Best Oatmeal Peanut Butter Cookies

When I discovered "Only Oats" had certified gluten-free oats , I was THRILLED!! The thought of being able to eat oats again was exciting... especially my old-time favorite - oatmeal cookies.
(see how to order Only Oats below)

Then to top it all off.. I found this 'normal' recipe for 'normal' people !! All ordinary ingredients found in anyone's kitchen !!

But the cookie is GLUTEN-FREE !!

I have to share it with you !!

(oh.... for those of you who haven't had to learn all this stuff about gluten.... oats is a grain that is gluten-free but the problem is that farmers always rotate crops between wheat and oats which causes cross contamination because some wheat will always come up with the oats and be harvested together - so until Only Oats came to our rescue... oats was on the Celiac forbidden list!)

Oatmeal Peanut Butter Cookies


  • one egg
  • 1/2 cup packed brown sugar
  • 1/2 cup white sugar
  • 1/2 cup butter
  • 3/4 cup peanut butter
  • 1 tsp baking soda
  • 1 tsp vanilla
  • 2 cups oat flakes (Only Oats - gluten-free)

Put all ingredients into the bowl of a heavy-duty mixer and beat until well mixed.

(You may hand mix in 1/2 cup of your own preference of chocolate chips, M&M's, or nuts)

Drop by teaspoon onto cookie sheet and bake at 375' for 15 minutes. Let set for a couple of minutes before removing from pan.

**NOTE-- Only Oats , distrubuted by FarmPure Foods, can be ordered online Canadian or US store here


  1. They look great, Julie! I directed a celiac friend to this blog for your gluten free quesadilla recipe, and I'm sure she'll be happy to find more recipes coming. Thanks!

  2. Julie. . what a great find. . I'll have to look for this oatmeal. ..give me a hint. . where to look.
    The recipe looks very yummy, I love oatmeal and peanut butter.

  3. I found the gluten-free oats here in a local health food store .. It hasn't been out long so if you asked at your local stores and told them who distributes it, they should be able to get it in.

  4. yea!!!!! Great. Thanks Julie! more more grin!

  5. my mom is celiac and a super sensitive celiac at that... do you have any other recipes or good websites to go to.. that would be great!

  6. I am so glad for all celiacs that there are more and more products hitting the market for you! This recipe looks so yummy, Julie!

  7. Julie- those look great! I have to admit cookies are something that I miss the most! I've got a couple great 'sweet' recipes for gluten free treats- when I get a minute to whip them up I'll post them with a picture to share!

  8. thanks so much for your post on my blog.. i will forward the info to my mom!! and look forward to more yummy celiac recipes when you find them!
    God bless

  9. Thanks for another yummy looking gluten free recipe, Julie. We have a celiac in our care group, so I'm always looking for something acceptable to bake.

  10. These cookies are great! My friend and I are eating them right now. We added cinnamon to a few and is adds extra comfort.

  11. I made these for my sister in law who is gf - I now make them for my family as we all love them... I also add white chocolate chips... super tasty!

  12. I tried this recipe because my husband is now on a gluten-free diet and PB cookies are his favourite. Both he and my daughter say that this recipe is better than traditional peanut butter cookies! The only drawback is it can't go to school so I'm going to try it with soy butter and see how it turns out.

  13. Julie when it says oat flakes are they like dried cereal oat flakes to make these cookies?

  14. These loo great and I love oats an peanut butter! I will definitely be making these! Thanks for the recipe!

  15. Hi Julie,
    I have made this recipe twice...they taste delicious...but they always turn into a big sheet of pancake looking things. What would you suggestÉ

  16. Char .. I'm not sure why your cookies are running into each other ...
    I would suggest,
    -not overbeating the dough
    - add more oats than the recipe calls for
    - something that could make the difference is to chill the dough before you bake the cookies ..
    Let me know if that helps !
