Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large bowl, whisk together the almond flour, almond protein, baking soda, and salt.
In a separate bowl, mix the melted coconut oil, maple syrup, vanilla, and apple cider vinegar until well combined.
Add the wet ingredients to the dry ingredients and stir until mostly combined.
Pour in the 3 tablespoons of plant milk and mix until a soft dough forms.
Fold in the chocolate chips.
Scoop tablespoon-sized portions of dough onto the prepared baking sheet. Flatten slightly with your fingers.
Bake for 12-15 minutes, or until the edges are golden and the centers are set.
Let cool on the baking sheet for 5 minutes before transferring to a wire rack.
