These Oatmeal Peanut Butter Cookie Bars are about to change your life. They’re gooey on the inside, made with wholesome ingredients, and kid-friendly! This oatmeal cookie bars recipe uses all-natural sugar (hey, maple syrup!), white whole wheat flour, rolled oats, and all-natural peanut butter to keep these peanut butter oatmeal bars healthy and better-for-you! It’s Friday and you deserve a COOKIE BAR. But, these aren’t you average peanut butter cookie bars… They’re Peanut Butter Oatmeal Bars. You guys died over this sneak peek on Instagram stories, so we rejiggered our content calendar to get these up ASAP. We also made them two more times to make sure they’re perfect…and, well, they are! These peanut butter oatmeal bars are a spin-off of our Grain-Free Chocolate Chip Cookie Bars, but we added in some rolled oats and white whole wheat flour for more of a traditional cookie bar texture. This recipe is gooey, satisfying, and just the best. They’re not too sweet and you don’t have to worry about refined sugars because these peanut butter cookie bars are made with maple syrup and you can use vegan chocolate chips to keep things 100% dairy free.

Peanut Butter Cookie Bar Swaps
- White whole wheat flour –> I recommend swapping with either all-purpose, whole wheat flour, or a gluten-free flour blend. Swap recommendation is 1:1. Note: Do not swap 1:1 for a nut-based flour such as almond flour, coconut flour, etc.
- Peanut butter –> Good news! Any kind of nut butter works for this recipe! My favorite other than peanut butter is cashew butter! Swap recommendation is 1:1.
- Maple syrup –> If you’re hoping to swap the maple syrup for another kind of sugar, make sure you use a liquid sweetener such as honey or agave. Swap recommendation is 1:1.
Storage
Store these delicious peanut butter oatmeal bars in an airtight container in the refrigerator for up to 5 days. Freezer instructions: to freeze, place cooled bars on a cookie sheet. Then, freeze for 1 hour. Transfer bars from cookie sheet to a freezer-safe gallon-size bag. Remove as much air as possible and freeze for up to 3 months.More Healthy Dessert Recipes

Could almond flour be subbed?
These are AMAZING- so easy & delicious. I used chunky peanut butter (because why not) and big chocolate chips and they turned out perfect!
YUM YUM YUM! Not gonna lie, if I made these bars, I wouldn’t share them with ANYBODY! LOL! But anyways, I would love to make this recipe but I need to substitute the eggs and the honey. Have you had success with flax eggs and maple syrup?
Hello! These look amaaaaaaaaazing but I was wondering if youโd have any suggestions for making it lower fat (replacing some of the pb with something else?)
HI Yive
I’m not Lee…but trust me, I made these of the weekend (they are AMAZING !) and you want to make them with the real deal PB as suggested.
To help with intake control….I wrap the bars individually in plastic wrap, put them in a freezer safe bag and freeze those guys. When you’re ready for one, leave out on the counter for about 30 minutes.
Hope this helps !
These are wonderful!
Are these best to store in an airtight container in the fridge or on the counter?
Thanks

How do I make them into 9 servings from an 8×8 pan? Maybe I’m just tired but I can’t wrap my head around it.
You just cut 3 rows by 3 rows! To get 9 bars ๐
3 rows by 3 rows = 9 pieces
Well clearly I’m the one who can’t do the math ๐
What can I use instead of maple syrup
You can sub honey!
You NEED to try Teddie Peanut Butter. Iโm obsessed. Nothing but peanuts, salt, and unicorns in there. I order 3 jars at a time on Amazon!!!
I haven’t had Teddie Butter in forever!
Can you use All-purpose flour instead? Thank you
Yes, you can!
YUM!!!!!! I already know Iโd be obsessed with these bars. You should try Crazy Richardโs PB too if you havenโt! Another good one!
YES I DO. I’ve heard great things!
