Flourless Peanut Butter Oatmeal Chocolate Chunk Cookies
Who needs a cookie? I do.
Apparently it’s September. I dunno.
Honestly, I love fall. It’s my favourite time of year – the warm sun, crunchy leaves, longer nights (besides food, sleep is my favourite), explosion of fruits and veggies, and then the parade of festivities – Thanksgiving, a round of birthdays (including mine), Halloween and Christmas. The only problem with fall is when you realize it’s September first tomorrow and the huge list of things you were sure you’d get done over the expanse of summer that stretched so indulgently before you back in June still remain undone. Especially when that to-do list involved a new kitchen.
I made these out in Tofino this summer, when we had a house full of hungry kids, no flour, very little butter and only one egg. They’re similar to monster cookies, which are traditionally made with peanut butter and oats but no flour (which makes them thin and chewy), and generally topped with Smarties or M&Ms or some such, which would totally be appropriate here if you’re into that sort of thing. I had a big bar of chocolate I had brought up to test some unrelated recipes with, and I knew if I packed it to come back home it would either be eaten in the car or melt en route, or both.
I realize that it’s the eve of back-to-school, and while I’m thinking that W’s lunches will provide a perfect excuse for me to bake batches of these, most kids aren’t allowed to bring nuts to school. (We have no allergies at our school – or haven’t since W was in kindergarten – so I can send all the PB&Js I want – if you can’t use peanuts, almond butter should work fine, or one of those nut-free butters, like Wowbutter or No Nuts Golden Pea Butter, which in my experience works as well as peanut butter.
As I’ve been typing this Mike came in with Snickers, and it occurred to me that they’re similarly chewy/chocolatey/peanutty, and that chopping one into the batter would likely be a Very Good Idea. I’ll give it a go tomorrow morning (I have an office to bring them to this week!) and report back.

Flourless Peanut Butter Oatmeal Chocolate Chunk Cookies

Preheat the oven to 350F.
In a medium bowl, beat or stir together the butter, peanut butter and sugars until creamy and smooth; beat in the egg, vanilla and salt.
Stir in the oats and baking soda, then the chocolate chunks. Drop by the spoonful onto a parchment-lined baking sheet, spacing them well apart (they spread out pretty thin), and bake for 15 minutes, or until spread out and golden. Let them cool for a bit on the baking sheet, then remove them with a thin spatula. Eat them warm.

Would it be possible to freeze these, to bake a few at a time? I love chocolate chip oatmeal cookies but have trouble not eating them all if they are in the house. And I don’t have anyone else to help! Or would it be better to bake them all and then freeze?
Amber – Yes, I’m sure these would freeze just fine! Wrap a few at a time and pop them in the freezer. Or freeze the dough in balls, transfer to a freezer bag, then bake from frozen!
I’d say these would be perfect for back-to-schoolers! And back to workers (ie me!) they look fantastic and I haven’t had cookies in waaaay too long, thanks so much for the recipe! x
can’t wait to try!
I can’t wait to make these. The pics are absolutely mouth watering.
I love how these cookies look! I made pb cookies recently, but I know my husband would like the chocolate version here much better. On my baking agenda!
I just took these out of the oven and they are amazing! Finally a cookie my GF daughter and I can both eat without losing any flavor. I used instant oatmeal (since that was all i had) and mine did not get thin. They are so moist too!
Hey Julie! What brand of chocolate are you using? These look so delish but not grocery store brand?
Thanks!
Please add me to your email list!
These look heavenly! I’m allergic to nuts so I’m going to try sunflower seed butter (even though sometimes that turns things green in the oven (still just as delicious!!!). Thanks Julie!
Who needs a cookie? I think you mean… who DOESN’T need a cookie? I always want cookies. Always. Especially if they sound and look as good as these ones… Yum!
My grandson has nut allergies. We are totally hooked on WOW butter. It is as good, if not better than “PB” I am surprised your school allows PB. Most schools don’t. This recipe of yours sounds delish.
Used WOW Butter. These are ANAZINGLY GOOD!
Most experts don’t expect devices with all the new specification to start out appearing
for that mainstream customer prior to the second half of
2010. I got a new Sony upscaling DVD player and connected it via HDMI, and today my DVD’s look almost as good being a Blu-ray.
The cost is often as little as a few dollars for the used connector cable
to over $5. I’m quite certain they have a streaming only plan for $seven. Rca to hdmi

I added some roasted peanuts to the chocolate chunks…….these are the best cookies!
Thin, crispy and salty. We loved them!
I am not gluten free, but who needs the extra calories from white flour?
These will be my new go to recipe!
Thanks!

