Preheat oven to 350 degrees and line baking sheets with parchment paper.
In a very large bowl, mix together the eggs and the sugars. Add the salt, vanilla extract, butter, and peanut butter. Stir in the baking soda and oatmeal, then stir in the M&M’s, chocolate chips, and peanuts.
Drop rounded tablespoons of dough onto the prepared cookie sheets, leaving at least 2 inches between each cookie. Bake for 8–10 minutes, until cookies are set and starting to brown. Do not overbake! Cool on the cookie sheet for 2 minutes before transferring to a cooling rack.
For monster-sized cookies like we make at Vala’s Pumpkin Patch, use an ice cream scoop to drop dough on cookie sheets and press down slightly before baking. Cookies should bake 15–20 minutes.
