2 cups oat flour (made from rolled oats in the food processor)
1/4 cup tapioca flour (you can replace with any other flour, but tapioca flour improves crumbly texture)
Instructions
Preheat oven to 325º
Line two cookie sheets with parchment paper.
Cream the peanut butter for 2-3 minutes, preferably with a stand mixer.
Add the milk and continue mixing on low.
Add the flour 1/2 cup at a time just until mixed.
Turn out onto a parchment lined surface to roll out.
Roll out half the dough and cut out your cookies. You will want to use a simple shape for this recipe as shortbread dough is crumbly and finicky by nature.
Bake at 325º for 15 minutes or until just starting to turn golden around the edges.
