Besides chocolate babka, black and white cookies are the only baked good I really associate with New York (both due more to Seinfeld than ever having eaten either.) And now, it's not that simple to grab one at a deli and nosh. I'd have to track down a vegan version of the cookie (they must exist somewhere...right?)
OR I could turn to (who else but) Isa Moskowitz. Along with Terry Hope Romero (who has NOT relocated out of the city, AHEM) the two created a vegan version of black and white cookies, which you can find in Vegan Cookies Invade Your Cookie Jar!
The ingredient list is pretty basic. I only had a bit of trouble with the dough - it is a thick dough, but not as thick as I would have imagined. They spread out a bit on the baking sheets, making a huge freaking cookie!
Okay, so, a confession, though. I bought chocolate chips to melt to add to the icing for the chocolate side but we don't have a double boiler here and I didn't want it TOO sweet. So for the chocolate side, I just added some cocoa powder. Plus adding hot water to chocolate sounds like it would ruin the texture (and the recipe does state that it gets much thicker) so I just opted for the easier and more uniform icing. Sorry. May the NYC bakery gods strike me down. If you take the easy route out too, I'd recommend Dutch cocoa for a more chocolate-y flavor.
Another note about the recipe: you definitely need parchment paper with these. The cookie itself is pretty delicate and cakey and VERY difficult to get off the sheet in one piece, even having greased the sheet (I only had parchment paper enough for one, so half the half&half batch is a little more battered than the other.) Other than that, easy! I was dubious of the lemon flavoring in the cookie with chocolate but it's delicate and nice.
Abby, when should I send out the delivery?
