These candy-filled hot chocolate bombs are such a fun (and totally delicious) way to turn ordinary hot cocoa into something magical! Once they touch the hot liquid, they’ll melt into a rich, creamy drink that feels like a hug in a mug. The best part? You can completely customize the inside with all your favorite mix-ins!

Homemade Hot Cocoa Bombs
I designed this DIY hot chocolate bomb recipe to be easy enough for beginners, with simple instructions and no fussy chocolate tempering. I use melting chocolate (also called almond bark or candy melts) to keep things low-stress and mess-free. Each hot cocoa bomb is filled with a classic mix of hot chocolate powder, chocolate chips, and mini marshmallows, but that’s just the beginning.
I love creating fun flavor combos using Reese’s Pieces, peanut butter M&M’s, butterscotch chips, espresso chips, and crushed candy canes. If you’re looking for hot chocolate bomb ideas, I’m here to give you a solid base plus tons of creative directions to try.

Prevent Cracks!
I tested multiple techniques for sealing these hot chocolate bombs to prevent cracking. The easiest method? Warm a plate in the microwave, melt the rim slightly, and gently press the two halves together. It works like a charm, even if you’ve never worked with chocolate molds before. I also recommend doubling up the chocolate on the rims for a sturdier seal, especially if you’re adding a lot of filling.

Hot Chocolate Bombs Recipe
Equipment
- Silicone Half-Sphere Mold
Ingredients
- 12 ounces melting chocolate
- 6 envelopes hot chocolate mix such as Swiss Miss
- ½ cup Reese’s Pieces *
- ½ cup chocolate chips
- 2 cups mini marshmallows
Instructions
IMPORTANT: Read through the recipe and notes sections before starting.
- In a medium microwave-safe bowl, melt just a few blocks at a time of the chocolate in 60-second increments, stirring each time.12 ounces melting chocolate
- Fill the molds by using the back of a spoon and moving the chocolate around the inside of the mold until it is completely covered. Once the chocolate has hardened, use the spoon to add an additional layer of chocolate around the rim of each mold. Once the chocolate has firmed, remove the half-spheres from the molds and repeat with the white chocolate, if you are making them as well.
- Once you have an equal amount of half-spheres, fill half with a spoonful of hot cocoa and a small spoonful of chocolate chips or candies, then add a few mini marshmallows.½ cup Reese’s Pieces, ½ cup chocolate chips, 6 envelopes hot chocolate mix, 2 cups mini marshmallows
- To attach the half-spheres together, microwave a small plate, for about 30 seconds, until it is warm. Place the rim of the empty side of the chocolate sphere onto the plate, until it just begins to melt, then quickly attach the half-spheres together. You may need to gently brush a small amount of chocolate around the seam, to make sure they are attached.
Notes
- Using 12 ounces of chocolate, I easily made 8-10 (2-inch) cocoa bombs. I also melt in small portions so it doesn’t have time to harden while I’m using the spoon to fill the molds.
- You can make these cocoa bombs with any kind of melting chocolate you can get your hands on. Milk, dark, white, or fun colors all work great! I prefer bars of chocolate, but candy melts will work too, although I think they’re less flavorful.
- You can leave the bombs undecorated, but to make them extra special, I like to drizzle over a different color of chocolate and then add some chopped candy to the top. They are easy to decorate to suit any occasion with different colors of candy and chocolate. And remember, sprinkles are never a bad idea!
How to Store
Store hot chocolate bombs in an airtight container at room temperature or in the refrigerator for up to 2 weeks. I like to place one in a glass of warm milk, but you can also pour the milk over the cocoa bomb for a faster melting effect.
