Preheat your oven to 375°F. Line a sheet pan with parchment paper or grease with oil.
Lightly dust a flat work surface with flour. Divide the dough into 12 equal-sized balls.
Dust the balls of dough with flour to prevent them from sticking. Roll the balls of dough into ⅛ inch thick circles.
Place 2 tablespoons of apple filling on one half of the dough, leaving enough room to fold over and crimp the edges. Fold the empty side of dough over the filling to form half-moons.
Seal well the edges by crimping with your fingers or using the tines of a fork.
Place the empanadas on the lined sheet pan. Using a sharp knife, cut a small X in the top of each packet to allow steam to escape.
Brush the tops and edges of the empanadas with egg white.
In a small bowl, combine the sugar and cinnamon. Sprinkle the sugar mixture on top of each empanada.
Place the pan in the oven and bake until golden brown, approximately 20 to 25 minutes.
Allow the empanadas to cool a bit before serving, or store in a sealed container until ready to eat.
