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.


And if you know a little bit about us, you’ll probably guess that our following recipe won’t just be entirely plant-based and made from easy to find ingredients, but also wholesome and nutrient-dense.

We think that the internet and cookbooks are already full of unhealthy or semi-healthy recipes that we would only make on very special occasions. And even then, we’d prefer to choose the more nourishing version.

Therefore, it’s close to our heart to share with you every day healthy recipes that you can enjoy on a regular basis without them having to be a treat.

Depending on what kind of consistency you like your oatmeal breakfast bars to come in, you may be very happy or very unhappy with our recipe. To be honest, both the crunchy and moist versions require quite a bit of added oils, so our recipe offers a rather chewy mouthfeel.

And, depending on your add-ons of choice, you can tweak them to be more on the sweet and moist side (think dates or other dried fruit) or a lot more crunchy by topping them with nuts and seeds.

What we wanted to provide you with here is just a very simple base for such breakfast or snack bars which you can then modify to suit your taste and nutritional preferences.

Some want to keep them lower in added fat, others want them to be a good Omega-3 source. You could even go crazy on the spices and add pumpkin spices or cacao powder, some vanilla extract or even chili!

For a colorful springtime version, add some berries to the batter at the very end – you’ll get a nice dose of antioxidants that way as a bonus. I imagine you could also add chopped apple or pear during the colder months. Or sprinkle a few dark chocolate chips or cacao nibs on top!

Preparing Vegan Oat Bars

One of the main problems we hear from our readers is that it’s so hard to find quick and easy recipes. Those that are filling, that the whole family will enjoy, and that you could even take with you to work or school.

Luckily, our vegan oatmeal bars don’t require any real kitchen skills, can be prepared in bulk and eaten over the course of the week – and they don’t break the bank.

Curtting Vegan Oat Bars

The complex carbohydrates keep your blood sugar stable and your body out of the hunger zone for a few hours (depending on how much you eat, of course).

Oats are a great fuel for your brain and gluten-free, for any of you who cannot digest this plant-based protein. We always use soy milk at home because we like the nutritional values, consistency, and taste the most (as well as the price tag!), so this is what you’ll see in our recipes.

But in the case of the vegan oat bars, simply swap it for any other plant-based milk you prefer! Doesn’t make a difference.

For a more convenient version, you can use whatever whole grain flour you have at home instead of the ground up oat flour. Even though it’s made within a couple of seconds using a good blender, you might not have access to this kitchen tool or simply cannot be bothered.

Making them with some whole grain flour, even all-purpose flour, instead, will give you a different consistency but they will still be healthier than any store-bought ones you might find.

Because let’s face it, with all these added sugars, oils, and isolated plant proteins, you’re more often than not confronted with a junk food disguised as “protein bar” or “granola bar”. Many of them are also sweetened with honey, which is not even vegan. 

Eat Vegan Oatmeal Bar

Not to hate on store-bought products in general, we just think it’s a better idea to nourish your awesome body with every bite you take. Because every time you put some food into your mouth, it’s a chance to miss out on an even healthier one, as Dr. Michael Greger likes to say.

If you’re into healthy and delicious oat-based snacks or breakfast options, you can also try our vegan blueberry muffins that are free from oils and refined sugar! A great way to make your eating pattern healthier is by having such homemade treats and snacks in your kitchen so you don’t go for store-bought items too often.

Now, let’s go straight to the simple vegan oatmeal bar recipe!

Healthy Vegan Oat Bar Recipe (Gluten-Free)

These easy Vegan Oat Bars are made with just a handful of simple and wholesome ingredients, naturally gluten-free - no oil, no refined sugar, just 100% satisfying deliciousness.

Course Breakfast, Dessert, Snack
Cuisine Vegan
Prep Time 10 minutes
Cook Time 20 minutes
Total Time 30 minutes
Servings 12 pieces
Calories 143 kcal


Dry Ingredients

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

Wet Ingredients

  • 2 ripe bananas, chopped or mashed
  • ½ cup soy milk (can swap for other plant-based milk)
  • 1-2 tbsp maple syrup

Optional add-ons

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


  1. Preheat oven to 350F/180C. Prepare your non-stick baking dish 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 1.3 cups (or 120g) 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. Stir for a few seconds with a spoon. In a different bowl, mash or chop your ripe banana and mix in the soy milk and maple syrup with a fork, mixing thoroughly. 

