Preheat oven to 350° F.
For the crust: In a mixing bowl, cut butter into flour; stir in egg and water. Form into a ball and chill dough. Roll out into two 12- to 14-inch circles, about 1/4 inch thick.
For the filling: In a mixing bowl, combine the peaches, sugar, flour and lemon juice. Divide and place half the filling in the center of each pastry circle. Fold pastry over peaches and seal using a fork to crimp edges. Using a knife tip, cut a few steam vents into top of each pastry. Lightly brush pastry with cream and sprinkle with sugar. Place on a parchment-lined baking sheet and bake for 25 minutes, or until pastry has browned. Remove from oven and cool.
