In a large mixing bowl, combine your flour(s), protein powder (if using it), cocoa powder, salt and granulated sweetener and set aside.
In a microwave safe bowl or stovetop, melt your nut butter with the maple syrup. Once combined together, whisk your mint extract (or vanilla extract) before pouring into the dry mixture.
Mix together until a crumbly texture remains. Using a tablespoon, add milk of choice until a thick batter is formed. Add half the chocolate chips, reserving the rest to top the cookies. If batter is too thin, add an extra spoonful of flour. If it's too thick, add a dash more milk.
Using your hands, form into small balls and place on a large plate or cookie sheet. Press each ball into a cookie shape, topping with a few chocolate chips. Refrigerate for at least 10 minutes, or until firm.
* Adjust accordingly- If your protein powder isn't sweetened, you may need more. ** Adjust accordingly- Depending on what protein powder/coconut flour you use, you may need considerably more than you think! These cookies are best kept refrigerated, but taste amazing slightly thawed from the freezer. For a super fudgy cookie, enjoy at room temperature.
