Most marshmallows are gluten-free. The standard recipe is just sugar, water, and gelatin, none of which contain gluten. However, some brands add wheat-derived ingredients like wheat starch or glucose syrup made from wheat, so you can’t assume every bag on the shelf is safe.
What Makes Most Marshmallows Gluten-Free
A basic marshmallow is one of the simplest candies you’ll find. Sugar gets dissolved in water, gelatin provides the structure, and corn syrup keeps things smooth. None of these ingredients come from wheat, barley, or rye. Many marshmallows produced in the United States stick to this straightforward formula, which means they’re naturally free of gluten without any special processing.
The texture of marshmallows comes from whipping air into the gelatin-sugar mixture, not from any flour or grain-based thickener. That’s why marshmallows tend to be a safer bet than many other packaged sweets, where wheat flour often sneaks in as a binding or coating agent.
Ingredients That Can Add Gluten
Some marshmallow brands, particularly those sold outside the United States, use wheat starch as a dusting agent to keep marshmallows from sticking together, or they use glucose syrup derived from wheat as a sweetener. These additions introduce gluten into an otherwise safe product.
When checking labels, watch for these terms that signal gluten:
- Wheat starch or wheat flour
- Wheat protein or hydrolyzed wheat protein
- Malt (derived from barley)
- Modified food starch (usually corn-based in the US, but can be wheat-based in other countries)
You might also see Latin names on specialty or imported products: triticum vulgare (wheat), triticum spelta (spelt), hordeum vulgare (barley), or secale cereale (rye). These all contain gluten.
How Popular Brands Stack Up
Jet-Puffed, made by Kraft, is the most widely sold marshmallow brand in the US. Their marshmallows contain no gluten ingredients and are reportedly not subject to cross-contamination during manufacturing. The one caveat: Kraft does not put a “gluten-free” label on the packaging, so there’s no formal guarantee backed by third-party testing. For most people avoiding gluten, Jet-Puffed is considered safe, but those with celiac disease who want an extra layer of assurance may prefer a brand that makes an explicit claim.
Campfire marshmallows go a step further. The company states that their marshmallows are gluten-free, dairy-free, and nut-free, and that they’re made in a facility free from wheat. That dedicated facility eliminates the cross-contamination concern entirely.
Peeps, the seasonal marshmallow chicks and bunnies, are labeled gluten-free. Their ingredient list is clean: sugar, corn syrup, gelatin, and small amounts of coloring and preservatives. No wheat-derived ingredients appear in any variety, including flavored versions like cotton candy.
Vegan Marshmallows and Gluten
Vegan marshmallows skip gelatin (which comes from animal collagen) and use plant-based alternatives to get that fluffy texture. Dandies, one of the most popular vegan brands, uses tapioca syrup, tapioca starch, cane sugar, and carrageenan (a seaweed-derived thickener) instead. The product carries a gluten-free claim on its packaging. It does contain soy protein, so that’s worth noting if you have multiple food sensitivities.
Because vegan marshmallows rely on starches for structure, checking the source of those starches matters more than it does with traditional marshmallows. Tapioca and corn starch are gluten-free. Wheat starch is not.
What “Gluten-Free” on the Label Actually Means
In the United States, the FDA requires any product labeled “gluten-free” to contain less than 20 parts per million of gluten. The product also cannot contain any ingredient that is wheat, rye, or barley, or any ingredient derived from those grains that hasn’t been processed to remove gluten below that 20 ppm threshold. This applies to labels that say “gluten-free,” “no gluten,” “free of gluten,” or “without gluten.”
In the UK and EU, the threshold is the same: 20 milligrams per kilogram (equivalent to 20 ppm). But European rules also allow a “very low gluten” label for products containing up to 100 ppm, a category that doesn’t exist in US labeling. European regulations require any cereal containing gluten to be specifically named and visually emphasized in the ingredients list, so wheat starch in a European marshmallow would appear in bold or capital letters. This makes spotting gluten on imported marshmallows relatively straightforward if you know to look for the emphasized text.
Practical Tips for Buying Marshmallows
If you have celiac disease or a serious gluten sensitivity, the safest approach is to buy a brand that explicitly labels its product gluten-free and ideally manufactures in a wheat-free facility. Campfire checks both boxes. Jet-Puffed is likely fine but lacks the formal label.
Store-brand and imported marshmallows deserve a closer look at the ingredients list. Marshmallows from the UK, Europe, or Asia are more likely to use wheat-based glucose syrup or wheat starch as a coating. If you’re buying marshmallows for s’mores, hot chocolate, or baking, the same rules apply to mini marshmallows and marshmallow creme as to regular-sized ones: check the label every time, because formulations can change between product lines from the same brand.
Flavored and coated marshmallows carry slightly higher risk than plain ones. Chocolate-dipped, cookie-crumb-coated, or cereal-studded varieties may introduce gluten through their toppings even when the marshmallow base is safe. Read the full ingredient list rather than relying on the front-of-package claims alone.
