Are There Sugar-Free Marshmallows? | Yes—When You Know Where to Look

If you’ve scanned the candy aisle at your local supermarket and come up empty, you’re not imagining it. Sugar-free marshmallows are real, but they occupy a specialty corner of the market rather than the mainstream shelves. Most are sweetened with monk fruit, stevia, allulose, or other sugar substitutes, and they’re marketed primarily to keto and low-carb shoppers. The good news: you have more options than the grocery store suggests, including several solid store-bought brands and a straightforward homemade route.

Where to Buy Sugar-Free Marshmallows in the U.S.

Your best bet is shopping online rather than hunting through physical store aisles. While some brick-and-mortar locations do carry them, selection varies widely by region and retailer. The brands below are the most established names in the sugar-free marshmallow space.

• ChocZero Keto Sugar Free Marshmallows — marketed with 0g fat and 0g sugar added, gluten free, and keto-friendly. Sold directly through ChocZero’s product page and on Amazon.
• ChocZero S’Mallows Vanilla — a 10.5 oz (300 g) bag of no-sugar-added mini marshmallows sweetened with monk fruit. Sugar free, fat free, and keto friendly, made with bovine gelatin. Carried by Target both in stores and online.
• La Nouba Sugar-Free Marshmallows — low calorie, low carb, fat free, and gluten free. Available as two-packs on Amazon and four-packs at Walmart. The Walmart version is also casein free, soy free, and corn free.

Shopping for zero sugar marshmallows doesn’t have to be a guessing game — our tested roundup of the best zero sugar marshmallows compares the top brands side by side so you can pick the right one for your pantry.

What “Sugar-Free” Actually Means

Here’s the catch most shoppers miss: sugar-free doesn’t mean carb-free or calorie-free. Retail claims focus on sugar content, not total carbohydrates, and the two are very different numbers.

ChocZero’s products emphasize “0g sugar added” with a keto positioning. La Nouba markets low-carb and fat-free benefits. Neither promises zero carbs. If you’re tracking macros strictly, read the nutrition panel on the specific product you buy rather than assuming all sugar-free marshmallows are interchangeable.

The sweetener matters for more than just taste. ChocZero uses monk fruit. La Nouba’s formula doesn’t rely on sugar alcohols. And if you’re shopping internationally, Double ‘D’ Sugar Free Marshmallows from New World in New Zealand use stevia. These different sweetener systems produce noticeably different textures and aftertastes.

How to Make Sugar-Free Marshmallows at Home

Making your own gives you full control over ingredients and texture, and it’s simpler than most people expect. The process mirrors traditional marshmallow-making with one key difference: you’re substituting a sugar-free sweetener for granulated sugar.

1. Bloom the gelatin. Sprinkle gelatin over cold or warm water and let it sit for 5–10 minutes until it absorbs the liquid and softens.
2. Cook the syrup. Heat your sweetener with water until it reaches the soft-ball stage — typically 237°F to 245°F depending on your recipe and sweetener. This is where a candy thermometer earns its keep.
3. Whip it. Pour the hot syrup into the bloomed gelatin and beat immediately. Keep whipping until stiff peaks form and the mixture turns thick and fluffy.
4. Set and cut. Spread into a lined pan and let it sit until firm, usually 2 hours to overnight. Cut with a greased or wet knife to prevent sticking.

Recipes commonly use allulose, Swerve (erythritol), xylitol, stevia, or monk fruit blends. Some bakers add whey protein powder to improve structure. The thermometer precision matters — hitting the right temperature window is what lets the marshmallows whip properly and set firmly.

One safety note: if you use xylitol in your recipe, keep the finished marshmallows well away from dogs. Xylitol is highly toxic to canines, even in small amounts.

Common Mistakes to Avoid

The biggest error is assuming all sugar-free marshmallows are the same. Formulas differ materially — a monk fruit marshmallow behaves differently in a s’more than one made with erythritol, and neither will melt exactly like a sugar marshmallow.

Also, don’t overlook ingredient compatibility. Several store-bought brands use gelatin or bovine gelatin, which rules them out for vegetarians, vegans, and anyone avoiding beef-derived ingredients. If that matters to you, check the ingredient list before ordering.

Finally, don’t judge homemade results on your first attempt. Marshmallow-making rewards precision, and a slightly low syrup temperature produces a softer, sticker result than you want. The second batch almost always comes out better than the first.
