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 No Bake Peanut Butter Cup Oatmeal Bars (Vegan)

One of our favorites? These vegan + gluten free chocolate peanut butter oatmeal bars! They’re made with just 4 ingredients, come together without an oven (wahooo!!) and are dairy-free, protein-rich, vegan and gluten free!

These healthy no bake peanut butter oat bars taste like peanut butter cups. Layer 1: a chewy, sweet peanut butter oat bar layer made with just 3 healthy ingredients. Layer 2: a thick ‘n rich vegan chocolate peanut butter topping. Result: the best chocolate peanut butter oatmeal bars that taste like Reese’s peanut butter cups!

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!
