Black and white cookies are a mainstay in New York City’s bakeries and delis. The cookies have a soft cake-like texture with the flat side decorated with half chocolate icing and half vanilla icing. There is also a hint of lemon and vanilla extracts. All of this combined makes it a perfectly delicious combination of cake and cookie. The origin of the treat is usually traced to Glaser’s Bake Shop in the Yorkville section of Manhattan, where Bavarian immigrants opened shop in 1902. With this recipe, there's no need to travel to New York City—you can make black and white cookies in your very own kitchen.

  • 1 cup unsalted butter (softened)

  • 1/2 teaspoon vanilla extract
  • 1/2 teaspoon lemon extract
  • 2 1/2 cups cake flour
  • 2 1/2 cups all-purpose flour

  • 1/2 teaspoon salt

  7. For each cookie, scoop 1/4 cup of batter and place on the parchment-lined baking sheet. Use a knife or offset spatula to shape each cookie into a 4-inch circle. Do not flatten. Space the cookies 2 inches apart. Bake the cookies until the edges begin to brown, 15 to 17 minutes.

  2. Remove half of the frosting to a double boiler set over, but not touching, simmering water. Add the chocolate. Warm the mixture, stirring, until the chocolate is melted and the frosting is smooth. Add an additional few drops of warm water as necessary to the chocolate frosting to achieve a smooth spreadable consistency. Remove from the heat.
