Preheat oven to 350 degrees F.
To make the crust:
Place oat flour and nut butter in a bowl and mash with a fork until crumbly. Add water one tablespoon at a time and blend in with the fork until dough is moist enough to roll out. Roll 1/2 of the dough out between two pieces of wax paper and place in a pie plate. Bake for 10 minutes before filling.
Roll out remaining dough to be used for top crust.
To make the filling:
Slice 6 of the apples, place in a bowl and toss with 2 tablespoons of the lemon juice.
Combine
cinnamon, nutmeg and allspice.
Place the remaining 2 apples, 1 tablespoon of the lemon juice, dates and 1 teaspoon of the spice mixture in a high-powered blender and blend until smooth. Fold into the sliced apples. Sprinkle with remaining spice mixture.
Place filling in the prebaked bottom crust. Put top crust on top, brush with non-dairy milk and bake for 25 minutes. Remove from oven, brush again, and bake for an additional 15-20 minutes, until lightly browned.
Sprinkle with additional cinnamon.
Note: You can purchase oat flour at most large supermarkets or health food stores or make it yourself by processing old-fashioned oats in a food processor until finely ground.
