Sugar Free Marshmallows (Keto Marshmallows) - Wholesome Yum (2024)

You need just a few ingredients to make these sweet, but surprisingly sugar free marshmallows! This low carb keto marshmallows recipe is made without corn syrup or sugar (of course), but the end result has the same taste and texture you’d get from the store-bought sugary kind… the key is this special sweetener.

I’ve had this sugar free marshmallows recipe for a few years now, but more recently, switching to using Besti powdered monk fruit really improved the texture.

I put these into little gift boxes with hot cocoa mix for my team last year, and it was such a fun project. (I don’t have the mix on the blog yet, but I do have keto hot chocolate you make right now with these. Or, do the classic thing and make s’mores with some keto graham crackers and keto chocolate squares.)

Anyway, it’s about time this post reflected the changes, so you can make the best keto marshmallows, too. 😉

The only annoying part about making sugar free marshmallows is that you have to beat them for a long time. It takes ten to fifteen minutes with a hand mixer! If you have a stand mixer, this is the time to take advantage of it.That way, you can do something else while it does its thing.

How To Make Sugar Free Marshmallows

Ready to learn how to make keto marshmallows? It’s super simple:

• Bloom gelatin. Sprinkle gelatin powder over water and whisk immediately. Let it sit for a while – it will turn into a gel.

• Make simple syrup. Heat water and Besti Powdered Monk Fruit Allulose Blend until sweetener dissolves. (This is the same process I use for keto simple syrup!) Remove from heat and stir in vanilla.

• Combine gelatin and syrup. Pour the hot syrup into the gelatin mixture, while whisking constantly.

• Whip marshmallow fluff. Using a hand mixer on high, beat the mixture until it doubles and looks like stiff egg white peaks. You should see streaks from the mixer.

TIP: You want to beat the marshmallows until stiff peaks form, but don’t overmix. Otherwise, it will be very difficult to spread the marshmallow creme into the pan, and the texture of the final product may be off.

• Spread and chill. Transfer to a parchment-lined pan, smooth with a spatula, and refrigerate for at least 8 hours or overnight, until set.

How To Cut The Keto Marshmallows

You can cut marshmallows into any shape you like, but typically you’d want cubes:

• Lift the edges of the parchment paper to remove from the pan.
• Use a large chef’s knife to make parallel cuts in one direction, 1 inch apart.
• Make parallel cuts in the opposite direction, to make a grid.
• Avoid a see-saw motion – use gentle downward or rocking motion instead.

Frequently Asked Questions

How many carbs in marshmallows?

Regular marshmallows have 6g net carbs each – and it’s all sugar! While 6 grams doesn’t sound like much, what are the chances you’d eat just one? It adds up quickly if you even have a few.

Fortunately, the carbs in these sugar free marshmallows are much lower – just 0.1g net carbs each!

Are marshmallows keto-friendly?

Regular marshmallows are pure sugar (and made with corn syrup!) – not keto friendly.

Fortunately, marshmallows on keto are possible. Just make your own homemade marshmallows without corn syrup using this recipe!

Are marshmallows sugar-free?

No, most marshmallows are usually made with a mix of granulated sugar and corn syrup to sweeten.Which is why we needed this easy low carb marshmallow recipe – it’s sugar-free!

Can you use a different sweetener?

When I first made this keto marshmallow recipe, my solution was to use a combination of powdered erythritol and vanilla stevia. The powdered erythritol is a finer consistency and takes some time to crystallize, so it worked okay, but they did crystallize over time.

When I re-tested these keto marshmallows with Besti Powdered Monk Fruit Allulose Blend, it turned out so much better. The texture is incredible!

This is why I only recommend Besti Powdered for this recipe now. Not only does it replace powdered sugar cup-for-cup, and when you make low carb marshmallows with it, the texture is almost identical to real ones.

Can you roast these healthy low carb marshmallows?

While this low carb marshmallow recipe has the flavor and texture of real marshmallows, they don’t roast well.

Fortunately, you can still make keto s’mores with them! The trick is to time the heat just right. You want to heat the marshmallows for just a few seconds, so that they just barely start to melt. Then, make the s’mores with them immediately, pressing down before they cool. Even though you don’t get the caramelized exterior, you do get that gooey texture!

Pair these sugar free marshmallows with my keto graham crackers for perfect keto s’mores!

Can you use sugar free marshmallows in recipes?

Usually, yes. You can absolutely use the keto marshmallow fluff in any recipes that call for fluff, and you can also make s’mores, provided that you don’t overheat the sugar free marshmallows, to avoid melting them.

Storage Instructions

Can you make these ahead?

Yes, the marshmallows store really well, so you can make them several days in advance.

How to store keto marshmallows

Store the marshmallows in the refrigerator for up to 5-7 days.

To store them, line an airtight container with parchment paper and arrange them in a single layer. If you need multiple layers, line with more paper between them, so that they don’t stick together.

Can you freeze sugar free marshmallows?

Yes, you can! For best results, arrange them in a single layer on a parchment lined baking sheet and place in the freezer. Once solid, you can transfer them to a freezer bag for storage.

To thaw, place them in the fridge overnight, or on the counter.
