Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a medium bowl, combine the almond flour, coconut flour, baking powder, sweetener, and salt.
In a separate bowl, whisk the eggs, melted butter, vanilla extract, and almond milk.
Add the wet ingredients to the dry ingredients and mix until combined. The dough should be thick but sticky.
Shape the dough into 6-8 small biscuits and place them on the baking sheet.
Flatten the tops of each biscuit slightly with your fingers or a spoon.
Bake for 15-18 minutes, or until golden brown. Remove from the oven and let cool slightly.
