Hot chocolate bombs are chocolate spheres filled with hot chocolate mix and lots of marshmallows! Pour steaming hot milk over the top and watch the chocolate melt away and release those marshmallows into your milk. So much fun and makes a great gift!
I created this recipe back in 2019 when hot chocolate bombs were just beginning to be a thing. Originally posted by Eric Torres Garcia, who now has a cocoa bomb company! The idea went mega viral and soon everyone wanted to make cocoa bombs.
I noticed a lot of people making them were using low-quality chocolate or fake chocolate to make their bombs and having lots of problems. This recipe shows you how to make the most perfect hot chocolate bombs from high-quality, tempered chocolate that actually tastes delicious!

What Makes This Hot Chocolate Bomb Recipe Different
⭐⭐⭐⭐⭐
The difference between a hot chocolate bomb that looks store-bought and one that looks homemade comes down to properly tempered chocolate.
- Real, tempered chocolate. Tempered chocolate gives you a shell with a glossy shine and a snap instead of a soft, dull shell that can get white spots.
- Tempered in the microwave. No fancy equipment or seeding method needed. It only takes about 5 minutes with chocolate, a thermometer, and a little patience.
- Clean, flat seams. Leveling the shell edges on a warm plate makes the halves line up so your bombs look professional.
- Great for gifting. They keep at room temperature and look amazing in a mug with a bow on top.
Hot Chocolate Bomb Ingredients and Tools
Making hot cocoa bombs isn't too complicated, but there are a few tools and ingredients to make hot chocolate bombs you need to have on hand.
- Good quality chocolate. I like to use Callebaut, but any chocolate will work. Just remember, the better it tastes, the better hot chocolate bomb it will make!
- A thermometer to keep track of the temperature of your chocolate. Absolutely a must. Don't even attempt this without one. I'm using an infrared thermometer because it's a little bit easier to keep clean.
- Silicone sphere mold to make your bombs. I use a 2½" mold. This silicone sphere mold is the easiest to use if you're not familiar with tempering chocolate. I also show you how to use acrylic sphere molds in the recipe card below for you overachievers out there.
- Bench scraper if you are using an acrylic mold. You don't need a bench scraper for silicone molds.
- Spoon for smoothing the chocolate.
- Piping bag for sealing together the spheres and drizzling. I use these piping bags.
- Parchment paper to catch the extra chocolate.
- Hot chocolate mix of your choice. You can use any kind you like but we stick to the classic Swiss Miss flavor.
- Mini marshmallows of your choice. I like these mini marshmallows because you can fit a bunch in one bomb, making them more dramatic!
- Sprinkles to decorate the outside if you want. I like these Wilton sprinkles because they have a nice variety.
- Hot chocolate bomb labels. These hot chocolate bomb labels were made by my friend and they are so cute!
How to Make Hot Chocolate Bombs Step-By-Step
Here's a rundown on how to make hot chocolate bombs! This is such a fun thing to do with a group or with your family. The first thing we need to do is temper our chocolate. Tempering just means we are melting the chocolate at a controlled temperature so that it sets up again. If you've ever melted chocolate and it never set, or it grew weird white spots, you understand why tempering is important.
Don't worry, we're doing this the easy way in the microwave, and it only takes 5 minutes! Keep dark chocolate under 90º F, milk chocolate under 86º F, and white chocolate under 84º F. If you don't have a microwave or if you prefer, you can use the seeding method. Refer to the recipe card for exact amounts and the acrylic mold method.
If you're not comfortable with tempering chocolate, you can use Merckens compound chocolate. It requires no tempering, but it won't melt as easily in hot milk and has a slightly waxy taste.
- Chop your chocolate finely. Small, thin pieces melt at a lower temperature, which makes tempering much easier.
- Melt the chocolate in short bursts. Microwave at 50% power in 15-second bursts, stirring after each one, until it's about 75% melted. Keep your chocolate under 90º F the whole time.
- Stir until smooth. Keep stirring without heating so the warmth of the bowl melts the rest. If you still have lumps, microwave for 10 more seconds and stir until everything is melted.
- Fill your mold halfway. Spoon the tempered chocolate into each cavity of your sphere mold until it's about half full.
- Coat the mold up to the edges. Use a spoon to gently spread the chocolate all the way up the sides so the walls are evenly coated.
- Flip out and scrape the excess. Turn the mold upside down over parchment paper to empty out the extra chocolate (you can reuse it), then scrape the top clean.
