Who else loves a Monster Cookie?

What’s not to love about a peanut butter oatmeal cookie with lots of chocolate chips and M&Ms?  (Feel free to substitute your favorite nut or seed butter by the way!)

We started with our favorite Peanut Butter Cookies, which are a long time family recipe… made some tweaks and added some gluten-free oats, chocolate chips & M&Ms.

And they are a total hit!

Best part? The are super easy to make and are made with pantry staples, except for the M&Ms which I happened to have picked up while stocking up on essentials at the store the other week.

All you need is ….

butter or dairy free butter

brown sugar

cane sugar

vanilla extract

eggs (I haven’t made them with flax eggs but provide my recommendation)

peanut butter

gluten-free flour (we used GF Jules)

baking soda

gluten-free baking powder

a pinch of salt

gluten-free oats

chocolate chips

M&Ms (or a similar brand chocolate candies)

A note about oats: Oats are a naturally gluten-free grain but they are contaminated via cross contact with wheat, barley and rye during the growing and processing process.  So definitely look for gluten free oats, preferably certified gluten free oats.

But there’s more.… back when my son was first diagnosed with celiac disease, gluten-free oats were mostly grown via a process known as purity protocol.  In recent years, gluten-free oats have also been processed through a manufacturing process known as “sorting”.  There is much controversy about sorting versus purity protocol oats.  And some oats that were thought to be “safe” were recently tested to show gluten… For more information I’m linking to articles by Gluten-Free Watchdog from January 2023 and April 2023.

Back to the Gluten-Free Monster Cookies…

They are super easy to whip up!

Using a hand mixer or stand mixer (we love our Kitchen Aid-amazon affiliate link, as you know!) or even mixing by hand, beat the butter, sugar and vanilla.

Then beat in the eggs and peanut butter.

Add in the flour.

Then the oats. Then stir in the chips and M&Ms leaving some aside for topping if desired.

Roll into balls, press down gently and top with the extra m&ms and extra chips if you like.

The entire process takes 15 minutes or less!

Bake for just 10 minutes and enjoy!

Ingredients

  • ¾ cup butter or dairy-free butter, softened (1 ½ sticks )
  • 1 cup brown sugar, packed
  • cup granulated sugar
  • 2 teaspoons vanilla extract
  • 2 large eggs room temperature
  • ¾ cup peanut butter or nut/ seed butter of choice I use natural peanut butter, not from the bottom of the jar if possible.
  • cups gluten-free all purpose flour with xanthum gum* We used GF Jules flour
  • teaspoon baking soda
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • cups gluten-free oats
  • ¾ cup semi-sweet chocolate chips of choice
  • ¾ cup plain M&Ms or candy of choice plus more for topping a desired

Instructions

  • Preheat oven to 350 degrees F and line 2 baking sheets with parchment paper. Set aside.
  • Using a stand mixer or hand mixer, mix butter, sugars and vanilla until well combined and creamy.
  • Add eggs and beat thoroughly.
  • Beat in peanut butter.
  • In a separate small bowl, add flour, baking soda, baking powder and salt. Mix with a fork or pastry cutter. Then add the flour mixture to the creamed mixture and mix until combined.
  • Add in oats and mix till combined.
  • Add in chocolate chips and m&ms and gently mix till just combined.
  • Roll batter into balls and place on prepared baking sheets. Press down gently and top with the extra m&ms and extra chips as desired. For thicker cookies, don't flatten but still top with extra m&ms!
  • Bake for 9-12 minutes, or until golden. You do not want to over-bake. In my oven, I bake the first batch for 10-11 minutes, subsequent batches for 9 -10 minutes.
  • Let cool on the baking pan for 10 minutes, and enjoy!
  • Store in an air tight container for up to 5 days. Or freeze for up to 3 months.

    These cookies are to die for! I have already baked them twice in three days! My mom said that they are the best cookies she has ever had… and she eats a lot of cookies!!!

    1. Yes, if you are not following a gluten-free diet, these should work fine with regular all purpose flour! They are based on my family’s peanut butter cookie which was not originally gluten-free. Let me know if you make them!

    Oh My Gosh!! Those cookies! This recipe!
    simple easy to do soooo yummy …

    we made a bunch of those last week-end. it was a great mother-daughter time.
    she’s 8 and she’s just crazy about those monster cookies.

    we made few adaptation: grated coco instead of oats and french smarties candy instead of m&m’s.
    Peanut Butter was soooo mandatory 🙂

    thank you so much for sharing all those recipes.

    I made these cookies for the first time today and they tasted amazing! My husband who usually isn’t a fan of gluten free cookies said he that he couldn’t even tell a difference! Win for me, means I don’t have to eat the whole batch myself? 10/10 recommend!

  4. Amazing!!! We love these cookies. My kids say they smell like peanut butter but don’t have an overwhelming taste of peanut butter. I had a bag of M&M baking chips to use and this was perfect. The softness of these is incredible. I have to stop eating them all!

  5. 5 stars
