Dark Chocolate Marshmallows or…. Edible Coal for Stockings!

I’ve been chasing the perfect chocolate marshmallow for what feels like forever (4 years, but still!); by adding cocoa in varying amounts (they either didn’t taste very chocolaty or they were dry and lost their bounce) or folding in melted chocolate (made them dense). And after a while, I just gave up and said it couldn’t be done. 

But last month I had this idea to make an ‘edible coal’ for Christmas stockings by using black cocoa and the urge came over me to try again. A little digging and researching took me to try out blooming the cocoa – and it worked, like a perfect charm.  Blooming the cocoa not only draws out the cocoa’s flavor but the paste balances out the cocoa so that it won’t dry out the marshmallow. The marshmallows are bouncy and light, and actually taste like chocolate! 

Ingredients for Dark Chocolate Marshmallows 

Cocoa: Use a very good quality brand. I used black cocoa in mine for that ‘coal’ look but any dutch process cocoa will work. 

Gelatin: I use the knox powdered gelatin packets, four or one box for this recipe. They clock in at 1 oz total. 

Sugar: Fine granulated, 

Corn syrup: Use light, organic or non organic. You can also use honey but if you do use a very dip pot as it will boil up, keep in mind also that the flavor may come through the chocolate depending on how strong tasting your honey is. 

Salt: Fine sea salt. Use less if using table salt as table salt is saltier. 

Vanilla: Pure vanilla extract. If you’re feeling fancy scrape up a vanilla bean but since chocolate is our goal it’s probably not necessary. 

Powdered sugar: I’m going to stress this one very hard, use organic powdered sugar made with tapioca starch (NOT cornstarch). If you’ve made mallows before you probably used a mix of powdered sugar and more cornstarch and it’s not very nice. Cornstarch doesn’t melt on the tongue and your mallows will taste chalky.

FAQ on Dark Chocolate Marshmallows

Can I halve this chocolate marshmallow recipe? 

Just use half of all the ingredients listed. You can set them into a loaf pan if you still want tall mallows. 

Do these chocolate marshmallows travel well? 

Exceptionally well actually, simply put them in an airtight container so they don’t dry out.  

Tips to make the most perfect homemade chocolate marshmallows 

  • Use a scale: for better accuracy in measuring the sugar and syrup. 
  • Use a candy thermometer: This one is necessary, you want the mallows to reach 250 no less because we want a mallow that can take the cocoa paste we’re adding in later so we need to ‘candy’ the sugar right. 
  • Use good quality cocoa: This is your main flavor ingredient so choose well! 
  • Whip as long as necessary: Don’t rush this, the mallow fluff needs to whip for at least 10 minutes, until it’s very stringy. If you whip less the marshmallows will be kind of wet and dense. 

Recipe for Black Cocoa Hot Chocolate 

If you’ve dug around my marshmallow corner on this site you may have run into a recipe for ‘hot cocoa’ made with caramelized white chocolate. Couldn’t help myself this year either, it definitely seemed like the year of the black cocoa and so I came up with a recipe for black cocoa hot cocoa, here’s how to make enough to serve 2-3 people: 

You’ll need: 65g milk chocolate, 2 tablespoons black cocoa, a pinch of salt, 1 teaspoon vanilla, and 2 ¼ cups whole milk. Pour all the ingredients into a pot and cook on medium low, whisking as needed until the chocolate is fully melted and the cocoa is all dissolved.

Servings 40 marshmallows

Equipment

  • stand mixer

Ingredients
  

  • 4 packets of gelatin powder 28g
  • cup cool water
  • 1 teaspoon fine sea salt
  • ¼ cup boiling water
  • ¼ cup black or dutch process cocoa or a mix of both
  • 2 teaspoons pure vanilla extract
  • cup cool water
  • 450 g sugar
  • 185 g light corn syrup
  • ¾ cup organic powdered sugar made with tapioca starch
  • cup black or dutch cocoa

Instructions
 

  • Grease a 13×9” or 9×9” square baking pan with canola oil (or any flavorless oil). Whisk together the water, salt, and gelatin in the bowl of a stand mixer and set aside to firm up.
  • In another bowl, whisk together the boiling water, cocoa and vanilla until it’s smooth and creamy, like a ganache. Set aside.
  • Weigh the sugar and corn syrup in a deep pot and add the water and stir. Clip a candy thermometer to the pot and set it over medium heat. Cook until the temperature reaches 250 F (it really should get to 250, not 245!).
  • Begin whisking the gelatin mixture on low and slowly pour in the hot sugar with the mixer on. Turn the speed to medium high and add the chocolate mixture. Let whip for about 10 minutes, until the marshmallow fluff gets stringy and begins to pull away from the bowl. Transfer to the prepared cake pan and smooth into one layer. Cover with foil and leave overnight at room temperature or set in the fridge for 3 hours to firm up.
  • Whisk together the powdered sugar and cocoa into a large bowl and dust the countertop with some of it. Transfer the marshmallow to the counter and using an oiled chef’s knife, slice into cubes. Toss the cubes in the bowl so you can coat all the edges.
  • Store marshmallows at room temperature in an airtight container. They’ll last about 3 weeks.

    I haven’t made these as standalone marshmallows yet but I plan to. I made a half recipe and put it on top of the s’mores brownie recipe she also has and it was fantastic. I made a fluffernutter sandwich with the mallow fluff remnants in the mixing bowl after I topped the brownies. And if you like chocolate and pb together I highly recommend. I might have to top pb blondies with these marshmallow next.

    This was the second marshmallow recipe from your website I have used, after having good luck with the brown sugar and chocolate marshmallows. I appreciate the clear instructions and got compliments from friends about how well these pair with hot chocolate in the middle of winter.

    Fantastic recipe! So far we have enjoyed these as tasty snacks and on hot coffee. I ended up having to whip them for about fifteen minutes in our kitchen conditions but that worked just fine. Also, the cocoa I got was so black that I chose to toss them in regular dark cocoa powder to make them look a little more chocolaty. Very delicious, we love all of your marshmallow recipes!

    So… this is my favorite marshmallows recipe! I was actually going to make the brown sugar chocolate marshmallow recipe which I had made before, but this recipe came up! I love dark chocolate, so I just had to try it! And man it tastes so so good! So much chocolate taste and I used a really cheap cocoa powder (Hershey’s Special Dark), since that’s all I have. I can’t imagine how much chocolatier this would taste with better quality cocoa powder! I will be making this for the third time this month. The first two batches I gave out for the holidays. The third, I naught give more out… or just eat them all myself.

    Thank you Sam once again for making yumminess we can all follow!
    It is so easy to make and smells so chocolatey when I open up my container I store these in.

    On another note, I added melted dark chocolate and swirled it after I poured the marshmallow onto the pan to add even more chocolate flavor and crunch and I’ll do this from now on!

  • Just made the brown sugar chocolate mallows yesterday and looks like I’ll be pulling out the mixer again today to make these! One question…in this step “Begin whisking the gelatin mixture on low and slowly pour in the hot sugar with the mixer on.” should we heat the gelatin mixture back up so it’s liquid, like we do in the brown sugar mallow recipe?

    Your marshmallow recipes are the only ones I’ve had success with…thank you for all the effort developing them!
