Preheat your oven to 375°F (190°C). Line baking sheets with parchment paper or silicone baking mats.
In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
In a large bowl, using an electric mixer, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Beat in the vanilla extract and then the eggs, one at a time, until well combined.
Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix.
Stir in the Nestle semi-sweet chocolate chips and chopped nuts (if using) by hand.
Drop rounded tablespoons of dough onto the prepared baking sheets, about 2 inches apart.
Bake for 9 to 11 minutes, or until the edges are golden brown and the centers are still slightly soft.
Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
