Crumbs Bake Shop was a bakery chain headquartered in New York City. Founded in 2003 as a small mom-and-pop style bakery on the Upper West Side of Manhattan by Mia & Jason Bauer, the company expanded to 79 locations in ten states and Washington, D.C. Crumbs was the largest cupcake chain in the United States. It produced more than 50 varieties of gourmet cupcakes. Crumbs reopened on October 14, 2014 at its Broadway location in New York and other locations after a three-month shutdown, and then closed all of its reopened stores permanently in December 2016.