  4. Now, pour the wet ingredients on top of the dry ones and combine well. You can add any nuts, seeds, or dried fruit here if you like.

  5. Put your mixture on to the parchment or baking dish, spreading it evenly. The bars should be 1-1.5 inches (3-4 cm) high. Finally, sprinkle the toppings of your choice on the oat mixture and 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.

  6. Place dish on a cooling rack for 10 minutes, then slice into bars. You can store them in an airtight container for a couple days, or wrap them individually into parchment paper and freeze them in a container for up to 3 months.

  1. Hi,
    I made the bars bur they did not look like yours, more like a solid cake. I weighed the rolled oats and oat flour. The weight of the rolled oats was equal to 1 cup but 1 cup of oat flour weighed 96 grams only. So when using 220 grams as in the recipy, the mix became very dry and more like a cake dough. I had to adjust with some more soy milk. Next time I will try to use 1 cup of oat flour only. Maybe you can check if 220 grams is correct.
    Regards Ågot

    • Hey, thanks so much for your feedback! You’re totally right, the 1 cup of flour doesn’t come down to 220 grams… not sure why I jotted down that number. I’m so sorry about this but luckily you kind of saved it by adding some more soy milk. Will change this asap.
      Any way I can make it up? ;)
      Warm wishes,

  2. I just made these, very tasty! I wasn’t sure what size pan to use. A 9×12 seemed like it would be too big of a pan for the mixture to be 1-1.5 inches high. I bet a 8×8 pan would be perfect. The only thing I had beside a cake pan was a round cake pan, so I used that. I will definitely make again, thanks for sharing! The add in possibilities are endless lol.

    • Thanks so much for the wonderful feedback! Sorry it wasn’t very clear what pan to use, smaller ones definitely work better. Will add it to the article :)

  3. I just tried the recipe and I loved it. I used peanuts, walnuts and chocolate as toppings . They only got around 2cm high though, but they taste delicious and I can’t wait for them to cool!

  4. Just made this recipe, it’s amazing! I made a few changes, such as:
    I added vanilla extract to the wet ingredients
    I mixed in some chopped almonds, dried cranberries, chia seeds, and pumpkin seeds
    I added extra cinnamon; in the recipe and as a topping.
    Will definitely make these again, thanks for the recipe.

  5. Hi I wanted to know what would happen if I didn’t add the baking powder? I have all the ingradients on hand except the powder. Thank you!

  6. As far as the calories are concerned, is it 143 cal. per bar? or is that for the 12 servings that the recipe makes?

  7. Just made these,delicious! Thank you so much for the recipe! I omitted the maple syrup and added the five dates to the milk and blended them together. Used five large dates. Added all the optional add-ons when mixing the dry and wet ingredients together. Except no more dates. Baked 20 minutes in an 8by8 parchment paper lined baking dish. Very filling and tasty! Hoping my son will grab some for breakfast.

  8. Hi Alena, the photos look like you mixed the chia seeds in with the mixture?
    I made these today and topped it with dates, walnuts and coconut, they were delicious,I opted to use water instead of milk .

    • Thanks so much for the feedback – yes, you can either put the chia seeds and other add-ons into the mixture itself or top the oat bars with them! Sorry if that step caused any confusion :) And sure, you can just make them with water!

    • you can use any other grain flour, I’m very sure! Haven’t gone through all of them but whole wheat, spelt, all-purpose, all of them should work. Not sure about things like almond flour, though.

  9. Hi, I just made these bars and they were delicious. I normally don’t bake but am sick and was craving comfort food. I had all the ingredients on hand; added chia, dates and walnuts to the mid. I blended 1.3 c oats and measured out one cup for the recipe. 8×8 Pan. So easy and fast. And filling. These will be great to bring into work for an east breakfast. Thank you for sharing the recipe!!

  10. Thank You! Just made these and they are not only perfect as a great snack or quick meal but so healthy and yummy! I used the majority of two very ripe bananas and added a little unsweetened applesauce. Also, mixed almond milk instead of soy (since that’s what I had). For extras I put in six diced prunes, chopped almonds and chia seeds. I did use an 8×8 baking dish and increased the baking time to 23 mins. Very moist and chewy. Will definitely make again and play with different “extras”. :)
