Preheat oven to 375°F. Line cookie sheets with parchment paper.
In a small saucepan over medium heat, brown butter until it turns brown in color and nutty in aroma. Remove from heat. Allow to cool 5 minutes.
In a mixing bowl or mixer, combine brown sugar, oats, egg and vanilla. Gradually add brown butter. Mix until combined.
Stir in salt and flour.
Using a cookie scoop, drop onto a parchment lined cookie sheet leaving ample room to spread. Bake 6 minutes or until golden brown.
Allow cookies to cool on the baking sheet for approximately 5 minutes before removing to a wire rack.
