01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together the all-purpose flour, baking soda, and fine sea salt.
03 - Using an electric mixer or whisk, beat the softened butter, granulated sugar, and brown sugar until creamy and light, about 2 minutes.
04 - Add the eggs one at a time, beating well after each addition. Stir in the pure vanilla extract.
05 - Gradually add the dry ingredient mixture to the wet ingredients, mixing until just combined to avoid overmixing.
06 - Gently fold in the semisweet chocolate chips or chopped chocolate until evenly distributed throughout the dough.
07 - Scoop tablespoon-sized balls of dough onto the prepared baking sheets, spacing them approximately 2 inches apart.
08 - Sprinkle each cookie dough ball with a small pinch of flaky sea salt to enhance flavor contrast.
09 - Bake for 10 to 12 minutes, until the edges turn golden and the centers are set but still soft.
10 - Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool fully.
