In a large bowl, whisk the melted butter with the brown and white sugar until smooth and glossy.

Beat in the eggs and vanilla until the mixture looks silky.

In a separate bowl, stir together the flour, baking soda, and salt.

Add the dry ingredients to the wet and mix just until combined. Don't overwork it, the magic lives in that slightly messy dough.

Fold in the chocolate chips.

Chill the dough for 30 minutes (worth it, trust me).

Scoop into balls and space them well on a lined tray. Bake at 375°F (190°C) for 9 to 11 minutes, until the edges are golden but the centers still look soft.

Let them cool on the tray for 5 minutes to finish setting, then move to a rack.
