One and one-half tsps ground cinnamon
One and one-fourth cup flour
One-fourth cup whole milk
Two tbsps sugar plus one/third cup, divided
Four tablespoons cold butter, cut into small pieces
Three-fourth tsps baking powder
One-fourth tsps salt
1Whisk flour, baking powder, 2 tbsps sugar, and salt in a bowl. Using 2 forks, cut in butter until the mixture looks like coarse cornmeal. Put milk; stir until evenly moistened.
2 Put dough on a lightly floured urface; knead until forming a ball, about 1 minute. Cut dough into a dozen equal portions. Roll each into a ball.
3Cover the bottom of an air fryer basket with parchment. Combine cinnamon and one-third cup sugar in a bowl. Roll six of the dough balls in the cinnamon sugar and place in the air fryer basket. Cook at 350 degrees F until browned and puffed, seven to eight minutes. Remove from the basket. Repeat, with the remaining dough.
