Ingredients and tools needed to make hot chocolate bombs

hot chocolate bomb ingredients

  1. Good quality chocolate in bar form. Lindt semi-sweet chocolate or Callebaut are great options. I’m using Callebaut because they sell it in the bulk foods section of my WINCO. 
  2. Food thermometer to keep track of the temp of your chocolate. Absolutely a must. Don’t even attempt this without one. You can buy food thermometers at the grocery store in the kitchen supplies aisle. I’m using an infrared thermometer because it’s a little bit easier to keep clean. 
  3. Silicone sphere mold to make your bombs. This is the easiest mold to use if you’re not familiar with tempering chocolate. I will also show you how to use acrylic sphere molds for you over-achievers out there. 
  4. Bench scraper if you are using an acrylic mold. You don’t need one for silicone molds.
  5. 1/4″ paintbrush for applying chocolate to silicone molds. If you’re using an acrylic mold you won’t need one. 
  6. Piping bag for sealing together the spheres. 
  7. Parchment paper if you’re using an acrylic mold.
  8. Hot chocolate mix of your choice. 
  9. Mini marshmallows of your choice. I’m using rainbow marshmallows from Target.
  10. Sprinkles to decorate the outside if you want.

Here’s a rundown on how to make hot chocolate bombs!

  1. Chop chocolate (high-quality bar chocolate is best)
  2. Temper your chocolate (don’t worry, we’re doing this the easy way in the microwave and it only takes 5 minutes)
  3. Paint the chocolate into your silicone molds (two coats) or pour it into your acrylic mold. 
  4. Remove the chocolate spheres from the mold.
  5. Fill the molds with hot chocolate and marshmallows
  6. Seal the two pieces of chocolate together with more melted chocolate
  7. Decorate the seam with sprinkles!

What chocolate is best for making hot chocolate bombs?

You want to make sure you’re using good quality chocolate that has cocoa butter in it and not too many other ingredients or the chocolate isn’t going to melt right. You can use candy-melts but the taste is going to be more like wax and not melt very well in your hot chocolate. Chocolate chips are also not going to work very well. 

If you are going to use candy melts or another candy coating then you’ll definitely want to use the silicone mold and not the acrylic mold. 

If you’re really serious about making cocoa bombs to sell, you’ll want to get some couverture chocolate which is made to melt really smoothly and use in chocolate molds. 

If you don’t have time to order some good couverture chocolate then look for some chocolate bars at your grocery store that is 65% cocoa or more. Check the ingredients to make sure it contains cocoa butter. 

Do I have to temper my chocolate?

tools for tempering chocolate

If you’ve never heard of tempering your chocolate or feel intimidated, don’t worry. Tempering just means that you are controlling the heat of your chocolate while melting it to make sure it’s as strong as possible. Heating and cooling to exact temperatures which we will track with our thermometer.

Tempering your chocolate is really important. Un-tempered chocolate is soft, doesn’t have a shine, and has a problem holding its shape. It will melt at room temperature and just overall be a huge headache to work with. Candy melts were invented to avoid tempering but the taste really suffers. Don’t worry, I’m going to show you how to temper your chocolate in the microwave the easy way and it only takes 5 minutes!

What mold is best for making hot chocolate bombs?

I’m going to show you how to use two molds, a silicone mold, and an acrylic mold. I thought that I had to use an acrylic mold to get that ultimate shine but to be honest, after decorating I’m not sure I could even tell the difference between the two.

So I would say if you had to choose, the silicone mold is better because it’s basically foolproof. The silicone mold is also cheaper. The downside is that it takes a bit more time to hand paint each mold so if you’re making a lot, you might want to go with the acrylic mold. 

I’ve seen some people use some really big molds and I understand why people like to use them because you can fit more things in them. But keep in mind that you want the amount of chocolate, hot cocoa, and marshmallow to be proportionate to how much milk you have in your mug so that the taste is not affected. 

My molds are 2 1/2″ in diameter and fit about 1 Tablespoon of the hot cocoa mix inside which is plenty when combined with the extra marshmallows and chocolate. 

How to make hot chocolate bombs step-by-step

Step 1 – Chop 24 ounces of good quality semi-sweet chocolate as finely as you can with a knife. This is kind of tedious but I promise it’s worth it! You don’t want ANY big chunks.

Step 2 – Place the chocolate in the microwave and heat for 30 seconds. NO MORE. Then stir with a spatula, moving the chocolate from the outside edges, to the center to evenly heat it. 

Step 3 – Place the chocolate back into the microwave and heat for 15 seconds and stir like we did in the first step. Take the temp of your chocolate to make sure it’s not above 90ºF.

Step 4 – Repeat this process 2-5 more times until the chocolate is almost melted. Never heat more than 15 seconds and do not let your chocolate get above 90ºF. Once almost melted, just continue stirring until the chocolate is fully melted from the residual heat from the bowl.

