Begin by preheating the oven to 350° Fahrenheit, and line a baking sheet with parchment paper.
Next, cream the butter and brown sugar substitute in a stand mixer or with a hand mixer until smooth.
Add the almond flour, protein, salt, maple, and vanilla. Mix together until well incorporated and you have a smooth dough.
Add the pecans and mix again until the pecans have been broken up and evenly distributed throughout the dough.
Roll the cookies out in 1 1/2 - 2 in circles, place on a cookie sheet, and flatten with the palm of your hand until about 3/4 of an inch thick.
Bake for 9-12 minutes or until the edges have just started to brown.
Let the cookies cool slightly before serving, and enjoy!
