Step 1: Prepare the oven

Preheat the oven to 175°C (350°F). Line two baking sheets with parchment paper.

Step 2: Combine the dry ingredients

In a medium bowl, whisk together the flour, baking soda, and salt until evenly combined. Set aside.

Step 3: Cream the butter and sugars

In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar for 2–3 minutes until light and fluffy.

Step 4: Add the eggs and vanilla

Beat in the eggs one at a time, mixing well after each addition. Add the vanilla extract and mix until smooth.

Step 5: Make the cookie dough

Gradually add the dry ingredients to the butter mixture. Mix on low speed or stir with a spatula until just combined. Avoid overmixing. Fold in the chocolate chips.

Step 6: Chill the dough

Cover the dough and refrigerate for 30 minutes. Chilling helps prevent excessive spreading and develops a richer cookie flavor.

Step 7: Shape the cookies

Scoop approximately 1½ tablespoons of dough for each cookie. Place the dough balls on the prepared baking sheets, leaving about 2 inches between them.

Step 8: Bake

Bake for 10–12 minutes, or until the edges are lightly golden and the centers still look slightly soft. Do not wait for the centers to become completely firm, as the cookies will continue to set while cooling.

Step 9: Cool and decorate

Let the cookies rest on the baking sheet for 5 minutes before transferring them to a wire rack. Sprinkle with a little flaky sea salt if desired.