Very good post. I definitely appreciate this website. Keepp it up!
These look amazing. Just wondering how many cookies the recipe makes so I know if I should double it? Can’t wait to taste them!
These are delicious!! They are seriously one of my favorite cookies, and I’m not even gluten free! (I actually have an instant dislike, and distrust for anything labled “gluten free”, but have been trying to limit my gluten intake…haha.) Anyway, that being said, these are seriously good! The only thing that I modified was that I substituted the cane sugar (both brown and white) for 1 cup of coconut sugar. My kids gobbled them up, and we now have a new favorite cookie recipe!
Yay! so glad to hear! And I agree with you 100% – this is one of my favourite cookie recipes too!
Did you turn the oats into flour? I didn’t see a single oat flake in your picture. The cookies were delicious. Next time, can I take out 1/4 cup or 1/2 the sugar ? Will that change the cookies
I didn’t turn the oats into flour – they’re whole (maybe quick?) oats. You can almost always reduce the sugar in a cookie recipe – just do it bit by bit and they should work fine.
Thanks
Thank you so much for this recipe! I added some different/extra ingredients! 🙂 I didn’t have a half cup of almond butter left so I used 1 banana and a little more than 1/4 cup almond butter. Also added 1 tbsp of Chia seeds. Instead of butter I used coconut oil and had some giradelli milk chocolate chips on hand which were used. Also only used in total 1/4 cup of cane sugar/light brown sugar. DEElicious, complimented our yummy dinner greatly 😉
So good to hear Natasha!
These are by far the best cookies! Completely addicted to them and now one of my favorites:) i did reduve the butter and sugar by half of whats called for and still turned out delicious. …. everyone make these cookies.
The best element is, you won’t even be able to tell the difference between your beats and beats made in real recording studios.
A lot of engineering producers start out as either mixing engineers or assistant engineers to record
label producers. Or, you could pay them a nominal fee for their trouble.
How much peanut butter? I do not see it listed in the recipe
Thanks
Strange, I see it there! should be 1/2 cup.
Hello Julie,
I do not see (Not visible) the beginning ingredients listed on your flourless oatmeal choc chip & pB cookies. (Seems cut off) What I see starts with vanilla…please tell me how much to use for sugars, egg, PB, & butter
Thanks so much,
Nora
I love these cookies!!
The website does not have the ENTIRE LOST OF INGREDIENTS for the flourless oatmeal, choc chip peanut butter cookies- Can you please provide it?
I think this may be a glitch when viewing on an iPhone… the list should be complete!
Love the look of these cookies. I made a batch but the mixture is so crumbly. Is it supposed to be that way? I tried baking it and they do not spread. I followed the recipe exactly. I may add just a little bit of liquid. Would love to hear from you when you get a chance to let me know what I might have done wrong.
Interesting… what kind of peanut butter did you use?
Smucker’s natural PB, the kind you have to stir then refrigerate.
I Warmed it in the microwave first and let it sit to room temp
yeah natural peanut butter can be dry…
If natural PB turns out dry, wouldn’t Almond butter be the same??
I made them today and they came out delicious…
eek where did the actual recipe go??
I’ve made these several times and love them….went to make a double batch today…and unless I’m loosing it…the actual recipe is no longer in the post (opened it on both an ipad and a laptop)
Can it bring it back pretty please?
Thank you!!
Thank you thank you!
Made these this afternoon… ate 4 while waiting for the second batch to come out of the oven. So SO good! Thank you for the recipe.
So glad to hear it!!!