- Let the shells set. Leave the mold upside down on parchment for 5 to 10 minutes. You can pop it in the fridge to speed things up, but it's not necessary.
- Release the shells. Press gently from the bottom of the mold to pop each shell out, and set them aside for assembly.
PRO TIP: Put your chocolate piping bag in a drinking glass that's been warmed for 1 minute in hot water or the microwave. It keeps the chocolate melted while you work and keeps your counter clean.
- Level the edges on a warm plate. Warm a ceramic plate in the microwave for a minute or two, then touch the edge of each shell to it to melt it flat and clean. Set the bottom halves in cupcake liners to hold them steady.
- Fill and seal. Fill the bottom shell with hot cocoa mix and marshmallows. Warm the edge of a top shell on the hot plate, set it on top, and hold for 10 seconds to seal.
PRO TIP: Wear gloves when you assemble. Warm fingers leave prints and melt the chocolate, and gloves give you much cleaner seams. If a seam still looks messy, cover it with your drizzle and sprinkles.
- Drizzle and decorate. Pipe a drizzle of melted chocolate over the bombs, then immediately add your sprinkles so they stick. Rewarm the chocolate for 10 seconds if it gets thick.
- Let them set and store. Once the drizzle sets, your hot chocolate bombs are ready to use or give away. Store them in an airtight container at room temperature.
How to Use Hot Chocolate Bombs
I tested these hot chocolate bombs out in various amounts of milk and found that 14 ounces was about perfect. I heat my milk until it's steaming (not boiling). Place the hot chocolate bomb in the bottom of the mug and pour the hot milk on top. The hot milk opens up the bomb, and all the marshmallows escape! So fun!
Use a spoon to stir so that the cocoa and chocolate melt into the hot milk.
Hot chocolate bombs make a great gift! Wrap them in a plastic bag with a fun tie and some instructions for use. Put it in a mug and give them as gifts for the holidays! Nothing says I love you like hot chocolate! For an even bigger holiday gift, add a bag of my Christmas crack recipe.
Hot Chocolate Bomb Flavor Variations
Hot chocolate bomb variations go beyond classic cocoa. Using flavored chocolate and switching up your sprinkles for crushed candies can change the flavor.
- Peppermint mocha. Add crushed candy canes with the marshmallows inside and to the drizzle on the outside.
- Salted caramel. Use caramel-flavored hot chocolate mix on the inside and crunched up caramel bits on the outside. I like this caramel flavored mix from Swiss Miss.
- Cookies and cream. Make your hot chocolate bomb shells using white chocolate and mix in crunched up Oreo cookies.
- S'mores. Add a few crunched up graham crackers to the drizzle and torch a few marshmallows, and voila! S'mores hot chocolate bombs!
- Mocha. Add a scoop of instant espresso mix into your hot chocolate bombs for an extra caffeine boost!
- Heart shaped. For Valentine's Day, try my heart hot chocolate bombs.
Common Hot Chocolate Bomb Problems To Avoid
- Shells won't release from the mold. This usually means the chocolate wasn't tempered. Tempered chocolate shrinks slightly as it sets and slides right out.
- Shells are too thin and break. Do two coats of chocolate so the walls are thicker and sturdier.
- Shells melt when you seal them. They're probably too thin. Make them a little thicker, and only touch the edge to the warm plate for a second.
- Messy seams or fingerprints. Wear gloves while you assemble, and cover any messy seams with your drizzle and sprinkles.
- Dull, streaky shells with white spots. The chocolate went over temper. Keep it under 90º F for dark chocolate, or re-temper it by seeding with more chopped chocolate.
Final Thoughts
I created this recipe back when hot chocolate bombs were just becoming a thing, and they're still one of my favorite holiday projects. They're so much fun to make with a group or with your family, and they make the best gifts. Use real chocolate, keep an eye on your thermometer, and you'll have shiny hot cocoa bombs that taste as good as they look.
Hot Chocolate Bomb FAQs
How long do hot chocolate bombs last and how should I store them?
They don't need to be refrigerated. Store them in an airtight container at room temperature, away from direct sunlight or heat. They'll last as long as the expiration dates on your chocolate, hot chocolate mix, and marshmallows.
Do I need to temper candy melts or almond bark?
No. Candy melts and almond bark don't contain cocoa butter, so you can't temper them. They harden on their own with no tempering, but they won't melt as easily in hot milk and they have a slightly waxy taste.
Can I use chocolate callets instead of a chocolate bar?
Yes, you can use callets. Just melt them in short bursts and keep checking the temperature so the chocolate doesn't get too hot.
