A list that started off as a note on my phone

New York City

Milk and Cookies: so far, my favorite ever - soft, sweet, slightly chewy and very chocolatey. Milk and Cookies also churns out other delectable bakes like their ridiculously chocolatey brownie!
Baked: though this cookie looks great on the outside, I personally found its texture to be a little dry and hard
Levain: world famous and delectable, but not my personal favorite because of its slightly unconventional shape, baking process, and ultimately texture. update: they recently opened up a new branch and I've found myself returning to UWS just for these cookies, so I guess I take back what I said!
Jacques Torres: a king of kings, beautifully chocolatey, crunchy yet fudgy, and actually enormous. JT will always be my man - don’t miss the Mudslide cookie too!
Insomnia: a classic and my go-to on a windy winter’s night - reliably fast, warm, and gooey
Max Brenner: reliably a palace of chocolate, but sadly home to one of the worst chocolate chip cookies I’ve had in NYC - hard and stale, lacking chocolate, and boring
Rubyzaar Baked: a hidden gem only to be found in Williamsburg on weekends - a gorgeous array of carefully crafted cookies, but the winner in my heart was the Classic Rock for its hearty chocolate chunks and tasteful sprinkle of rock salt
Starbucks: not mind-blowing, but pretty fine for a sugar pick-me-up since it is really ALWAYS there. Alternatively, just down with coffee
Schmackary’s: very sweet, yet very beautiful. Fudgy, soft, and rich but go easy on portions because these cookies will sugar you out fast
Dominique Ansel: not a cookie, but almost - the cookie shot is filled to the brim with warm milk and is marvellous just to look at. Very fun, but not your everyday cookie - esp. w/ DA's consistently long lines
Momofuku Milk Bar: despite the worldwide acclaim, don’t come here for the cookie - stick to the icecream (if that's what you're into!)
La Colombe: gluten free (if that matters), and sort of everywhere around the city. A little crunchier than most - for those who also like their fries crispy
Alamo Drafthouse Cinema: really cool, mainly because warm cookies were served to us in a theater as we were watching a movie, but also warm, dense, and fragrant
Balthazar Bakery: chewy, chocolatey and basically pleasant, but not exactly the city’s most memorable cookie
: awesome cookies, well-rounded chewy texture and very chocolatey. unpopular opinion, but go for the cookie and not the dough
By CHLOE: these vegan cookies are larger than the size of an average human head and are sprinkled all over with chocolate, which is awesome, but just a little too crunchy and thin for my liking
Maman: thick block of chocolate right in the middle with hazelnuts sprinkled throughout; very satisfying and definitely a top contender.

SF Bay Area

Tin Pot Creamery: tried in Palo Alto but they have a few branches spread across South Bay. I really, really liked their cookie and the chocolate melted just the right amount for a great summer's day treat. Their icecream is also superb for those who are interested in both!
Philz: obviously a coffee place at heart, with a growing selection of sweet treats! the cookie was honestly a bit on the dry/brittle end for me, but would be better suited to those who prefer more dough than chocolate! in any case, it's hard to dislike philz

Hanover, NH

FoCo (!!): objectively pretty awesome cookies, reminds me a lot of Insomnia but have eaten so many in a week that I almost had to take a FoCo cookie sabbatical once. Basically, dangerous but in a good way
My Brigaderio: these cookies are thick and slightly salty in such a good way. Best cookies in Hanover, which potentially doesn't say too much, but trust me these are phenomenal
The Box Food Truck: cookies with oatmeal sprinkled on top, which surprisingly works very well. Overall, a good purchase and snack but nothing too exciting
