Melt the butter and mix the sugars

• Melt the butter and let it cool slightly.
• Whisk the melted butter with the brown sugar and granulated sugar until smooth and glossy.

Add the egg and vanilla

• Whisk in the egg and vanilla extract until fully combined.

Fold in the dry ingredients

• Add the flour, baking soda and salt.
• Fold with a spatula just until no dry streaks remain, without overmixing.

Stir in the chocolate chips

• Fold in the semi-sweet chocolate chips until evenly distributed.

Scoop the dough

• Scoop large mounds of dough onto a baking tray with a large ice cream scoop, spacing them apart.
• Press a few extra chocolate chips on top of each cookie.

Bake the cookies

• Bake until the edges are golden and crisp while the centers still look slightly underdone.
• Remove from the oven and let the cookies set on the tray.

Finish with sea salt

• Sprinkle the warm cookies with flaky sea salt.
• Let cool until the centers are gooey and set.
