Preheat oven to 300°F and line a large baking pan with parchment paper and set aside. Cream the butter, sugar, and brown sugar together in the bowl of a stand mixer fitted with a paddle attachment on medium speed for about 2 minutes.

With the mixer on low speed, add the flour mixture to the butter mixture and continue mixing for about 45 seconds. Don’t overmix! Stir in chocolate chips and walnuts by hand with a rubber spatula, do not use a mixer. Portion dough with a large cookie scoop (about 3 tablespoons) onto the prepared baking sheet about 2 inches apart.

Over 30 Million of these cookies are enjoyed each year! This recipe doesn’t make that many, I got 20 huge cookies with a large cookies scoop! I baked half and froze half for later!
