Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.

Whisk together the flour, baking soda, and salt in a mixing bowl.

In a separate bowl, cream together the butter, brown sugar, and granulated sugar until light and fluffy.

Add the egg and vanilla to the butter-sugar mixture and mix until just combined.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Fold in the chocolate chips with a spatula.

Drop heaping tablespoons of dough onto the prepared baking sheet, spacing about 2 inches apart.

Bake in the preheated oven for 10-12 minutes until golden at the edges and slightly undercooked in the center.

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