What Are Rice Krispies Treats?
Rice Krispies Treats are one of the most recognizable snack bars in the American pantry: crisp rice cereal bound together with melted marshmallow, pressed into a chewy, slightly sticky bar. Kellogg's (now sold under the Kellanova/WK Kellogg umbrella) sells two related but distinct products worth separating here, because they matter for different reasons if you're vegan: the original Rice Krispies cereal that started it all in the 1920s, and the packaged, ready-to-eat Rice Krispies Treats bars that have been a lunchbox staple since the 1990s. A lot of "is this vegan" confusion comes from people assuming the two products share an ingredient list. They don't, and the treats bar is the one that actually causes problems.
Ingredients: What's Actually in the Box
Straight from Kellogg's own SmartLabel ingredient disclosures, here's what's in each product.
Rice Krispies cereal: rice, sugar, contains 2% or less of salt, malt flavor, plus added vitamins and minerals (iron, niacinamide, vitamin B6, B2, B1, folic acid, vitamin D3, and B12).
Rice Krispies Treats Original Bars: toasted rice cereal (rice, sugar, salt, malt flavor), corn syrup, fructose, vegetable oil (soybean and palm oil with TBHQ for freshness), sugar, corn syrup solids, and 2% or less of vegetable glycerin, dextrose, gelatin, natural and artificial flavors (contains milk), salt, DATEM, acetylated monoglycerides, soy lecithin, and BHT for freshness.
Notice the difference. The plain cereal box is a short, mostly plant-derived list. The treats bar adds two clearly animal-derived ingredients that the cereal doesn't have.
Are Rice Krispies Treats Vegan?
No — Kellogg's Rice Krispies Treats are not vegan. The ingredient label lists gelatin outright, and the "natural and artificial flavors" used in the marshmallow layer are also flagged as containing milk. That's two separate animal-derived ingredients in one bar, not a borderline or "may contain traces" situation. If you're checking a box in your pantry right now and it lists gelatin on the back, that's a definitive no, not a maybe.
The plain cereal is a closer call. It doesn't contain gelatin, dairy, or any obviously animal-derived ingredient on the label — but it is fortified with vitamin D3, and Kellogg's does not disclose on its packaging or SmartLabel page whether that D3 comes from lanolin (sheep's wool grease, the far more common and cheaper commercial source) or from a lichen-based vegan source. Most strict vegans treat an undisclosed D3 as non-vegan by default, since lanolin is still the industry standard unless a brand explicitly states otherwise. If you want a definitive answer for a specific box, Kellogg's consumer affairs line or the the spvegan.com ingredient checker is the fastest way to confirm what's currently in your regional formulation, since ingredient sourcing can shift by plant and country.
The Gelatin Problem, Explained
Gelatin is a protein extracted by boiling collagen out of animal skin, bones, tendons, and connective tissue — typically from cows or pigs. In candy and marshmallow production, it's the ingredient that gives marshmallows their stretch and lets them re-melt into a gooey binder, which is exactly the job it's doing in a Rice Krispies Treat. It's the same reason marshmallow fluff, standard jet-puffed marshmallows, and most gummy candy aren't vegan either — gelatin shows up anywhere a manufacturer needs that specific chewy, springy texture cheaply and at scale. Plant-based marshmallow makers get a similar texture using agar (a seaweed-derived gelling agent), carrageenan, or pea protein instead, which is exactly what the vegan alternatives below are built on.
What About Plain Rice Krispies Cereal?
If your goal is just a bowl of cereal and not a snack bar, plain Rice Krispies is one of the more vegan-friendly options on the shelf in terms of what's actually listed — no dairy, no eggs, no honey, no gelatin. The only asterisk is that undisclosed vitamin D3 sourcing. Some vegans are comfortable eating it anyway, reasoning that the D3 in a fortified cereal is a trace amount either way; others avoid any undisclosed animal-derived vitamin on principle. If that asterisk bothers you, brands like Nature's Path, Barbara's, and most store-brand "crispy rice" cereals use vitamin D2 (which is always plant-derived) or skip D fortification altogether — check the label, since formulations do change.
