Are you ready for this guys? These taste almost like real marshmallows! They are light and fluffy but there's no sugar they won't be as chewy as the real deal. They're still quite close though!

Initially, I thought these won't be suitable for roasting. Regular marshmallows contain 3 basic ingredients: sugar, gelatine and water. When it comes to roasting, sugar is, unfortunately, the most important ingredient. It's sugar that makes marshmallows caramelise. If there is no sugar, there is nothing to caramelise, right?

Luckily there are a few sweeteners that work: erythritol, Swerve, tagatose and xylitol (allulose also works well and there is no caramelisation!).

Unlike other low-carb recipes that I've tried, these Healthy Low-Carb Marshmallows can be roasted. They work well as topping in pies, muffins or even in my Low-Carb Candied "Yams" - perfect for Thanksgiving! If you want to roast them on a stick, remember to dry them well by leaving them at room temperature uncovered overnight.

Gelatin Substitutions

If you use gelatin sheets, you should use 3-4 sheets for every envelope or tablespoon of gelatin powder (3-inches by 5-inches gelatin sheets/leaves). Based on feedback, Agar powder (a vegetarian substitute) does not work in this recipe.

How to Make Raw Eggs Safe to Consume

If a recipe calls for raw eggs and you are concerned about the potential risk of Salmonella, you can make it safe by using pasteurized eggs. To pasteurize eggs at home, simply pour enough water in a saucepan to cover the eggs. Heat to about 60 °C/ 140 °F. Using a spoon, slowly place the eggs into the saucepan. Keep the eggs in the water for about 3 minutes. This should be enough to pasteurize the eggs and kill any potential bacteria. Let the eggs cool down and store in the fridge for 6-8 weeks.

Ingredients (makes about 36 marshmallows)

Optional toppings:


  1. Line a pan with parchment paper. Sprinkle with a layer of coconut flour. I used 8 x 8 inch/ 20 x 20 cm dish. Fluffy Low-Carb Marshmallows
  2. Place the gelatin into a pot and add 1/4 cup of cold water. Tilt the pot to allow the water everywhere. The gelatin will bloom and become firm in just a couple of minutes.

  3. Separate the egg whites from the egg yolks. (You will only need the egg whites in this recipe but you can store the egg yolks in the fridge and use them to make your own mayonnaise or low-carb lemon curd.)

  4. Cut the vanilla bean lenghtwise and scrape the tiny seeds out. Fluffy Low-Carb Marshmallows
  5. Using an electric mixer, start beating the egg whites. Slowly add the cream of tartar, powdered Erythritol, vanilla seeds and salt. Fluffy Low-Carb Marshmallows
  6. Keep beating for a minute or two until it becomes thick and creates soft peaks.

  7. Add the remaining boiling water to the pot with the gelatin and stir until dissolved. If you still see some lumps, briefly boil over a low heat and stir well until fully dissolved. Add stevia and combine well. Fluffy Low-Carb Marshmallows
  8. Turn the mixer to medium speed and very slowly pour a steady stream of gelatin into the egg whites. After you pour all the gelatin, turn the mixer to high and continue beating until it becomes thick and creamy (3-5 minutes). Fluffy Low-Carb Marshmallows
  9. Turn off the mixer and quickly transfer the marshmallow cream into the pan lined with parchment paper and sprinkled with fine coconut flour. Fluffy Low-Carb Marshmallows
  10. Spread evenly all over the pan. Fluffy Low-Carb Marshmallows
  11. Sprinkle more coconut flour on top and pat level if needed. If you are not using any coating, grease your hands with coconut oil and pat smooth. Fluffy Low-Carb Marshmallows
  12. Place in the fridge for 2-3 hours or overnight until the marshmallow cream is fully set. When done, remove the pan and peel the parchment paper off. Cut into cubes, 6 by 6 to create 36 marshmallows.
    Fluffy Low-Carb Marshmallows
  13. If you make plain marshmallows with no topping, place on a plate and cover with a towel for a few hours. Then, store them in the fridge in an airtight container to avoid drying. Fluffy Low-Carb Marshmallows
  14. Melt the chocolate in a water bath. Dip a lolly stick into the chocolate and then add the marshmallow. It's best to use a water bath for melting chocolate, especially if it's high in cacao content. Melting chocolate directly could result in burning. Fluffy Low-Carb Marshmallows
  15. Dip each marshmallow into the melted chocolate and keep turning until the chocolate stops dripping. Fluffy Low-Carb Marshmallows
  16. Alternatively, you can skip the lolly stick and just dip the marshmallows in chocolate.
    Fluffy Low-Carb Marshmallows
  17. Sprinkle each marshmallow with shredded coconut and place on parchment paper until the chocolate hardens.
    Fluffy Low-Carb Marshmallows
  18. Let them dry at room temperature (they'd get sweaty in a container). After they dry you can place them in a container lined with paper towel and store them sealed in the fridge. Fluffy Low-Carb Marshmallows
    These low-carb marshmallows make great Holiday gifts and are totally torchable! Fluffy Low-Carb Marshmallows

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Can I omit erythritol and stevia? I dont'use any type of sweetner but I would like tra this recipe

I think you can easily omit the stevia but I'm not sure I'd omit the Erythritol as marshmallows are pretty much all about being sweet. You can try but I can't guarantee it will taste of anything. I think it may also impact the texture. Just in case, here's a proper marshmallow recipe with Allulose: No Fail Fluffy Keto Marshmallows
Sweetener-free treats are here (some contain sweetener but it can be omitted): Sweetener-Free Keto Desserts

Can these be stored frozen? We’re going camping in a few weeks and I was hoping to make these ahead of time and freeze.

