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!

  • Add oats. Stir and fold until thoroughly combined. Pour this mixture into the prepared baking pan. Using a rubber spatula, smooth into an even, tightly-packed layer. Set aside.
  • Make the Vegan Chocolate Topping: Use the double boiler method or do the following. In a medium, microwave-safe bowl, add Chocolate Topping ingredients. Heat in 20-second increments until softened and melted. Stir until smooth.
  • Pour this chocolate mixture over the bars. Using a clean rubber spatula, smooth into an even layer.
  • Freeze for 30-40 minutes, or until firm. Remove from freezer and slice into 16 bars. Enjoy! Storing instructions below.

    Can you use peanut butter powder (pb2) re-hydrated in place of the unsalted pb? I can’t find unsalted pb in my town. OR can you use the salted?

    1. Demeter | Beaming Baker says:

      Hi Kim, use the salted peanut butter. That will work, but just add a bit of saltiness to the bars. Enjoy! 🙂

    Thank You for sharing your 4 ingredient bar recipe! I was looking for something like this for days. I was skeptical at first, but I followed your directions and wow! I took some with me hiking today, sitting on a mountain, gratefully eating my bar, thinking how happy I was I made these and thankful you would share such an awesome, simple and humane recipe!

    1. Demeter | Beaming Baker says:

      Aw, thank YOU, Zoë, for taking the time to leave such a wonderful comment. You pretty much described the perfect day right there. It totally gave me all the good vibes imagining that moment. Thank you for sharing that. Hugs!

    I didn’t have maple syrup so I used agave, and for the topping I used regular p.b. and chocolate p.b. and added chocolate chips on top.

    1. Demeter | Beaming Baker says:

      Awesome! Thank you for letting me know about those subs. I’ve always wondered about agave and regular PB. Hope you enjoyed them, Gigi! 🙂

    Decided to do half honey, half syrup + added 1/3 cup chopped sea salt almonds, and dark choc. vegan chips….. SO GOOD– adds a little crunch too!

    1. Demeter | Beaming Baker says:

      Oh gosh, that sounds INCREDIBLE, Nicolette! I love the sound of those sea salt almonds. Thanks for letting me know how these turned out for you! 🙂

  5. Kim says:

    These sound easy to make and amazing! I am going to have to try them out! Thank you!

    1. Demeter | Beaming Baker says:

      They’re SO easy to make! Can’t wait to hear what you think, Kim! 🙂

  6. Nicolette says:

    Did honey instead of syrup and only 1/4 cup + added a mashed banana!!! Tastes great, just a little greasy

    1. Demeter | Beaming Baker says:

      Adding in mashed bananas sounds awesome, Nicolette! I’ve got to try that some time. 🙂 Enjoy!

    The recipe looks delicious but I’m just struggling with the pee proof underwear ads showing up in the midst of it all. Kind of spoils my appetite. But once I can get that image out of my head I’ll whip up a batch.

    1. Demeter | Beaming Baker says:

      Oh no! Sorry about that, Cary. I don’t have editorial pick of the ads that appear (unfortunately lol). Hopefully it’s all gone from your mind now. Can’t wait to hear what you think (about the bars, not the You Know What). .

    This looks great. I’m going to make them for the kids on our road trip. However, I’m going to cheat and use regular oats and good old fashion chocolate chips. Hopefully, they turn out just as good.

    1. Demeter | Beaming Baker says:

      Ooooh, what a great idea Julie! Sometimes snack cravings hit the strongest on the road! Lol on cheating–as long as it works for you and makes you & the fam happy, that’s all that matters. ❤️ They’ll turn out just fine! Can’t wait to hear what you think. Have a safe & fun trip. .

  9. Jaclyn says:

    Curious: What peanut butter do you use? All the “healthy” ones I find are still really grainy–even though they’re called “creamy”! Thank you!

    1. Demeter | Beaming Baker says:

      Hi Jaclyn! I switch between a variety of brands, and I always unsalted: Crazy Richard’s, Trader Joe’s brand, Whole Foods’ 365 brand. Hope this helps! 🙂

  10. cakespy says:

    YES, YES, YES, YES, YES. These include all things wonderful and delicious and I want to eat them right now.

    1. Demeter | Beaming Baker says:

      Woot woot!! Hope you get to try and just love it! 🙂
