Preheat the oven to 350°F and line a baking sheet with parchment paper and set aside.
Place the butter in a medium microwave-safe bowl and heat in 30 second increments on high until it's melted. Whisk in the brown sugar, vanilla and egg until no streaks of yellow from the eggs are left.
Add the dry ingredients including, oat flour, baking soda and salt to the wet ingredients and stir with a rubber spatula until combined.
Fold in the chocolate chips. Cover the dough and chill it in the fridge for at least 1 hour or up to 3 days. If you're like me and forget about this step and need them quickly, place the dough in the freezer to shorten the chill time.
Scoop the chilled cookie dough out onto a baking sheet using a medium cookie scoop, or a heaping tablespoon, land bake in the pre-heated oven for 8-10 minutes. Allow the cookies to cool on the pan for 2-3 minutes then carefully transfer them to a wire cooling rack to cool completely.
