Preheat the 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.

Beat in the eggs one at a time, then stir in the vanilla and milk.

Gradually blend the dry ingredients into the wet mixture.

Fold in chocolate chips and nuts if using.

Drop rounded tablespoons of dough onto ungreased baking sheets.

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

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