In a saucepan over medium heat, melt 1 cup of unsalted butter until golden brown, about 5-7 minutes.

In the mixing bowl, add 3/4 cup of brown sugar and 1/2 cup of granulated sugar to the browned butter and mix until smooth.

Add 1 whole egg and 1 yolk, beating until combined and slightly frothy.

Whisk together 2 cups of flour, 1 teaspoon of baking soda, and 1/2 teaspoon of salt, then gradually add to the wet mixture.

Fold in 1 to 2 cups of chocolate chips until evenly distributed.

Chill the dough for at least 30 minutes, preferably overnight.

Preheat your oven to 350°F and scoop dough onto a lined baking sheet, baking for 11-13 minutes.

Cool on the pan for 5 minutes before transferring to a wire rack.
