I'm not sure how long the doors had been open, but when I arrived at Bogart's Doughnut Co. at 7:02 this morning, there were five people in line ahead of me, and six drool-worthy varieties of doughnuts were filling the cases stretching under an elegant white marble counter.

Owner Anne Rucker appeared from around the corner, a tray lined with vanilla bean cream-filled doughnuts in her arms. The woman in front of me recognized her and said what we were all thinking.

"I've been driving by every day this week, hoping to see that you were open," she said with a laugh. She had her Walker residence employee name badge hanging around her neck – it's located a few blocks to the south – and she told Rucker, "Welcome to the neighborhood. We'll all be coming over. A lot."

Shoppers at the Kingfield Farmers Market will recognize Rucker, an attorney who has followed her passion for baking, first with a popular market stand she calls Bogart Loves (from her middle name, and her grandmother's maiden name) and now this tiny, gleaming white doughnuts-and-coffee shop at 36th and Bryant in south Minneapolis.

Like all great doughnut shops, I smelled the goodness long before I walked in the door. Rucker's trademark brioche doughnuts, glistening with sugar and the very definition of fried-dough perfection, were filled with Nutella or a vanilla bean cream, or smeared in glazes, either brown butter or vanilla bean. Cake doughnuts were either lavender-scented or done up in rich chocolate. Prices run $2 (for the cake doughnuts and the glazed brioche doughnuts) and $3 (for the filled brioche doughnuts).

Rucker is trying to open quietly – a near-impossibility in today's social media world – with a grand opening scheduled for Friday. Doors stay open, "until we run out," she said. That was around noon on Wednesday, her first unofficial day of business.
