How to Make DIY Hot Cocoa Bombs with Marshmallows

Homemade DIY hot chocolate bombs

Have you seen any of the viral videos going around with the magical hot chocolate bombs?

You put a round, chocolatey hot cocoa bomb in the bottom of a mug, pour hot milk or plant milk over it, and it explodes into a magical, chocolatey drink with marshmallows and toppings floating in it.

While you can buy pre-made bombs in stores or on Etsy, they can get spendy!

You could spend up to $5 for a hot cocoa bomb or even closer to $15 for some extra fancy ones like unicorn hot chocolate bombs!

If you are moderately crafty, though, you can make your own DIY hot chocolate bombs and they will have less sugar and cost much less than storbought hot cocoa bombs.

What is a hot chocolate bomb?

A hot chocolate bomb (or hot cocoa bomb) is a thin chocolate or candy shell filled with cocoa powder and other hot chocolate toppings like marshmallows, sprinkles, candycanes or candy.

When you pour hot milk over a hot chocolate bomb, the heat from the liquid melts the shell, causing it to break open and release its fillings. The shell also melts into the hot liquid and becomes part of the beverage itself!

The result is a super creamy, rich hot chocolate beverage!

Where can I buy hot chocolate bombs?

While hot chocolate bombs aren't hard to make, if you'd really just rather buy them, I would check out all the hot chocolate bombs for sale on Etsy or shop small at local businesses in your area! 

How much do hot chocolate bombs cost?

I've seen them sold for as little as $3 each but most seem to cost about $5. I have seen them for as much as $15 for super fancy ones!

You can make your own DIY hot chocolate bombs for less than $1 each, though!

Important to note: Exact amounts of ingredients needed or yield may vary depending on the actual silicone mold you use. Silicone molds come in all sizes, so if you don't use the exact same one we did, you may end up needing more or less of each ingredient.

You will also need 1 cup of milk or plant milk to pour over your finished hot cocoa bombs when you're ready to serve them! 

I recommend organic whole milk or almond milk for a creamier, full-bodied finish.

*While these are the exact molds that were used to make the hot cocoa bombs, it's worth mentioning that they did have a strong smell that was surprising when opening the package.

I triple washed them with soap then let them soak overnight in soapy water. As soon as they came out of the water they no longer had a smell and you could not taste anything off once using them.

Ingredients needed to make DIY hot cocoa bombs - melting wafers, marshmallows, cocoa powder and a round hot chocolate bomb silicone mold


Directions

How to make hot chocolate bombs step 1: 

Melt the wafers according to package instructions, aim for the chocolate to be just warm enough to fully melted but not be overly hot.

How to make hot chocolate bombs step 2: 

Scoop almost a full 1.5 Tbsp scoop of the melted chocolate (about 1.25 tablespoons) into each of these round cup molds.
Use a scoop to put melted chocolate into round sphere molds to make DIY hot chocolate bombs at home.

Use the back of your spatula to evenly spread the chocolate around the inside of the circle. 

Try to focus on keeping a good layer of chocolate at the top ridge for two reasons: 
  1. You’ll want a strong seam to help ensure the cups are strong, especially when removing from the mold, but also when connecting the two sides together in the final step.
  2. The melted chocolate will slowly move down to the bottom of the cup as it hardens.

How to make hot chocolate bombs step 3: 

Once the chocolate is evenly spread around each of the 12 cups, place filled molds into the freezer on a metal tray as that will help them be level AND help keep them cold longer when taken out of the freezer. 

Chill for about 15 minutes. 

How to make hot chocolate bombs step 4: 

Re-melt remaining chocolate as needed and use it to add a thinner second coat of chocolate to the cups. 

Focus on areas that appear to be thinner and again around that top ridge. 

The chocolate will harden quickly this time after having been in the freezer so try to work quickly. 

Place the tray in the freezer again for 5 to 15 minutes. 

How to make hot chocolate bombs step 5: 

Remove one silicone tray from the freezer at time. 

Carefully remove one chocolate cup at a time from the mold and set them face down onto the freezing cold tray.
Removing chocolate shells from a silicone mold. Set them aside on the cold metal tray.

I found that the chocolate came perfectly out of these molds and the melting wafers gave them a beautiful glossy look without having to temper the chocolate. 

Repeat with the second tray until all shells have been removed from the molds.

Set the tray with the 12 chocolate shell cups carefully back in the freezer while you heat a small pan or plate for the next step.

How to make hot chocolate bombs step 6: 

Place a small stainless steel pan on your stove and warm it on medium heat until you can feel it starting to get warm without touching it. Remove pan from heat.

You want to use the residual heat from the pan as you do this but please be careful to not burn yourself!

Remove your tray from the freezer and working with one cup at a time, let each cup sit in the hot pan face down long enough that it will start to melt the top rim of the cup to give you as smooth of a finished edge as possible.

Set them back on the freezing tray, open side UP this time, after you finish each one. Repeat for just 6 cups. 

How to make hot chocolate bombs step 7: 

Add up to 1/2 Tablespoon to 1 full Tablespoon of cocoa powder to six of the twelve cups on your tray (fill the six halves that you melted in the previous step). I used about ½ Tablespoon cocoa powder per cup. 

Add about 1.5 tablespoons of the mini marshmallows to the same six cups. 

You want them to have as many marshmallows as possible-but not so many that they’ll block you from being able to easily put on the other cup to close the ball.

Fun Variation options: This is the step where you can get creative and personalize the hot chocolate bomb fillings if you'd like! You could also add crushed candy canes, a shake of cinnmon, butterscotch chips, a caramel, or whatever fun fillings you can dream up!

How to make hot chocolate bombs step 8: 

Now repeat the same heating process we did above for step 6 for the unfilled chocolate cups that you have. 

This process goes quick, so work with just one cup at a time. Warm the empty cup on the radiant heat from a pan as above and set it on top of one of the filled cups to form a ball.

Pro tip: Be careful not to tip the filled cups over

Pro tip: Work quickly so the warmth of your hands doesn't cause the chocolate to start melting. 

Repeat until you have the 6 finished bombs.