I have never frozen these but I think that shouldn't be an issue as there isn't much liquid in these. I can't guarantee they will be ok though - let me know if you try it. I'll be sharing marshmallows that don't use any egg whites in the next few days - you may want to make those instead as I think they will freeze better.

This recipe looks good. I 'm going to have to try it.

You'll love it 😊

Hi there!! So I know this recipe is pretty old, and I'm not sure if you still do this (hope so!!). So, first, monk fruit is big now. It's mixed with eryth-blah-blah (I don't have it in front of me, and have a hard time pronouncing it 😂) But, have you tried it with this? Second, does it actually TASTE like marshmallow? Because I have seen marshmallow extract. Just curious. It's 9:58pm, and I'm about to go to the store to get some gelatin. 😁 I made some keto custard earlier, so I have a 6 whites what do i do with the other 3? Hmmmm...***rubbing chin thoughtfully***

Hi Brianne, you can definitely use monk friot based sweetener or even powdered tagatose or allulose - all of these options will work in this recipe 😊
These taste like something between a meringue and a marshmallow - not exactly like a marshmallow but it's pleasant and not too sweet.

Hello Martina,
I am on the hunt for a Keto Marshmallow (pieces) that I can add to a chocolate nut roll, would these work or would they melt into warm chocolate?
Thank You So very much.
Colleen Love

You can dip them in warm chocolate but it's better if it's not hot. I used almost room temperature chocolate just to be sure 😊 On the other hand they did work well in this recipe: Low-Carb Candied Yams with Marshmallows

This is my first recipe comment EVER, but I rely on them so heavily while exploring my new keto diet that I thought I should share too.
These turned out amazing! I was almost embarrassed to even look for Keto marshmallows— like that would even be a thing?! But fall s’mores had me on the hunt. I compared several recipes, but decided on this one because of the simple ingredients. Im not even a fan of marshmallows outside of their necessity in s’mores, but I snack on 1or 2 of these every night for my sweet tooth. Great taste and texture!
I may have relied too heavily on the photos because the changes I made were simply due to mine not looking like yours, but they still turned out delicious. I had to keep adding water into the gelatin, a tablespoon at a time, because the water called for in the ingredient list was not soaking up all the powder. I just stopped adding water when it looked like the photos showed. I also ended up almost doubling the powdered swerve because my batch was looking much more off-white/yellow than yours in the photos. I’m glad I did! Still the perfect amount sweetness.
Thank you!

Hi Heather, thank you so much for your lovely feedback! Oh don't ever feel embarrassed, I don't think there is a recipe I haven't looked for after going keto! 😊

Is the carb count listed for the ENTIRE recipe or for each individual marshmallow?

It's per marshmallow including the chocolate topping.

This looks amazing. I must be missing something really do I print recipe out? Please excuse me as this is my first time to your blog. Thank you in advance. =)

Thank you so much! You are right, for some reason the print option is missing in this recipe. I'll have a look and fix it as soon as I can. Thank you for reporting this!

Just wanted to say that I made these last weekend and brought them with us camping and these Roast wonderfully! While they didn't get the brown crust a "normal" marshmallow they became ooey and gooey and delish! Also used them to make Smores and again they work perfectly! Thank you so much!

Thank you so much Amy, I'm glad to hear that they were great for roasting! 😊

Try with Allulose! It browns & caramalizes like regular sugar. You can even make brittle with it, but has only 70% of cane sugar's sweetness, so more might be needed.

Agreed! Since Allulose became available I made a recipe with it: No Fail Fluffy Keto Marshmallows

I had a ton of leftover egg whites from making several batches of frozen custard so my search to use them up brought me here. This recipe is so much fun-- the texture alone is addictive! I didn't have cream of tartar so I subbed ACV as you suggested. I also didn't have swerve so I just skipped that. Otherwise I followed your instructions exactly and these came out perfect. Thank you for sharing your genius!

Thank you so much for your lovely feedback!

Hi Martina-
Is there a reason you chose not to make a very hot syrup (I think something in the range of 240-245 F is usual) to add to the egg whites?  I don't have vast amounts of experience with erythritol but I believe it stands up to heating (even if it doesn't behave in all the ways that sugar would).   Using a hot syrup would deal with the issue of cooking the egg white, I think.  (I do acknowledge that you have included instructions for pasteurizing the eggs.)   Would you be willing to share the thinking that led to your technique?