Nutrition Facts: Treats Bar vs. Vegan Alternatives
| Product | Serving | Calories | Total Fat | Sugar | Protein |
|---|---|---|---|---|---|
| Kellogg's Rice Krispies Treats (Original Bar) | 1 bar (22g) | 90 | 2g | 8g | <1g |
| Blake's Crispy Treats (vegan) | 1 bar | 90 | ~1.5g* | 5g | ~1g* |
| GoodMallow Plant-Based Treats (vegan) | 1 bar (0.78oz) | ~100* | ~2g* | ~7g* | <1g* |
*Figures marked with an asterisk are approximate based on publicly listed serving sizes and ingredient panels where a full nutrition facts breakdown wasn't published; check the current package for exact numbers, since recipes and formulations do get tweaked.
The headline takeaway: swapping to a vegan version doesn't cost you anything nutritionally. Calories and macros land in the same neighborhood as the original, and Blake's actually comes in noticeably lower in sugar per bar.
Vegan Rice Krispie Treats: Brand-by-Brand Breakdown
Blake's Crispy Treats are fully vegan by design — the company states plainly that all of its products are vegan. Instead of gelatin, the marshmallow-style binder relies on chickpea water (aquafaba) and agar for structure, with inulin and sunflower seed adding body. They're sold in multi-packs (36, 72, or 108 bars) aimed partly at schools and fundraisers, which makes per-bar cost reasonable if you're stocking up, less so if you just want one bar to try. At 90 calories and 5g of sugar per bar, they undercut the original on sugar while matching it on calories.
GoodMallow makes individually wrapped, gluten-free, kosher, plant-based crispy rice treats using pea-protein-based marshmallows instead of gelatin ones, sold in small multi-packs (typically boxes of 6-24) through retailers like Vegan Essentials, Amazon, and Walmart. They run a little pricier per bar than a box of the original Kellogg's treats, which is typical for a smaller allergen-friendly brand, but the tradeoff is a genuinely gelatin-free, dairy-free bar with a similar grab-and-go format.
Dandies vegan marshmallows + any vegan butter is the DIY route: melt vegan butter, stir in a bag of Dandies (or another gelatin-free marshmallow brand), fold in a gelatin-free crisp rice cereal, and press into a pan. It's the cheapest per-serving option by a wide margin and lets you control sweetness, but it does require actually making the marshmallow-melting step yourself rather than grabbing a bar off a shelf.
How to Make Your Own Vegan Rice Krispie Treats
The classic recipe swap is straightforward: replace the two problem ingredients (gelatin-based marshmallows and, if you're being strict about it, the vitamin-D-ambiguous cereal) and the rest of the process is unchanged. Melt 3 tablespoons of vegan butter in a large pot, add a 10oz bag of vegan marshmallows, and stir until fully melted and smooth. Remove from heat, fold in 6 cups of a gelatin-free crisp rice cereal, press firmly into a greased 9x13 pan, and let it set for about 30 minutes before cutting into bars. It's a five-minute process with no baking involved, and it scales up or down easily.
Comparison Table: Store-Bought Original vs. Vegan Options
| Option | Vegan? | Format | Where to Buy | Best For |
|---|---|---|---|---|
| Kellogg's Rice Krispies Treats | No (gelatin + milk flavoring) | Individually wrapped bars | Any grocery store | Non-vegans |
| Blake's Crispy Treats | Yes | Bulk multi-packs | Company website | Fundraisers, schools, stocking up |
| GoodMallow | Yes | Small multi-packs, individually wrapped | Amazon, Vegan Essentials, Walmart | Grab-and-go snacking, allergy-friendly needs |
| Homemade (Dandies + vegan butter) | Yes | Made at home | N/A | Budget, customization, big batches |
Who Should Buy Which Option
If you're feeding a classroom, a bake sale, or a big group and want to buy in bulk without making anything, Blake's is the practical choice — it's built for exactly that use case. If you want an individually wrapped, allergy-conscious bar you can toss in a lunchbox or bag without worrying about cross-contact with common allergens, GoodMallow fits better. And if you already have vegan marshmallows and butter on hand, or you're cooking for a crowd on a budget, the homemade version is going to beat both on cost per bar and lets you dial in exactly how sweet or crispy you want it.
