Pre-heat oven to 350 degrees and line two baking sheets with silicone baking mats or spray with cooking spray.
In a medium bowl, whisk together dry ingredients (oats through salt) and set aside.
In another medium bowl, whisk together wet ingredients (eggs through vanilla) and slowly stir into the dry ingredients.
Scrape down the sides of the bowl with a rubber spatula to make sure everything is evenly incorporated then stir in the chopped walnuts.
Drop by tablespoons or a large cookie scoop two inches apart on the prepared baking sheets. Bake for 10 minutes then let cool completely on a cooling rack before serving.
