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!

  • 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.

    It has been way too long since I’ve visited and commented on this beautiful spot on the internet ;). Of Course, social media, but I don’t get your amazing commentary there!! These bars are totally winning the game. ALSO it is 101, YES, 101 degrees in Jamaica so no bake is DEF where I’m at!! Saving these beauties to try, D!

    1. Demeter | Beaming Baker says:

      Aw… you’re the sweetest, J! <3 <3 I cannot believe that it's that hot in Jamaica!!! Wow!!! It was raining nonstop in Boston for ages, but now it's finally cleared up. Here's to us enjoying all this beautiful weather with a bunch of no-bake goodies! 😉

  4. Gayle @ Pumpkin 'N Spice says:

    Four ingredient bars? No-bake? Sign me up! I feel like I say this every time, but you are the queen of no-bake, simple ingredient treats. Thees sound amazing! I’m ALL about that peanut butter and chocolate combination. In fact, I know that my husband might just eat these all before I get to them. So perfect for the summer too, especially since it’s been so hot here. Pinned of course! Hope your Tuesday is off to a great start!

    1. Demeter | Beaming Baker says:

      Done and done! Keep saying it, because who wouldn’t want to be the queen of no bake? 😉 Thanks so much Gayle! Hope you and the hubster can whip up a batch and just love it! Have a great week!

    Hello! I’m on the hunt for lactation recipes but am struggling to find any decent ones. Do you think I could add brewers yeast to this without ruining them?

    1. Demeter | Beaming Baker says:

      Hi Ada! Hmm… I’m not sure since I haven’t tried using brewers yeast myself. I’d suggest adding 1 tablespoon in with the oats and seeing how they taste. If it’s still good, you can try another batch with 2 tablespoons. Experiment and see how you like it. Hope this helps! Can’t wait to hear how they turn out. 🙂

And half of them I can’t even pronounce!! 🙂 Lucky for all of us, we have you and your genius brain who creates MAGICAL things like these oatmeal bars! For realsies. FOUR ingredients PLUS no baking AND PB+Chocolate. These are like the unicorn of oatmeal bars! Te-he-te-he! What’s not to love?! Pinned of course! Cheers, sweets.

    These bars look absolutely scrumptious! And so they should be, they’re made with chocolate, peanut butter, and oats! Everything I love in a granola bar! 🙂 Hope you have a great week, Demeter! xo

    1. Demeter | Beaming Baker says:

      Thanks Marsha! 🙂 That’s all you really need to make a granola bar tasty, right? 😉 Hope you have an awesome one, Marsha! xo

  9. Natalie | Feasting on Fruit says:

    Granola bars that are too soft to be called granola bars sounds like a very good problem to have. Like the kind of problem that I could see ending in me eating an embarrassing amount of this “unacceptable” peanutty oat batter. But transforming them into a new fantastical wonks-would-be-proud chocolate-topped granolssert and sharing them with the world is SO much better a plan! Me and my dog need to whip these up ASAP. And best part about doggy sidekick is she can’t have chocolate so you know what that means…all for MEEEEEE. Kay fine, I’ll leave some sans chocolate for the peanut-loving pooch. Happy monday!!

    1. Demeter | Beaming Baker says:

      Hehe. Right? Sometimes the crunchy ones make me feel like I’m gonna break my teeth! Also, what a fun way to “have to” eat all the peanut butter and oats. 😉 Can’t wait to hear what you and your dog think (except for the chocolate part lol). 😉 Happy Monday my dear! <3

  10. Patrick@looneyforfood.com says:

    So easy, simple and delicious! These sound dangourus to have around! So pretty as well!

    1. Demeter | Beaming Baker says:

      Thanks Patrick! Yes, they are a bit dangerous to have around. 😉 Hugs!
