These sugar free marshmallows are light, fluffy, and easy to make. They’re a great alternative to store-bought marshmallows when you want a sweet treat without all the sugar.

They’re perfect for hot cocoa, snacking, or homemade s’mores—and you can adjust the sweetener to fit your dietary needs.

If you’ve ever wondered whether you can make marshmallows without sugar, the answer is yes—and they’re surprisingly delicious.

Making marshmallows at home is also a lot of fun. It’s amazing to watch a simple mixture transform into thick, glossy fluff and then set into soft, pillowy squares that taste even better than the packaged kind.

I love fun treats, but store-bought marshmallows often contain a lot of sugar and unnecessary additives. Making them at home gives you full control over the ingredients.

We used to make these marshmallows with sugar, but now that we've gone low-carb, those days are over. But you can substitute the low-carb sweetener with a regular one if you'd like.

I love making these marshmallows with our sons. What fun to see water, sweetener, and gelatin turn into white fluffiness in a bowl, and then seeing them turn into marshmallows that tasted much better than anything I'd ever bought in a bag.

Why Make Homemade Marshmallows

  • Control the ingredients: Skip additives, dyes, and sweeteners you’d rather avoid.
  • Lower sugar option: A great alternative to traditional marshmallows when you want a sweet treat without all the sugar.
  • Flexible for special diets: Works for low-carb, keto, paleo, and more depending on the sweetener you choose.
  • Fun to make: Watching the mixture whip into fluffy marshmallow is part of the magic.
  • Perfect for treats: Great for hot cocoa, s’mores, or just enjoying on their own.
  • Save Money: Sugar-free marshmallows cost a small fortune. Making them at home is so much less expensive.

We’ve even used these to make homemade s’mores (using homemade chocolate bars), and they were a huge hit with an organic skincare expert and friend who was visiting from Australia. She'd never had s'mores before!

Why This Recipe Works

  • Uses allulose for proper structure: Helps create a soft, fluffy texture similar to traditional marshmallows
  • No egg whites needed: Keeps the recipe simple and more allergy-friendly
  • Balanced liquid ratio: Allows the marshmallows to whip up thick and set properly
  • Whips to the right consistency: Creating that classic glossy, stable marshmallow texture

Best Sweetener for Sugar Free Marshmallows

Allulose works best for making sugar free marshmallows because it creates a soft, fluffy texture and allows them to melt and brown more like traditional marshmallows.

If you prefer a sweeter result, you can use an allulose blend (such as allulose combined with monk fruit or erythritol), but the texture may be slightly firmer.

Erythritol alone is not recommended, as it can result in a firmer, less smooth texture.

Frequently Asked Questions

Will These Sugar Free Marshmallows Roast?

Yes—if you make them with allulose, they can actually roast and brown nicely. They do tend to soften and brown more quickly than regular marshmallows, so keep a close eye on them.

Most other low-carb sweeteners will not roast the same way, though they can still get soft and gooey.

Can You Make Marshmallow Shapes?

Yes! These marshmallows work well in silicone molds.

Lightly grease the molds, then spoon or pipe the marshmallow mixture in. Let them set fully before removing.

Can You Use Other Sweeteners?

You can experiment with different sweeteners, but the results will vary.

Allulose typically gives the best texture and roasting performance. Erythritol alone does not work well, so it’s best to start with the sweetener recommended in the recipe.

What Kind of Gelatin Is Best?

Look for a high-quality, grass-fed gelatin if possible. This helps give the marshmallows the best texture, structure, and nutrition.

Substitutions for Special Diets

  • Vegan option: Agar may work in place of gelatin, but I haven’t personally tested this version, so results may vary.
  • Sweetener options: Different sweeteners can work, but texture and sweetness level will change. See recipe notes for best results.
  • Glycerin substitution: Another sweetener may work in place of glycerin depending on the version, but some experimentation may be needed.

Flavor and Coating Variations

It’s easy to customize these sugar free marshmallows with different flavors and/or coatings.

Cocoa Marshmallows

For a light chocolate flavor, add 1–2 tablespoons cocoa powder when mixing in the vanilla. You can also dust the finished marshmallows with cocoa powder for a richer chocolate coating.

Coconut Marshmallows

Roll or sprinkle the finished marshmallows with unsweetened shredded or toasted coconut for extra texture and flavor. This works especially well for a slightly firmer, less sticky exterior.

Berry Marshmallows

For a naturally flavored option, grind freeze-dried berries (like strawberries, raspberries, or blueberries) into a fine powder using a spice grinder. Either mix the powder into the marshmallow mixture at the end of whipping or dust it over the finished marshmallows for a light fruit flavor and a nice burst of natural color.

Start with a small amount and adjust to taste, as freeze-dried fruit powders are concentrated.

Powdered Sweetener Coating

Lightly dust the marshmallows with powdered low-carb sweetener to prevent sticking and give them a classic look.

Mixed Coatings

Try combining coatings for variety—some plain, some cocoa-dusted, and some rolled in coconut. This is a fun option for serving or gifting.

