01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - Whisk together the all-purpose flour, baking soda, and fine sea salt in a medium bowl until evenly mixed.
03 - In a large bowl, beat the softened unsalted butter, granulated sugar, and light brown sugar using an electric mixer or whisk until creamy and light, about 2 to 3 minutes.
04 - Add the eggs one at a time to the creamed mixture, mixing well after each addition. Stir in the pure vanilla extract.
05 - Gradually add the dry ingredient mixture to the wet ingredients, stirring gently until just combined to avoid overmixing.
06 - Evenly fold the semisweet chocolate chunks into the dough using a spatula.
07 - Drop dough onto the prepared baking sheets using a tablespoon or cookie scoop, spacing each portion about 2 inches apart to allow for spreading.
08 - Bake the cookies for 11 to 13 minutes, until the edges are golden but the centers remain soft.
09 - Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
