Peanut Butter Oatmeal Cookies

These peanut butter oatmeal cookies are soft and chewy and soooooo DELICIOUS! They have the perfect amount of creamy peanut butter flavor. And adding rolled oats makes them a (slightly) healthier cookie option.

This recipe is super simple to make – in less than half an hour, you’ll have homemade oatmeal peanut butter cookies that are SO GOOD. I like these even better than regular peanut butter cookies!

I love peanut butter cookies. And I love oatmeal cookies. And I’ll admit, I’ve never tried to combine the two recipes before, but WOW – these cookies turned out so well! I couldn’t stop eating them. The oatmeal gives them a slightly more wholesome flavor than plain peanut butter cookies. I’m a huge fan of soft cookies and these were a big hit!

I used my trusty old hand mixer to make these cookies. So trusty, in fact, that I covered a good portion of the mixer in masking tape at Christmas last month because the rubber was starting to come off. If you’ll notice in the photos, I conveniently left out the ones showing the mixer. LOL

This recipe makes about two dozen cookies (I made exactly 25 cookies to be precise), and they disappeared in a day. My kids ate at least 2 each when they got home from school. And I ate 2 when I made them, 2 after dinner, 2 after breakfast the next day, 2 after lunch, and again 2 after dinner… I will definitely be making them again!

This peanut butter oatmeal cookie recipe is so good! It’s pretty much a basic cookie recipe, except we’re replacing half the flour with oats.

I’ll give you some tips down below for the best type of oats to use.

Peanut Butter Oatmeal Cookies - Ingredients

Doesn’t the dough look delicious!? The photo below is after I stirred in the oatmeal. It was surprisingly light and fluffy!

Peanut Butter Oatmeal Cookies - Mixing the dough

Form the peanut butter oatmeal cookie dough into balls. The balls should be about 1.5 inches wide. Place them about 2 inches apart on a parchment lined baking sheet.

The dough spreads out quite a bit when you bake them, so there’s no need to flatten the balls. In fact, since they start in a ball shape, they middles end up being super soft and moist. SO GOOD.

When I pulled them out of the oven they were still really puffed up. But don’t let it fool you – the cookies below are DONE!

About 15 minutes after they come out of the oven they flatten out. And those mouth watering cracks form in the top of the cookies.

The more “blonde” your cookies look in the oven, the softer they’ll be. And the more “golden” the cookies look, the harder/crunchier they’ll be.

The cookies have the traditional cracks that peanut butter cookies have. But if you look at the texture, they also have the bumpy texture of oatmeal cookies. A seriously amazing combination!

Fair warning, they’re super addictive!

What Kind of Oatmeal is Best for Healthy Peanut Butter Oatmeal Cookies?

Technically you can use any type of oatmeal for these cookies – quick cooking oats, old fashioned oats, rolled oats, etc.

We used rolled oats in the cookies you see in the photos. To make a softer texture, we poured half the rolled oats into a mini food processor and pulsed them until they were a little more finely ground. This is totally optional! But I find it helps give the cookies a smoother, less grainy texture.

If you don’t have a food processor you can use two different types of oats. Use half large flake oats (such as old fashioned oats) and half quick cooking oats for a soft and delicious cookie texture.

Tips for Making Peanut Butter Oatmeal Cookies

  • Bake the cookies on a parchment lined baking sheet.
  • Allow the cookies to set for at least 10-15 minutes before trying to move them off the pan.
  • Use creamy peanut butter, rather than natural peanut butter. We cut down the sugar in this recipe to account for the extra sugar in the peanut butter.
  • To keep the dough from sticking to your hands when you’re rolling the balls of dough, keep a bowl of water close by and dampen your hands slightly between each ball.
  • Use light brown sugar instead of dark brown sugar. (Dark brown sugar has more molasses and therefore has a stronger flavour).
  • If you decide to add chocolate chips, choose milk chocolate chips instead of regular semi-sweet chocolate chips. Milk chocolate tastes better with peanut butter.
