Hot chocolate bombs are fun, tasty treats filled with cocoa and marshmallows, all wrapped in a chocolate shell. Just drop one in hot milk, and watch the magic happen!
Who wouldn’t want to see chocolate explode? It’s like a mini party in your mug! I love making these with my kids; it’s always more fun when there’s a surprise inside! ☕️🍫
Key Ingredients & Substitutions
Chocolate: Use high-quality dark or milk chocolate for a rich flavor. Chocolate melts are a great alternative and easier to work with. If you’re looking for a dairy-free option, check out vegan chocolate options!
Hot Cocoa Mix: You can make your own by mixing cocoa powder, sugar, and a pinch of salt. For low-carb options, use stevia or a sugar substitute. Your choice can significantly change the sweetness!
Mini Marshmallows: If you don’t have mini marshmallows, cut larger marshmallows into smaller bits. You could even try flavored marshmallows for a fun twist!
Decorations: Sprinkles and candy can be tailored to any occasion or season. Use crushed candy canes for a holiday touch, or colorful sprinkles for birthdays!
How Can You Ensure Your Chocolate Shells Are Perfectly Sealed?
Sealing the chocolate shells is key to keeping your hot chocolate bombs intact. Here’s a simple way to get it right:
- Start with a warm plate. This will help melt the edge of the chocolate slightly when you press it against the filled half.
- Don’t rush! Take your time to gently press the two halves together. It should be snug but not too hard.
- Chill them again after sealing to make sure everything is set properly, ensuring no leaks!
Practice will make you a pro at making beautiful bombs. Each attempt gets easier, so have fun with it! Enjoy your hot chocolate adventures!

How to Make Hot Chocolate Bombs
Ingredients You’ll Need:
For the Bombs:
- 12 oz good-quality dark or milk chocolate (or chocolate melts)
- 1 cup hot cocoa mix (store-bought or homemade)
- 1 cup mini marshmallows
For Decoration:
- Sprinkles, crushed candy, or edible decorations
- White chocolate (optional, for drizzling and decoration)
- Small candies or sugar eyes for decoration (optional)
How Much Time Will You Need?
You’ll need about 30 minutes to prepare the hot chocolate bombs, plus an additional 30 minutes to chill them in the fridge. So, overall, you should plan for about 1 hour total, but keep in mind that they need to set in the fridge!
Step-by-Step Instructions:
1. Melt the Chocolate:
Begin by chopping the chocolate finely to help it melt evenly. Use a double boiler or microwave, melting in short bursts and stirring often until smooth. Be careful not to overheat the chocolate—it should be melted and glossy!
2. Coat the Molds:
Grab a silicone half-sphere mold specifically for chocolate bombs. Using a brush or spoon, apply a generous layer of melted chocolate into each mold cavity. Make sure to get it all around the sides. Place your mold in the fridge for about 10-15 minutes to let it set.
3. Add a Second Layer:
Once your first layer is firm, take the mold out and add another layer of melted chocolate. This will make your chocolate shells nice and sturdy! Put it back in the fridge until completely hardened.
4. Fill the Bombs:
Carefully remove the chocolate half spheres from the mold. Place half of the chocolate pieces on your workspace. Fill each one with about 1 tablespoon of hot cocoa mix and a good handful of mini marshmallows for that fun explosion!
5. Seal the Bombs:
To seal the bombs, slightly warm a plate (you don’t want it too hot, just warm enough to melt the chocolate edges) and press one empty chocolate half against it for a couple of seconds. Then, take this half and press it gently onto the filled half. Make sure to seal it well, and put it back in the fridge to set.
6. Decorate:
If you’d like, melt some white chocolate for drizzling over the tops for a pretty finish. While the white chocolate is still wet, add your chosen decorations, like sprinkles or mini candies, to make them extra festive!
7. Serve and Enjoy:
When you’re ready for a delicious treat, drop a hot chocolate bomb into a large mug and pour hot milk over it. Watch the magic as it ‘explodes’ and releases the cocoa and marshmallows! Stir it all together, and enjoy your warm, indulgent hot chocolate!
