Well, the answer is "I do not know" Now, if I had to guess, this are "a new kind of cookies" so they just took a name that went with it (like they did with biscuits https://www.biscuitsec.org/ https://www.biscuitsec.org/) There are many chances that they got he name wrong and they meant Macaron (with one O instead of two). Those are "layered" cookies, which bring some resemblance on how "caveats" can be understood.
