Preheat oven to 350 degrees then line a half sheet pan with a silpat or parchment paper and set aside. Add almond flour, coconut sugar, tapioca flour, chocolate chips, baking soda, and salt to a medium-sized bowl then whisk with a fork to combine. Add milk, oil, and vanilla then stir until ingredients are well mixed. Scoop dough by the Tablespoon onto prepared sheet pan then barely wet your fingers and press down gently on each dough mound to flatten slightly. Bake for 8-9 minutes or until cookies are light golden brown on top. Let cool for 5 minutes before transferring cookies to a cooling rack to cool completely. Store in an airtight container on the counter for 4-5 days.
