Celebrate Valentine’s Day by sharing Conversation Heart Hot Chocolate Bombs with your sweetheart or family and friends. Each brightly colored heart-shaped hot cocoa bomb is filled with tiny marshmallows and white hot chocolate mix. Melt them in hot milk to make a warm and cozy winter beverage.
My recipe to make hot chocolate bombs was so popular that I couldn’t wait to share more holiday-themed hot chocolate bombs with you.
It’s usually freezing here in Ohio on Valentine’s Day, so I thought it would be the perfect holiday to make and share more hot chocolate bombs with family and friends.
There are a lot of options when making and decorating Valentine’s Day hot chocolate bombs.
You can make round hot chocolate bombs and drizzle them with chocolate and top them with red heart sprinkles.
You could also make white chocolate bombs and drizzle them with red or pink chocolate and top them with a heart-shaped candy.
Or you can make chocolate heart-shaped hot chocolate bombs.
But my favorite option is to make them look like conversation heart candies.

When I set out to make these I was originally going to use the heart-shaped silicone molds that I used to create my Conversation Heart Cheesecakes, knowing many of you already had purchased that mold.
Unfortunately, the heart-shaped chocolate bombs would have been larger than a cupcake. They wouldn’t fit into a standard coffee mug.
And the silicone molds I used to make Conversation Heart Fudge were too small.
Then I remembered I had some plastic candy molds from Spinning Leaf that would be perfect.
Spinning Leaf makes candy molds that are meant to be filled with chocolate and an OREO Cookie.
Their candy hearts oreo cookie chocolate molds are 2 1/2 inches in diameter and 3/4 inch thick.
The white chocolate bombs made using these molds fit perfectly into a standard coffee mug.
When melted in 6 to 8 ounces of hot simmering milk, they make a rich and creamy cup of white hot chocolate that will delight your tastebuds.
As an added bonus, your cup of hot chocolate will be a pretty conversation heart color.
I even used brightly colored dehydrated cereal marshmallows to make the cups of white hot chocolate even more colorful.
To make these conversation heart bombs you’ll need:
- candy melts
- dehydrated marshmallows
- white hot chocolate mix
I used colored Wilton Candy Melts to make these heart-shaped treats. Candy Melts are compound chocolate (also known as confectionery coating) made using palm kernel oil. They melt and harden easily and come in a variety of colors and flavors.
You can, if you prefer, use pure white chocolate (made with cocoa butter). Just be sure to temper the pure white chocolate.
If you don’t have a lot of experience working with candy melts or pure chocolate, be sure to read my chocolate making tips page for detailed melting and tempering instructions.
Notes about colored Candy Melts:
- Some of the colored candy melts are very vibrant.
- If you want more pastel-colored conversation hearts then blend some white candy melts into the colored candy melts.
- You can melt the colored wafers with the white wafers or you can melt a bowl of white candy melts and stir the melted wafers into the melted colored wafers until you get the desired shade.
- I added white to the yellow, blue, green, and lavender candy melts.
- Be sure to use Bright White Candy melts when adding them to the blue, pink, and lavender candy melts. If you use the traditional white candy melts that are cream-colored, they will add a tint of yellow to the candy which is fine for green, yellow, or orange.
Coloring White Candy Melts
- If you prefer, you can color white candy melts or pure white chocolate using oil-based candy coloring.
- Squeeze one drop of coloring into a bowl of white chocolate then stir. Add more drops of coloring until you get the desired shade.
- Use bright white candy melts when making blue, pink, or purple. Cream-colored white wafers are fine to use when making yellow, orange, green, or red.
- Red is a very difficult shade to achieve, so I do recommend you buy colored red candy melts. If you use coloring, you may need to use a large amount to get a vibrant red.
- When coloring chocolate or candy melts you must use oil-based candy coloring that is specifically made for chocolate.
- DO NOT USE water-based icing colors or grocery store variety liquid food colors.
- These brands of candy coloring are all good to use:
- The soft mini marshmallows you find in bags at the grocery store are too large to fit into these conversation heart hot chocolate bombs.
- You need to use tiny dehydrated marshmallows instead. They are about a 1/4 of the size of a mini marshmallow.
- Dehydrated marshmallows are a bit crunchy but they soften as soon as they are hydrated with liquid.
- I used colored cereal marshmallows and separated them so each heart was filled with matching marshmallows.
- The only color that was not in my package of marshmallows was yellow so I used orange marshmallows in my yellow conversation heart hot chocolate bombs instead.
- For the white hearts, I used white mini dehydrated marshmallows.
White Hot Cocoa Mix
You can fill your white hot chocolate bombs with a store-bought white hot chocolate mix or you can make your own.
