Preheat your oven to 350°F (175°C).

In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar until light and fluffy.

Mix in the eggs one at a time and add the vanilla extract.

In another bowl, whisk together the flour, baking soda, and salt.

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

Fold in the rolled oats, chocolate chips, and nuts gently.

Using a cookie scoop or spoon, drop dough balls onto a lined baking sheet about 2 inches apart.

Bake for 12-15 minutes, or until the edges are golden.
