These PB&J Bars are a take on the classic sandwich we all know and love. Made with protein-packed peanut powder, oat flour, organic jam and coconut oil, you can feel good about enjoying these bars whenever you please.
I’ve made plenty of crumble bars before (like these amazing healthy blueberry crumble bars), but for some reason I never thought to make PB&J Bars — until now.
I honestly find this hard to believe because we’re huge PB&J fans over here at EBF. I ate a PB&J sandwich almost every single day for lunch throughout elementary, middle and high school. Isaac’s childhood was similar and to this day he still makes peanut butter and jelly sandwiches for lunch or a snack. You know, just your causal sandwich snack.
Because of this, I’ve come up with so many PB&J inspired recipes including a PB&J Smoothie (this baby is SO good), PB&J Trail Mix (such a fun combo if you can find the peanut butter chips), PB&J Overnight Oats (perfect high-protein breakfast) and PB&J Protein Bites.
And today I’m adding these PB&J Bars to the list. They’re like a standard crumb bar only made healthier with good-for-you ingredients. I think they’d make an awesome lunch box addition, but only if your kiddo goes to a school where peanuts are still allowed. (Do peanut-friendly schools even exist anymore? Clearly, I’m not a mama so I’m out of the loop.) If peanuts aren’t an option at school, just pack one in your own lunch box and save a few for the kids to enjoy as an after-school snack.
I’m sure most of you reading realized this already, but I just want to point out that these aren’t just for kids. Truth be told they’ve only be taste-tested by adults but everyone LOVED them so I’m sure kids will like them too.
What I love about them is that they’re incredibly easy to whip up. We’re talking one bowl, 8 ingredients and only about 15 minutes of hands-on prep time.
I found everything I needed for this recipe at my local Kroger and all the items (besides the baking soda) are from their Simple Truth line, which features natural and organic products. All of the Simple Truth items are free from 101 different artificial preservatives and ingredients including things like high-fructose corn syrup, hydrogenated fats & oils, sucralose, aspartame and parabens.
For the peanut butter flavor, I used the Simple Truth protein-packed peanut power. If you’re unfamiliar, peanut powder (or peanut flour) is made from crushed, defatted peanuts so it has a ton of peanut flavor and protein, but it’s lower in fat and calories. It’s been popular among health food enthusiasts (i.e. people like me) for a few years now. You can use it as a peanut butter substitute, just by adding liquid to the powder, but I primarily use it as to give a peanut butter flavor (and protein boost) to things like smoothies, sauces, overnight oats and pancakes. (Check out my peanut flour protein pancakes here.)
Peanut powder also works for baking and these PB&J bars are a great example. They have a ton of peanut butter flavor, just from the peanut powder! And 9 grams of protein per square.
Of course, for the photos I added a little drizzle of actual peanut butter, but that’s totally optional. 🙂

PB&J Bars
Ingredients
- 1 1/2 cups oat flour
- 1 cup Simple Truth Peanut Powder
- 1/2 cup coconut sugar
- 1/2 cup melted coconut oil
- 1 egg, whisked
- 1/2 teaspoon vanilla
- 1/2 teaspoon baking soda
- 1/4 teaspoon sea salt
- 3/4 cup organic strawberry jam, store-bought or homemade*
Instructions
- Preheat oven to 350° F. Line a square baking dish (8×8 or 9×9 will work) with parchment paper or spray with a little coconut oil non-stick spray.
- Mix oat flour and peanut flour in a large mixing bowl. Add coconut sugar, coconut oil, whisked egg, vanilla, baking soda and salt. Mix well.
- Measure out 1/2 cup of the dough and set aside. Press the rest of the dough evenly into the baking dish using your hands.
- Add strawberry jam on top and spread evenly to cover the dough.
- Crumble remaining dough over the strawberry jam layer and press everything down lightly.
- Bake for 35-40 minutes until the bars a golden brown. Remove from oven and allow bars to cool in the baking dish before slicing and removing.

Hi! Just wanted to pop by and say I think perhaps the ingredients list should be updated to say “1/2 cup melted coconut oil” instead of “1/2 cup coconut oil, melted.” If you measure half of a cup of coconut oil in its solid state and then melt it, as the instructions indicate with the placement of that comma, it will only equal about a 1/4 cup. That may be why some folks found this to be extremely crumbly–myself included! 🙂
Hi there! Thank you for the note. I will be sure to update this so it isn’t confusing for people. 🙂
Can i bake it using Airfryer instead of an oven?
I can’t stop eating these! They bring out everything great about peanut butter and jelly sandwiches, while being an excellent, bite-sized snack. I might go down on the sugar because the jam is already sweet, but this is just preference. I loved the idea of using peanut powder as a sort of flour.
Woo!! So pumped you’re enjoying these pb&j bars, Madeline! Thanks so much for trying them out and coming back to leave a review. It means so much to me!
this recipe looks delicious, but was wondering if there was a substitute for coconut oil…would canola or avocado oil work as well?.thanks!
I think that would work just fine, Paula! Let me know if you try these bars and what you think 🙂
These look delish, but I am not a fan of coconut oil..what could I use as a substitute?..thanks!
These look and sound amazing! i’m on a total PB&J kick right now. I was wondering if you could possibly replace the egg with something else? Is it just acting as a binder in this recipe? Maybe a flax or chia egg? Applesauce? Mashed banana?
You could totally try it with a flax or chia egg! I haven’t tested it, but I bet it would work just fine. Let me know if you try it and how the bars turn out. 🙂
Like your recipes, they look good. I will try to make some. Do you have keto friendly ones?
Hey Christine, I don’t follow a keto diet, but many of my recipes can be made to fit a keto lifestyle if they aren’t already. 🙂
