Since I love our sugar-free meringue cookies, which took me a few years to develop, having a go with those super chewy marshmallows was just a question of time. The moment I made meringue frosting, I instantly knew my next adventure. 

Because, whoever loves meringues, most definitely loves marshmallows as well. They are similar not only in the making but in taste buds as well. 

Do Sugar-Free Marshmallows Exist?

For years, I used to buy ready-made sugar-free keto marshmallows. Some of them I liked, but some not. 

Most store-bought marshmallows are covered with powdered sugar or chocolate, which I never liked. Do not let me start by mentioning the unnecessary ingredients they mostly contain. But I had no choice. 

Let me tell you, once you try this recipe, you are never going back. It tastes like the real thing. I am so glad we can now replace regular marshmallows made with sugar.

What Are Sugar-Free Marshmallows Made Of?

Sugar-free or keto marshmallows are extra easy to make with only a few ingredients needed.

Most marshmallows require a type of sugar or sugar sweetener, gelatin or Agar – Agar, and a bit of water.

Some recipes involve adding cream of tartar and flavors like mint, apple, lemon or banana.

Vanilla extract is also a perfect idea and can be added if you wish.

Instead of water, you can add some liquid from berries, which will color your marshmallows if you want to have them extra colorful.

What Sugar Substitute Is the Best for Keto Marshmallows Recipe?

For this recipe, I have, for the first time on my blog, used powdered sweetener Xylitol as a sweetener. 

Usually, I’m not particularly eager to use it as it is one of the sweeteners with a few carbohydrates.

But I always have it at home because it is the most accessible sugar sweetener in any shop.

The second reason is that Xylitol is the one sugar alcohol that is closest to the actual sugar taste.

And the third reason is that every time I try and develop recipes, I use them for the trials because it is the cheapest in the market. 

And this was the exact case. I have tried to make marshmallows first with Xylitol, as in most of my recipes, and it was so delicious that I have decided not to go further with trials and keep it as it is.

Can I use Allulose? 

For this recipe, you can also use Allulose, powdered monk fruit sweetener or liquid simple syrup, which I used for our meringue cookies.

I do not suggest using pure Erythritol, as it will give you a powerful cold aftertaste.

But if you do not have any other choice and have only Erythritol in the house and want to use it, then I would suggest mixing it a little bit with Stevia, which will balance the sweetness.

Are Keto Marshmallows Low In Calories?

Keto or low carb marshmallows are with almost no calories and are entirely fat-free. They are homemade marshmallows without any additional additives.

Nutritional information is calculated using Myfitnesspal and is all mentioned in the recipe card. 

They are a perfect snack if you have that sweet tooth.

Just be careful not to overeat on them, as they contain almost only sugar free sweeteners, which might cause tummy problems for some.

How To Make The Best Keto Marshmallows?

Once you follow our step-by-step instructions on how to make sugar-free marshmallows recipe, you will realize how easy, quick, and perfect it is to make them.

All you have to do is get your sweetener, a bit of gelatin, a bit of water, and mix it all together until the fluffiness evolves. 

Kitchen Gadgets you might need:

  • Stand Mixer
  • Saucepan
  • Square Dish
  • Cling Film or Plastic Wrap

Ingredients needed:

  • Grass-Fed No Sugar Gelatin
  • Sugar Sweetener
  • Water

*Exact measurements are listed in the recipe card below.

STEP-BY-STEP INSTRUCTIONS TO MAKE SUGAR FREE MARSHMALLOWS RECIPE

First Step: Ingredients

First of all, prepare all of your ingredients.

For the sugar sweetener, as I have already mentioned, I use Xylitol. The best is a powdered version, as this will readily dissolve in the water. 

If you do not have a powdered Xylitol but only a crystallized version, all you have to do is grind it inside the coffee grinder or magic bullet.

I have used gelatin sheets for the gelatin type as they are the easiest to work with, and no sugar added is involved.

And the third is a bit of water.

Second Step: Gelatin

If you are using gelatin sheets, place them into the water for a few minutes to soften.

If you use any other gelatin or Agar, please follow the instructions on the package.

Third Step: Melt and cook

Melt the sugar with water in a saucepan and place it on the stove. Let it boil for 2-3 minutes in a saucepan over medium heat, and add your softened gelatin sheets without the remaining water.

Make sure that the gelatin dissolves entirely.

Fourth Step: Pour and Mix

Once your hot syrup is prepared and the gelatin mixture is fully dissolved, pour everything into your bowl of a stand mixer with whisk attachment and turn the mixer on a high speed. At this stage, you can add the vanilla extract for extra flavor. 

Do not worry if the liquid is too hot. It will cool down while mixing.

This will take a few minutes at a high speed.

Mix until the liquid triples in size and the marshmallow fluff forms, which takes about 12 minutes.

