Preheat the oven to 350°F. Line a baking sheet with parchment paper.

Make the crust. In a large bowl whisk together the oat flour and salt. Add the nut butter and maple syrup and use a fork to incorporate. Add the water and mix until a dough forms.

Place the dough in between two sheets of parchment paper roll into a 12" circle (the circle doesn't have to be perfect). Set aside.

In a small bowl mix the maple syrup, cinnamon, nutmeg, and salt.

Peel (if desired) and core the apples. Cut the apples in half then slice very thinly. Fan them out slightly.

Arrange the apples in the center of the crust, leaving a 1-1.5" border. For best visual results try to arrange the apples "randomly" and fill in any empty spaces with smaller apple pieces.

Brush the apples liberally with the maple syrup mixture.

Fold in the sides of the crust. If any part of the crust breaks, just press it back together.In a small bowl, whisk together the soy milk and agave to create a vegan egg wash.

Brush any exposed dough with egg wash and sprinkle with sugar.

Bake for 30-40 minutes, until the crust is golden brown and the apples are soft.

Let cool briefly, then serve immediately. Enjoy with ice cream!
