Directions
Preheat the over to 375ºF [190ºC]. Line two baking sheets with parchment paper.
In a medium bowl, combine the flour, baking soda, and salt. Set aside.
In a large bowl, with a hand mixer, beat together the butter, granulated sugar until light and smooth, about 3 minutes. Beat in the eggs and vanilla until smooth. Gradually stir in the flour mixture until combined. Fold in the chocolate chips and the walnuts (if using). Drop the dough by rounded tablespoonful onto the prepared baking sheets, leaving 2 in [5 cm] between the cookies; the cookies will spread as they bake.
Bake for 7 to 9 minutes, or until golden brown around the edges. Transfer the cookies to a wire rack to cool. Store in an airtight container at room temperature for up to 1 week.
