Preheat your oven to 375°F (190°C) and line baking sheets with parchment paper.

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

Add the eggs one at a time, mixing well after each, along with the vanilla extract. Beat until smooth and creamy.

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

Fold in the chocolate chips and walnuts, ensuring even distribution.

Drop tablespoons of dough onto prepared baking sheets, leaving 2 inches between each mound. Bake for 8-10 minutes.

Allow cookies to cool on the sheets for 5 minutes, then transfer to a wire rack to cool completely.
