Equipment

  • mixing bowl Large since it is a big batch recipe
  • Electric mixer or stand mixer
  • measuring cups
  • measuring spoons
  • baking sheet 11 x 13 jelly roll style pan
  • parchment paper

Ingredients
  

  • 1 cup butter
  • 1½ cups white sugar
  • 1½ cups brown sugar dark or light
  • 42 oz creamy peanut butter not natural peanut butter
  • 1½ tsp vanilla
  • 6 eggs
  • 4 tsp baking soda
  • 6 cups oats Instant oats work best, but rolled are okay.
  • 2 cups all-purpose flour
  • 2 cups M & M's
  • 2 cups chocolate chips semi-sweet

Instructions
 

  • Preheat oven to 350 °F
  • In a large bowl or stand mixer combine the sugars and butter. Mix well until smooth.
  • Add in the eggs, vanilla and peanut butter. Cream together well.
  • Combine the flour, oats and baking soda with the creamed mixture.
  • Add the M & M's and chocolate chips and stir those in until evenly mixed.
  • Shape the cookie dough into one to one and a half inch balls and place on a parchment lined baking sheet about 2 inches apart.
  • Bake in the 350 degree oven for 10-12 minutes. Do not over bake.
  • Enjoy fresh and warm, store in airtight container for 5 days or freeze in ziplock bag for up to 3 months.

Notes

    • Use creamy peanut butter that is no stir. Natural peanut butter will not make the cookies turn out as well.
    • Which oats to use? Rolled oats do work, however they make for a cookie that can crumble a little easier. Quick oats would be recommended for this recipe.
    • Mix with an electric mixer or a large stand up mixer. With this cookie being a larger batch recipe, using a mixer works well.
    • Use butter not coconut oil or olive oil. Butter has the best taste and consistency for this cookie recipe.
    • These cookies can either be frozen as the dough balls and baked later or baked and frozen. Store them in a ziplock bag or airtight container for up to 3 months.
    • If this recipe is too much in volume, feel free to cut the recipe in half.
