Preheat oven to 375°F (190°C) and line a baking sheet with parchment paper.

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

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

Beat in the egg and vanilla extract until well combined.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined, then fold in chocolate chips.

Drop spoonfuls of dough onto the prepared baking sheet, spacing them evenly.

Bake for 9-11 minutes, or until the edges are golden brown and the centers are still soft, then cool on a wire rack.