Fifth Step: Whipped Marshmallow Fluff

Here you see the picture of how the marshmallow fluff is supposed to look.

In this step, you must work fast as the marshmallow mixture gets thick easily and quickly.

Sixth Step: Fill, smooth even and store

Have a square container or any container prepared in advance and covered with cling foil.

Pour the whole marshmallow fluff into the container and ensure everything is evenly smoothed. Try to use a rubber spatula.

Allow the mixture to sit on the kitchen counter to set for at least 8 hours or overnight.

TIPS AND TRICKS:

  • Thickens too quickly – No worries if your marshmallow fluff gets thick too fast. All you have to do is warm it up or place it into the microwave and back into the kitchen mixer to get the fluff ready again.
  • Grilling tip – If you want to use marshmallows for grilling, I suggest cutting them into the desired shape and letting them sit on the kitchen counter for a few hours so everything hardens up. That way, you will get a perfect brown fire effect with a still super smooth and soft marshmallow inside.
  • Reshape – There is no worry if you come up with shapes you do not like. All you have to do is place the marshmallows back into the microwave to warm them up and whip them in your kitchen machine again.
  • Avoid extra hardening – To avoid the marshmallows getting hard after cutting them, you can coat them with additional sugar sweetener.
  • Coloring – If you want to have colorful marshmallows, you must replace the water with the liquid you get from one of the berries.
  • Rice Krispies – Adding some sugar free keto rice krispies into the fluff before it melts, you can make rice krispy treats. 
  • S’mores – if you have graham crackers or chaffles on hand, make quick pieces of s’mores as well.

FREQUENTLY ASKED QUESTIONS AND ANSWERS

Can I Roast Homemade Marshmallows?

Once you make your marshmallows, you would have to let them harden a bit to roast them.

Once you cut them, they are already perfectly shaped, but for roasting, you would need a few more hours.

You have to let the squares harden a bit, place them onto a stick, and prepare for your barbecue night.

If you plan to roast those marshmallows, I would suggest making them the day before, cutting them in the morning into the desired shapes and letting them harden on the kitchen counter until the grilling starts.

How to Make Keto Marshmallow Fluff?

Making marshmallow fluff from this recipe is super easy. All you have to do is reduce the number of gelatin sheets to half and follow the same rule and steps below in the recipe.

You can then use your fluff for whatever you wish. Fill it up with some keto cookies, add the fluff into cannoli or eat it as it is.

How Do I Store Sugar-Free Marshmallows?

The store that marshmallow is the best to refrigerate as a whole piece covered with cling film. This will prevent the marshmallows from hardening from the outside and gives you the best result. The best is to consume them within 1 to 2 days. Cut them directly and enjoy them once ready to serve or eat.

Can I Dip Marshmallows in the Chocolate?

You can undoubtedly dip your marshmallows in the hot chocolate ganache or sprinkle it with chocolate. 

The best is to cut the marshmallows into your desired pieces and either let them harden for a few hours or place them into the freezer so they’re hard before dipping.

  1. Hey Zuzana,
    Thanks for the recipe! Have you ever tried this with Erythiol? I usually have problems after eating Xylitiol…

    Thanks in advance!

    Reply
    • Dear Veronika,

      I would not suggest pure Erythritol as it will give you a really strong aftertaste as Marshmallows are almost all sugar only. If Xylitol is making problems, try Allulose instead.

  2. WoooHoooo!!!! I tried FOUR different recipes with ALL different sugar alternatives. They all failed to deliver. (yes I followed all the directions meticulously!) I ordered xylitol as a last resort (instead of constantly having to buy VERY PETITE bags of sugar free marshmallows off Amazon) I googled a marshmallow recipe and yours came up. I had to make some conversions but I am so excited!!!!! At first I was worried about how little the recipe seemed to make. And then I read that solution tripled in size. As soon as the fluff started to form I knew it was a WINNER!!! 🙂 For those in the US, I used 1 packet of gelatin with 1/4 cup of COLD water, mixed it up and let it bloom. I also added a little vanilla. (I love vanilla!!!) But THANK YOU THANK YOU THANK YOU! This recipe is a winner!!!!

  3. Hi Zuzana,
    In the recipe it says to soak the gelatin in 40ml water, and then it says to combine the sweetener with water, but it doesn’t say how much water. Could you please tell me how much? Many thanks.

    Reply
    • Dear Helena,

      In the recipes you use 40 ml water, which you should combine with sweetener. Gelatine is something else. I have used gelatine sheets, which needs to be soaked in water (separate) and then added (only gelatine) into the mixture. If you are using gelatine powder or any other, please follow the instructions on the packets. Hope it clears it up a bit. Have a look at the video, where it is a bit more clear.
