It’s sweeping Manhattan’s Upper East side. Locals and tourists are lining up for hours to get their hands on a cup of hot cocoa from Glace. You don’t have to take your taste buds to the Big Apple to try it! Recipe creator Amy Richardson brought the buzzy beverage to our own kitchen. Amy recently returned from a trip to New York and got her hands on a cup of her own! She even walked 40 blocks to wait in line. For thick, New York hot chocolate, Amy uses cornstarch and evaporated milk to bring in the thick consistency and a rich flavor.