Can you ship hot chocolate bombs?
Yes, you can ship them. Package them in tins inside cupcake liners and put shredded paper around them to keep them from breaking.
How much milk do I use for one hot chocolate bomb?
I use about 14 ounces of hot milk in a big 16 ounce mug. If you have a smaller mug, use less milk, but the hot chocolate will be stronger.

If you tried these Hot Chocolate Bombs or any other recipe on my blog, please leave a 🌟 star rating and let me know how it goes in the comments. I love hearing from you!
Recipe
Equipment
- Thermometer
- 2 ½" Sphere Mold (silicone or acrylic)
Ingredients
- 24 ounces semi-sweet couverture chocolate I prefer Callebaut, you can also use any high quality bar chocolate. You can use candy melts, if you're using a silicone mold but they don't taste as good.
- 1 cup mini marshmallows
- 6 Tablespoons hot chocolate mix
Instructions
For Silicone Molds
- Place the chocolate into a bowl and heat for 30 seconds (my microwave is 1000 watts)
- Stir the chocolate, moving the chocolate that is on the outside, towards the center.
- Heat again for 15 seconds and stir again.
- Repeat this process until the chocolate is ALMOST melted but not fully melted. Never heating for longer than 15 seconds and never going above 90F. If you go above 90º you will have to temper your chocolate by seeding (see my blog post for more info)
- Stir until fully melted.
- Fill your molds halfway with chocolate and use a spoon to smooth the chocolate up to the edges, taking care to make sure the walls are evenly coated.
- Turn the mold over and shake out the excess chocolate.
- Use a bench scraper to scrape off the excess chocolate.
- Turn the mold upside down onto the parchment paper and allow them to set up in the fridge for 10 minutes.
- Carefully remove the chocolate shells from the mold by gently pushing up from the bottom until the shell releases.
- Heat a ceramic plate and use it to smooth out the edges of the chocolate shells.
- Place the shells in cupcake liners for stability. Fill the shells with hot cocoa mix and marshmallows.
- If needed, warm the edge of the top shell once again on the plate and place it on top of the filled shell. Hold for 10 seconds to seal.
- Fill your piping bag with about ¼ cup of the leftover melted chocolate. Snip the tip off and drizzle chocolate over the hot chocolate bombs. Immediately top with some sprinkles.
For Acrylic Molds
- Chop your chocolate finely with a sharp chefs knife
- Add your chocolate to a bowl and microwave for 30 seconds (my microwave is 1000 watts)
- Stir the chocolate, moving the chocolate that is on the outside, towards the center.
- Heat again for 15 seconds and stir again.
- Repeat this process until the chocolate is ALMOST melted but not fully melted. Never heating for longer than 15 seconds and never going above 90F. If you go above 90º you will have to temper your chocolate by seeding (see my blog post for more info)
- Polish your mold with a paper towel to remove and residue from the inside to prevent the chocolate from sticking.
- Warm the acrylic mold slightly with a hair dryer or heat gun so it doesn't feel cold but not hot either.
- Pour the chocolate (at 90ºF) into the molds and tap on the table a few times to remove bubbles.
- Dump the chocolate back into the bowl, use the edge of your bench scraper to tap out as much of the chocolate as possible. You don't want the chocolates to be too thick.
- Scrape off the excess chocolate from the top of the mold back into the bowl.
- Turn the mold upside down onto some parchment paper to let the chocolate drain further and almost completely set. About 5 minutes. The chocolate should lift away from the parchment paper easily but still be soft.
- Scrape off the excess chocolate again and then place the mold into the freezer for 5 minutes.
- The freezer will cause the chocolate to contract and pull away from the mold. If it's not tempered, it will not contract and there will be no way to get the chocolate out. You can tell if your chocolate is tempered because if you look under the mold, it wont be stuck to the molds anymore. If you have a couple spots where it still is, it will be ok and still release with no problem.
- Quickly turn your mold over onto the table to release the chocolate from the mold. Now they are ready to assemble.
- Add 1 Tablespoon of hot chocolate mix to half the sphere and some marshmallows.
- Pipe some melted chocolate onto the top of the sphere at attach the top piece of the sphere. Pressing gently but firmly.
- Use a gloved hand to wipe away the excess chocolate for a clean look or roll in some sprinkles to finish decorating them!

I haven't tried out the recipe yet, although I am sure it is delicious! The 5 star rating is for your detailed instructions and photos. I have never seen a recipe explained as well as this one. I do make my own chocolate Easter eggs, salted caramels, and a few others. I learned so much from your tips especially how to double coat and what is the best kind of chocolate to use as I do prefer semi sweet rather than milk. I use melts but now that you explained how to easily temper it I will be changing my choice. Thank you so very much for all your tips.
