Say what you want about the tasty warmth of its fresh-from-the-fryers glazed confections, Krispy Kreme Doughnuts (NYSE: KKD) hasn't been leading the sweet life of late. Beleaguered and beaten down in the midst of what CNN Money calls a "sputtering turnaround effort," the company remains challenged with an anemic share price, struggling sales, and folding franchise locations.

Today, Chief Executive Daryl Brewster, who took the reins in March 2006, announced plans to retire for personal reasons. Brewster will leave his post at the end of this month. The board quickly named James Morgan, board member since 2000 and chairman of the board since 2005, to take the vacated seat.

In other news, Krispy Kreme has followed the lead of many fast-food concerns to announce that all products sold in the U.S. are now free of trans fats. KKD officials said it has been introducing zero-grams trans fat products across the country during the past several months.

Investors are cheering this combination of news, as the stock has spiked 9.5% in today's trading. Of course, given the stock's current price (around the $3 level), this represents an absolute increase of 27 cents per share.
