These Chewy Peanut Butter Oatmeal Cookies Can Be Made With or Without Chocolate Chips!

Oh friends, these Peanut Butter Oatmeal Cookies are going to be a new favorite! I love the combination of oatmeal and peanut butter…and throw in some chocolate chips (optional of course) and you have one of my favorite cookies ever. I would even add in raisins to these too, but I know the raisin police might come at me.

These are actually a pretty filling cookie…the oats, the peanut butter…so good! And I’ve been known to enjoy these for breakfast. I mean, with a cup of coffee or a cup of tea? Seriously good.

Recipe Ingredients:

  • Butter. I use salted butter in this recipe, but you can use unsalted butter if that’s what you prefer.
  • Peanut butter. I recommend using a creamy peanut butter like Jif or Skippy. Using a natural peanut butter in this recipe will result in a more crumbly cookie.
  • Granulated sugar
  • Light brown sugar. You can also use dark brown sugar as well.
  • Eggs. I always use large eggs in my baking recipes. Using extra large eggs will alter the result.
  • Vanilla extract
  • Kosher salt
  • Baking soda
  • All purpose flour
  • Old fashioned oats. These are also know as “rolled oats”. You can use Quick Oats in this recipe if that’s all you have on hand, just reduce the amount of oats by 1/4 cup. Quick oats are simply old fashioned oats cut into pieces for faster cooking!

Optional Add-Ins:

As you can see in the pictures I added in chocolate chips to my cookies. I love the combination of peanut butter and chocolate. BUT these are delicious plain as well! Here are a few more add-in options to get creative:

  • Semi-sweet chocolate chips
  • White chocolate chips
  • Chopped Walnuts
  • Pistachios
  • Chopped candy like peanut butter cups or snickers
  • Dried cherries or dried cranberries

How To Make Peanut Butter Oatmeal Cookies

These are super easy cookies to make and really don’t differ greatly than any other drop cookie recipe. Here are the steps, but make sure to read the full recipe in the recipe card for all the instructions.

  1. Mix the butter and peanut butter together with your mixer until creamy and then mix in both the sugars until light and fluffy!
  2. Next add in the eggs, vanilla, salt, and baking soda and mix until combined making sure to scrape the sides of the bowl to get everything mixed in evenly.
  3. Add in the flour and oats and mix until combined and then stir in the chocolate chips if you’re adding those!
  4. Chill the dough for at least an hour and then bake at 350°F for 12-ish minutes.

Tips For the Best Cookies

  1. This cookie dough needs to chill for at least an hour, but you can chill the dough for up to 3 days before baking. I like to chill oatmeal cookie dough because I feel like it gives the oats a chance to soften a bit. This will ensure your cookies aren’t dry, and will give you a chewy result!
  2. As soon as your cookies come out of the oven you can shape them with your spatula if they are misshapen. DO this immediately because cookies cool quickly! You can also press a few extra chocolate chips on top (if you’re using chocolate chips) to make them look pretty!
  3. These cookies aren’t dry or crumbly at all, BUT if you notice (with this recipe or really most cookie recipes) that your dough is dry or crumbly you can add in 1 tablespoon of milk and mix it up and see if that helps. Add a little more at a time if necessary until you get the texture you want.
  4. Measure your flour by spooning it into the measuring cup instead of scooping. Scooping can lead to packed flour, which will essentially be adding more flour than needed, resulting in a dry or crumbly cookie dough, or leaving your cookie too puffy!

How To Store Homemade Cookies

These cookies are best stored at room temperature in an airtight container. I like to enjoy cookies up to 3 days after they’re baked for best freshness. They will be FINE up to 5 days (some may say longer), but I really don’t like to eat cookies more than a few days old. That’s just me being a cookie snob! BUT I also stand behind 3 days. They just lose a little magic after 3 days.

Can I Freeze the Dough and Bake Later?

Oh yes, absolutely you can freeze this dough. Check out all my tips for Freezing Cookie Dough. The method I outline in that post works perfectly for these cookies.

You can also bake these cookies and freeze them after they’re baked. Just make sure to freeze them in an airtight container. I recommend up to 30 days for best freshness, and then thaw at room temperature.
