If you’re a peanut butter fiend, these Peanut Butter Oatmeal Cookies are for you! They’re soft and chewy and 100% peanut butter lover approved!


I love trying to figure out how to turn recipes that would normally be considered “junk” food into nutritious snacks that you aren’t afraid to give your kids. I’m not big on totally depriving kids of junk food (I feel like that only leads to a slew of other problems in the long run), but if I can come up with a version of a cookie that doesn’t include all of the unnecessary fillers found in store bought brands, I’m making it homemade for my kids.


These Peanut Butter Oatmeal Cookies will have your family’s eyes popping wide open when they see them coming out of the oven. These cookies have a healthy carbohydrate from the oatmeal and a protein punch from the peanut butter — great for kids who have been active running around all day. All they’re going to care about though is that they are delicious!


I made a batch of these for an after-school snack and everyone went wild. My kids have always been obsessed with peanut butter so these were a natural fit.

I love these cookies too because they’re super simple to whip up when we want something special for a snack or after dinner treat. And the ingredients are pretty much always in our pantry and refrigerator which makes it even easier! They’ve become one of our go-to’s lately and I’m not complaining.

  1. Just made these with wheat bran and whole wheat flour instead of oats and flour. Turned out crumbly but so soft and yummy! Thanks

  2. First off, let me start by saying that I adore weelicious and most of the recipes on here. But unfortunately I didn’t have much luck with these cookies. I baked them three different times underbaking them a little more each time, and every time they came out just to dry. They are also a little bland for my taste (and my 3yo’s) and believe it or not my husband was surprised that there was peanut butter in them. I think the poster who suggested using less flower might be onto something. I also used honey and maybe the agave would give a sweeter flavor. Oh well, I’ll still keep trying weelicious recipes! And I really appreciate the attempts to make our favorite sweet treats healthier too!

  3. […] and I (and Rufert) are all set to make Weelicious’s Peanut Butter Oatmeal Cookies for Santa on Christmas Eve. Following Catherine’s advice to keep kids involved in cooking, […]

  4. Hi, if I want to make these dairy free and sub coconut oil for butter, how much would I use? Thanks!

  5. I love this website. I have made a ton of recipes from this site. However, this one was a big flop! I followed the recipe exactly and the cookies turned out very dry and crumbled in our hands. The flavor was a bit bland as well.
