After a bake-off of 9 recipes, 38 testers agreed with @thepancakeprincess that William Greenberg Desserts has the best Black & Whites. "In my humble opinion (and in the opinion of many people who responded to my Instagram inquiry), William Greenberg takes the cake. The cookie has the perfect level of softness and slight moistness, there’s great flavor, the texture of the frostings are almost chewy-tender without being too soft and messy, and the flavor of the chocolate and vanilla frostings are also flavorful without being saccharine."
