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!

Ingredients 

Peanut Butter Oat Bars

Vegan Chocolate Topping

Instructions 

  • Line an 8-inch square baking pan with parchment paper or wax paper. Set aside.
  • Make the Peanut Butter Oat Bars: In a medium, microwave-safe bowl (large enough to add oats later), add peanut butter and maple syrup. Whisk together until well-mixed. Heat in 20-second increments in the microwave until warm, fragrant and thickened. Whisk in between heating increments.
  • 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.

      Thanks Natalie! Enjoy!!

  3. Steph says:

    I loved these! I was skeptical . at 4 ingredient and no-bake, but they were amaze! These totally classify as breakfast in my house, thanks for the new obsession, will be cruising your site for more!

      Hiya Steph!! Hehe… glad to hear skepticism made way for YUM!! Oooh, having these for breakfast is the BEST idea! Can’t wait to see what you try next. 🙂

    Oh my gosh! I can eat dessert again! I’m allergic to dairy, eggs, gluten and cane sugar! I will be using your recipes all the time now.

  5. Tracy says:

    These look so good! My favorite flavors – chocolate and peanut butter – with oats thrown in! Also, quick and easy, what more can you ask for?! I can’t wait to make them for my kids (my daughter is vegan) – they look like a great snack. Thanks!

    1. Demeter | Beaming Baker says:

      Thanks Tracy! Right? It’s so hard to resist the combo of chocolate, pb and oats. 😉 Can’t wait to hear what you two think! 🙂

    Very good! I used crunchy peanut butter with the oats and creamy peanut butter with the chocolate. The crunchy peanut butter adds a nice crunch to the bars. I was disappointed in how thin they are. I used as 8 inch pan but my bars were about 1/4 an inch and the oat mix and chocolate topping were equal. Next time I will double the oat mix. Otherwise, very delicious!

    1. Demeter | Beaming Baker says:

      So happy to hear you enjoyed these, Brooke! Definitely go for double if you like them thicker. Enjoy!

  7. Kristin says:

    do you have the nutritional information?

    1. Demeter | Beaming Baker says:

      Hi Kristin, not yet! I’m slowly, but surely working my way through adding that info to the site. There are nutritional calculators online. Good luck! 🙂

  8. Nancy Morin says:

    I’ve got instant oats. Is that the right thing or do I need something different?

    1. Demeter | Beaming Baker says:

      Hi Nancy, you’ll actually need rolled oats, which are also called “old-fashioned oats.” The instant oats you have might work, but no guarantees since that’s not what I developed the recipe with. Let me know how they turn out! 🙂

    This looks great!

    These are delicous but the picture is wrong. I used an 8 x 8 dish as stated in the direction but my bars were not as thick as seen in the picture, these were a measly 1/3 of an inch high. The picture makes them look like they are 3/4 – 1″ inch in height. If I knew they would be so thin I would have easily doubled the batch. Oh and I did sprinkle some sea salt on top for a little kick.

    1. Demeter | Beaming Baker says:

      Glad to hear you enjoyed them! Good idea to increase the batch to your liking, and to add the sea salt. Enjoy! 🙂
