Preheat your oven to 375°F (190°C) and prepare your baking sheets by lining them with parchment paper.

Cream together unsalted butter, granulated sugar, and light brown sugar in a mixing bowl until smooth and fluffy, about 2-3 minutes.

Add a large egg and pure vanilla extract, mixing well until fully incorporated.

Whisk together all-purpose flour, baking soda, and salt in a separate bowl, then gradually blend into the wet ingredients until just combined.

Fold in chocolate chips until evenly distributed throughout the dough.

Scoop tablespoon-sized dough balls onto prepared baking sheets, leaving 2 inches between each ball.

Bake for 10-12 minutes until edges are golden brown and centers look slightly underbaked.

Cool cookies on the baking sheet for about 5 minutes before transferring to a wire rack.
