Preheat your oven to 350°F (175°C) and line a large baking sheet with parchment paper.

In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.

In a large mixing bowl, cream together the softened butter, granulated sugar, brown sugar, and vanilla extract until light and fluffy.

Beat in the eggs one at a time, mixing well after each addition.

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

Fold in the chocolate chips and nuts (if using) until evenly distributed.

Scoop the dough onto the prepared baking sheet, forming one large cookie (about 10 inches in diameter) or several smaller cookies, spacing them about 2 inches apart.

Bake in the preheated oven for 15-20 minutes, or until the edges are golden brown and the center is set but still soft.

Remove from the oven and let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
