Preheat your oven to 375°F (190°C). Line baking sheets with parchment paper.
In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
In a large bowl, cream together the softened butter, granulated sugar, brown sugar, and vanilla extract until smooth and creamy.
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.
Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart.
Bake for 9 to 11 minutes, or until the edges are golden brown but the centers are still soft.
Remove from the oven and let the cookies cool on the baking sheets for 5 minutes before transferring them to wire racks to cool completely.
