Yesterday I was having one of those “snacky” days. You know the ones, when you start digging through the pantry looking for something sweet 2 hours after breakfast and then every 20-30 minutes for the rest of the afternoon until you finally give in (and bake something, haha).
I wasn’t trying to make anything specific. It was more like…what do I have, and how quickly can I turn it into a cookie (yes, this is really how my mind works, always cookies)?
I found half a jar of peanut butter, a whole bag of oats, and the usual baking staples. Good enough.
I’ll be honest though, oatmeal cookies don’t always win me over (there I said it). They can be a little dry, a little bland, or just not quite worth the effort. But peanut butter cookies…now that’s a different story.
And these chewy peanut butter oatmeal cookies that I threw today turned out amazing. They’re actually chewy, soft in the middle, a thick enough to sink your teeth into. Just the kind of cookie that keeps you coming back to the cooling rack over and over, haha. Which, on a snacky day, is very important.

Why You’ll Love These Peanut Butter Cookies
These aren’t your typical boring oatmeal cookies, and they’re not the kind of peanut butter cookies that fall apart or leave you reaching for a glass of milk.
They’re chewy, a little textured, and just crisp enough around the edges. The oats give them structure without drying them out, and the peanut butter keeps everything rich without going overboard. The centers stay soft, but still feel like a fully baked cookie (right from your pantry).
If you’ve made my peanut butter oatmeal butterscotch cookies, this is the simpler, everyday version, the one you make when you want a really good chewy peanut butter cookie.
Ingredient Notes
- Use room temperature unsalted butter for these cookies. Room temperature butter is soft but not greasy. If it’s too warm, the cookies will spread like crazy.
- You can use light or dark brown sugar, but I find that dark brown sugar is my go-to because it gives the cookies a deeper, slightly richer flavor and more chew (and the chew is very important an oatmeal cookie in my opinion).
- Only use old-fashioned rolled oats for the best results. They give the cookies structure and that classic oatmeal texture. Quick-cooking oats are pretty small, but you can use them. The cookies will be smoother and less chunky.
- Regular creamy or crunchy peanut butter works best here. Natural peanut butter can make the dough too oily, so I’d avoid using it if possible.
Step-By-Step Instructions
- Preheat oven to 350°F and line 3 baking sheets with parchment paper.
- In a medium bowl, whisk the flour, oats, baking soda, and sea salt together. Set aside.
- In a large bowl, cream the butter, peanut butter, brown sugar, and sugar together with an electric mixer on medium speed for 1–2 minutes, until light and fluffy.
- Add the egg and vanilla and mix just until smooth and combined (about 20–30 seconds).
- Add the dry ingredients and mix with a rubber spatula until just combined. The dough will be soft, fluffy, and a little sticky (this is what we’re going for).
- Let the dough rest for 10–15 minutes to hydrate the oats and improve texture (this step is optional, but totally worth it).
- Using a 2 tablespoon cookie scoop, portion dough onto prepared baking sheets a few inches apart to allow for some spreading.
- Bake one pan at a time in the center of the oven for 10–11 minutes, rotating halfway through. The edges should be set, with the centers still slightly soft when they’re done.
- Let the cookies sit on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Tip
These cookes are very soft when they come out of the oven. If they look wonky after baking, just nudge them back into shape while they’re still warm. Nothing dramatic, just gently work the edges with a spatula or use the cup method to make them round again.
My Baking Sheets
They heat evenly, don’t warp, and give you that golden finish every time. Simple, sturdy, and really good at what they do.
Recipe Tips & Notes
- Don’t overbake these cookies. They’ll look slightly underdone in the center when you pull them out, that’s the goal and what keeps them chewy.
- Use a cookie scoop to scoop the dough. This keeps the cookies uniform in size, so they bake evenly and hold a nice, round shape.
- Don’t overmix the dough. After adding the dry ingredients to the wet, mix until just combined. Overmixing can make the cookies too dense or tough and we want soft, chewy cookies.
- The edges should be set while the centers still look pretty soft, this is the key for that soft, chewy texture. If you overbake them, they’ll be stiff and hard.
- If they spread unevenly, gently nudge the edges back into shape with a spatula or swirl them with a glass or round cutter right after baking.
- The cookies will be very soft and fragile when they first come out of the oven (this is totally normal and what we’re going for). After reshaping them, let them sit on the baking sheet for 5-10 minutes to set up before moving them to cool completely.
- For a a softer cookie that stays that way a little longer, add 1–2 tablespoons of milk to the dough.
- A sprinkle of flaky sea salt on top right out of the oven is never a bad idea.
Storage Recommendations
Store these butterscotch oatmeal cookies in an airtight container at room temperature for 4–5 days. They’ll stay soft and chewy as long as they’re well covered. Add a slice of bread to the container to help keep the cookies soft, it works like magic.
You can freeze the cooled cookies in an airtight container for up to 3 months. Thaw cookies at room temperature before eating. You can also scoop the dough into balls and freeze and bake straight from frozen, adding 1–2 extra minutes to the bake time.

