We transform our legendary black and white cookies into personalized masterpieces for your special events, delivering New York's most iconic treat tailored specifically to your celebration. Our expert decorators hand-color each cookie with unique combinations while maintaining the perfect vanilla-and-chocolate fondant icing balance that has made William Greenberg's version the gold standard among NYC bakeries for over 75 years. Whether ordering for corporate events, bar and bat mitzvahs, wedding favors, birthday parties, or holiday gifts, each piece starts with our signature tender cake base recipe, providing the ideal canvas that travels beautifully and photographs perfectly. Our customization service accommodates orders from intimate dozens to grand-scale events requiring hundreds of pieces, with options including individually wrapped treats with coordinating ribbon colors and elegant gift boxes. Beyond traditional icing, we offer colors to match wedding themes, school pride for graduations, company branding for corporate gifts, or holiday-specific designs while preserving the authentic taste that defines a true New York cookie. Under Carol Becker, our Upper East Side bakery pioneered these colorful variations in Manhattan, bringing meticulous attention to every custom order and ensuring your personalized treats maintain the exceptional quality that makes discerning New Yorkers choose William Greenberg for their most important occasions. Available for pickup or delivery nationally, William Greenberg's customized bBlack & Whites blend tradition with creativity, honoring the craftsmanship Carol Becker and her team have perfected through decades of serving Manhattan's most memorable moments.
