Hummel Hummel Bake Shop is a family bakery in East Northport, best known for its original Pizza Crumb, a flat crumb cake built on a Danish bottom and sold ready to enjoy. Founded in 1968 by German-trained baker Grandpa John, the shop passed to his son Derek and daughter-in-law Susan in 1998, who continue baking fresh Pizza Crumbs and traditional baked goods daily.
