Place 1 pie crust in the bottom of your pie dish
Place your peeled, cored and sliced apples on top of bottom pie crust - should be a heaping pile as apples shrink as they cook
Cut second pie crust into strips and make a lattice work top over the apples, finish edges of pie
Melt butter over medium heat in a sauce pan, add flour to melted butter to form a slurry
Stir in white sugar, brown sugar, water and cinnamon - bring to boil, reduce heat and allow to simmer for a few minutes
Add vanilla to warm mixture, stir to combine
Pour hot mixture over pie, crust and all - pour slowly allowing mixture to seep into the apples
Bake in a preheated 425 degree oven for 15 minutes, Reduce oven temperature to 350 degrees and bake for 35-40 more minutes, until apples are soft and crust is golden brown
