Breakfast bars come in all shapes and sizes. From crunchy to chewy, soft, fruity, or nutty – we love all variations of this convenient and tasty snack. But beware: not all oat bars are vegan and not all vegan oat bars are healthy.

To show you that it’s actually really easy to create oatmeal bars that are both healthy and vegan, we want to share this family and fan-favorite with you here.

Because nothing calls our name more than a cheap, convenient and wholesome twist on a comfort food recipe!

That’s why our baked vegan oat bars don’t just contain rolled oats, but also natural sweeteners in the form of fruit, some plant-based omega-3 sources and are entirely oil-free!

They’re a homemade convenient snack that’s not just eggless but could also be made flourless by replacing the oat flour with quick oats.

Some of the reasons why we love this recipe so much are that our gluten-free oat bars are not just perfect for meal prep and an easy make-ahead breakfast option, but also control blood sugar, offer some stable energy – and, most importantly, are irresistibly chewy and delicious!

To see how versatile our healthy oat slices are, what you need for them, whether they are good for you and lots of tips around making the best oat bars, keep on reading.

Vegan Oatmeal Bars Ingredients

Are Oat Bars Healthy?

Well, this depends highly on the ingredients used for the oat bars. In our case, we make sure all of the components in our recipes are as healthy as it gets while still being delicious, easy to make and budget-friendly.

Many commercial brands at the store have a lot of added sugar and fat in their oat bars – even if you’re looking for popular oatmeal bar recipes on the internet, they can call for butter or coconut oil, sugar, syrup and eggs… none of which would fit our definition of “healthy”.

6 Reasons Why Oil Isn’t A Health Food

On the other hand, if you focus on whole food and plant-based ingredients, such as rolled oats (of course!), banana or dates for sweetness and nuts or seeds for protein and healthy fats, you’ve got yourself a pretty darn healthy and nourishing snack!

What Are the Healthiest Breakfast Bars?

We get that question a lot, and our response is always that the more whole food-based a breakfast bar is, the better. It always depends on someone’s current diet and what adjustments they are open to make!

Keeping your oat bars vegan already eliminates the potential butter, eggs and honey. If you then swap the coconut oil for nut butter or fruit puree (both are easy oil-free baking swaps), that’s another step – and keeping the vegan oatmeal bars free from added sugar would be best, too.

That being said, our easy whole food plant-based recipe for breakfast bars below ticks all of these boxes and is a great healthy snack! It’s one of our most popular recipes on the blog, and if you think we might be biased because it’s our own creation, check out what so many of our readers have shared in the comments below.

In general, it’s important to have an overall healthy eating pattern, and adding some richer treats and snacks will probably be no problem! Check our following in-depth article for more.

How to Make Vegan Oatmeal Bars

As fancy as they might look on photos, making oat bars is actually really easy. You need:

  • Five basic ingredients (plus some baking powder)
  • Two mixing bowls for the dry and wet ingredients
  • One spoon
  • One 8×8 baking dish (non-stick or lined with parchment paper)

It’s a really good recipe for beginners because it’s almost impossible to mess up (unless you manage to burn them, which may or may not have happened in our own kitchen a couple of times due to multitasking experiments).

Even if you don’t end up with the perfect texture and they end up all crumbly, just put the pieces into a bowl, add some fresh fruit and plant-based milk and you got yourself a delicious breakfast!

Speaking of consistency, our vegan oat bars are definitely on the chewy and moist side as opposed to being really crunchy. If that’s not your scene, you can add a whole bunch of nuts for a crunchy texture – which can actually be a great variation on this nutritious favorite!

Our healthy oatmeal bar recipe makes for a simple base which you can use to completely modify to your needs (more on that later). Let’s see what you need to make them!

Ingredients for Our Gluten-Free Oat Bars

  • Rolled oats – obviously. They can double up as oat flour if you process them in a blender!
  • Bananas – nice and ripe for more sweetness; mash them to create a creamy consistency that replaces oil and eggs in baking!
  • Soy milk – more nutrients, more plant-based protein, more creaminess!
  • Cinnamon – cheap, healthy, cozy and versatile spice that we put in almost all sweet recipes!
  • Maple syrup – just a spritz, can be adjusted to taste and swapped for a different vegan sweetener

If this seems a bit too basic for you, we totally get that. As we said, this creates a healthy and versatile base for all the delicious, colorful, crunchy or chewy add-ons you want to go for!

In our recipe below (and seen in our pictures) are our personal favorite toppings: coconut flakes, chia seeds, walnuts and dates.

We have lots more great ideas for tasty breakfast bar ingredient ideas which you’ll find below! 
In case you want to swap the maple syrup for honey, you won’t end up with fully vegan oat bars – should you be interested in learning more about honey and why vegans avoid it, here’s a great article by The Vegan Society.

Tips for the Best Healthy Oat Bars

In our recipe below, we instruct you to add the toppings, well, on top of the oat bars. This makes them look pretty but can cause the coconut flakes and chia seeds in particular to fall off.

That’s why you can just mix them right into the batter instead! And please, do get creative with the add-ins.

