In a food processor, combine the almond flour, coconut flour, sea salt, and sweetener. Pulse briefly to mix.
Add the cold butter or coconut oil and pulse until the mixture resembles coarse crumbs – about 8-10 pulses. Don't overprocess.
Add the egg and vanilla, then pulse just until the dough comes together. If it's too dry, add 1-2 teaspoons of cold water.
Form the dough into a ball, then flatten into a disc. Wrap in parchment paper or plastic wrap and refrigerate for at least 15 minutes.
Peel, core, and slice the apples into approximately ¼-inch thick slices. In a large bowl, toss the apple slices with lemon juice.
In a separate bowl, combine the sweetener, arrowroot starch, cinnamon, nutmeg, ginger, cloves, and salt. Sprinkle this mixture over the apples, add the vanilla, and toss until evenly coated.
Let the filling sit for 10 minutes after mixing to allow the apples to release some juices.
Preheat your oven to 350°F (175°C).
Place the chilled dough between two pieces of parchment paper and roll to about ¼-inch thickness.
Transfer the rolled dough to a 9-inch pie dish using the parchment paper to help. Gently press it into the dish and repair any tears by pressing the dough together with your fingers.
Pour the apple filling into the crust. You can create a simple lattice top with the remaining dough, opt for decorative cutouts, or crumble the remaining dough over the top for a streusel-like topping.
If desired, brush the crust lightly with a beaten egg for a golden finish, and sprinkle with a little extra cinnamon and sweetener.
Bake for 45-50 minutes, until the crust is golden brown and the filling is bubbling. If the edges start to brown too quickly, cover them with foil or a pie shield.
Allow the pie to cool for at least 10 minutes before serving for the perfect texture.
