Begin by creaming together 1 cup of chilled butter with ¾ cup of granulated sugar and ¾ cup of brown sugar in a large mixing bowl using an electric mixer on medium speed for 2-3 minutes.

Beat in one room-temperature egg until fully integrated.

In a separate bowl, whisk together 2 ¼ cups of all-purpose flour, 1 teaspoon of baking soda, and ½ teaspoon of salt.

Gradually mix the dry ingredients into the wet mixture using a spatula until just combined.

Fold in 2 cups of semi-sweet chocolate chips into the cookie dough.

Cover the bowl with plastic wrap and chill the dough in the refrigerator for at least 30 minutes.

Preheat your oven to 350°F (175°C) while the dough is chilling.

Line your baking sheets with parchment paper.

Drop rounded blobs of dough onto the sheets, leaving about 2 inches of space between each.

Bake in the preheated oven for 10-12 minutes.

Let the cookies cool on the baking sheets for 5 minutes before transferring them to wire racks.