Sugar Geek Show says
Thank you so much for your comment and the 5 stars, I'm glad you found all of my tips helpful! I always want to make my recipes easy for people to understand, and hope that everyone learns something new.
Mary W says
Holy Cow - not only is your YT vid great - your blog is as well! Great job! I never did understand what happened when I tried tempering choc and know I didn't go over 90 but it still turned into a rock. I kept heating it and adding liquid to try to salvage it - thanks to you I finally see what I did wrong. You rock and not in a seized choc way. LOL
Alice Carlson says
Great instructions. Very helpful. Thank you.
What about making homemade marshmallow to use in these. Any reason that wouldn't work? I am not sure if it would be too moist and clump the cocoa mix, but I think fresh marshmallow would taste better.
Elizabeth Marek says
That would totally work but you'd have to cut them pretty small 🙂
Dar says
Excellent instructions! My molds arrive in a couple of days and I will make my first attempt at these. I am using these as part of a goodie basket for friends for Christmas and can’t wait to try this!
PS - I’m in Hillsboro!
Jackie says
I love following you! Are you sure your molds are 2.5” and not 2”? I got them at 2.5 and the look way bigger than your pictures. Will it to be rich for one serving? I’m probably overthinking it...
Elizabeth Marek says
Mine are 2" but I know some people that go up to 3"
Jason says
Is it ok to use egg molds we could not find sphere?
Elizabeth Marek says
Yes thats totally ok
Shweta says
Great recipe and even better explanation of technique. I made these with chocolate chips. Made 2 bombs for kids. Definitely making more with high quality chocolate bars for gifting this holiday season.
Tricia M says
I love your tutorials, thank you! I have the Caullebaut 70.4%. Would this be okay to use for the hot cocoa bombs? If so, would it still have the same temperature range at the 90F max?
Elizabeth Marek says
I would do a test to see if it's fluid enough at 90ºF. Yes it's the same temperature range.
Aveline says
Thanks for this wonderful batch of information!! Can you use a grater to get the chocolate read instead of a knife?
Elizabeth Marek says
You could but it would be very difficult
Jody Mack says
Do you need a food safe brush?
Elizabeth Marek says
Any kind of paintbrush that is new and not used for paint
Jenny says
I just made these, and they turned out great! Thank you for such a clear and detailed recipe. I only had 10 oz of chocolate, so I figured I'd just make as many as I could, but I made 6 just fine. I found that I needed to leave them in the fridge for 10 minutes between each coat to be nice and shiny. Since I was short on chocolate, instead of using chocolate to "glue" them together, I rested each side on a warm pan for about 5 seconds to make them a little melty, put in the hot chocolate powder, cinnamon and marshmallows, and then stuck them together. I had a tiny bit of dark chocolate, so melted that and drizzled it over the top and added some gold sugar dust. SUPER cute and they were delicious! These will make fantastic Christmas gifts for neighbors and friends.
Dana Van Clieaf says
Thank you for the tutorial! This was a fun experiment but trying to keep the chocolate from solidifying on my brush and in the piping bag was a pain! I finally got a heating pad and put it on low on the counter and laid the piping bag on it. I put the bowl of chocolate over a small pot of warm water and that helped. Getting the chocolate thick enough in the mold is key and did have some trouble getting it melted enough at only 90 degrees.
I used Baker’s chocolate squares and we aren’t crazy about the taste of them. We’ll try again with a different brand if chocolate!
Elizabeth Marek says
Bakers chocolate is not make for melting, its used more for making chocolate cake and things like that. If you use a good quality eating chocolate you will have much better luck.
Ann says
Wait. 14 oz of hot milk??? Who has a mug that holds 14 oz of milk?
Elizabeth Marek says
All of my coffee mugs hold 16 oz of liquid. If you have a small mug, use less but the flavor will be very strong.
Tika says
Thank you for a clear tutorial. I cannot wait to try this with my family.
Where did you get your copper/glass mugs? they are super cute!
Elizabeth Marek says
I got them at William Sonoma
Ellen says
When making the chocolate bombs can you melt the chocolate in a double boiler on the stove ?
Elizabeth Marek says
If you do it that way then you will have to temper the traditional way, by seeding. See my chocolate tempering tutorial for more info. Skip down to the seeding method https://sugargeekshow.com/tempering-chocolate/
