My grandfather would make me these now and then. He’s from Ukraine

Sadly, Oreos appear to no longer be vegan - at least in right now, in Germany. For foods like cookies, instant noodles, and similar foods that are usually made in huge factories with a lot of other products, you’d see a note telling that the product may contain traces of xyz. A couple years back, you’d see that note on a pack of Oreos, ie. “may contain traces of milk” and possibly some nuts or something. These days, it says “may contain milk” which is an important distinction to make. Apparently, the factory gives themselves the leeway to substitute parts of the vegan ingredients with non-vegan ones if it’s more financially viable to them. The usual formula might be vegan, but you’d have no way of knowing if this particular batch happens to not have any non-vegan ingredients in them
