I've been trying to perfect a peanut butter version of my baked Oats & Honey Granola Bars for awhile now, and along those lines, I was tinkering with the recipe several weeks back. While my resulting concoction didn't exactly turn out like the crunchy granola bars I envisioned, it did end up resembling soft-baked oatmeal bars. So I suppose in this case, a kitchen fail of one sort turned into a kitchen triumph of another...Peanut Butter Oatmeal Bars!

I've made this recipe a couple of times since and my family really enjoys it. I love that it's a ready-made breakfast, because during the summer at Casa de Five Heart Home, three young individuals eagerly wake up at the crack of dawn. And you see, this foils Mama's plan of indulging in the luxury of "sleeping in" (until a whopping 7 a.m.) so long as school is out.

So when the toddler pries open my eyelid at 6:30 a.m. with a "Mama, I hungry," I can simply whisper, "Okay, baby...go ask your brother to get you a peanut butter bar." And when she scampers off, it's at least five full minutes before she pries open my eyelid again.

"Mama. He got me a pee-buh bah."

Glad to hear it, sweetie. Now why don't you go ask him to pour you some milk, thereby allotting me five more precious minutes...?

In all seriousness, though, these Peanut Butter Oatmeal Bars are the definition of honey-sweet, soft-baked yumminess. They're great for breakfast, at home or on-the-go, and they're a perfectly portable snack. They're also somewhere in between the Chewy No-Bake Granola Bars and the crunchy baked granola bars that I typically make, so it's always fun to change things up.

Ingredients

The ingredients for these Peanut Butter Oatmeal Bars are simple, straightforward, and wholesome!

  • Old-fashioned rolled oats. I prefer making this recipe with rolled oats for their chewier texture. However, if you only have quick oats on hand, they should work fine...you just may want to use slightly less since they're packed more densely.
  • Whole wheat pastry flour. I love whole wheat pastry flour because it's 100% whole wheat but with a lighter taste and texture (more akin to that of all-purpose flour) than regular whole wheat flour. If you wish to make these gluten-free, you may use oat flour instead. (You can find instructions for how to make oat flour under Tips & Tricks below or in the Notes section at the bottom of the recipe card.)
  • Brown sugar. Just a smidge! Feel free to use light or dark.
  • Cinnamon. Tweak the amount to your liking.
  • Salt.
  • Coconut oil. Make sure it's melted and cooled. Alternatively, if you wish, you may use any other neutral-flavored oil or even melted butter.
  • Honey. Maple syrup may be substituted.
  • Egg.
  • Pure vanilla extract.
  • Peanut butter. Any type of peanut butter should work. I prefer using a natural peanut butter, and I've made this recipe with both crunchy and creamy. You may also choose to use another type of nut (or non-nut) butter if you like, such as almond butter or sunflower seed butter.
  • Chopped peanuts. These are optional -- but recommended -- for sprinkling over the top of the bars before baking.

How to Make Them

This recipe is so simple that my biggest boy can practically whip it up by himself.

  1. Whisk together the dry ingredients.
  2. Stir in the wet ingredients.
  3. Add the peanut butter and mix until well combined.
  4. Scrape the batter into a pan and sprinkle with chopped peanuts.
  5. Bake until just golden brown.
  6. Cool, slice, and enjoy!

See? Easy-peasy!

I hope you get to try these Peanut Butter Oatmeal Bars soon, because I think you'll enjoy them.

And if you're lucky, they may even buy you an extra five minutes of sleep.

Now that's what I call magic. 😉

Tips, Tricks, & Equipment

  • To make oat flour, use a blender or mini food processor to grind 1 ¾ cups oats into a fine powder. Measure out 1 ¼ cups of oat flour for the recipe after grinding. If you have leftover oat flour after measuring, you can always save it for a Blueberry Muffin Healthy Oat Smoothie. 🙂
  • If desired, you may reduce the brown sugar.
  • To save a dirty dish, I melt the coconut oil in a measuring cup in the microwave and then measure the honey and vanilla on top. The coconut oil helps the honey slide out of the measuring cup.

  1. Great,great recipe made them and shared them at work got many compliments, I was wondering if I could use almond butter and almond flour

    1. Hi, RoseMarie! Almond butter would work as a straight substitute for the peanut butter in this recipe, but almond flour has different properties than wheat flour and would probably require the recipe to be modified.

  2. I really like the flavor of these bars and have made them twice. I am trying to figure out how to make them so they don't crumble so badly, they cut into bars OK but tend to break or crumble very easily. Any thoughts on how to make them a little more moist and more pliable without crumbling so bad? Great flavor.

    1. Hi Molly! I haven't tried substituting, but I bet quick-cooking oats would work just fine in this recipe. The bars will probably turn out softer using quick oats (as opposed to chewier using old-fashioned rolled oats), but they should still be tasty. Enjoy! 🙂

      1. 4 stars
        These bars are so yummy! Hard to put down for sure, they were a big hit! I did use brown sugar sweetened with stevia and all natural sugar free peanut butter. They were great! Thanks for the recipe.

    1. Hi there! I apologize for the delayed reply...I've been out of the country. I've only made these with coconut oil, but you could try making them with melted butter or a mild oil like canola or safflower (though, again, I haven't tried those substitutes). Hope they turn out well if you make them! 🙂

  3. These look so delicious! We can't have them because my daughter is allergic to oats, but if there is ever a day she isn't home, I'm gonna make these!

    1. Hmmm, Joanna...I wish I could think of a substitute for the oats so that your daughter could enjoy these, too! Is there another grain that you've had success swapping out in recipes for her?

  4. As soon as I laid eyes on these, I knew I HAD to make them that afternoon. They were easy to make and a yummy blend of flavors. My husband grabbed the ones that were left to take to work and share with his friends there. I guess I didn't really need to eat the rest all by myself anyway. Thanks for another great recipe!

    1. Ha, Carolyn...glad these were a hit! And so kind of John to share with his co-workers, although I guess that means you just have to make another batch for the home front. 😉 Hope you're having a great week and staying cool!

    1. Thanks, Eric! I appreciate you stopping by and hope you enjoy these if you have a chance to try them! 🙂
