1. Preheat oven to 350-degrees

For the Crust:

1. Line the bottom of a 9-inch Springform or tart pan with removable bottom with parchment. Oil sides of pan with coconut oil.
2. Combine dry crust ingredients in a bowl and whisk until well combined. Whisk maple syrup and coconut in another bowl and add to dry ingredients. Mixture should combine into a nice ball. If too dry, add some water, one teaspoon at a time. If too wet, add a little more oat flour.
3. Press crust into the bottom of the pan and up the sides.

For the Filling:

1. Mix all filling ingredients in a large bowl until apples are evenly coated. Pour into crust.
2. Cover pan with parchment and then foil and place on a baking tray. Bake 45 minutes or until apples begin to soften.

For the Streusel Topping:

1. Meanwhile, make the streusel by mixing dry ingredients well in a bowl, then adding wet ingredients and stirring until well combined.
2. Remove parchment and foil from the pie and put back in the oven for 45 minutes, adding streusel to top of pie half-way through. Cover with foil if browning too quickly. Pie is done once apples are soft and crust is a deep golden-brown.
3. Remove from oven and allow to cool completely before slicing and serving with coconut whip (see notes), if desired.
