NEW YORK — It’s time to make the money.

Shares of Dunkin’ Brands Group soared nearly 47 percent on Wednesday, their first day of trading, feeding the demand of investors looking to trade in coffee and doughnuts.

Shares closed at $27.85, up $8.85 from the $19 price that Dunkin’ Brands set Tuesday night. Dunkin’ sold about $423 million worth of shares at $19 apiece.

Most stocks get a one-time pop on their first trading day. Still, Dunkin’ Brand’s reception indicates that investors are willing to shell out for initial public offerings.

“There’s more to the IPO market than just the Internet bubble,” said John Fitzgibbon of IPOScoop.com.

Dunkin’ Brands, which owns Dunkin’ Donuts and Baskin-Robbins, has said it will use the money from the public offering to pay down debt, in part so that it will be able expand overseas. Dunkin’ Brands could raise a bit more if the banks underwriting the IPO decide to buy more shares in the next 30 days.

Dunkin’s public offering comes at a time when restaurants are struggling as Americans are cutting back on eating out. But analysts predict that breakfast and snacks will continue to grow over the next decade.

In 2010, Dunkin’ Brands’ revenue grew 7 percent, partly because of new locations but also because more customers are buying more things per visit. However, net income fell 23 percent as expenses rose, including fees paid to the investment firms that own it, costs for refinancing debt, spending on technology, and reserves set aside for potential legal costs.
