Jess Finally Tries Halfmoon Cookies If you remember a few weeks back we discussed Black and White cookies and how some people in New York call them Halfmoon cookies. In my honest opinion, if you live in downstate New York and call them Halfmoons, your NY card should be revoked. With that being said, I learned in the process that Halfmoon cookies are their own entity. They are completely different than our beloved Black and White cookies. For instance, Halfmoon cookies were founded in Utica, New York and have a chocolate cookie base. This whole conversation sent me into a rabbit hole of Upstate NY foods that I needed to try.
