The world’s largest donut chain has long sold itself as a pit stop.

“America runs on Dunkin’,” goes the company’s slogan, and its customers typically stop in for a pre-work sugar-and-caffeine jolt and then split.

Now, in an effort to get customers to stick around and visit after the morning rush, Dunkin’ Brands Group has set in motion a cafe-style store redesign. With its earth tones and jazz soundtrack, the new look echoes Starbucks, which has long provided a place for people to hang, sip coffee and surf the Web.

Since a July 2011 IPO, Dunkin’ shares have more than doubled. They rose 1.2 percent to $41.42 at the close in New York. Dunkin’ is trading at a 4.7 percent premium to Starbucks on a price-to-earnings basis.
