Preheat the oven to 375° Fahrenheit. Line a baking sheet with parchment paper.
In a medium bowl, mix together the freshly diced peaches, lemon juice, ½ cup of the granulated sugar, 1 teaspoon cinnamon, cornstarch, and vanilla.
On a lightly floured surface, roll out one dough disk to about ⅛ inch thick. Cut out circles using a 4-inch cutter.
Place 1 heaping tablespoon of the peach filling in the center of each circle. The less juice the better!
Fold the dough over to create a half-moon shape and press the edges with a fork to seal.
Place the hand pies on the prepared baking sheet. Repeat with the remaining dough and filling.
Mix the remaining sugar and cinnamon. Brush the tops of the hand pies with the beaten egg and sprinkle with cinnamon sugar.
Bake for 20-25 minutes or until the pies are golden brown and the filling is bubbling.
Let cool before serving.
Notes
*I like using Pillsbury Pie Crusts. You can find them in the refrigerated section of the grocery store. If the peaches are difficult to peel, blanch them for about 1 minute in a pan of boiling water. Immediately place them in a bowl of ice water. They should now peel easily.If you have trouble keeping the hand pies sealed, try dipping your finger in a little bit of water and run it around the edge of the circle of dough. Then crimp edges with a fork.
