Preheat oven to 375 F. Mix the almond flour, tapioca starch, and coconut sugar together in a food processor, stand-mixer, or large mixing bowl. Then add the coconut oil, cold water, and vanilla and mix to incorporate.
2 cups almond flour, 1 cup tapioca flour, 2 tablespoon coconut sugar, 4 tablespoon coconut oil, 1 teaspoon vanilla, 4 - 5 tablespoon ice cold water
Roll out the dough onto a large piece of parchment paper sprinkled with a little extra tapioca starch to about ¼ inch in thickness. Place a 9-inch cake pan over top and lightly press down to create an indentation (use this as your guide when adding your filling).
Slice the apples into thin pieces. Fan out the apples into a large circle outlining the circle indentation moving clockwise. Create a smaller circle with the apples moving counter-clockwise inside of the large circle.
2 - 3 apples
In a separate bowl, whisk together the coconut sugar, bourbon, cinnamon, and nutmeg. Drizzle over top of the apples. Use the back of the spoon to brush the mixture into any bare areas.
¼ cup coconut sugar, 2 tablespoon bourbon, 1 teaspoon cinnamon, ½ teaspoon nutmeg
Use the parchment paper to help fold up the sides of the dough towards the middle. Make little "pleats" with the dough every couple of inches by tucking the dough on top of itself to create a large circle.
Sprinkle the crust with a little extra sugar and bake for 25 - 30 minutes until the crust is golden brown.
Top the galette with a couple scoops of ice cream and serve.
