In a mixing bowl, paddle your tempered butter until smooth. Make sure to paddle just until smooth. You do not want to whip and aerate the butter.
Add your sugars and mix until there are no longer any streaks of butter. Add your vanilla and eggs, incorporating one at a time. Scrape down the sides and bottom of the bowl.
Add the sifted flour, salt, and baking soda in two additions. Scrape down the bowl in between additions.
Add the cocoa nibs and chocolate in two additions.
Scoop out the cookies to your desired size. Top with a sprinkle of maldon and additional chocolate if you please. Line a sheet pan with parchment and spray with a light layer of cooking spray to prevent sticking. I had my cookies at 2 ounces each and it will bake at 350F for 15 minutes. The edges of the cookie should be slightly brown but still soft in the center. Let the cookies cool on the sheet for a few minutes before transferring it to a cooling rack.
