What are your favorite snacks to bring with you on-the-go? Erik and I love walking all over the place, so we’re always searching/looking for ways to make healthy vegan treats that stay yummy without a fridge and are super portable.
I mean… unless you’ve got a teeny-tiny, like nearly microscopic mini-fridge/purse you can recommend? 😉 J/K!
I’ve noticed over many, many meal preps/snack preps for our excursions that no bake snacks truly fit the bill. They’re so easy to make, easy to customize with gluten free ingredients, and are seriously yummy.

Healthy Peanut Butter Oat Bars with just 4 Ingredients!
Peanut Butter
I love using unsalted, natural creamy peanut butter to make these healthy peanut butter oat bars! Since I make many of these recipes with my mom in mind, I’m vigilant to leave out any unnecessary sources of sodium, like salted peanut butter. You can try that if you like, just keep in mind that it’ll affect the flavor of these gluten free peanut butter oat bars. It’s the same PB that I use in my 3 Ingredient Keto Chocolate Peanut Butter Fat Bombs.
Gluten Free Oats
Make sure to use gluten free rolled oats aka old-fashioned oats to make these vegan peanut butter oatmeal bars. Quick oats, or 1-minute oats are much thinner and will yield a different result. For more tasty PB oatmeal recipe try my Healthy Peanut Butter Overnight Oats Recipe (Vegan, Gluten Free) and my 3 Ingredient No Bake Peanut Butter Oatmeal Cookie Cups.
Pure Maple Syrup
Pure maple syrup is one of my favorite ingredients to use in vegan gluten free baking. The flavor & sweetness of maple syrup is incredible! Plus, it makes these healthy peanut butter oat bars refined sugar-free (just make sure to use a vegan chocolate that’s refined sugar-free).
Vegan Chocolate Chips
There are a variety of dairy-free/vegan chocolate chips available. These vegan chocolate chips are allergy-friendly and melt very smoothly. Here’s another popular brand of allergy-friendly vegan chocolate chips. You might also try chopping up this paleo chocolate bar to ensure that these healthy peanut butter oat bars are not only gluten-free & healthy, but also refined sugar-free.
Can I Freeze these Vegan Peanut Butter Oatmeal Bars?
Yes! I actually have a batch of these vegan peanut butter oatmeal bars in my freezer as we speak. To Freeze: after chilling and slicing, carefully place chocolate peanut butter oat bars in a freezer-friendly container or bag. Freeze oat bars for up to 2 months. Remember to thaw the oatmeal bars before enjoying!

I made these last night when a craving for something chocolaty hit. They were AWESOME! So simple and so delicious. I’ll definitely be making these again. These would be great to bring to share at work or any other gathering. If I made them to bring somewhere, I’d double the amount of the oats portion (per 8×8 dish) and make a little more of the chocolate part too since mine came out looking short/flat in comparison to the beautiful ones in your pictures. Thanks so much for this recipe!
I’m so glad that you enjoyed the bars Siara! And I am sure yours came out absolutely gorgeous!
My husband is allergic to peanuts. Would sunflower butter work in this recipe? Would I need to make any changes to the measurements of the other ingredients? Thank you!
Hi Vanessa, feel free to use sunflower butter in place of the peanut butter, 1:1. You can use the same amount. 🙂 Hope you enjoy!
Great recipe! I found searching for an easy way to use up some rolled oats. I wanted something that was salty and barely sweet, so I used salted peanut butter (I really like salty things more than sweet). I didn’t have enough maple syrup, so I made up the difference with brown rice syrup and added about a quarter tsp vanilla after warming the peanut butter/syrup mixture. I also pulsed the oats in my food processor about a dozen times – not to a powder, just roughly chopped because Im not a fan of big pieces of oat. I also didn’t have chocolate chips, so I just left that off (next time!) I can tell, just from snacking on the crumbs, that these will probably be gone by the end of the day. 😉
Thanks, Kayla! Oooh, so much fun hearing about your adjustments! A salty version of these bars sound so yummy. Enjoy!
WOW! WOW! WOW! These were awesome & so easy. We did add a 1/2 c. of gluten free crisp rice cereal for a little extra crunch and texture – DELICIOUS! Thank you!
WOOHOO!!! I’m so happy to hear that y’all enjoyed my recipe! Great idea to add in GF crisp rice cereal. YUM!
Hi Demeter. Thank you for the great recipes. I made these bars a few weeks ago and they came good. Today I made them and did not have as good of results. My oat mixture really fell apart when I cut them. I am enjoying eating the crumbs , but they should be in the crust. I wonder if there was too much peanut butter. I used a cup, but this time it was in the refrigerator so maybe I packed it too much. The topping does not cover the entire area and was hard to smooth out. It was melted enough, but kept lifting the oats. I ended up melting a little more peanut butter and chocolate chips. Next time I am going to double the topping and bring the peanut butter to room temperature before measuring. The taste was good. Do you have any suggestions? I agree with another person’s post in that they are not as thick as yours look in the picture. Thank you!
Hi Maria. Yes, it definitely seems like the peanut butter might be the issue. If it’s too dry, it will change how it intersects with he other ingredients and cause the final mixture to be too dry. Same for using the PB in the chocolate topping. I’d say to try it again with peanut butter that has the natural oil better incorporated. Hope this helps! 🙂
Thank you! I buy organic vegan peanut butter that is only peanuts. Do you refrigerate your peanut butter after opening? Thank you!
can the syrup be replaced with honey? that’s kind of random but i ran out…
Hi Annabelle! Yep, that would work fine here. Enjoy! 🙂
I am allergic to peanuts. Going to try with almond butter!
Hi Bess! Yep, that should work fine. Hope you enjoy the bars! 🙂
Such a perfect combo! Love these bars!
Agreed! 🙂 Thanks Cathy!
