Preheat the oven to 350°F (175°C) and line a small baking sheet with parchment paper.
In a bowl, mix together the almond flour, gluten-free oats, and baking powder.
Stir in the coconut milk, maple syrup, coconut sugar, and vanilla extract until a thick cookie dough forms.
Divide the dough in half and shape it into two cookies, flattening them slightly as they will not spread much during baking.
Bake for 10-12 minutes, or until the edges are golden brown. Let cool completely before adding the filling.
