Preheat oven to 180 degrees celsius. Line and grease a roasting tray.
In a saucepan melt butter over medium heat, and begin whisking. Stir as it bubbles for roughly 2 mins until butter begins to brown.Take off heat and set aside. ( be sure to watch this carefully as it can easily burn)
In a bowl mix the baking soda, salt and oat flour. Using an electric mixer beat the butter, coconut sugar for roughly 1 min. Slowly add the vanilla and egg. Beat in the oat flour mixture, and lastly stir in chocolate chips. ( If you do not have an electric mixer you can just mix all ingredients into a bowl with a wooden spoon)
Roll mixture into balls and place on the tray. Press down using fork forming a cookie shape
Bake in the oven until golden brown ( takes between 10-12 mins).
Allow to cool slightly before storing!
