Preheat your oven to 350°F (175°C).
In a bowl, whisk together the flour, baking soda, and salt.
In a separate bowl, cream the softened butter, brown sugar, and granulated sugar until light and fluffy.
Beat in the egg and vanilla extract until combined.
Gradually add the dry ingredients to the wet mixture, mixing until just incorporated.
Fold in the chocolate chips.
Chill the cookie dough for at least 30 minutes.
Drop spoonfuls of dough onto a prepared baking sheet, leaving space in between.
Bake for 10-12 minutes until the edges are golden brown.
Remove from the oven and let cool on the baking sheet for a few minutes before transferring to a wire rack.
