Black and White Cookies: A NYC Tradition Explained

There are certain foods that belong so completely to a place that encountering them anywhere else feels like running into an old friend in a foreign city. The black and white cookie is one of those foods, and the place it belongs to is New York City.

If you grew up in the tri-state area, you know the black and white cookie. You have seen them stacked on bakery counters, wrapped in cellophane at delis, and piled in the display case at every corner bodega in Manhattan. They are as much a part of the New York food landscape as pizza slices and dirty-water hot dogs. And yet, outside of the Northeast, most people have either never heard of them or have only encountered sad imitations that bear little resemblance to the real thing.

At Dan's Bagels, we serve real black and white cookies. Let me tell you why they matter, how they are made, and what makes a good one.

A Brief History of the Black and White

The black and white cookie has its roots in the German and Eastern European baking traditions that came to New York with the waves of immigration in the late 19th and early 20th centuries. The cookie itself is likely descended from a German pastry called the Amerikaner — a soft, dome-shaped cake cookie topped with a glaze. As German bakers set up shop in New York City, the cookie evolved. Someone — nobody knows exactly who or when — had the idea of splitting the glaze into two halves: one chocolate, one vanilla. The black and white was born.

By the mid-20th century, the black and white cookie was ubiquitous in New York. Glaser's Bake Shop on the Upper East Side, which operated from 1902 to 2018, was widely considered the gold standard. But every neighborhood had its version. The Upper West Side, the Lower East Side, Brooklyn, Queens — every bakery made them, and every customer had an opinion about whose was best. The debate over the best black and white in the city was as heated and ongoing as the debate over the best pizza or the best bagel.

The Seinfeld Moment

In 1994, the black and white cookie achieved national recognition thanks to a Seinfeld episode called "The Dinner Party." In the episode, Jerry picks up a black and white cookie from a bakery and delivers what became one of the show's most quoted monologues:

“Look to the cookie, Elaine. Look to the cookie.”

— Jerry Seinfeld, Season 5, Episode 13

Jerry's point — delivered with his characteristic mix of sincerity and absurdity — was that the black and white cookie represents racial harmony. Two races of flavor, existing peacefully on a single cookie. "If people would only look to the cookie, all our problems would be solved." It was a joke, but it was also the kind of observation that made Seinfeld resonate: a small, specific New York thing elevated into a universal metaphor.

The episode introduced the black and white cookie to millions of Americans who had never seen one. Suddenly, people across the country were searching for them, asking about them, trying to order them. But most of what they found outside New York was disappointing — dry, flavorless cookies with cheap icing that cracked and flaked off. The real thing, it turned out, was harder to replicate than it looked.

Anatomy of a Real Black and White

A proper black and white cookie is not actually a cookie in the traditional sense. It is closer to a small, flat cake. The base is made from a sponge cake or pound cake batter — soft, moist, and tender, with a fine crumb that is denser than a cupcake but lighter than a shortbread. It should have a faint lemon or vanilla aroma in the batter. The texture should be yielding but not crumbly — it should hold together when you pick it up, but give easily when you bite into it.

The bottom is flat from the baking sheet. The top is slightly domed. And covering that dome, from edge to edge, is the icing — half chocolate, half vanilla, divided by a clean, straight line down the center.

The Icing: Fondant, Not Frosting

This is where most imitations fail. The icing on a real black and white cookie is fondant — a cooked sugar icing that is smooth, slightly glossy, and sets to a soft, non-brittle finish. It is not buttercream frosting. It is not royal icing. It is not a glaze. Fondant has a specific texture: firm to the touch but yielding when you bite through it, with a clean sweetness that complements rather than overwhelms the cake base.

The vanilla side is bright white — made with confectioners sugar, corn syrup, and vanilla extract, cooked to the right temperature and poured while warm so it levels itself into a perfectly smooth surface. The chocolate side uses the same base with the addition of cocoa powder (and sometimes melted chocolate), creating a rich, dark brown that contrasts sharply with the white half.

The line between the two halves should be clean and sharp. This is a point of pride for bakers. A wobbly line, an overlap, or bleeding between the halves is a sign of carelessness. The best black and white cookies have a razor-straight division that looks almost mechanical. It is a small detail, but it is the kind of detail that separates a bakery that cares from one that does not.

The Great Debate: Which Side First?

Every black and white cookie enthusiast has a strong opinion about which side to eat first. Some start with the chocolate side, saving the vanilla for last. Others begin with vanilla, building toward the chocolate. A minority — the true iconoclasts — bite straight down the center line, getting both flavors simultaneously.

There is no wrong answer, but I will tell you that most New Yorkers I know start with the chocolate side. The reasoning is that the vanilla fondant is slightly more delicate and nuanced, making it a better finish. The chocolate is bolder and sets the stage. Dan starts with the vanilla. We have agreed to disagree on this, as we do on many things.

Why We Carry Them at Dan's Bagels

When Dan and I were building the Dan's Bagels concept, we knew from the beginning that we wanted to be more than a bagel shop. We wanted to recreate the full New York deli and bakery experience — the kind of place where you walk in and everything on the counter tells you that the people behind it know what they are doing. Dr. Brown's soda. Real Taylor Ham. House-made cream cheese. And black and white cookies.

We source our black and white cookies from a bakery that makes them the right way — real fondant icing on a proper cake base, with the clean halved presentation and the right size (they should be big — at least the diameter of your palm, and substantial enough to feel like a real dessert, not a token afterthought).

For our customers who grew up with black and white cookies, seeing them in our case is a homecoming moment. For our Texas-born customers, they are a discovery. And for everyone, they are a reminder that some traditions are worth preserving — that there is a reason certain foods have survived for over a hundred years in a city that discards trends overnight.

A Cookie Worth Looking To

Jerry Seinfeld was joking when he told Elaine to look to the cookie. But he was also right. The black and white cookie is a small, sweet, perfectly balanced thing — two flavors, two colors, one cookie, and a hundred years of baking tradition in every bite. It is not trying to be sophisticated. It is not trying to be trendy. It is just trying to be good, in the way that things made with care and tradition and a little bit of pride have always been good.

“Some traditions survive because they are too good to abandon. The black and white cookie is one of them.”

Next time you are at Dan's Bagels, grab one. Start with whichever side you prefer. And if someone asks you what a black and white cookie is, you now have the answer.
