About Us

It all started in 1946…

On his way back to New York after serving in World War II, Mr. Greenberg acquired the funds to open his dream bakery after a few lucky streaks while playing cards. Since signing his lease on the Upper East Side of Manhattan and opening the doors of WIlliam Greenberg Desserts, our bakery has been a favorite to generation after generation of New Yorkers.

From our classic Black & White Cookies, to our delicious brownies, and delectable rugelach, since opening in 1946 we have worked tirelessly to maintain Mr. Greenberg's standards of excellence; always using the freshest and best ingredients available to ensure we provide you with the best product possible.
