Preheat the oven to 350?F (175?C).

In a mixing bowl, whisk together the flour, baking soda, and salt.

In another bowl, cream the softened butter, brown sugar, and granulated sugar until light and fluffy.

Add the egg and vanilla extract to the butter mixture and mix until combined.

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

Stir in the milk and chocolate chips until evenly distributed.

Drop spoonfuls of dough onto a baking sheet lined with parchment paper.

Bake for 10-12 minutes or until the edges are lightly golden.

Allow cookies to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
