I'm looking for a bakery that sells chocolate kugelhopf (also spelled "guglhupf") - and I don't mean with chocolate chunks - this has a dark (?) chocolate swirled into the cake. This is a rarely-seen variation. Traditional kugelhopf (a German/Alsatian brioche) is usually made with raisins or currants. There was a bakery in Yorkville that used to sell it - now long closed. Can anyone help? Manhattan is preferred but I'll travel to the outer boros or beyond, if necessary (or mail order).
