Heat the butter in a medium sauce pan over medium heat. It will melt and become foamy for a few minutes. Then, the milk solids will caramelize, turning the butter brown. Stir the butter regularly throughout the 10 to 12 minute process and remove it from the heat once it browns because it can burn quickly.Combine the two sugars in a mixing bowl. Once the butter has browned, whisk it into the sugars, then stir in the eggs and vanilla.In a separate bowl, whisk together the flour, salt and baking soda. Dump the dry ingredients into the sugar, butter mixture and use a rubber spatula to just combine it, but don't over mix. Add in the chocolate chips and mix until incorporated into the dough. Preheat the oven to 350 degrees. Line a baking pan with parchment or a silicone baking mat. Use a 1 ounce ice cream scoop to scoop uniform balls of dough and arrange them on the pan. Bake for 10 minutes. Allow the cookies to cool a few minutes on the pan before transferring them because they will be extremely soft right out of the oven. Finish cooling on a wire rack. Keep stored in an airtight container.
