Gluten-Free Monster Cookies

A few months ago when my parents came to visit my mom made us a big batch of monster cookies.

I couldn’t believe how delicious they were… especially because they were flourless!

I asked her for the recipe and altered it a bit.

For some reason hers came out a tad bit flat and fell apart, not that I minded… I gobbled them up in just a few days! I mean what’s not to love about peanut butter, oats, chocolate chips and M&M’s?!

Some my adjustments included adding quick cooking oats to help “glue” the cookies together, an extra egg yolk to create a thicker/chewier cookie, slightly less butter to prevent them from spreading, and letting the dough chill to allow the oats to absorb some moisture.

All of my little tricks worked- they came out looking beautiful and tasting just as good as the ones she made 🙂 I seriously would make these cookies on a daily basis if I could, they’re that amazing!!!

Happy gluten-free baking!

Ingredients

  • 2 1/4 cups old-fashioned oats *
  • 1/4 cup quick cooking oats
  • 1/2 cup sugar
  • 1/2 cup brown sugar
  • 1 egg + 1 egg yolk
  • 1/3 cup (¾ stick) butter - room temperature
  • 3/4 cup creamy peanut butter
  • 1 tsp baking soda
  • pinch of salt
  • 3/4 tsp vanilla
  • 1/2 cup chocoalte M&Ms
  • 1/2 cup chocolate chips
  • 1/2 cup peanut butter chips

Instructions

  • Line baking sheets with parchment paper or Silpat mats, set aside.
  • In the bowl of a stand mixer, cream butter, peanut butter and sugars until light and fluffy, about 2-3 minutes. Add vanilla. With mixing speed on low, add one egg at a time, mixing until incorporated.
  • In a medium size mixing bowl, combine oats, baking soda and salt. Whisk together. With mixing speed on low, add dry ingredients, mix until combined. Remove bowl from stand and fold in M&Ms, chocolate chips and peanut butter chips. Place dough in the refrigerator to chill for 1 hour.
  • Remove dough from refrigerator and allow to stand at room temperature for 10 minutes. Meanwhile, preheat oven to 350 degrees. Scoop cookies onto the prepared sheets using a standard size scoop, gently pat down to slightly flatten. Place in oven and bake for 10-12 minutes (they will look soft) before removing from oven. Allow to cool on sheets for 3 minutes before carefully transferring to a wire rack to cool completely.

NOTES

* Please make sure that your oats are gluten-free. Bob’s Red Mill Oats are gluten-free, Quaker Oats are not guaranteed to be gluten-free.
-DO NOT SKIP parchment or a mat… seriously, it really is a key part to making these cookies bake perfectly! Also be gentle with the cookies when you are transferring them to the rack to cool, they will probably break apart a little, but just push them back together and let them cool for a good hour or so and they’ll be firm and sturdy!

    1. Hi Christy! I generally use unsalted just because most recipes call for added salt. But if you prefer a them to be a little more salty, go ahead and use salted! Enjoy!
