How to Make It
Remove pie dough from refrigerator; let stand while filling is prepared. Melt butter in a saucepan over medium. Add apples, sugars, and cinnamon; cook, stirring often, until apples are soft and liquid is reduced and thickened, about 8 minutes. Remove from heat, and cool completely.
Unroll pie dough onto a lightly floured surface. Using a 4-inch cutter, cut 8 circles from the dough, re-rolling dough as needed. Lightly roll out each circle a bit more.
Place 1 1/2 to 2 tablespoons filling in center of each dough circle. Brush a small amount of egg on 1 side of the circle, and fold pastry over filling. Crimp edges of pie with a fork. Brush outer surface of pastry very lightly with egg, and sprinkle with 1/4 teaspoon turbinado sugar.
Preheat the air fryer on 390°F for 2 minutes. Add half of the pies to air fryer, and cook 8 minutes, rotating half way through. Repeat with remaining pies. Serve warm.
