Step 1

Whisk flour, 2 tablespoons sugar, baking powder and salt in a medium bowl. Using 2 forks or a pastry cutter, cut in butter until the mixture looks like coarse cornmeal. Add milk; stir until evenly moistened.

Step 2

Place the dough on a lightly floured work surface; knead until it forms a smooth ball, about 1 minute. Cut the dough into 12 equal portions and roll each into a ball.

Step 3

Cover the bottom of an air fryer basket with parchment. Combine cinnamon and the remaining 1/3 cup sugar in a medium bowl. Roll 6 of the dough balls in the cinnamon sugar and place in the air fryer basket. Cook at 350 degrees F until browned and puffed, 7 to 8 minutes. Gently remove from the basket. Repeat the process with the remaining dough.
