Instructions
Filling
Fill a large pot halfway with water and bring to a boil. Fill a large bowl with ice water and set aside. Add peaches to boiling water and blanch for one minute. Remove peaches from pot to stop cooking using a large slotted spoon and carefully place peaches in bowl of ice water. Peel and remove pits. Cut peaches into one inch pieces.
Preheat oven to 350°F. Lightly grease a 8 inch cast iron skillet or a 2 quart baking dish.
Mix all of the filling ingredients together in a large bowl, then spread into the baking pan. Bake for 10 minutes. Remove from the oven and set aside as you prepare the topping.
Topping
Whisk the flour, sugar, baking powder, baking soda, and salt together in a large bowl. Using a cheese grater, grate the butter directly into the bowl. Using a pastry cutter, cut in the cold grated butter until the mixture resembles coarse pea-sized crumbs.
Pour in the buttermilk and gently mix until evenly combined. Dough should be slightly sticky once completely combined. If the dough is dry, add more buttermilk, a tablespoon at a time.
Assembly
Gently flatten out handfuls of dough. Place flattened pieces of dough over the peach filling.
To make the egg wash, beat egg white with milk or buttermilk in a small bowl. Brush the top of the biscuit dough with the egg wash.
Combine cinnamon and sugar in a small bowl and sprinkle mixture on top of the egg wash.
Bake
Bake for 35-45 minutes, or until the biscuit topping is golden brown and peach filling is bubbling around the edges.
Remove cobbler from the oven and set the pan on a wire rack. Cool for 5 minutes before serving. Serve warm with vanilla ice cream or whipped cream.
Cover and store left cobbler in the refrigerator for up to five days. Before serving, reheat cobbler in a 275°F oven until warm and bubbly and biscuit topping is crisp. Cooked peach cobbler can also be frozen for up to three months. Thaw overnight in the refrigerator and warm in the oven before serving.
