Gluten-free Peanut Butter Cookies are crispy, crumbly and full of flavor.
Preheat your oven to 350F and line 2 pans with parchment paper.
In the food processor, process the oats into a flour-like meal. This might take a few minutes.
Do the same with the peanuts but make sure not to over-process or the peanuts will be too oily, just until you have evenly crushed peanuts.
In a bowl of a standing mixer, place the shortening, sugar, peanut butter, egg, and salt, and mix until you get a smooth mixture.
Add the oats and peanuts and mix to combine.
Using a cookie spoon, scoop the cookie dough on the pans, and using the back of a fork, mark each cookie from top to bottom and then from side to side.
Bake for 15-18 minutes or until the cookie is golden on the sides.
