Mix in order given using mixer. Transfer batter to large container and add the following: 6 more cups quick cooking oatmeal 2 cups Nestle chocolate chips ( I use chocolate and peanut butter chips) 1 medium bag M&M's - these can either be included in the batter or used on top (I mix them into the batter) Mix until well blended.
You should chill the batter for about 1 hour before making the cookies. These cookies can spread out, and it is best to go ahead and chill these to keep them from spreading when the bake. I like to use a 1-ounce cookie scoop to keep the cookies perfectly uniform. Bake at 350 degrees for 10-12 minutes. Freezes well.
