What is the oldest cookie still made?

Could you please elaborate on what you mean by "the oldest cookie still made"? Are you referring to the longest-lasting recipe that's still in production, or perhaps a specific brand of cookie that's been manufactured for a particularly long time? Clarifying this would help me provide a more accurate and informative answer. Additionally, is there a particular region or country you're interested in, as certain cookies may be unique to specific cultural traditions or geographic locations?
