Classic Newyork Black and white cookies: the NYC bakery icon you can bake at home

There’s a reason these bold, half-vanilla, half-chocolate beauties have a cult following. Classic Newyork Black and white cookies deliver the best of both worlds: a soft, cake-like cookie base crowned with glossy fondant in two flavors. I’ve baked them for office parties, school fairs, and weekend coffee runs, and they disappear faster than any chocolate chip batch. The magic is in the texture (pillowy, not crumbly) and the icing (shiny, set, and not too sweet). Once you learn a few pro moves, Classic Newyork Black and white cookies are surprisingly approachable—even without fancy bakery gear.

What defines Classic Newyork Black and white cookies

Ingredients and equipment for Classic Newyork Black and white cookies

• Flour: All-purpose works well; weigh if possible for consistency.
• Leavening: Baking powder for lift; a touch of baking soda helps browning.
• Fat: Unsalted butter for flavor, At their core, Classic Newyork Black and white cookies are more like mini cakes than crisp cookies. The dough uses a higher ratio of liquid—typically milk and sour cream—to create that signature dome and tender crumb. The hallmark finish is a two-part fondant: vanilla on one half, chocolate on the other. New York institutions like Zabar’s and William Greenberg serve versions with a smooth, satiny glaze that sets firm to the touch but stays pleasantly soft when you bite. Food writers and baking experts (see Stella Parks/Serious Eats plus a little neutral oil for moisture.
• Dairy: Sour cream (or Greek yogurt) for tenderness and subtle tang.
• Flavor: Vanilla extract and a pinch of salt.
• Icing: Confectioners’ sugar, light corn syrup (for sheen and stability), milk or water, vanilla; Dutch-process cocoa for the chocolate half.
• Tools: Half-sheet pans, parchment, medium scoop (about 3 tablespoons), and an offset spatula.

From experience, a scoop ensures uniform size so your Classic Newyork Black and white cookies bake evenly and stack neatly in gift boxes.The New York Times Cooking) agree: the flat side gets iced, not the rounded top, for a clean, professional look and better adhesion

Step-by-step: bake Classic Newyork Black and white cookies like a pro

1. Make the batter. Cream soft butter and sugar until light and fluffy, 2–3 minutes. Beat in eggs one at a time. Mix in vanilla and sour cream. Whisk flour, baking powder, a pinch of baking soda, and salt; fold in alternately with milk until just combined. The batter should be thick but scoopable—more cake batter than cookie dough, exactly what you want for Classic Newyork Black and white cookies.
2. Portion and bake. Line pans with parchment. Scoop 3-tablespoon mounds, spacing generously (they spread). Smooth tops with damp fingertips for tidy domes. Bake at 350°F (175°C) for 12–15 minutes, rotating once. They’re done when edges are pale gold and centers spring back. Cool completely on racks; icing won’t set on warm cookies.
3. Mix the white fondant. Whisk confectioners’ sugar, a tablespoon of corn syrup, and just enough milk or water to make a thick, pourable glaze. Add a drop of lemon juice or vanilla to keep the flavor bright and the color vibrant.
4. Mix the chocolate fondant. Whisk cocoa into half of the white glaze. Adjust with drops of water to match the consistency; chocolate thickens quickly.
5. Ice the flat side. Flip. Use an offset spatula to spread white fondant over one half. Let it start to set (5–10 minutes). Finish the other half with chocolate. Aim for a slight overlap at the center line for a seamless divide on your Classic Newyork Black and white cookies.

Real-world note: If the glaze gets crusty while you work, whisk in 1–2 teaspoons of warm water. If it runs off the edge, it’s too thin—add more sugar.

Pro tips, science, and variations for Classic Newyork Black and white cookies

• Texture matters. The sour cream’s acidity tenderizes gluten, yielding the classic plush bite. America’s Test Kitchen and King Arthur Baking both emphasize sour cream for cake-style cookies.
• Shine insurance. A little corn syrup prevents a dull, chalky finish and helps the fondant set with that deli-case gleam associated with Classic Newyork Black and white cookies.
• Even halves. Draw a faint center line in the white icing with your spatula; it acts as a guide when you add the chocolate.
• Storage. Keep at cool room temp in a single layer for 24 hours, then stack with parchment. They stay soft 2–3 days. For longer storage, freeze un-iced cookies up to 2 months; thaw and ice before serving.
• Flavor twists. Add a whisper of almond extract to the white side, or espresso powder to the chocolate for mocha-laced Classic Newyork Black and white cookies. Citrus lovers can add lemon zest to the batter for a deli-style variation.

From testing, slightly thicker batters produce cleaner edges; too loose and the cookies spread thin, making icing trickier.