To ensure the oat bars are 100% gluten-free, you need to make sure your oats are labeled as such and are not contaminated with glutinous grains.

If you don’t mind gluten (keep in mind, for the majority of people glutinous whole grains are very health-supporting) and don’t have oat flour on hand or don’t have a blender to create it, simply swap it for another grain flour. You might end up with a slightly different consistency but they are still amazing!

How to Store Oatmeal Bars

What I love about these vegan oat bars is that they are perfect for meal prep! You can make a batch of them and then store covered on the counter for 3-4 days at room temperature or in a food container in the fridge for up to a week.

You can also freeze them, wrapped individually and stored in a freezer bag or food container. They will keep for at least 2 months and are an easy grab and go food! Allow them to sit at room temperature for at least 30 minutes to defrost before eating (or a bit less if you’re up for a very cold oat bar).

Overall, this makes them a healthy and convenient snack option, perfect for school or work as a gluten-free lunch box addition or as a quick breakfast option.

Low-Calorie Snack Bar Tips

To make our oat bars even lower in calories and weight-loss friendlier, you can swap the oat flour for instant oats (making the oat bars a bit more wholesome) and play around with the add-ons.

Lowering the overall calorie density is the best approach to healthy weight management, so the whole food plant-based ingredients in our easy oat bar recipe already fill that bill.

But there’s always some room for improvement!

Instead of the higher-fat add-ons, you could use some dried apple or frozen berries, which you can mix right in with the batter. They both offer fewer calories, a good amount of fiber, essential nutrients and some natural sweetness – meaning you can also omit the maple syrup.

Depending on your usual snack choices, our vegan oat bars as written below are probably already comparably low in calories and more nourishing, too!

If you want to go out and buy low-calorie snack bars, make sure to check the label for added oils and sugars (both of which will be super common). Choose those that are made with as many whole food ingredients as possible!

Healthy Vegan Oat Bars

Yield: 12 pieces
Prep Time: 10 minutes
Cook Time: 20 minutes
Total Time: 30 minutes

These easy vegan oat bars are made with just a handful of simple and wholesome ingredients, naturally gluten-free, oil-free and refined sugar-free. They're a great homemade treat, breakfast or snack, whole food plant-based and easily customizable. Kids and adults alike love them!

Ingredients

Dry Ingredients

  • 1 cup rolled oats (90 g)
  • 1 cup oat flour (120 g)
  • 1 tsp cinnamon
  • 1 tsp baking powder
  • ¼ tsp salt

Wet Ingredients

  • 2 ripe bananas, chopped or mashed
  • ½ cup soy milk
  • 1-2 tbsp maple syrup

Optional Add-ons

  • ⅓ cup walnuts, chopped (40 g)
  • 5 dates, chopped
  • ¼ cup coconut flakes (20 g)
  • 2 tbsp chia seeds

Instructions

  1. Preheat oven to 350° F (180° C). Prepare your non-stick baking dish (around 8x8) or line it with a piece of parchment paper so the bars are easier to lift out.
  2. If you quickly want to make your own oat flour, put 1 ⅓ cups (or 120 g) rolled oats in your blender or food processor and blend or pulse them. 
  3. In a large bowl, combine all of the dry ingredients: your oats, flour, baking powder, cinnamon and salt. Mix with a spoon.
  4. In a different bowl, add the mashed banana, soy milk and maple syrup. Mix thoroughly with a fork.
  5. Now, pour the wet ingredients on top of the dry flour mixture and combine well. You can add any nuts, seeds, dried fruit or add-ins of choice here if you like.
  6. Put your mixture onto the parchment or baking dish, spreading it evenly. The bars should be 1-1.5 inches (3-4 cm) thick.
  7. Finally, sprinkle the toppings of your choice onto the oat mixture, press them down gently, then bake for around 18-20 mins until firm and lightly golden. The baking time depends on how thinly you spread your batter and how soft or crunchy you want them to be.
  8. Once the oat mixture has turned golden, remove from oven. Place the baking dish on a cooling rack for 10 minutes, then slice your oat batter into bars. Enjoy warm or store in a container and eat over the next few days!

Notes

  • You can store the oat bars in an airtight container for 3-4 days on the countertop or up to one week in the fridge. To freeze them, wrap each oat bar individually into parchment paper and place in a container where they will keep well for at least 3 months in the freezer.
  • If you don't want to use soy milk, simply replace it with any other vegan milk alternative.
  • For a smoother texture, use only oat flour (1.75 cups or 210 g) and no rolled oats.
  • You can swap the ripe banana for applesauce if you want.
  • Feel free to either omit the maple syrup or swap it for another vegan sweetener, such as brown sugar or date syrup.
  • If you need the oat bars to be 100% gluten-free due to intolerances, make sure to go for certified gluten-free oats.

