Mix together peanut butter, sugar, eggs, vanilla and salt until creamy and smooth. Stir in coconut flour to be sure that is fully incorporated. Dough will be soft and very sticky.
Drop tablespoon sized mounds of dough, 2 inches apart on cookie sheet lined with parchment paper. Bake at 375 for about 14 minutes.
Allow to cool about 5 minutes before removing the cookies off the cookie sheet onto a cooling rake.
