Who here loves to enjoy a nice, warm peanut butter cookie every once in a while?? We do!! They are usually chewy, tasty, and the perfect combo of sweet and salty.

We took our best Oatmeal Cookie recipe and our softest Peanut Butter Cookie recipe and combined them to create delicious peanut butter oatmeal cookies! They were a match made in heaven.

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 – some added chewiness, making them quite irresistible.

We have to say, they are probably our FAVORITE peanut butter cookies!

Why we think you’ll love it:

  • Extra chewiness. The addition of oats gives texture and makes these extra delicious!
  • The best of both worlds. You still get that sweet and salty peanut butter flavor that we all know and love with the texture of an oatmeal cookie!
  • No chill time required. These cookies are quick and easy cookies. You’ll be dipping your first batch in milk in under 20 minutes!

How to Make Peanut Butter Oatmeal Cookies

  1. PREP. Preheat oven to 350°F.
  2. BATTER. Use a stand mixer with the paddle attachment (or an electric mixer and a large bowl). Cream butter, brown sugar, granulated sugar, and creamy peanut butter until smooth. Add eggs, one at a time, and beat until well blended. Add vanilla.
    • In a separate bowl, combine the flour, baking soda, and salt. Stir into the creamed mixture. 
    • Mix in quick oats until just combined, scoop with a cookie scoop, use a fork to press a crisscross pattern on the top of each cookie (so they bake more evenly), and place onto a cookie sheet. 
  3. BAKE. Bake for 12-14 minutes. Pull the cookies out of the oven just as the edges are browning. Leave them on the baking sheet for a few minutes to allow them to finish baking and begin to cool before transferring them to a wire rack to finish cooling off. ENJOY!

    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.

    1. Kristyn Merkley says:

      Oops, sorry! I will fix that. Yes, add it after the eggs. Thanks for letting me know!

  2. Natalie says:

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

    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!

    Whe do you add vanilla? And cookon greased or ungreased pan?

    1. Kristyn Merkley says:

      Sorry, you can add it with the eggs 🙂 I like to bake my cookies on parchment paper, but sometimes, I will very lightly spray.

  8. Donna G says:

    I don’t have a cookie scoop. So would I use a teaspOon or tablespoon in leu of one? ThaNks!

    1. Kristyn Merkley says:

      I would just use a tablespoon. It really depends on how big or small you’d like them 🙂

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

  10. Linda says:

    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. Kristyn Merkley says:

      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!

  11. Shannon - Sweets & Treats says:

    These look delish! I’ve never thought to put oatmeal with peanut butter!

    1. Kristyn Merkley says:

      Thank you! I hadn’t either, but wish I would have sooner!

    2. Nancy says:

      what kind of oats do you use rolled or quick?

      1. Kristyn Merkley says:

        I usually use quick oats 🙂
