"For many, William Greenberg’s name is synonymous with the iconic black and white cookie. Opened in 1946, the Upper East Side bakery’s classic take on these deceptively named, cake-like cookies boasts a moist and sponge-like texture. The team recommends the less commonly found schnecken, a kind of pecan cinnamon twist, as well as pecan brownies that made an appearance on Mad Men. There are several locations in Manhattan." - John Tsung, Eater Staff
