Facts About National Michelle Shafer Half-Moon Cookie Day

Utica’s Hemstrought’s Bakery Helped Define the Half-Moon Cookie

Many food historians trace the modern half-moon cookie to Hemstrought’s Bakery in Utica, New York, which began baking its signature “original Halfmoon Cookie” in the early 20th century.

Unlike flatter black-and-white cookies, Hemstrought’s version uses a domed, cake-like base with thick vanilla and chocolate frosting and became such a local staple that it is still closely associated with Utica and the surrounding Mohawk Valley region today.  

Half-Moon Cookies and Black-and-Whites Are Cousins, Not Twins

Although the terms are often used interchangeably, half-moon cookies and New York City’s black-and-white cookies are distinct styles.

Half-moons usually start with a soft, rounded cake base, often in vanilla or chocolate, and are frosted with buttercream-style icing, while black-and-whites more typically use a flatter, denser shortbread-like base topped with firm fondant.

Food writers point out that these differences in texture and icing reflect separate bakery traditions that evolved in upstate New York and in Manhattan. 

Immigrant Bakeries Shaped the Two-Color Cookie Tradition

The two-toned iced cookie is tied to immigrant baking in New York State. German immigrant bakers in Manhattan are credited with popularizing the black-and-white cookie in the early 1900s, while a Swedish-American family later steered the half-moon style to local fame in Utica.

This blending of European techniques with American ingredients helped cement the half-moon and black-and-white as classic examples of how immigrant bakeries influenced regional American desserts.  

The “Half-Moon” Look Comes From Cake Science

The characteristic dome on many half-moon cookies is the result of a cake-like batter that has more liquid and leavening than typical drop cookies.

When baked, this batter rises quickly and sets into a rounded top that provides a soft, tender crumb. That shape not only holds generous layers of chocolate and vanilla icing but also helps keep the interior moist, which is one reason these cookies can feel more like miniature cakes than standard cookies.  

Why Half-Moons Use Two Different Icings

Bakers often use two different formulations on half-moon cookies: a cocoa-enriched icing on one side and a vanilla or milk-based icing on the other.

The chocolate half frequently relies on cocoa powder rather than melted chocolate so it sets firmly at room temperature, while the vanilla side may contain more powdered sugar and dairy for a creamier texture.

This contrast in fat and sugar ratios allows both icings to firm up without running together, preserving the crisp visual split between light and dark.  

Black-and-White Cookies Became a Symbol of New York City

Over time, the black-and-white cookie, closely related to the half-moon, became a culinary icon of New York City, appearing in delis, bakeries, and popular culture.

Food writers and tour guides often highlight it as a “quintessential New York treat,” and by the late 20th century, it was featured in television, travel pieces, and food columns as shorthand for the city’s deli culture and ethnic bakery heritage.  

Half-Moon Cookies Reflect Changing American Dessert Preferences 

The popularity of half-moon and black-and-white cookies in the 20th century mirrored a broader American shift toward “portable cake” desserts sold in single servings at bakeries and lunch counters.

Instead of buying whole layer cakes, customers could enjoy an individual treat with a soft cake crumb and rich icing, which fit the faster-paced, urban lifestyles emerging in cities like New York and Utica. This trend helped solidify frosted cake-like cookies as a staple in American bakery cases.
