These one bowl, peanut butter chocolate chunk oatmeal cookies, are the incredibly peanutty, chocolatey cookie that you’ve been searching for. They’re super easy, require no chill time, and are the perfect cookies to bake up over a snowy weekend at home…or any other day throughout the year. Peanut butter chocolate lovers, this is your cookie!

In stressful times, falling back on the classics is truly one of the best things you can do for yourself. Meaning, if your week has been a difficult one, bake these cookies tonight, and all will be OK again. At least for the 30 minutes it will take you to mix, bake, and sink your teeth into a warm peanutty cookie. Where your head goes after those 30 minutes is fully up to you. But since it’s Friday, my hope is that it’s chill time, and we can all take some time to relax, cook, bake, and enjoy a couple of days off.

Sounds pretty amazing, right? Thank God for Fridays, they’ve always been my favorite day of the week…

On the flip side, no matter how old I get, Sundays will always be my least favorite day. Why? Because as a kid Sunday meant it was back to school the next day. Which meant so much anxiety for me. I may be out of school now, and these days I actually look forward to Mondays, but I can’t shake those Sunday anxiety driven feelings. They occasionally creep up, which is weird, but I’ve kind of just learned to live with it. And to bake cookies to take the edge off! It’s not the perfect solution, but you know, it works.

Which brings me to these perfectly peanutty, oatmeal cookies that are studded with chocolate chunks, and literally melt in your mouth.

Peanut Butter Chocolate Chunk Oatmeal Cookies before baking

I’m sure you guys have noticed, but I don’t have a ton of classic recipes here on HBH. I’m much more about sharing a twist on classics, giving them a bit of a facelift, as some may say. Here’s the truth though, when it comes to desserts, I really love the classics. Especially the classics I grew up eating…chocolate chip cookies, banana bread, peanut bars, and mom’s oatmeal chocolate chip cookies.

I’ve yet to share my go-to chocolate chip cookie recipe. But today I’m finally sharing my go-to peanut butter oatmeal cookie recipe. Although, if you are a vegan, I adore these cookies from last year too. These cookies were inspired by my dad’s upcoming birthday, and his love of all things peanut butter and chocolate. I knew it was the perfect time to bake and photograph these cookies for the site…

Maybe I should have called them Birthday Cookies?

Here’s what you need to know in a nutshell. I use my mom’s base oatmeal cookie recipe and simply add creamy peanut butter and chocolate chunks. Yep, that’s it!


Favorite part? These are the simplest cookie to make. They requiring just one bowl, no chill time, pantry ingredients, and about 30 minutes total. Yes, this means if you got up right now and started baking these cookies, you could finish reading this post with a warm, peanutty, chocolatey oatmeal cookie in hand in about 25 minutes or so.

They’re dangerous, and yet perfect in every way.

The secret to these cookies is to use oil in place of butter. Normally I’m an all butter, all the time, girl. But with this cookie recipe there is no sub in my opinion, oil is what works best.

The second secret is to use a mix of brown sugar and granulated sugar. Now, here’s the deal. I don’t love an overly sweet cookie, so I keep my sugar pretty reduced. That said, if you love a sweet cookie, you might add 1/4 cup additional granulated sugar. But again, I don’t really think it’s needed.

I love using a greater amount of brown sugar because I think it’s flavor is best. But the granulated sugar adds a nice texture and chew that I think serves the cookie well. So use both.

And the third trick? Chocolate chunks. Yes, I know everyone knows about chocolate chunks, but I use a lot. I prefer the dark variety, but milk chocolate is great too. Use what you love.

Oh and then? A nice dusting of flaky sea salt. You don’t have to, but it sure is good…

And with that, I’m going to leave you with the recipe and wish you all a very chill weekend that’s hopefully full of cookies. Ah, the best kind of weekend. See ya Sunday for another round of favorites.

  • 1. Preheat the oven to 350 degrees F. Line a baking sheet with parchment paper. 
    2. In a large mixing bowl, or the bowl of a stand mixer, mix the canola oil, peanut butter, eggs, and vanilla until combined. Add the oatmeal, flour, brown sugar, granulated sugar, baking soda, and salt. Beat until the dough is moist and all the ingredients are combined. The dough will be crumbly. Mix in the chocolate chunks.
    3. Using your hands, clump together about a tablespoon of dough at a time and squeeze into a ball. Place on the prepared baking sheet 2 inches apart and very gently flatten with the palm of your hand just slightly. The dough will be crumbly, this is OK.
    4. Bake for 8 to 10 minutes, or until set and golden. These are crumbly cookies, so let them cool 5 minutes on the pan, then enjoy! 


*As noted in the post, these are crumbly cookies. That is how they are meant to be. The taste and flavor is delicious and we love the texture! Please keep this in mind when making these cookies. If you really can’t get the cookies to hold, add an additional egg to the dough. This will solve the issue.

    Agreed that the cookies were a bit crumbly, but I’m still a fan! Keeping with true HBH style, I added a tablespoon of brown butter and kept the cookies in one minute longer to make sure they set. They’re ideal rainy day with tea cookies!

    These cookies have GREAT flavor! I love using coconut oil in place of butter. I did bake them just a smidge longer and they were great! The leftover “crumbles” will go well in some yogurt 🙂 Great recipe!

  3. Anyone who thought these cookies weren’t good doesn’t know how to bake. Fact is, I don’t know how to bake and I made these and they were amazing! Tasty recipe. Definitely crumbly but in a good way. I used a bit of butter and took out a bit of canola oil. Also added a large spoon of honey.

  4. Yup. Definitely crumbly! I used coconut oil with my recipe and enjoyed the flavours. I did however have to eat the cookie over the sink like a little cookie goblin but that’s okay! Thanks, Tieghan, for the tasty recipe 🙂

    1. Hey Kate,
      Happy Wednesday!! 🌸🌤️ I appreciate you making this recipe and sharing your review, so glad it turned out well for you! xT

  5. The recipe was crumbly I could hardly make a cookie, so I added more coconut oil and managed to make cookies.

    1. Thanks for trying the recipe Marlene and sharing your feedback! Hopefully they came out tasting great! xx

  6. Didn’t like the cookies at all. They tasted like oil to me. Followed recipe to a tea. That was really nasty tasting. I made them for my boyfriend and he agreed they were nasty. I think I should’ve used butter instead of oil

    Love HBH! Everything else has been wonderful. But these cookies not so much. So very dry. Like eating peanut butter sand.
