Preheat your oven to 350°F (175°C).

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

In another bowl, cream together the softened butter, granulated sugar, and brown sugar until smooth.

Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract and milk.

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

Fold in the chocolate chips if using.

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

Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden.

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