  1. Thank you! This has become a staple item for grab-and-go breakfasts and lunches. We doubled the recipe and use a 9×13 pan lined with parchment, keep the maple syrup measure low, use unsweetened almond milk, and add raisins and walnuts. We add the raisins with the almond milk to help break the sticky goodies up. Sometimes, the bananas were peeled, mashed lightly, then frozen/thawed for shopping convenience. I bought a pack of six oat flours to make it easier for weekend food prep, although at first was making our own oat flour. 23 minutes at 350 oven.

  2. This recipe is amazing!
    It’s super versital. The first time I made it was with the coconut and dates.
    This last time I did dates and craisins, and drizzled melted vegan chocolate I had left over from a different recipe over the top.
    This is a recipe that is just plain good in it’s own right (not a good-for-gluten-free-vegan).
    Thank you!

  3. How long would you estimate they will last in the refrigerator? I’m trying to decide whether to freeze or not. These are delicious and have a thick, satisfying bite to them! Thanks for sharing!

    • They are too yummy to last for more than 3 days in our fridge, haha! I’d give them 4-5 days or so but haven’t actually tried – would love some feedback if you decide to do so :)
      Very happy you like them!

  4. Um, these oat bars are such a great way to kickstart the morning. Not to sweet, customizable. Like seriously so easy and delicious. I added all the suggested add-ins and drizzled my bars with peanut butter and honey. CAN YOU SAY YUM! I love love these oat bars.. Will be making these regularly.

    • Hey Sophia,
      thanks for the question! Since this is a recipe for vegan oat bars, we went for maple syrup as the sweetener – honey is an animal product and therefore not considered vegan :) However, if you want to use it, I assume it’s just as sweet as maple syrup so swap for the same amount!
      Hope you’ll enjoy this recipe.
      Best wishes,
      Alena

  5. Wow. These are the first oat bars I tried and they’re already my favourite recipe. I made some with walnuts, dates and almond butter and some with cashews and dried apricots. Yummy!

  6. I made these tonight. They are amazing! I used my almond flour because I have tons of it and they turned out great. Awesome recipe, thanks!

    • depending on the amount you want to use, swap it for some of the wet ingredients like the plant-based milk. It won’t change the baking time, no :)
      Let us know about your creation, we always love a good oat bar idea!

  7. Hi! My boyfriend is allergic to bananas. Do you know of any other wet ingredient we could substitute for? Thanks!

    Reply
    • yes, use some applesauce or nut butter instead! Cannot tell you the exact amount right now but you’ll notice once the right texture of the batter is created :) Let us know how they turn out!

      Reply
    • Hi Meg, they’ll probably turn out only slightly different when omitting the baking powder :) I think I never tried doing it so I’d be happy to know how they turn out!

      Reply
  8. Unfortunately this wasn’t a hit for me. I made it with
    1 cup rolled oats (90 g)
    1 cup plain flour (120 g)
    1 tsp cinnamon
    1 tsp baking powder
    ¼ tsp salt
    Wet Ingredients
    2 bananas, mashed
    ½ cup almond milk
    1-2 tbsp honey as I had no maple syrup
    ⅓ cup walnuts, chopped (40 g)
    ¼ cup coconut flakes (20 g)

    Perhaps the key is over ripe Bananas as mine were just yellow and the maple syrup. My slice mostly tasted like flour and cinnamon. I’ll probably try to use maple next time, please extra ripe bananas perhaps some sultanas and vegan butter.

    Reply
    • sorry to know they didn’t turn out so well! Yes, we always use very ripe bananas. These oat bars are one of our most popular recipes on the blog, so I’m not sure what happened in your case — perhaps the maple syrup would be sweeter than honey. Since you left out the dates, that’s also some natural sweetness that was missing ;) swapping them for sultanas would be great! Sure, you can use some vegan butter, our recipes just follow the wfpb guidelines which is why they are refined fat free. Let us know how they turn out!

  9. Hi there,
    Hoping to try to make these in the next couple of days – just wondering if you can swap out the oat flour for GF all purpose flour and if so how the conversion would work.
    Thank you!

    Reply
    • Hey Erin,
      thanks for your comment! I actually never tried this but I’d swap it for the same amount in weight and see whether I end up with a good consistency of the batter or if I’d need to adjust with some more or less liquid, for example.
      Pretty sure you will create delicious bars, this recipe is hard to mess up ;)

      Reply
    • Hey Nany,
      I’ve made them before with some frozen raspberries mixed into the batter before baking but not yet with a whole layer of frozen berries — in the article, I linked to a recipe by Hummusapiens who created something that you might be looking for :)
      Best,

  10. I just started a new job and wanted a healthy breakfast I could eat during the long commute, these came out great!! Super easy recipe and easy to change up depending on what you have. Mine reminded me of a cross between banana bread and carrot cake.

    I roughly doubled the recipe and added in some extra walnuts, chia seeds and chopped dates in the mix, plus desiccated coconut on top.

    Reply
    • sure, they can be replaced with applesauce but you might need some additional sweet ingredients, either more dried fruit or some maple syrup if you want :)

      Reply
  11. So happy I found this recipe! It is perfect as is. You can also do just about anything with it and it turns out great. You can make it more cakey or more bar like and put just about any mix in you can think of.
