Oatmeal Peanut Butter Monster Cookies . . . loaded with chocolate chips, M&M’s, peanut butter, and oats, these cookies are absolutely incredible!
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!
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

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.
