Peanut Butter Oatmeal Cookies

Two of everyone’s favorite cookies in one – these Peanut Butter Oatmeal cookies are soft, chewy and so delicious! They take regular PB cookies to a whole new level.

We took our best oatmeal cookie recipe, and our softest peanut butter cookie recipe and put them together to create a delicious new cookie recipe! A match made in heaven!

A perfect combo

Who here loves to enjoy a nice, warm Peanut Butter cookie every once in awhile?? I do!! Although they haven’t always been my favorite, I do enjoy PB cookies. They are usually chewy, tasty and the perfect combo of sweet and salty.

We recently saw a recipe for Peanut Butter Oatmeal cookies and knew we HAD to try them. I mean, we are mildly obsessed with our Coconut Oatmeal Cookies and knew that oats would be an amazing addition to these cookies. Boy, am I glad we tried them because I think I can officially say they’re my favorite peanut butter cookies!!

Oatmeal cookies have always been a hit in our house, but combining two of our favorite cookies into one made for an even better recipe. OATS were definitely perfect for this cookie recipe making them soft, delicious and quite irresistible.

How to make Peanut Butter Oatmeal Cookies:

We love that these cookies are simple and delicious. As I mentioned above, the dough is so good and addicting, so don’t say we didn’t warn you.

To make these cookies it takes just a few simple steps. They’re so simple even the kids can help out. Here is what you gotta do…

WET INGREDIENTS. In kitchen-aid (or large bowl) cream together butter, sugars and peanut butter until smooth. Add eggs one at a time and beat until well blended.

DRY INGREDIENTS. In a separate bowl, combine the flour, baking soda, and salt. Stir into the creamed mixture. Mix in oats until just combined.

SCOOP & BAKE. Scoop with cookie scoop onto cookie sheet. If you want criss cross patterns on your cookies (typical of a peanut butter cookie), lightly press a fork on top of the dough to make criss cross imprints. Bake at 350°F for 12-15 minutes.

Recipe Tips 

  • Stay away from natural peanut butter. Use Skippy, JIF, generic store brand or something similar.
  • To add texture, use crunchy peanut butter
  • To change up the taste, try adding chocolate chips or a ½ tsp of cinnamon.
  • Chill the dough before scooping it. This will help make a nicely baked outside and a soft chewy inside.

How to store/Freeze

Baked Cookies: Keep baked cookies in an airtight container on the counter for about 4 days. To keep the cookies even fresher, place a slice of bread in the container as well. To freeze them, allow cookies to completely cool. Place in a freezer safe container separating layers with parchment paper. Freeze for up to 3 months.

Dough: You can store cookie dough in the fridge. Cover the bowl with plastic wrap and store for 1-2 days before baking. 

To keep the dough even longer, flash freeze it by scooping dough balls onto a baking sheet. Freeze for about 2 hours. Transfer dough balls to a freezer safe container, label and freeze for up to 3 months. When baking, place the desired amount of cookies on a sheet, let thaw for about 30 minutes and bake according to recipe directions.

We sure do love making cookies! It’s something the kids can easily help with and we are so glad we have another go-to cookie recipe to add to our ever-growing list.

Even though you may not regularly add oats to your PB cookies, I want you try it out. I think you’ll enjoy way more than you think. 😉

  1. Picture looks like the cookies have fork impressions – how thick was the pressed dough (approximately)? These look yummy – can’t wait to try! Thanks <3

    1. They are in balls on the cookie sheet. I just lightly pressed with a fork to get the impressions, but I didn’t press them flat. They are super yummy!

    I never thought to add peanut butter to what is already a delicious cookie, but oh, adds so much more! My husband loved them!! they were soft & crispy at the same time.

    I can’t say that I have ever made Peanut Butter Oatmeal Cookies. Now that I have, I am never going back to the traditional Peanut Butter Cookies. The texture and flavor is SO MUCH BETTER!

    Adding the oatmeal in these cookies is a delicious idea! Two of our favorites! I might have to add some chocolate chips, too!

    Great recipe I am making them right now. You failed to mention the vanilla in the steps. I assume it goes in the creamed portion before the dry ingredients are added.
