Here is how to make McDonald's Apple Pies:

INGREDIENTS

For the dough:

1 package pastry dough, preferably Pillsbury
1 egg white
1/2 teaspoon cinnamon
1/4 teaspoon sugar

For the filling:

3 Granny Smith apples, peeled, cored, and cut into 1/2-inch cubes
1 tablespoon sugar
1 teaspoon cinnamon
2 tablespoons unsalted butter
2 tablespoons water
1 tablespoon flour

DIRECTIONS

For the dough:

Divide the pastry dough in 2 pieces. Roll one piece out to ¼ an inch thick and roll the other piece to 1/8 an inch thick. Cut both pieces into two so you have four pieces total.

For the filling:

Heat a large saucepan over medium heat and add the butter, sugar, and cinnamon. Stir well and add the apples. Cook until the apples are just mushy, about 10 minutes. Remove the pan from the heat and set aside to cool.

Preheat the oven to 375 degrees.

Once the apples have cooled, add the mixture to the 1/4 inch pieces of pie crust. Top each pie with the 1/8 inch pieces and crimp the edges using your fingers, making sure not to use a fork. Make three to four slits across the tops of the pies. Spray (or sprinkle) the pies with water to moisten the dough a little more before they cook.

Place in over for 20-30 minutes until they are golden brown and fragrant.
