I love how these marshmallows use only a handful of ingredients while still creating a texture that feels just like traditional marshmallows. They are sweet, pillowy, and surprisingly easy to make at home.
This recipe is also great for anyone looking for a lower-carb dessert option. I can use these marshmallows for s’mores, hot cocoa, or dessert toppings without sacrificing flavor or texture.
Ingredients
(Note: All ingredient amounts are listed in the recipe card below.)
1 cup water
2 tbsp gelatin powder unflavored
1 cup Allulose powdered
1 tbsp vanilla extract
Directions
Line an 8×8-inch pan with parchment paper and set it aside.
In a small bowl, combine ½ cup of water with the gelatin powder. I whisk it gently and let it sit for about 10 minutes so the gelatin can bloom.
In a small saucepan over medium heat, combine the remaining ½ cup of water, powdered allulose, and a pinch of salt. I stir constantly and bring the mixture to a gentle simmer for about 5 minutes until the sweetener fully dissolves.
Add the bloomed gelatin to the bowl of a stand mixer or use a hand mixer. With the mixer on low speed, slowly pour in the hot sweetener mixture.
Increase the mixer speed and beat the mixture for about 10–12 minutes until it becomes thick, fluffy, and forms stiff peaks similar to whipped egg whites.
Quickly pour the marshmallow mixture into the prepared pan and smooth the top with a rubber spatula. I work fast because the mixture begins setting quickly.
Refrigerate the pan for at least 6 hours or until the marshmallows are fully firm.
Once set, cut the marshmallows into squares with a sharp knife. I dust each piece lightly with keto powdered sweetener to prevent sticking.
Servings and Timing
Yield: 16 servings
Prep Time: 20 minutes
Cook Time: 5 minutes
Chill Time: 6 hours
Total Time: 6 hours 25 minutes
Variations
I sometimes add peppermint extract instead of vanilla for a festive flavor. When I want chocolate marshmallows, I mix in a little unsweetened cocoa powder during whipping.
For colorful marshmallows, I add a few drops of natural food coloring before whipping the mixture. I also enjoy coating the finished marshmallows with shredded coconut or cinnamon for extra texture and flavor.
If I want mini marshmallows for hot chocolate, I cut them into smaller cubes after chilling.
Storage/Reheating
I store the marshmallows in an airtight container at room temperature for up to 1 week. I usually place parchment paper between layers to prevent sticking.
For longer storage, I refrigerate them in a sealed container. I do not recommend freezing because the texture can become sticky and less fluffy after thawing.
If the marshmallows begin sticking together, I lightly dust them again with powdered keto sweetener before serving.
FAQs
Can I use a different sweetener instead of allulose?
I find allulose works best for texture, but some keto sweeteners can also work with slight texture differences.
Why do I need to bloom the gelatin?
Blooming helps the gelatin absorb water evenly so the marshmallows become smooth and fluffy.
Can I make these without a stand mixer?
Yes, I sometimes use a hand mixer, although it takes a little more effort and time.
How do I know when the mixture is whipped enough?
I beat it until stiff peaks form and the mixture becomes thick, glossy, and fluffy.
Can I toast these marshmallows?
Yes, I lightly toast them just like regular marshmallows for s’mores or toppings.
Why are my marshmallows sticky?
They can become sticky if not fully chilled or if they need more powdered sweetener coating.
Can I flavor the marshmallows differently?
Yes, I like experimenting with peppermint, almond, coconut, or citrus extracts.
Do these marshmallows need refrigeration?
I can store them at room temperature for short periods, but refrigeration helps them stay firmer longer.
Can I use these in hot chocolate?
Yes, they melt beautifully into warm drinks and taste delicious in hot cocoa.
How long do homemade sugar-free marshmallows last?
I usually enjoy them within one week for the best texture and flavor.
Conclusion
These sugar-free marshmallows are soft, fluffy, and packed with classic marshmallow flavor while staying completely low in sugar. I love how easy they are to make with simple ingredients and how versatile they become for desserts, drinks, and snacks. Whether I roast them over a fire or drop them into hot chocolate, they always feel like a fun homemade treat with a perfectly airy texture.
These sugar-free marshmallows are soft, fluffy, and perfectly sweet without using traditional sugar. They are light, airy, and ideal for hot chocolate, roasting, desserts, or low-carb snacking.
