These cookies are super soft and packed with oatmeal cookie and peanut butter flavors, which I love. They are so great warm, and they store well, too! If oatmeal cookies and peanut butter cookies had a baby, this would be it!

Such a perfect treat for making cookies with the kids or preparing after-school snacks; these are right up there with my Chocolate Chip Cookies and my Oreo Cookies!

Recipe FAQs

What kind of oatmeal is best for cookies?

In oatmeal cookies, old fashioned oats will give you a chewier texture, and quick oats will result in slightly less chewy cookies, but the flavor is the same. It’s really a personal preference which one you like better for baking, and it also depends on what the recipe calls for. I like quick oats for this recipe, which are the best for the softer texture but still great oatmeal cookie flavor.

Should I use salted or unsalted butter?

The correct answer is to use unsalted butter for baked goods. That way, you can control the amount of salt in the recipe. I like to make my own butter and salt it just how I want. That being said, I love a little extra salt in things, so baking with salted butter is no issue. Use what you like and what you have for this recipe. If you are sensitive to salt, use unsalted! Use salted butter if you like things a little salty (me!).

What peanut butter is best for making peanut oatmeal cookies?

The best peanut butter to use when making these cookies is a
creamy peanut butter like Skippy or Jif. Steer clear of natural
peanut butter for this recipe because it will change the texture of
the cookies. Crunchy peanut butter will also result in a different texture!

Expert Tips

  • Freeze the Dough: To freeze the oatmeal cookie dough, make the dough into balls and then let them freeze for a few hours on the cookie tray (or in a dish so that they aren’t touching much). After the cookie dough balls have frozen through, add them to an air-tight container or a freezer zipper-top baggie. When you are ready to bake the dough, simply preheat the oven, place the frozen cookie dough balls on a cookie sheet, and bake, adding 2-4 minutes to the suggested cook time, as needed. No need to thaw ahead of time.
  • Thick PB: I like to use the thicker peanut butter here that is not the natural kind. If it’s too drippy your cookies will spread when baking
  • Best Oats to Use: I prefer instant or quick-cooking oats for this recipe; they tend to be smaller pieces than old-fashioned oats, and the texture is a little lighter.

Instructions 

  • Preheat the oven to 350 degrees F. and line a baking sheet with parchment paper or a baking mat.
  • In a large bowl (or the bowl of your stand mixer) beat together the butter, peanut butter, granulated sugar, and brown sugar, until the mixture is light and fluffy, about 5 minutes (using a hand mixer if you don’t have a stand mixer is a good option.)
  • Add the two eggs and vanilla and mix to combine.
  • Add the oats, flour, baking soda, baking powder, and salt to the bowl and mix to combine well.
  • Let the mixture rest for 5 minutes and then stir again (this gives the oats time to absorb some of the moisture giving you the nice cookie dough texture).
  • Using a cookie scoop or two spoons, place a large tablespoon of dough on the baking sheet, about 3 inches apart.
  • Bake cookies for 10-12 minutes, until the edges are set and lightly golden brown.
  • Remove from the oven and let cool on the baking sheet for 5 minutes before removing from the sheet and placing on a wire rack to cool.
  • Enjoy right away. Store extras in an air-tight container for up to a week or in the freezer for much longer.

Notes

    • Butter is the best for cookies. It adds great flavor and helps the texture to be nice and crisp
    • For cookies that will be eaten in a day or two, store soft cookies in a container with a tight-fitting cover. 
    • Both granulated and brown sugars are great and add color and flavor to the finished cookies
    • The key to keeping cookies fresh and soft is to seal them in an airtight container, like a resealable freezer bag. And here’s a nifty little trick: add a piece of bread to the bag.

    A really good cookie! Made with gf flour (Domata is my fav) and Quaker gf instant oats. Batter will be glue like since it’s gf but don’t worry! I didn’t flatten the first set (on the upper left) but I did on the rest with a spoon after someone mentioned it. I cooked to 12 minutes for all and was perfect! I even added chocolate chips and holy cow it’s really, REALLY GOOD! Crunchy on the outside and soft and chewy on the inside. Amazing!!