Hi Alex, I haven't tried that but I think there would be too much moisture from the syrup. Also, erythritol does not behave like sugar when mixed with water and heated. It may work but you may need to add more gelatine.

HI - could this receipe be used for pecan log rolls?  If so, how would you suggest to roll in the pecans?  I am not much of a cook but would love to try these.  It looks like the cream is way too soft to immediately put the pecans on them but then way too hard after setting in the fridge.  Any ideas?

That's a great suggestion but I'm not sure how that will work. It may be better to use a more "traditional" approach, I don't think you will be able to roll it. Here's a recipe you may like: Keto Nutella Cake Roll

Just wondering if it’s absolutely necessary to use the sweet drops or can I skip that step?

You can skip them - they are used "to taste" so it depends on your preferred sweetness.

Hello Martina!
I made Marsmallow by this your recipe, it's wobderful, but I couldn't cover it with melted chocolate, the marshmallow stared to melt only I  touched it with chocolate. Any idea why?

Apologies for the delayed response! It means the chocolate was still hot/warm - you will need to bring it to room temperature before coating. I hope this helps!

You are awesome!

Hi!  Thanks so much for posting the recipe, just wondered if you ever tried to roast them?  😊

I don't think they can be roasted just like marshmallows but they do work well as topping when baked: Low-Carb Candied Yams with Marshmallows

I tried these today and the taste is great except the smell from the gelatin. I was wondering if you ever tried making them with jello for fruity flavors?

Hi Tracie, I haven't tried it but I would avoid jello - if I'm not wrong it contains artificial sweeteners and colourings? I know what you mean by the smell but I found that not all gelatine products do it. Have you tried Great Lakes Gelatin powder?

With Easter coming up I am wanting to make "peeps"  I have a silicone mold for the chick and the bunny "Peeps"  Have you ever tried this recipe in silicone molds?  I don't want to waste a batch (and the money) if you have found this unsuccessful.  I will be covering them in a sugar free chocolate.  Thanks for always putting together wonderful recipes for us.

Hi Tonnia, I haven't tried it but I suppose it may be risky in the sense that the marshmallow mousse solidifies quite quickly, just enough to spread it in the pan. It may be too stiff before you're done with the whole batch.

Yes they will definitely hold up and form nicely in a silicone or plastic candy mold.

This one is amazing. Is it okay if i do store them in room temperature ? Since gelatin will softened up in room temperature

I think they are better refrigerated. I kept them at room temperature and the top dried out too much.

I have a suggestion to try for alternate Rice Krispies. Yesterday I saw that someone used the big puffy pork rinds, broken into smaller pieces, as cereal. I thought for sure that would not work but I don't care for the puffy pork rinds so I broke mine into smaller pieces, put some sukrin gold and almond milk on and sure enough it was like a bowl of cereal. I would imagine if you accepted the irregularity and shape you may be able to turn them into a type of Rice Krispie Treat.

I haven't thought of that but will give it a try and share if my attempt is successful 😊

I searched and found tagatose online at Amazon. The original company went out of business apparently and a new company bought it. Amazon link Says it browns like sugar. I may have to try this with the tagatose.

Thank you, that's great to know. Swerve works great for browning, too!

Martina they taste great but there is one little problem. Mine were set instantly lol, forget about mixing them 3-5 min, 3 sec and it was too late. Maybe stronger jelatin, who knows. Now I have these two cups filled with a white foam 😂. Delicious never the less just have to add less next time.

Sorry to hear that, have you used gelatin or was it a vegetarian substitute? Some of my readers reported the same problem and realised that they didn't use beef gelatin but "Vege-gel". I hope the next batch is better! 😊

Now we just need to find a suitable substitute for Rice Krispies and I'll be set!!

I'll think of something! 😊

Have you ever tried a combination of TVP and flaxseed meal?

I am looking forward to making these but do you have any suggestions on how to make marshmallow creme? My nephew wants peanut butter and fluffernutter sandwichs.

Hi Tresa, although I haven't tried it, I would try and use some melted ghee or butter and whisk it with the marshmallow fluff before it sets.

I just tried this for the first time last night.  I ended up with enough to fill TWO 8x8 square pans to the top!  And today they taste really fluffy/spongy, like not nearly the "chew" that a real marshmallow would have.  The flavor is pretty good, but the texture isn't quite there.  Did I overmix?
I did accidentally use granulated Swerve instead of powdered, and I put the Stevia in with the whites instead of the gelatin (oops, on both counts) but the egg whites still fluffed up really well and the granulated sugar incorporated fine.  
Should I have left it with less volume so it would be a little more dense and chewy?

Hi Suzy, that sounds like a lot, maybe it was caused by the granulated sweetener (powdered sweetener would slightly deflate the egg whites). If you used granulated sweetener, you may have ended up with crispy and more fluffy texture. I don't think that the stevia mixed with the egg whites had any effect. They do get a little spongy, they are definitely not as dry and chewy as proper marshmallows but I think that using powdered sweetener should improve the texture.
