Summary
- Full of flavor: Intense peanut butter flavor, highlighted by vanilla, a touch of salt, and a hint of caramel from the brown sugar, plus hearty oats. It’s a winning cookie combination!
- Perfect cookie texture: Slightly crispy edges give way to soft-and-chewy, melt-in-your-mouth cookie centers.
- Wholesome peanut butter and oats: These homemade PB oatmeal cookies have protein from the peanut butter plus insoluble fiber from thick rolled oats, creating a cookie that’s not only a sweet treat, but provides some filling nutrients too.
- Easy and fast to make: The cookie dough mixes up quickly and easily in your stand mixer! Plus, no chilling time is needed.
Ingredients to Make Peanut Butter Oatmeal Cookies
- Butter: I suggest unsalted butter so that you can better control the salt content in your cookies.
- Light brown sugar: The higher moisture content in brown sugar helps give cookies a chewy texture.
- Sugar: Cane sugar or granulated sugar will work.
- Creamy peanut butter: Creamy, natural peanut butter without added sugar or oils is best in these cookies.
- Vanilla extract: Adds a note of sweet flavor that’s perfect in cookies.
- All purpose flour: I suggest all-purpose flour for best results. For an even heartier cookie, you can replace half of the all-purpose flour with whole wheat, but the cookies will be a bit more dense.
- Baking powder: This leavener helps the cookies puff a bit and spread just enough.
- Salt: Highlights the peanut butter flavor and offsets the sweetness of the sugars.
- Old-fashioned oats: Use rolled/old-fashioned oats for the best results. Quick-cooking oats are cut smaller and won’t give you the hearty oat texture that thicker old-fashioned oats will.
Popular Substitutions & Additions
- Swap creamy for crunchy. I love creamy peanut butter in these cookies, but crunchy peanut butter is a swap you can make for a bit more crunchy texture.
- Add chocolate chips: Add a cup of dark or semisweet chocolate chips for a chocolatey touch that pairs well with the oatmeal and peanut butter.
- Warm with spices: A half teaspoon of ground cinnamon and/or a pinch of nutmeg adds a cozy note to your peanut butter oatmeal cookies.
- Make them dairy-free: Swap the butter for vegan butter or coconut oil for a dairy-free version of these cookies.
How to Make Peanut Butter Oatmeal Cookies
These homemade PB oatmeal cookies are so easy to make! Just mix up the dough in your stand mixer, then scoop onto a cookie sheet and bake. Allow to cool and enjoy!
Make the Cookie Dough
- Place softened butter and sugars in the bowl of a stand mixer and cream together until light and fluffy.
- Add the peanut butter and combine well.
- Add the egg and vanilla and mix until incorporated.
- In a separate bowl, whisk together the flour, baking soda, and salt. Add to the wet ingredients and mix just until combined.
- Add the oats to the dough.
- Mix together just until incorporated.
Bake the Cookies
- Use a cookie scoop to scoop rounded balls of dough onto a parchment-lined baking sheet. Lightly flatten the top of each cookie with your fingers.
- Bake until the edges are set and lightly golden.
Tips for Making the Best Oatmeal Cookies with Peanut Butter
- Don’t overbake: Bake cookies just until the edges are lightly golden and the middles are set. They’ll finish cooking once they’re out of the oven, and once cooled, they will have the perfect texture.
- Use room-temperature ingredients: It’s important that your butter is at room temperature so that it will combine easily with the sugars. For best results, also make sure your egg is at room temperature so that it doesn’t cause the butter to solidify when it’s mixed in.
- Mix just until incorporated: When you add your dry ingredients to the wet, mix only until the ingredients are incorporated. If you overmix, you risk developing the gluten in the flour, which can result in a dense, tough cookie.
- Use a cookie scoop for uniform, round cookies: Scoop and place your cookie dough with a cookie scoop for perfectly round, equally sized cookies.
How to Store Peanut Butter Oatmeal Cookies
After your peanut butter oatmeal cookies have cooled completely, transfer them to an airtight container, separating layers with parchment paper to prevent them sticking to one another. Store them at room temperature for up to one week.
How Long Will Peanut Butter Oatmeal Cookies Last in the Fridge?
I don’t recommend storing peanut butter oatmeal cookies in the refrigerator because they will dry out. However, if you want them to last longer than a week and don’t want to freeze them, it’s an option; they will last about two weeks in the refrigerator.
Can I Freeze PB Oatmeal Cookies?
Yes! You can freeze the baked cookies for snacking directly out of the freezer. Just place them in an airtight container or freezer bag and place in the freezer. They will last for up to 3 months.
You can also freeze balls of cookie dough for fresh-out-of-the oven cookies whenever you like, you can freeze the dough balls. Scoop prepared dough onto your baking sheet, then freeze for a few hours. Transfer the frozen cookie dough balls to a freezer bag and store in the freezer. When the urge for cookies strikes, place frozen cookie dough on a baking sheet and bake! You may want to add a few extra minutes cooking time because you started with frozen cookie dough.

I just made this cookies and they are so delicious my kids loved them 😋
Yay! Thanks for sharing.
This recipe is so delish! Added mini chocolate chips. They were devoured. Thanks for sharing!
So happy you loved them!
Possible to switch the peanut butter for almond butter?
Hi there! I have not tried that yet myself, but I think it would turn out well!
Quick, easy and delicious! I love the pb & oats combo. These would be great with vanilla ice cream!
Yum, love that idea!
My family didn’t care for these at all. I made as directed and they were dry and bland. The idea of combining peanut butter with oatmeal intrigued me, but not with this recipe.
So sorry to hear these did not come out as expected. Is there any chance they might be slightly overbaked? I like to check them at the earliest possible cooking time, and when the edges are just turning golden, and the middles are set, they’re ready to come out of the oven.
I loved these cookies. They whipped up quickly. Great flavor and consistency.
Thanks so much!
These were so good and simple with ingredients I already had on hand. Next time might add some chocolate chips. Thanks for another great recipe!
Sounds like a great plan!
Would it change the dynamics of cookie if the pb was crunchy
I love creamy peanut butter in these cookies, but crunchy peanut butter is a swap you can make for a bit more crunchy texture.
