Add the peanut butter, apple sauce, vanilla extract, and coconut sugar to a bowl. Beat well with a mixer until well combined.
Slowly mix in the oat flour and baking soda into the bowl with a rubber spatula.
Fold in the chocolate chips gently with the rubber spatula to disburse into the cookie dough.
Use a large cookie scoop to scoop the cookie dough balls on a cookie sheet lined with parchment paper for easy clean up.
Bake the cookies until the edges are just turning golden brown and then take them out of the oven.
