Gluten Free Monster Cookies

I was going to say these don’t taste gluten-free but then I stopped and thought, what does that even mean?

These Gluten Free Monster Cookies just taste like peanut butter monster cookies. The end.

Gluten Free Monster Cookies are full of peanut butter, gluten free oats, and candy. No one will miss the gluten!

Kidding. That wasn’t the end. You didn’t really think it would be, did you? #Italktoomuch #allthetime

{Really, I do. You should see the look on my husband’s face when I try and have another conversation about Annie with him. Or about blogging. The eyes glaze over. Kind of like when he talks to me about football.}

So I made you gluten free cookies today. Are you happy? I hope so. But really? They’re just cookies. Nothing to be scared of. They don’t even have any weird secret ingredients.

You see, before Christmas, a flyer came home from the room mom at school. Jordan’s teacher filled out a “what I like” form so we could get her gifts she liked. All was fine and dandy until I got to the bottom of the paper:

“I try to eat gluten free” it said.

Is there a worse sentence for a dessert, gluten-loving blogger? All thoughts of brownies and cookies and every single treat I was going to make flew out of my head. What would I give her teacher???????

Then I decided to make gluten free monster cookies. Because, peanut butter, obviously. It was a good decision.

Gluten Free Monster Cookies are full of peanut butter, gluten free oats, and candy. No one will miss the gluten!

I’ve never made monster cookies before, but Ashton has…in several forms. From scouring through her posts it turns out that monster cookies are pretty much peanut butter cookies with oats, M&Ms, and sometimes raisins. That’s when inspiration hit.

This peanut butter cookie is naturally gluten free, at it’s base. So is this one. It’s all the same recipe, the easy one: peanut butter, sugar, and an egg. I use brown sugar and granulated sugar, and I add some baking soda, and the cookies are fabulous. No flour = good peanut butter cookie.

So then, to round out the monster part of the program, we needed oats. And before you get all “but oatmeal isn’t gluten free!!!” on me, some brands are. Bob’s Red Mill has a brand of it that are rolled oats, and Chex has a brand that is quick oats. I used the Chex brand. If you’re using old fashioned oats, I suggest you give them a whirl for a few seconds in a blender or food processor to turn them into quick oats.

Because you’re adding some extra dryness to the peanut butter cookie recipe, you need to add a little more moistener. I used some nonfat milk. I checked, and it was gluten free. I only added M&Ms to these cookies, but you could be a rebel and add raisins if you like that sort of thing.


See? Making gluten-free isn’t that hard…when you leave the flour out all together, that is. 😉

Gluten Free Monster Cookies

These monster cookies are made with no flour and gluten-free oats so they are a good cookie for everyone!


  • 1 cup creamy peanut butter (I use Skippy)
  • 1 large egg
  • 1/2 cup packed brown sugar
  • 1/2 cup granulated sugar
  • 1/2 teaspoon vanilla extract
  • 1/2 teaspoon baking soda
  • 1 teaspoon nonfat milk
  • 1/2 cup gluten-free oats (or substitute regular quick cooking oats)
  • 1/2 cup M&Ms or a combination of M&Ms and raisins


  1. Preheat oven to 350°F. Line a cookie sheet with a silpat baking mat or parchment paper
  2. Sitr peanut butter, egg, and sugars together until smooth. Stir in vanilla, baking soda, milk, and oats. Stir in M&Ms and/or raisins.
  3. Scoop 2 tablespoon cookie dough balls onto prepared cookie sheet. Use a lightly dampened fork to flatten slightly in a criss cross pattern. (These cookies will not spread much.)
  4. Bake for 8-11 minutes, until they no longer look glossy and are slightly browned on the bottoms. Cool before storing in an airtight container for up to 4 days. Note: these cookies are more crumbly than regular cookies, so be careful when stacking or transporting.


Not all gluten free oats are quick cook oats. To make them quick cook, just give them a few pulses in a food processor or blender to break them up a bit. There are two brands of GF oats that I know of, Bob’s Red Mill (rolled oats) and Gluten Free Chex (quick cook).

  1. I love using oats because then the cookies don’t spread and there’s no chill time!
    And this recipe is fantastic. Way to go for baking for Jordan’s teacher! I’m a teacher and I always appreciate baked goods when they come my way!

  2. Love that you baked these as GF and that you were doing so to be kind to a teacher and accommodate her nice of you!

  3. Mmm! I am gluten free, so I am used to converting “normal” recipes into gluten free ones, but it sure is nice to have the work done for me! And monster cookies— that is one thing I have been meaning to try, but never got around to (I have never had one!). Thanks!

