Preheat your oven to 375°F (190°C). Line two baking sheets with parchment paper or silicone mats.

In a large mixing bowl, cream the butter with granulated and brown sugar on medium speed for 2-3 minutes until light and fluffy.

Add eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

In a separate bowl, whisk together flour, baking soda, and salt. Gradually add to the wet ingredients until just combined.

Gently fold in the chocolate chips and walnuts until evenly distributed.

Scoop about 2 tablespoons of dough onto the prepared baking sheets, spacing 2 inches apart. Bake for 8-10 minutes or until edges are golden.

Let the cookies cool on the sheets for 5 minutes before transferring to a wire rack to cool completely.
