Preheat oven to 350°F (175°C) and line baking sheets with parchment paper.

In a large bowl, cream together the butter, brown sugar, and granulated sugar until light and fluffy.

Beat in the eggs one at a time, then stir in vanilla extract.

In a separate bowl, whisk flour, baking soda, baking powder, and salt.

Slowly fold dry ingredients into wet mixture until just combined.

Stir in chocolate chips until evenly distributed.

Scoop large dough balls (about ¼ cup each) and place 2 inches apart on baking sheet.

Bake for 12–14 minutes, until edges are golden but centers are soft.

Sprinkle with flaky sea salt if desired.

Let cookies cool for 5 minutes on the tray before transferring to a wire rack.
