Roll out onto floured surface using the other 1/4 cup flour.

Preheat Air Fryer at 325*. Spray Air Fryer with noncook spray.
Cook 1 empanada at a time in Air Fryer at 325* for 8-10 minutes. Flip over and cook for another 5-7 minutes. (Due to differences in altitude, brands of flour, etc you may need to cook for longer or shorter periods in time. Keep that in mind if yours are too doughy or crispy.)
