William Greenberg Desserts is serving up seasonal wins through their spin on the black and white cookie, now available in pumpkin and sweet potato flavors. The cookies are very cake-like (no crunch) and they're topped evenly with black and white frosting, kind of like a small, edible, yin-yang symbol. The cookes cost $3.50 and are available at both William Greenberg's Plaza Food Hall (1 W 59th St.) spot, as well as their original Upper East Side location (1100 Madison Ave.).