Oh my gosh I just made these for my husband birthday and I’m about to eat all of them❤️ I used crunchy peanut butter and I mixed in a couple tablespoons of cocoa powder. Me and baking don’t always mix but this recipe was perfect❤️
I used crunchy peanut butter because that’s all I had. It worked great – love this recipe.
Oh that’s great to know! I’ve used crunchy peanut butter (or half crunchy, half smooth) in some other recipes, but I haven’t tried this one yet. It’s on the list though. Yum!
The texture of these was amazing. So chewy and delicious.
Woo! Thank you so much, Dannii – that was the goal. Glad to hear you loved them too.
These cookies came out perfectly with just the right balance of peanut flavor and chewiness. Really delicious.

The combination of the oats and the peanut butter in these cookies is literally amazing. The cookies are hearty, loved them.
I love that about these cookies too, Michelle! They’re like an extra-special peanut butter cookie. Or maybe, a wintertime, huskier version LOL!
This made me laugh – huskier! For sure!
I think I also found my new comfort treat! Love the chewy consistency so much, will definitely make more next time!
Thanks so much, Kim! I’m so glad to hear it, we can be comfort treat #twins!

Hey there, just had to drop a quick note to say your peanut butter oatmeal cookies are the real deal. The chewiness is spot-on, and the balance of flavors had me reaching for seconds (and okay, maybe thirds). Your recipe was straightforward and easy to follow, which I appreciate. Seriously, these cookies are a hit!

My wife made these I love them. The recipe is in our favorite file.
Hi Bill! Thank you so much, I’m thrilled to hear you love the cookies too. 🙂
I could not do a taste test. They came out amazing looking. My husband was given two immediately out the oven. He did not like it, to soft,he let the other harden and cool. He enjoyed it. My grandchildren and daughter will do the taste test tomorrow. Iam sure it will be favorable.
Hi Regina! Thank you so much for the feedback on these cookies! I’m glad to hear your husband enjoyed them once they set up and I’m hopeful the grandchildren gobble them up too. 🤞🏻Happy baking!
Came out very good and chewy
Hi Jazmin! Excellent, I’m so glad to hear it. Thanks for taking a minute to leave a review, I appreciate it so much!
Very good recipe. What I really like about it is that it makes a half a recipe. The cookies were delicious and very moist. Definitely a keeper!!
Just made these for breakfast. Don’t judge us……… I was skeptical because the batter looks too loose. No. THEYRE AMAZING
These are a hit! Small batch was eaten quickly. I love the way the recipe is written so that specific ingredient amounts are listed in the action steps.
I had high hopes for this recipe. Followed it to the letter, unsalted butter and 1/2 tsp sea salt, but a quick taste test of the dough was awfully salty. The finished cookies aren’t much better… they’d be great if it wasn’t for the overpowering salt. Are they supposed to taste like that?
I tried again with 1/4 tsp iodized salt, and the cookies came out much better.
How many cookies does this make?
Oh WOW, these are delicious! Nice and chewy with great flavor!
