Monster M & M Cookies

Now these aren’t just any kind of cookie. They are MONSTER cookies. Loaded with peanut butter, oats, chocolate chips and M & M’s. These M & M Monster Cookies are a mix between my Chewy Peanut Butter Cookies and Peanut Butter M & M Cookies. They are super thick, chewy and loaded with ton’s of M & M’s and chocolate chips. I slightly under-bake the cookies to get the soft, chewy center.

This recipe makes about 16-18 pretty nice size cookies. I like to double or triple the recipe to have some extra to freeze.

These cookies are the perfect blend of soft and chewy. I love the texture of the old fashioned oats in this cookie.

They are also a great cookie to load up with any leftover halloween candy you still have! I love to mix in mini reese’s cups!

How to make Monster M & M Cookies

Preheat oven to 350 degrees. In a stand mixer with the paddle attachment cream butter and sugar until light and fluffy, about 3 minutes. Add in peanut butter and mix for 1-2 minutes. Add in vanilla and egg. Mix until combined. Combine flour, salt and baking soda in a small bowl. Add the dry ingredients to the batter in two parts with the stand mixer on the lowest speed. Mix for a little less than a minute. Do not over mix. Fold in old fashioned oats, M & M’s and chocolate chips. Portion dough into 16-18 cookies and place on a silicone baking mat on top of a baking sheet. Bake cookies for 11-13 minutes or until lightly golden brown and firm on the edges. Remove from the oven and let set for 3-4 minutes. Transfer to a cooling rack to cool completely.

How long can you store the cookies?

Cookies can be stored in an airtight container at room temperature for 3-5 days (if they last that long). You can always freeze the cookies for up to 3-4 months.

What kind of oats can you use?

I recommend using old fashioned oats. I do not recommend making these cookies with steel cut or instant oats.
