Sweet Apple Turnovers

1 refrigerated pie crust
2 tart apples (Granny Smith, Winesap), peeled, finely chopped (about 1 1/2 C)
1/3 C packed brown sugar
1/2 tsp ground cinnamon
1 egg, beaten
4 tsp butter or margarine
2 Tbsp milk, divided
2 Tbsp sugar

Roll pie crust into a 10-inch square on lightly floured surface. Cut into sixteen 2 1/2" squares. Combine apples, brown sugar, cinnamon and egg in large bowl; toss to mix. Preheat oven to 425. Place pastry squares on ungreased baking sheet. Spoon 1 tablespoon apple mixture onto each square. Dot each square with 1/4 teaspoon butter. Fold each pastry over filling to form a triangle; brush pastry edges with some milk and press to seal. Brush pastry tops with remaining milk and sprinkle with sugar. Bake until golden brown, about 10 minutes.
