Adding sea salt to your chocolate chunk cookies will create an addicting sweet and savory delight.
Beat butter, brown sugar, sugar, and powdered sugar until light and fluffy, 3-4 minutes. Add egg yolks, egg, and vanilla. Beat, occasionally scraping down the sides of the bowl, until mixture is pale and fluffy, about 5 minutes. Slowly add dry ingredients, mixing just to blend. Using a spatula, fold in chocolate.
