In a large mixing bowl, beat together softened butter, granulated sugar, and dark brown sugar until light and fluffy, about 2-3 minutes. Add eggs one at a time, beating well after each addition. Stir in vanilla extract. In a separate bowl, whisk together flour, baking soda, ground cinnamon, and salt. Gradually add the dry ingredients to the butter-sugar mixture, mixing on low speed until just combined. Gently fold in chopped apples and walnuts.
