Why
The classic Oreo recipe is flour, sugar, palm and rapeseed oil, cocoa, glucose-fructose syrup, raising agents, salt, emulsifiers (soya lecithin) and flavouring — no dairy or egg. Mondelez states the biscuits are made on lines shared with milk, which is why the pack says they are not suitable for milk allergy sufferers. Filled and seasonal variants (white chocolate, some limited editions) do contain milk.
What to check on the label
- The ingredient list on your own pack — Oreo recipes differ by country and change over time
- Milk, whey, casein, lactose, egg, honey, gelatin, carmine (E120) and shellac (E904) in the list
- "May contain milk" is an allergen cross-contamination note, not an ingredient — most vegans still buy it

Questions people ask
Is Oreo certified vegan?
Certification is separate from the recipe. Many products with no animal ingredients carry no vegan mark because the maker will not rule out shared production lines. Check the pack for a registered vegan trademark, and treat the ingredient list as the primary evidence.
Does the answer change between countries?
Often, yes. The same brand name can use different fats, emulsifiers, colours or whey depending on the plant that made it, so always read the local label rather than an answer written for another market.