Prep Time: 20 minutes
Cook Time: 10 minutes
Total Time: 30 minutes
Servings: 9 dozen of marshmallows approximately
Calories: 8kcal

Ingredients

  • 2 tablespoons gelatin
  • 1/2 cup cold water
  • 1 1/2 cups allulose
  • 1/2 cup hot water
  • 2 teaspoons vanilla extract

Instructions

  • Add the cold water to a large mixing bowl. Sprinkle the gelatin evenly over the top and let it sit for 5–10 minutes to bloom.
  • In a small saucepan, combine the allulose and hot water. Heat over medium heat, stirring until fully dissolved. Continue heating until the mixture reaches 240–245°F (soft ball stage).
  • With the mixer running on low speed, slowly and carefully pour the hot mixture into the bloomed gelatin.
  • Increase speed to high and beat for 8–12 minutes, until thick, glossy, and fluffy. The mixture should hold its shape and form soft peaks.
  • Mix in the vanilla extract (and salt, if using).
  • Beat on high until the mixture form stiff peaks (almost like beaten egg whites).
  • Pour the mixture into a lightly greased or parchment-lined 8×8 pan, or into molds. Smooth the top quickly, as it will begin setting fast.
  • Allow the marshmallows to set at room temperature for several hours, or until firm. You can refrigerate to speed this up, but avoid freezing.
  • Cut into squares using a greased knife. If needed, lightly dust with powdered sweetener or starch to reduce stickiness. Dusting with cocoa powder will do the same and will add nice flavor as well.
  • Store in an airtight container and try to keep your kiddos out of them!

Notes

  • Use allulose for best results: It creates the softest texture and allows the marshmallows to melt and brown more like traditional ones.
  • Whip until thick and glossy: The mixture should hold its shape before transferring to the pan.
  • Work quickly: Marshmallow mixture sets fast once whipped, so pour it into the pan or molds right away.
  • Grease well: Lightly oil your pan, spatula, and utensils to prevent sticking.
  • Let fully set: Allow to set in mold or pan for several hours for best texture and clean cutting.

Tips for Perfect Sugar Free Marshmallows

  • Use the right sweetener: Allulose gives the best texture and allows the marshmallows to brown when roasted. Other sweeteners may not perform the same.
  • Whip long enough: The mixture should become thick, glossy, and hold its shape. This is key for that classic fluffy texture.
  • Work quickly: Once whipped, the mixture sets fast, so transfer it to your pan or molds right away.
  • Grease everything well: Marshmallow mixture is very sticky—lightly oil your pan, spatula, and even your hands if needed.
  • Let them fully set: Give the marshmallows enough time to firm up before cutting for clean edges.

  1. Hi!

    In your post where it says you’ve read about people using 1:1 sweetener and water does that mean I should be okay omitting the glycerine? I read agar Flakes can be substituted 1:1 w gelatin but is 1 Tbs gelatin to 1 tsp agar powder. or 1 tsp agar powder for each 1 cup of water. That’s why I was wondering if I could omit the glycerine I’m not sure if I should ad a 1/2 tsp of agar powder for it since it’s a thick syrupy liquid. Do you think date sugar would work for the granular sugar or does it need to be able to dissolve? If it does I was going to try maple sugar instead. If I need to add the glycerin do you think date paste would work? If not I’d try maple syrup. Anxious to hear what your thoughts are!

    Kellie?

    1. Hi there. First of all, sorry for the delay in responding. I have been inundated here and also lost access to older comments for awhile. I am a little confused by your comment. Are you wanting to use agar and no gelatin and then wondering about sweeteners?

      For the agar, I am reading that some have had success, but others have not. I am still not sure why–haven’t had time to experiment. I think you should be able to omit the glycerine, but again, not promising it will work out.

      As for the date sugar–you are saying that it wouldn’t dissolve when heated in water? I didn’t know that. I would think it would when heated but I have never experimented with that either for dissolving in water or for this recipe. I would think any sweetener should work but you will of course have varying results. I would love to hear back about what you tried and how it worked!

  2. Is it supposed to be dense? mine came out rather airy and not marshmallow textured at all. Beat it too long?

    1. Yes, they can be. They might act a bit differently but I have used them for making krispie treats and they have worked great. They just might not roast well depending on the sweetener that you use.

    1. Hi there. Yes, it can do that so people can make their own decisions about how to use it or not. I have friends with dogs who don’t and others who are just very careful. Other foods can kill animals as well like raisins. It’s important to be aware – thanks for reading!

  3. i tried one sugar free recipe, not yours and it was so overly sweet i couldnt eat it. i bought the powdered sugar free by sweve, i also have xylitol. i love love marshmallows what do you suggest. the powdered orr the granular xylitol. i have vanilla liquid stevia as well. should i use less sugar?

      1. What sweetener did you use? However, marshmallows are very sweet b/c they are almost completely made up of sugar / sweetener.

        1. swerve confectionary just as your recipe stated. i love marshmellows but didnt want the sugar, any suggestions?

          1. Hi Susan, I’m not sure what to suggest as the main ingredient in any marshmallow is a sweetener. Would honey work for you?

  4. i cut out sugar from my diet, and chewy sweet is what I am in need of! I’m also not a fan of gelatin, and so I’m using ball”s no-sugar needed pectin, and agave as my liquid sweeter (my doc approved). I will report back!

  5. Very nice recept. i want to try it but i dont have any liquid sweetener. If i use only erythrol do i understand right i have to take 1 1/2 cup plus 3/4 cup and thats all of sweeteners

    1. Thanks! So really you would want to try 2 cups erythritol, but another reader said using just erythritol didn’t work out well. I haven’t tried it but I see other erythritol only recipes so not sure what to say. Hope it works out!

  6. Hi there!

    These look amazing! I’ve been looking for a sugar free marshmallow recipe and I have a party this weekend I would love to try these with!

    Quick question. You have a lot of variations listed in your ingredients. Can you tell me the best version you’ve tried thus far? I have liquid stevia, granulated and powdered xylitol and erythritol sweeteners, and vegetable glycerin. Would love to know what combination works best for you.

    Thanks!

    Amanda

    1. Hi Amanda. We really like the xylitol with veg glycerine one. I haven’t tried all of the possible options but that one works well. Sorry for the late response and hope you like them!
