Homemade Sugar-free Marshmallows

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.

Ways to Use Sugar Free Marshmallows

• Add to hot cocoa
• Make homemade s’mores
• Enjoy as a snack
• Cut into smaller pieces for dessert toppings, like on pudding or ice cream, or add to cookies or chocolate bark.

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.
