy bits to brighten them up. Personalize it to suit your taste!
How Do I Perfectly Mold the Chocolate Shells?
Molding chocolate shell can be a little tricky but it’s essential for a good hot chocolate bomb. Here are some handy tips:
- Start with high-quality chocolate; it melts smoother and tastes better.
- Use a silicone mold for easy release. Make sure it’s clean and dry before adding the chocolate.
- After melting, let the chocolate cool slightly before placing it in the molds; this helps avoid bubbles.
- Spread the chocolate evenly up the sides, making it about 1/8 inch thick for stability.
- After refrigerating, if the shells are too thin, just recoat them with another layer of melted chocolate.
Be patient with the process; it’s worth it when they come out beautifully!

How to Make Delicious Hot Chocolate Bombs
Ingredients You’ll Need:
For the Bombs:
- 12 oz (340 g) semi-sweet or milk chocolate, chopped or chips, divided
- 1 cup hot cocoa mix (your favorite brand or homemade)
- 1 cup mini marshmallows (plus extra for topping)
For Decoration (Optional):
- Sprinkles
- Crushed candy
- Toffee bits
How Much Time Will You Need?
You’ll need about 30 minutes to prepare and assemble the Hot Chocolate Bombs, plus about 15-20 minutes for the chocolate to set in the fridge. Overall, it’s a straightforward process, and the waiting is well worth it for a cozy treat!
Step-by-Step Instructions:
1. Melt the Chocolate:
Start by dividing the chocolate into two portions: 8 oz for the shells and 4 oz for decoration. Melt the 8 oz portion in a microwave-safe bowl using 20-second intervals, stirring well in between until it’s smooth. You can also melt it gently in a double boiler if you prefer.
2. Mold the Shells:
Grab a silicone half-sphere mold, which is about 2.5 inches in diameter. Spoon in about 1-2 tablespoons of melted chocolate into each half. Use a spoon to swirl and spread the chocolate evenly across the insides of the mold to create a shell that’s about 1/8 inch thick.
3. Set the Shells:
Put the filled molds in the refrigerator for about 10-15 minutes, or until the chocolate is hard. If you want stronger shells, you can repeat coating with another layer of melted chocolate.
4. Remove Shells:
Once set, carefully pop the chocolate half-spheres out of the mold. Be gentle to avoid breaking them!
5. Fill the Bombs:
Take one of the half-spheres and fill it with approximately 1 tablespoon of hot cocoa mix and a small handful of mini marshmallows.
6. Seal the Bombs:
Warm a plate in the microwave just slightly (not too hot!). Use this plate to gently melt the edge of an empty half-sphere. Quickly place it on top of the filled half-sphere, pressing gently to fuse the edges together. If needed, use a little melted reserved chocolate as “glue” to completely seal them.
7. Decorate:
Melt the remaining 4 oz of chocolate and drizzle it over the top of each bomb. While the chocolate is still wet, add mini marshmallows, sprinkles, crushed candy, or toffee bits for decoration.
8. Chill and Store:
Place the bombs back in the refrigerator for about 10 minutes to firm up the decorations. Once set, store them in an airtight container at room temperature until you’re ready to use them.
9. Serve and Enjoy!
To enjoy your hot chocolate bomb, place one in a mug. Heat 8 oz (1 cup) of milk until it’s hot (but not boiling). Pour the hot milk over the bomb and watch it melt, releasing the cocoa mix and marshmallows inside. Stir well and savor your rich, creamy cup of hot chocolate!
Enjoy cozying up with these decadent and fun-to-make Hot Chocolate Bombs!
Can I Use White Chocolate for the Bombs?
Absolutely! White chocolate works wonderfully, but keep in mind that it may require a slightly different melting temperature. Be vigilant while melting, as white chocolate can burn more easily than darker chocolates.
How Should I Store Leftover Hot Chocolate Bombs?
Store your hot chocolate bombs in an airtight container at room temperature for up to 2 weeks. If you’re in a humid environment, consider refrigerating them to maintain the chocolate texture, but allow them to come to room temperature before serving for the best flavor.
Can I Add Flavorings to the Cocoa Mix?
Definitely! You can customize the hot cocoa mix by adding spices like cinnamon or nutmeg for warmth, or even a splash of vanilla or peppermint extract for a seasonal twist. Just mix these into the cocoa powder before filling the bombs!
What if My Chocolate Shells Are Too Thin?
If your shells feel too thin and fragile, simply melt a bit more chocolate and coat the insides of the molds a second time. This will create sturdier shells, making it easier to handle and seal the bombs without breaking them.
