Carol Becker of William Greenberg Desserts demonstrates her famous black & white cookies plus a recipe from her cookbook, William Greenberg Desserts Bakes Vegan, at KJ Sisterhood's Heyman Auditorium event. RSVP required.
Voted number one in New York for their black & white cookies, which are soft, cake-like, and hand-iced with a chocolate-vanilla split that always lands correctly. The schnecken, brownies, and lemon squares are the other reasons regulars keep coming back, and the display case tends to clear out before noon.
Layered almond sponge with apricot jam, dipped in dark chocolate. A NYC classic.
Dense, fudgy chocolate brownie baked fresh daily—a New Yorker staple.
Soft, cake-like round hand-iced with a sharp chocolate-vanilla split. NYC's most-voted #1.
