My grandparents used to buy the best chocolate rugelach from a bakery in/around Flatbush. They were definitely a pastry dough, with chocolate drizzled and hardened on top, with some powdered sugar. I have no idea what the bakery's name was, or if it's even still around. Any places in New York that make this kind of rugelach? They were deliciously flaky and crunchy - not soft and chewy like so many rugelach around now . . .
