Crumbl Cookies opened its doors this week at Rockville’s Federal Plaza, offering a rotating menu of fresh-baked treats for delivery and curbside pickup. Co-owner Mark Sumsion, a franchisee for the Utah-based chain, says this will be the first of several Crumbl stores in Maryland. “We started with Rockville because it has so much diversity, there’s a robust amount of shopping on the Pike, and we love being next to stores like Trader Joe’s, T.J. Maxx and Ross,” he says. Cookie prices range from $3.88 for a single to $34.88 for a dozen, along with side orders of milk and ice cream. The store currently offers delivery in a five-mile range via DoorDash, but Sumsion says he’ll soon expand the delivery area with a staff of dedicated drivers. So what’s the next frontier for Crumbl? Likely Gaithersburg or Germantown.