Final Verdict
Kellogg's Rice Krispies Treats: 2/10 for vegans — not because it's a bad snack bar, but because it's straightforwardly not vegan, with gelatin listed plainly on the label and milk-derived flavoring alongside it. There's no ambiguity to argue around here the way there is with, say, refined sugar or a "natural flavor" that could go either way. The plain cereal fares much better and lands closer to a 7/10 — vegan on paper aside from an undisclosed vitamin D3 source that cautious vegans may want to double check. For the actual treat-bar experience, Blake's Crispy Treats and GoodMallow both land around an 8/10: close in taste and texture to the original, free of gelatin and dairy, and easy enough to find online if not yet on every store shelf.
Frequently Asked Questions
Are Rice Krispies Treats vegetarian?
Yes, they're vegetarian — gelatin isn't meat itself, and there's no meat, poultry, or fish in the ingredient list. But gelatin is still an animal byproduct made from boiled-down animal collagen, so the bars aren't suitable for strict vegetarians who avoid animal-derived processing aids, and they're not vegan either way.
Is plain Rice Krispies cereal vegan?
It's about as close to vegan as a mainstream fortified cereal gets — no dairy, eggs, honey, or gelatin on the label. The only open question is the source of the added vitamin D3, which Kellogg's doesn't disclose, so strict vegans may want to look for a brand that specifies plant-derived D2 or a vegan D3 source instead.
What makes Rice Krispies Treats non-vegan specifically?
Two ingredients: gelatin, which is used to bind and stretch the marshmallow layer, and "natural and artificial flavors" that Kellogg's own label discloses as containing milk. Either one alone would make the product non-vegan; having both removes any ambiguity.
Can I use regular Rice Krispies cereal to make vegan treats at home?
Yes — the cereal itself isn't the problem, the marshmallows are. Swap in a gelatin-free marshmallow brand like Dandies and a vegan butter, and you can use the same box of cereal (or any gelatin-free crisp rice cereal) to make a fully vegan version at home.
Do any store-bought vegan versions of Rice Krispies Treats actually exist?
Yes. Blake's Crispy Treats and GoodMallow both make ready-to-eat, individually wrapped crispy rice treats built without gelatin, using agar or pea-protein-based marshmallows instead. Both are more niche than Kellogg's and mostly sold online rather than in every grocery aisle.
Why do manufacturers use gelatin instead of a vegan gelling agent?
Cost and consistency, mostly. Gelatin is cheap at industrial scale and behaves very predictably, giving manufacturers a reliable stretch and set every time. Plant-based alternatives like agar or pea protein can achieve a similar texture but often require more formulation work and can cost more per unit, which is part of why gelatin remains the default in mass-market candy and marshmallow products.
Is the vitamin D3 in Rice Krispies cereal always non-vegan?
Not always, but it usually skews non-vegan by default. The two common commercial sources of D3 are lanolin (from sheep's wool, non-vegan) and a lichen extract (vegan), and lanolin remains the more common, cheaper source across the packaged food industry. Since Kellogg's doesn't specify which one it uses, cautious vegans generally treat it as unconfirmed rather than assuming it's the vegan option.
Are other flavors of Rice Krispies Treats, like chocolate or s'mores, any different?
Generally no — the base marshmallow-and-gelatin issue runs across the Rice Krispies Treats line, and flavored versions typically add ingredients like chocolate coating or drizzle on top of the same gelatin-containing base rather than removing it. Always check the specific flavor's label, since coatings can introduce additional dairy ingredients like milk chocolate on top of the existing problem.
