When Oprah's producer called Moveable Feast last October and said Oprah wanted to feature their deeply fudgey brownies, owners Kim and Matt Lennert were ecstatic, but also concerned that their loyal, local customers might suffer.

Before the show aired, the Lennerts set up a mail-order business and erected a tent in the yard to sell brownies until they could secure some additional space, hire more people and set up a call center.

"Personally, I worked from the day we got that phone call until New Years' without a day off, and through the holidays," Matt said. "We were quite overwhelmed."

Although sometimes, Matt admitted, keeping up with the demand felt like an overwhelming burden, he said "if we could do it all over again we would."
