Standard Oreo cookies are not gluten-free — they contain wheat flour. Mondelez’s separate Gluten-Free Oreo line IS gluten-free.
No for standard Oreos. The classic Oreo cookie is made with unbleached enriched wheat flour as the second ingredient. Allergen declaration: “Contains: Wheat, Soy.” However, Mondelez launched a separate “OREO Gluten-Free” product line in January 2021 — Original, Double Stuf, and Golden — all GFCO-certified at <10 ppm, made with rice flour and oat flour instead of wheat. Always check the front of the box for the “Gluten Free” claim.
Oreos are one of the better gluten-free stories in mainstream candy and cookies: Mondelez launched a Gluten-Free Oreo product line in January 2021 that’s GFCO-certified at the strict <10 ppm threshold. The catch is that standard Oreos and Gluten-Free Oreos sit next to each other on the shelf at most grocery stores, and you have to check the front of the box every time.
What’s in Standard Oreos
Per Mondelez’s published ingredient list for the standard Oreo: “Sugar, unbleached enriched flour (wheat flour, niacin, reduced iron, thiamine mononitrate, riboflavin, folic acid), palm and/or canola oil, cocoa (processed with alkali), high fructose corn syrup, leavening, salt, soy lecithin, chocolate, vanillin.”
The Gluten-Free Oreo Product Line (Launched January 2021)
In January 2021, Mondelez launched OREO Gluten-Free as a separate product line. Available variants:
- OREO Gluten-Free Original Sandwich Cookies — GFCO certified
- OREO Gluten-Free Double Stuf Sandwich Cookies — GFCO certified

Gluten-Free Oreo ingredient list: sugar, white rice flour, tapioca starch, palm oil, soybean and/or canola oil, whole oat flour, cornstarch, cocoa, invert sugar, soy lecithin, baking soda, salt, xanthan gum, chocolate, artificial flavor. The cookie is rice-flour-and-oat-flour based, not wheat-flour based.
Cross-Contamination Risk
Manufacturing
N/A — Wheat by Formulation
- Standard Oreos: wheat flour is the 2nd ingredient by weight.
- “Contains: Wheat, Soy” is Mondelez’s official allergen declaration.
- Gluten-Free Oreos: GFCO-certified at <10 ppm, made in separate production.
Shared Snack / Party
Medium
- Standard Oreos are extremely common shared snack — cross-contact in bowls.
- Cookie crumbs migrate easily.
- Store Gluten-Free Oreos separately if other household members eat standard.
Home
Medium
- Store on separate shelves; standard Oreos cross-contaminate shared surfaces.
- Use dedicated cookie tray or wash thoroughly between gluten and GF cookies.
What to Look For — Or Avoid
- “Gluten Free” claim on the front of the box (only on the GF Oreo SKU)
- GFCO certification mark on the GF Oreo packaging
- Ingredient list reads “white rice flour” and “whole oat flour” — that’s the GF SKU
- Standard Oreo packaging (any variant: Original, Mint, Birthday Cake, Mega Stuf, seasonal) — all contain wheat
- “Contains: Wheat, Soy” allergen callout (standard Oreos)
- Oat sensitivity — GF Oreos contain oat flour
Frequently Asked Questions
Are Oreos gluten-free?
Standard Oreos are NOT gluten-free — they contain unbleached enriched wheat flour as the second ingredient. Mondelez launched a separate “OREO Gluten-Free” product line in January 2021 — Original, Double Stuf, and Golden variants — all GFCO-certified at <10 ppm. Always check the front of the box for the “Gluten Free” claim before buying.
Are Gluten-Free Oreos really gluten-free?
Yes. Gluten-Free Oreos are certified by GFCO at the strict <10 ppm threshold (half the FDA standard). They are made with white rice flour, tapioca starch, and whole oat flour (GFCO-certified oats) instead of wheat flour. Mondelez explicitly labels them “Gluten Free” on the front of the box.
Which Oreo flavors come in gluten-free?
Currently three: Gluten-Free Original Sandwich Cookies, Gluten-Free Double Stuf, and Gluten-Free Golden. Other Oreo flavors (Mint, Birthday Cake, Mega Stuf, seasonal limited editions) are only available in their standard wheat-based formulation.
Can celiacs with oat sensitivity eat Gluten-Free Oreos?
No. Gluten-Free Oreos contain whole oat flour (GFCO-certified, so very low gluten cross-contact), but oats themselves trigger an immune response in approximately 1 in 5 people with celiac disease due to a separate protein called avenin. If you react to certified gluten-free oats, Gluten-Free Oreos may not be safe for you.
Are Oreo Thins gluten-free?
No. Oreo Thins use the same wheat-flour cookie base as standard Oreos and contain gluten.
Where can I buy Gluten-Free Oreos?
Gluten-Free Oreos are stocked in the regular cookie aisle of most mainstream grocery stores (Kroger, Walmart, Target, Safeway, Publix) alongside standard Oreos. They are also available online via Amazon, Mondelez’s online store, and most grocery delivery services. Look for “Gluten Free” prominently on the front of the box and the GFCO certification mark.
