It’s no secret that I love cookies. They are one of my very favorite things to make. I am always on the lookout for a great cookie recipe. I usually have frozen cookie dough balls in ziplock bags in the freezer so we can have fresh home baked cookies whenever the craving strikes. Mmm.

 

I got this recipe for Monster Cookies several years ago and it remains a favorite. Every time I share these cookies with family or friends I get rave reviews. They are soft, chewy, and yummy.

They are also good with butterscotch chips in them, but this version is our favorite. Kids love the M&M’s! You can even switch out colors of M&M’s and make them for just about any holiday.

This recipe makes a huge, ginormous batch! If I’m not making them for a large group, I freeze them. I wrap a few together in plastic wrap and then store them in a large ziplock bag in the freezer. They are fantastic heated up in the microwave for a few seconds. Or eaten straight from the freezer. 😉

Another bonus to these cookies is that they don’t call for any flour, so they are perfect for those who have gluten intolerance. My sister can’t eat gluten, so I try to make these yummy cookies whenever we have a family gathering.

Believe me, these cookies are so tasty no one will believe they are gluten free!

My family's favorite oatmeal cookie. Loaded with peanut butter, chocolate chips, and M&M's. Always a hit!

Prep Time 19 minutes
Cook Time 10 minutes
Total Time 29 minutes

Ingredients

  • 1 cup butter or margarine, soft
  • 3 1/4 cups creamy peanut butter
  • 2 1/3 cups brown sugar
  • 1 1/2 cups sugar
  • 1 1/2 tsp corn syrup or honey
  • 1 1/2 tsp vanilla
  • 4 tsp baking soda
  • 2 tsp salt
  • 6 eggs
  • 2-3 cups M&M's
  • 2-3 cups chocolate chips
  • 9 cups old fashioned oats

Instructions

  • Cream butter, peanut butter, sugars, corn syrup, vanilla, soda, and salt in a large mixing bowl till very creamy, 2-3 minutes. Add the eggs and mix well.
  • Stir in M&M's, chocolate chips, and oats till well combined. (Dough will be fairly sticky.)
  • Drop dough by tablespoonfuls onto silicone lined or greased cookie sheets and bake at 350° for 9-10 minutes.
  • Notes

    -There is no mistake, these cookies have no flour.

    -These cookies don't spread as much as traditional cookies, so you can flatten the dough a bit before baking.

    -I find that using old fashioned oats is best, the quick oats make a drier cookie.
