Order #20497 was placed on 6/30/25. I paid for 2 day shipping so my family could have the cookies on their flight from Kauai on 7/4/25. The FedEx tracking shows the package has been sitting in Oakland, CA since 7/2/25. W. Greenberg rep said “Can I axe you a question? Do you think it’s our fault?…..” HORRIBLE customer service, disappointing experience.
I saw ALL people leave empty-handed since there is not a price list or even identifying product signage in the location on the UWS. The browbeaten employees explained I could find the prices online. We purchased a Babka and cookies but it was not a pleasant bakery experience. Step over to nearby Levain, they post prices.
BEST black and whites anywhere!

William Greenberg Desserts is a bakery known for its legendary black and white cookies, which are like edible happiness in disc form. The mini black & white cookies with green & white frosting and brown & green frosting are highly recommended, beautifully boxed with a red ribbon. The quality of the baking is top-notch, and the black and white cookies are a must-try for anyone in need of a culinary pick-me-up. While the service can be surly at times, with some employees not providing all available options, the bakery maintains its reputation for delicious treats.
Located on the Upper East Side, William Greenberg Desserts may not be as well-known as larger tourist attractions, but it is certainly a hidden gem. The cookies are perfectly sized, and their light, cakey texture is a delightful surprise. The balance of chocolate and vanilla flavors is spot on. Though the warm weather can limit seating, the friendly and welcoming staff make the experience enjoyable. Other tempting treats, such as rugelach, are also available. Overall, William Greenberg Desserts is a must-visit for anyone seeking authentic New York-style baked goods.
