Preheat your oven to 350°F (175°C).

In a medium bowl, whisk together the flour and baking soda; set aside.

In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy—about 2-3 minutes.

Add the eggs and vanilla extract, mixing until well combined.

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

Fold in the chocolate chips (and nuts, if using) gently with a spatula.

Drop the dough onto a lined baking sheet using a cookie scoop or tablespoon, leaving ample space between each mound.

Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown but the centers are still soft.

Let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
