Step 1

Preheat oven to 325ºF. Coat a mini (2-inch) doughnut pan with cooking spray.* In a bowl combine flour, baking soda, and salt. In another bowl combine the next five ingredients (through vanilla), whisking until smooth. Add yogurt mixture to flour mixture; whisk until combined and smooth.

Step 2

Spoon batter into a large resealable plastic bag. Using scissors, cut off a corner; squeeze batter into prepared pan, filling each cup about two-thirds full. Smooth tops.

Step 3

Bake about 8 minutes or until doughnuts are nearly firm when lightly pressed. Cool in pan on a wire rack 3 minutes. Turn doughnuts out of pan onto wire rack.

Step 4

In a bowl stir together granulated sugar and cinnamon. Dip warm doughnuts into sugar mixture, turning to coat.
