If that were the case, to 'make an ask' would in this case mean to make the cookie, which it doesn't.
It seems like 'ask' is a verb, not a noun - in which case it is synonymous with 'request'.
People seem to be arguing that it's a 'more specific' form of 'request', but I can't really see how you could make a nonspecific request.
Edit: Ha! I even confused myself... 'Ask' here is indeed a noun - like 'request' when used as a noun - but it still seems to refer to be entire request, not just the object (which is the point I was trying to make).
