Place the flour and baking soda into a bowl and whisk together
Place the butter and both white and light brown sugars into the bowl of a stand mix and beat until light and fluffy.
Add in the egg, vanilla extract and salt and beat until combined.
Stir in both the oats and chocolate chips until well distributed. Cover and chill for a minimum of one hour.
Line two baking trays with parchment paper. I used a medium ice cream scoop to scoop our equal amounts of the dough which i then rolled into balls between the palms of my hands and pressed down onto the baking trays leaving plenty of room between each cookie to allow for spreading during baking.
Preheat the oven to 375f and bake the cookies for around 10 minutes. The edges should be golden but the cookies soft.
Allow to cool for five minutes on the baking trays before transferring to a wire rack to cool completely.
