Black and white cookie

Black-and-white cookies, half-and-half cookies, and half-moon cookies are round cookies iced or frosted in two colors, with one half vanilla and the other chocolate. They are found in the Northeastern United States and Florida. Black-and-white cookies are flat, have fondant or sometimes royal icing on a dense cake base, and are common in the New York metropolitan area. Half-moon cookies are slightly dome-shaped (convex), have frosting on a fluffy angel cake base, and are common in Central New York and Boston, Massachusetts. The Amerikaner is a similar cookie in German baking.