  4. These cookies look so awesome! It’s great that they are versatile for different diets. (& I’m the complete opposite – I don’t talk enough 😉 )

  5. These cookies look amazing, Dorothy! I’ve never had a gluten free monster kind before, so I’m in awe of this. All of that peanut butter is just calling my name! Pinned!

  6. Thanks for this!  I know so many people who are gluten free these days and I never know what to bake.  These are perfect!!

  7. I rarely bake GF stuff too and am usually at a loss when I do try to make something. There is a skating mom at the rink who is GF, and I’m sure she’d love these!

  8. These are gluten free?  I love how chewy they look, and I love that you added the oats.  Pinned.

  9. Love these! I must say gluten-free scares the heck out of me, but these definitely don’t seem scary!

  10. I say it every day, but you’re so funny! Love reading your posts. You know the only problem with this? I would not even get these baked, I love cookie dough more than anything, my boys do too, and peanut butter, are you kidding me? Not a chance, but we’ll love eating the dough!! 😉

  11. You come over to my place and I’ll give you my most recent GF muffin fail from the freezer and then you’ll know what “Gluten Free” tastes like! lol! 

    ps- please bring these cookies! They look AMAZING! Pinned! 

  12. Yum, these cookies made me crave cookies! Love it. And yeah, I don’t even know how gluten-free taste-like, but I sure do know how a good cookies taste. 

  13. What a great GF recipe! I like anything with peanut butter (…and chocolate…and sugar)! By the way, I feel the same way about football (eyeroll)!

  14. Planning to make these for a friend who’s birthday is this weekend. Are they chewy & soft or are they crunchy?

    • They’re soft and crunchy. Does that make sense? They’re not a traditional soft and chewy cookie, more to the crunchy side, but they do have a softness to them, depending on you how bake them. But the oats do add some chewiness over a traditional easy PB cookie. Enjoy!

  15. I made flourless peanut butter cookies a couple months ago, but putting m&ms and oats in them too. I need these!

  16. LOL! I only care if it’s gluten free if it doesn’t taste good, then I blame it on the GF fact. If it tastes good, I don’t care what is or is not in it. It’s nice that those with allergies can enjoy it, but for me, it’s about taste!

  17. Mmmm, did you say monster cookies. With or without gluten, these are fantastic!!

  18. I have so many people asking me about gluten free desserts, and I’m always like “huh?” I know what gluten free is, but I play dumb because I’m afraid of turning something I love into something that tastes boring or “eh…” You’ve given me hope!

  19. Never would have guessed in 100 years that they’re gluten-free! Looks delicious!

  20. Just made these last night for my family and they are so yummy!  Thanks for the recipe.

  21. Hahaha!  All I can think of when I hear gluten free is the comedian Jon Pinette.  “I don’t know what gluten is, but it’s delicious!”  He is hilarious!  Go you for making and accommodating the teacher with these awesome looking cookies!  I have to admit I would have been lazy and gotten a gift card 🙂

  22. Monster cookies are my favorite! Can’t resist the peanut butter oat combo!

  23. It was nice of you to go out of your way to make these cookies gluten free for the teacher. I’m sure she was extremely grateful. They look delicious!  You can never go wrong with peanut butter.  

  24. Awesome Dorothy! I love GF OATs, they are readily available and I don’t notice the difference at all. 

  25. Haha, I feel you! My sister-in-law is gluten free and most of my baking is, well, not. However, I always love recipes like this I can store away to make for her whenever she visits! Pinned! Plus, they look gooood. 

  26. Haha, I think it’s hilarious how, just like you, I have to clarify and warn everyone ahead of time that even tho the recipe is gluten free, it seriously DOES NOT taste any different from any other regular cookie! These look absolutely delicious, and I’m sure the teacher appreciated how thoughtful you were to think of her food restrictions! Can’t wait to try out your recipe for myself! 🙂 Yum!

  27. The catch 22 to any free food, is that if you announce it then suddenly your food becomes good, for ____ free food. If you don’t then the people who benefit most might miss it. The picture looks amazing. Like, makes me think that maybe I could handle the gluten free thing, amazing. But then I remember all of the other things that I like that have gluten and decide that it’s not so bad after all. This is a great GF recipe to have on hand. It seems like every day I learn someone is GF.

  28. What a fabulous cookie! I need to make these for my family soon!

  29. These look so great, Dorothy, and I love that they’re packed with nut butter and oats!  Pinned. 🙂

  30. OOOH  MY!!! so yummy!!  Hello from the new spanish cooking blog!
