Preheat oven to 350°. Combine almond flour, coconut flour, coconut oil, vanilla extract, and 2 tbsp maple syrup in a large bowl. Mix and knead together until a solid ball of dough is formed and there are no lumps of coconut oil remaining.
Divide the dough into 6 even portions, and press into 6 greased ramekins, making sure to press the dough up the sides. Bake in preheated oven for 12-13 minutes.
Meanwhile, make the coconut filling. Whip the chilled coconut cream for 2-3 minutes until fluffy using a stand mixer with the whisk attachment or by using a hand mixer. Make sure to use only the solid coconut cream, discard or save the excess liquid from the can.
Add the 3 tbsp maple syrup and coconut extract to the whipped coconut cream and whisk until well combined. Set aside.
Once the crust is done baking, allow to cool about 5 minutes in the fridge. Once cooled, divide the filling into each of the 6 tarts. Top with berries, arranging in an American flag design. Serve within 2 days.
