In a cup, combine the flour and water, then mix until smooth and set it aside.
Next, grab a large mixing bowl and add the peaches, butter, sugar, vanilla extract, lemon juice, cinnamon, nutmeg, and ginger. Fold the ingredients, the put everything into a large pot. Place the pot over medium-high heat.
As everything heats up, stir well and let the butter melt completely. Once melted, pour in the flour and water mixture. Keep stirring so everything blends smoothly, then let it cook for about 5 more minutes until slightly thickened.
Meanwhile, open up one of the boxes of pie crust/ dough and roll out and cut them into squares. Arrange those squares in a greased 9x13 baking dish, making sure the bottom is nicely covered.
Bake the pie dough squares at 350°F for 8 minutes(This gives it a head start and keeps it from turning soggy later)
Next, remove it from the oven and carefully pour the hot peach filling right over the crust.
Open open the second box of pie crust and roll both crust/dough on top. Make sure the whole cobbler is covered with dough. For extra flavor and that golden finish, brush a little of the leftover cobbler filling over the top crust.
Return the dish to the oven and bake at 350°F for 40–50 minutes, or until the top turns golden brown and the filling bubbles up beautifully.
Remove the crust from the oven, and let it cool down for a few minutes.
Serve and enjoy by itself or with ice cream.