Step 5 – Pour some chocolate onto some parchment paper and pop it into the fridge for 5 minutes. Take it out and observe it. Does it look shiny? Does it snap in half loudly when you break it? Then it’s tempered and ready to go in your molds.

If your chocolate is dull, has white residue on top or just bends when you try to break it, it’s not tempered and you may have heated it too far. Don’t worry, you can seed it with more chopped chocolate. Just add in 6 ounces of finely chopped chocolate and stir until melted. You may need to heat for 5-10 seconds to get it fully melted. Test again before using. 

Pro-tip – No microwave? You can temper your chocolate the old-fashioned way. I go over it in my chocolate tempering tutorial. 

Molding the chocolate spheres with a silicone mold

Step 1 – Clean your mold. Use some paper towel to thoroughly polish the insides of your molds so that they are nice and shiny. Any amount of residue will cause a blemish on your chocolate. This is true for silicone molds and acrylic molds.

Step 2 – Paint a thin layer of chocolate using a paintbrush on the inside of the mold. Place into the fridge for 5 minutes to set.

Step 3 – Apply a second coat of chocolate, paying special attention to the edges to build them up a bit so the molds have a strong edge. Place the chocolate mold into the fridge to set up for five minutes.

After 5 minutes your chocolate will easily release from the mold and are ready to be assembled!

Molding the chocolate spheres with an acrylic mold

Using an acrylic mold has a few more steps but the shine is incredible and is much faster than using a silicone mold. 

Step 1 – Use some paper towel to thoroughly polish the insides of your molds so that they are nice and shiny. This also prevents chocolate from sticking. 

Step 2 – Warm your mold slightly with a heat gun or hair dyer to just take the chill off the acrylic. It shouldn’t be hot at all. Warming the mold prevents the chocolate from getting hard too quickly.

Step 3 – Make sure your chocolate is at 90ºF and pour it into the mold. Tap the mold against the table a couple times to release any bubbles.

Step 4 – Pour the excess chocolate out of the mold back into the bowl or onto the table to be scraped up later. I use the edges of my bench scraper to tap the side so that the chocolate all comes out.

Step 5 – Scrape the excess chocolate off the top of the mold.

Step 6 – Place the mold face down onto some parchment paper until it’s almost set but still soft. About 5 minutes. This allows the excess chocolate to pool onto the parchment paper to build up the rim of the chocolate.

Step 7 – Scrape the top of the mold again to make the chocolate spheres have a very clean edge.

Step 8 – Place the chocolate mold into the freezer for 5 minutes (don’t forget about them!)

Step 9 – If the chocolate was tempered properly, you will see that the chocolate has pulled away from the mold and is not sticking. You might have one or two spots that are sticking but if they are small, it will be ok.

Step 10 – In one swift move, turn the mold upside down onto the table with a bit of force to get the chocolates to all come out.

Assembling the chocolate bombs

Step 1 – Set your first half into a small bowl or use the back of your silicone mold to hold it. Fill the chocolate about 3/4 of the way with your favorite hot chocolate mix and marshmallows.

Step 2 – Pipe some melted chocolate onto the top of the sphere.

Step 3 – Place the second half of the chocolate sphere on top and press gently together to seal. 

Pro-tip – Use gloves to avoid getting too many fingerprints on your hot chocolate bombs. 

Step 4 – Use a gloved finger to clean off the excess chocolate to make a seamless look or simply roll the bomb in spriles to finish the look.

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 cream opens up the bomb and all the marshmallows escape! So fun!

Use a spoon to stir so that the cocao 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!

Cook Time: 5 mins
Cooling: 10 mins
Serves: 6 spheres
Calories: 87kcal

Ingredients

  • 24 ounces (680 g) 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 (50 g) mini marshmallows
  • 6 Tablespoons (88 g) hot chocolate mix

Equipment

  • Thermometer
  • 2 1/2" Sphere Mold (silicone or acrylic)

Instructions

For Silicone Molds

  • Finely chop your chocolate using a sharp chefs knife
  • 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)
  • Make sure your molds are clean by polishing them with a paper towel
  • Paint a thin layer of chocolate into the molds and refrigerate for 5 minutes
  • Paint a second coat of chocolate over the first, paying special attention to building up the rim of the sphere. Refrigerate for 5 minutes.
  • Take your chocolate out of the molds and fill with 1 tablespoon of hot cocoa mix and marshmallows
  • Pipe some melted chocolate around the rim and attach the second sphere on top. Pressing gently to seal.
  • Use a gloved hand to wipe away the excess chocolate or simply roll the chocolate sphere in some sprinkles to finish the look.

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 doesnt 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!

Notes

TIPS FOR SUCCESS!
The Best Chocolate - Semi-sweet couverture chocolate or high quality bar chocolate. Not candy melts, chocolate chips or candy coating.  
Hot Chocolate Bomb Mold - Silicone molds or acrylic molds work well. Silicone is the easiest but takes longer. Acrylic is more complicated but you can do more at once. 
Thermometer - You will need a simple kitchen thermometer or infrared thermometer to track the temperature of your chocolate.