To make homemade white hot chocolate mix:
- Grate 4 ounces of white chocolate into a bowl using the fine holes on a cheese grater.
- Sift 1 1/4 cups powdered sugar and 1 1/2 cups powdered milk over top of the white chocolate.
- Stir together.
- Optional, stir in 1 teaspoon powdered vanilla. (I highly recommend it!)
Candy Mold & Paint Brush
- I found it easiest to cut my mold into 4 individual molds.
- If you do this, be sure to cut the edges of each smaller mold into curves so that you don’t cut yourself on the sharp edges.
- Use a clean and dried fine-tip paintbrush that has only been used for decorating food. Do not use a paintbrush that has been used for any other purpose.
Paint the red letters using candy melts.
- Dip your paintbrush into the bowl of melted red candy melts.
- Paint (or rather, dab) the chocolate into the indentations in the candy mold. You can watch the video to see exactly how this is done or you can also check out my “how to paint chocolate” tutorial for more details.
- Pop the mold into the freezer for about 2 minutes, just long enough for the candy to harden.
- That gives you enough time to paint the next heart and put it into the freezer when you take the first one out.
- Allow the molds to come to room temperature before filling them with colorful candy melts.
- NOTE: Red candy melts will streak and spot if you allow them to dry at room temperature, so I find it best to paint the letters in one mold then pop that mold in the freezer right away.
Paint colored candy melts into the heart mold.
- Melt pink, blue, purple, orange, yellow, green, or white candy melts to create the candy shell for your conversation heart hot chocolate bombs.
- Allow your candy melts to cool so that they do not feel hot to the touch. They should be warm but not hot. If they are too hot, the candy melts will melt the red candy letters.
- If your candy melts are too thick, stir in a pinch or two of Wilton’s EZ Thin to thin it out.
- Wilton’s EZ Thin are flakes of dried palm kernel oil that when melted help to thin out thick candy melts. They do not add any flavor and they allow the candy to harden properly.
- Just note that you don’t want the candy melts to be too thin, as they need to adhere to the side of the mold.
- Spoon 1 1/2 tablespoons of the colored candy coating into the bottom of the heart mold.
- Use a food-use-only paintbrush to brush the candy melts up the sides of the mold.
- Be sure you don’t brush too roughly across the bottom of the mold as that can also melt the red letters.
- Carefully flip the mold over to see if there are any air bubbles in the candy coating. If you see air bubbles pop them using your paintbrush.
- Immediately place the filled mold upside down on a parchment paper-lined pan and place in the freeze for 3-5 minutes just until hardened.
- Repeat, painting more chocolate hearts.
Fill your chocolate hearts.
- Sprinkle enough tiny marshmallows in each heart to cover the bottom.
- Then sprinkle about 2 1/2 teaspoons of white hot chocolate mix over the marshmallows.
- Use your finger or the back of a spoon to press the powdered hot cocoa mix into an even layer so that it is at least 1/8 of an inch from the top edge of the mold.
- Use a dry paintbrush to brush any powdered mix that is around the top edge of the chocolate.
Cover with more chocolate.
- Pipe more candy melts over the hot cocoa mix, making sure the edges are well filled in and the entire surface of the heart is covered.
- Gently tap the mold on the counter to remove any air bubbles.
- Smooth over any popped air bubbles and scrape any excess chocolate off the mold around the edge of the heart.
- Freeze for 3-5 minutes until hardened.
- Then carefully turn the mold over, holding your hand over the candy heart, and allow it to fall out of the mold.
- Let the candy heart warm to room temperature then use a sharp thin knife to shave off any excess chocolate around the edge.
- Let the mold warm to room temperature before painting it again.
NOTE about chilling chocolate or candy melts.
- The temperature will drop every time you open your freezer door, so as you go in and out of your freezer a lot it may take longer for your candy melts to harden.
- If you are using pure white chocolate you should harden the candies in the refrigerator, not the freezer.
- If you prefer you can fill your chocolate hearts with white chocolate ganache..
- Ganache is a creamy mixture of white chocolate and heavy whipping cream. It melts beautifully into a decadently creamy hot chocolate.
- You can see the recipe for filling them with ganache here – Conversation Heart Truffles.
- If you want to add marshmallows, just sprinkle them into the chocolate shell before pouring in the white chocolate ganache.
- If you are making these for adults, you can also fill them with boozy ganache.
Making hot chocolate using your bombs.
- Bring 6-8 ounces of milk to a simmer (just beginning to bubble) on your stove or in your microwave.
- Place a conversation heart hot chocolate bomb in a coffee mug.
- Pour the milk over top.
- Allow the chocolate to melt for a minute or two.
- Stir until completely melted.
Kids will especially love their cups of brightly colored white hot chocolate but I have to admit the adult in me loved it too.
