Black and white cookie

I read somewhere last week a lament that no one had told the writer about the special magic of the black and white cookie. I, too, lament. Jonesing for a snack last week, I remembered this person’s rave about the b&w and purchased one at the bodega on the way home. Whoa, what a dessert! The black and white cookie is, in fact, not a cookie but a flat, thinly frosted cake, like someone has sat on a cupcake. Cookie convenience, cupcake taste. I am hooked.

Being the last person in NYC to learn about this biracial delectable, I need some help in locating the best b&w in the city. New Yorkers, where do you get your black and white cookies?
