Mix the dry ingredients: In a small bowl, combine the protein, almond flour, cocoa powder, baking powder, and sea salt.
Add wet ingredients: Stir in almond butter, vanilla extract, and almond milk until a thick dough forms. Adjust milk if needed for consistency.
Fold in chocolate chips: Gently mix in the chocolate chips. The dough should be moist and easy to shape.
Shape and bake: Form dough into a cookie and place on the prepared sheet. Bake 8-10 minutes, until edges are set but center is soft.
Cool and enjoy: Let the cookie cool slightly before eating, expect a fudgy center and perfectly melted chocolate.
