Are Oreos Vegan?
It Depends
Classic Oreos contain no animal-derived ingredients and are widely considered accidentally vegan, but several varieties contain milk, egg, or whey, and Mondelez does not certify any Oreos as vegan due to milk cross-contamination in shared facilities.
The catch: Mondelez explicitly warns of "milk as cross contact" across all Oreo products, and a number of specific varieties, including Cakesters, fudge-coated, and ice cream sandwich formats, actually contain dairy or egg as listed ingredients.

Mondelez
Classic, Double Stuf, Golden, Thins, Mint, Birthday Cake, and most standard flavors contain no animal-derived ingredients and are broadly accepted by major vegan organizations as suitable for vegans. However, Oreo Cakesters contain milk and eggs; fudge-coated/chocolate-coated varieties (White Fudge-Covered, Cadbury Chocolate Coated) contain whey and milk solids; and Oreo Vanilla Ice Cream Sandwiches contain dairy.
Regional variation matters: Japanese Oreos contain milk powder, and some UK Peanut Butter Oreo varieties list milk. In the US, cane sugar is sometimes filtered with bone char during processing, this is a processing aid that does not appear in the final product, and The Vegan Society and most mainstream vegan organizations do not consider bone-char-processed sugar to make a product non-vegan.
Strict vegans who avoid bone-char sugar should note that Mondelez sources sugar from multiple suppliers without guaranteeing bone-char-free supply chains.
