Preheat oven to 400 degrees, and line a large baking sheet with parchment paper (or two smaller baking sheets with parchment paper). Set aside.
On a well floured surface, roll each pie dough out into a large circle, about 1/8”-1/4” thick. Using a 3.5” circular cookie cutter (or biscuit cutter), cut out as many circles as you can. If needed, roll out the scraps of dough and cut out more circles. This recipe makes about 12 hand pies, so you need to cut out 24 circles.
Place 12 pie dough circles on your baking sheets, leaving a bit room in between each.
Divide filling evenly between the 12 pie doughs (it’ll be about 2 Tbsp in each).
Place 1-2 small cubes of butter on the filling.
Brush the edges of each pie dough with a little egg wash (this will help the top pie crust adhere to the bottom crust).
Place the remaining 12 pie dough circles on top of the filling. Using a fork, crimp the edges of the pies together.
With a sharp knife, cut slits in the top of each pie (this helps the pie ventilate as it bakes).
Brush the tops and sides with egg wash. Sprinkle with raw sugar, if desired.
Bake for about 28-30 minutes, or until the tops are golden brown and the filling is bubbling.
Allow to cool for a few minutes.
