Sugar Free Marshmallows

Sometimes, you just want to feel like a kid again and eat a marshmallow!

However, you might not want all the sugar that comes with a traditional marshmallow. If you are looking for a healthier alternative, I’ve got it for you! These homemade low-carb and keto marshmallows are the perfect treat.

Now, I know what you might be thinking … the whole point of a marshmallow is the sugar. I promise you; you won’t even miss the real sugar.

An important tip when making this recipe, do not use straight Erythritol sweetener, like in the brand Swerve! Erythritol will recrystallize once cooled and will not produce the right texture. I recommend sticking with BochaSweet, a Monk Fruit blend, or Allulose for the best sweetener options.

Ingredients to make Sugar Free Marshmallows

With just a few ingredients and about 15 minutes of your time, you will have a perfectly fluffy marshmallow treat!

• 2 tbsp Unflavored gelatin powder
• 1 cup Water (warm, divided)
• 1 1/2 cups powdered BochaSweet (or powdered Monk Fruit)
• 1/4 tsp Sea salt
• 2 tsp Vanilla extract

Pro-Tip: Make sure you start making these sugar free marshmallows in advance of when you want to serve them. They don’t take long at all to actually make. But they do require 8 hours in the refrigerator to become firm and no longer sticky.

How to Make Sugar Free Marshmallows

Line an 8×8 (thicker marshmallows) or 9×13 (thinner marshmallows) baking pan with parchment paper. Set aside.

Pour 1/2 cup warm water into a large bowl, which will barely cover the bottom. Whisk in the gelatin and set aside.

Add remaining 1/2 cup warm water, powdered sweetener, and sea salt to a medium saucepan.

Cook over medium-low heat for a few minutes, stirring frequently, the sweetener dissolves and the liquid is heated, but not boiling. (Remove from heat as soon as you see bubbles forming along the edges)

Stir in the vanilla extract, then slowly pour into the large bowl with the gelatin, whisking continuously.

Beat the mixture with an electric hand mixer until the volume doubles and the mixture looks very fluffy, like stiff egg white peaks (15 minutes, minimum).

Transfer the marshmallow mixture into the parchment-lined baking pan.

Chill in the refrigerator for at least 8 hours. (It should be firm and no longer sticky).

Gently, cut into squares and enjoy!

Are Marshmallows Keto-Friendly?

Traditional marshmallows are pure sugar (AND made with corn syrup!) … so no, they are definitely not keto-friendly.

Fortunately, thanks to this recipe, enjoying a marshmallow while sticking to a ketogenic lifestyle is possible!

Can you use sugar-free marshmallows in recipes?

Yes! You can absolutely use the sugar free marshmallow in other recipes. Easiest example, you can make fluff!

How to store Keto Marshmallows

Store the marshmallows in the refrigerator for about 4-6 days.

To store them, I recommend lining an air-tight container with parchment paper and arrange them in a single layer. If you need to layer your marshmallows, put parchment paper in between the layers so they don’t stick together.

Can you freeze Sugar Free Marshmallows

Yes, absolutely! For the best freezing results, prepare them the same way you would for the fridge ie: an air-tight container and parchment paper.

To thaw, place them in the refrigerator overnight.

How to Enjoy Sugar Free Marshmallows:

These marshmallows are perfect for eating by themselves or using them in other recipes like dunking in low carb/keto hot cocoa or low carb/keto rice krispy treats.

However, I don’t recommend roasting these over a fire. Keto marshmallows do not roast well over an open fire like a traditional marshmallow.

So, if you are looking to make s’mores, grab a culinary blow torch. With that, you will get a nice melt/roast for your s’mores … and with less effort!

Other Recipe Tips and Tricks

• With an electric hand-mixer, it takes about 15 minutes for the mixture to whip up to peaks, so if you have a stand-mixer, I highly recommend using that.
• For thicker marshmallows, use an 8×8 baking dish, for thinner marshmallows, use a 9×13 baking dish
• These won’t roast over the fire the same as regular marshmallows, but if you have a culinary blow torch, you can heat them until slightly melty when making smores.
