In a food processor, process the oats until they are like a powder. In a little saucepan, melt the butter until it is bubbly. Then remove it from the heat along with all the browned bits.
In a mixing bowl, add the sugars to the browned butter and beat with a hand whisk, then add the egg and the vanilla and continue whisking.
Then add the oats, sieve the flour and add that too along with the baking soda and salt.
Mix in the dry ingredients and then the chopped chocolate. Chill the dough for a minimum of an hour before baking. I like to weigh my cookies, if you do so you will get 12 cookies of 36g each.
Bake them on a baking tray, in a preheated oven, for about 8-10 minutes.
