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.

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!

Hi, Very excited to try these out. Do you just use the standard mini size marshmallows inside the bombs or are they smaller than mini. If so where do you buy them and if online would you happen to have a link you could share?
Thanks!
Elizabeth Marek says
I used mini and dehydrated. You can buy them online or you might find them in store
Katie says
Do you by chance sell these? My brother lives in Portland, so I was thinking of sending him some for Christmas.
Elizabeth Marek says
Sorry I don't
Khrisi Thiele says
Thank you for your video. It was very helpful. I'll be making these as soon as I receive my molds. What brand of sprinkles did you use? Everything I'm finding online looks a bit big and I loved the colors you used. Thank you!!
Elizabeth Marek says
I combined some sanding sugar and some non-perils
Joanna says
I cannot find the block chocolate with cocoa butter. I see sugar, cocoa beans & soy lecithin all over, but not one with cocoa butter. Thoughts on that?
Elizabeth Marek says
You might have to buy online
Wafaa Alwawi says
Thank you!!
Is one tablespoon of hot chocolate powder enough for a cup? Can I add more?
Thank you!!
Elizabeth Marek says
It is enough because you area also adding the chocolate from the cocoa bomb and sugar from the marshmallows
Yasmin Walters says
Just made these tonight! They came out perfect!!!!!!!! Thank you so much! My boys loved them.
Harriette Janicek says
Can you share other recipe combinations, like maybe adding Caramels to this or how about adding Cherry gelatin along with the cocoa mix to make a Cherry/Chocolate bomb.
Brandi Montelongo says
I’m excited to try this recipe out! I’m nervous about tempering the chocolate! Can you tell me the different temperatures for the different colors please. Going to give them away to family
Elizabeth Marek says
Here is my blog post on tempering different types of chocolate https://sugargeekshow.com/tempering-chocolate/
Katie Lester says
I am excited as well to try this and it is my first time temoering chocolate. Would almond bark be considered candy coating? I am looking for the chocolate and noticed that with the chocolate chips. Thank you so much for your tutorial and answering our questions! I am definitely a fan!
Elizabeth Marek says
Yes almond bark is candy coating, not real chocolate. Its ok to use with silicone molds but not acrylic molds
Brandi Montelongo says
I can’t wait to try this! Little nervous about Tempering the chocolate! But can you let me know the different temperatures for The difference chocolates? (Ex: Dark, white, and milk, any others if I missed some)
Elizabeth Marek says
I have updated the blog post to include temperatures for milk chocolate and white chocolate
Deb Thatcher says
I know you said you could use either milk or water. If you used water what happens to the chocolate then? Wouldn’t it seize up rather than melt like it would with milk? I can’t wait to try this recipe. I just ordered my silicone molds!!
Sugar Geek Show says
If you use hot water it just won't taste as good, milk is best 🙂
Chelsea says
Do you use regular mini marshmallows or dehydrated? I am hoping to do these in mugs for everyone for xmas this year! They look like so much fun!
Sugar Geek Show says
I used the dehydrated ones that came in the cocoa box mix and added a few regular mini marshmallows as well!
MB says
I wonder if you could fill them with Bailey’s? They would have to be in the refrigerator but do you think it could work for an adult version?
Sugar Geek Show says
Oooh yum I don't see why not!
Emma says
Hi love the recipe for the chocolate bombs. Please could you tell me what the temperature to reach is if using callebaut milk choclate.
Thanks
Sugar Geek Show says
Hi! Thank you, milk chocolate should never go above 84F-86F.
Dana says
Could you please share where the mugs came from? TIA!
Elizabeth Marek says
I got them on clearance from William Sonoma last year
