In a large mixing bowl, add flour and butter.
Use a fork or pastry cutter to mix the butter into the flour until you have a crumbly mixture.
Add ¼ cup ice cold water and mix gently with your hands until you have a ball of dough.
If dough is dry, add 1 teaspoon of cold water at a time and mix until you have a ball of dough.
Wrap dough in plastic wrap and refrigerate for 4 hours or preferably overnight.
Sprinkle flour on your countertop and roll out the dough.
Spread the dough gently on a 9 inch pie dish.
Use your hands to press it evenly along the sides and bottom.
Cut off excess dough along the sides with a knife.
Crimp the edges or decorate with a fork like I did.
Add pie filling and bake according to your pie recipe instructions.
