  • EASY: Just three ingredients for these banana oat muffins- bananas, oats, and baking powder!
  • FLAVORFUL: The ripe bananas have a subtle banana flavor with natural sweetness and no added sugar. You can also upgrade these banana oat muffins with the addition of chocolate chips, fresh fruit, or nuts!
  • HEALTHY: Packed with healthy fiber and no added sugar


This is a photo of the ingredients including oats, baking powder, and overripe bananas.
  • Overripe bananas: You want to use bananas that are spotty and brown (The ones you were about to throw away!) These contain higher amounts of sugar and will add natural sweetness to your muffins. As bananas ripen, their starch turns to natural sugar which is why they are sweeter than their green/bright yellow counterpart.
  • Old-fashioned oats (Rolled oats): You will be grinding your oats into an oat flour using a blender. You can also use quick cooking oats. Do not use steel cut oats for this recipe as they will not blend into a flour easily.
  • Baking powder: This will help our muffins rise. Do not use baking soda as this does not contain the acid component that we need for this muffin recipe.
  • Water: I don’t consider this an ingredient, but you will be adding a small amount of water to your muffins to create the proper texture.

🔪 Step-By-Step Instructions

This is a photo of oat flour in a food processor.

In food processor, add your old fashioned oats and process until it is a fine flour without any large oat pieces. This may take a few minutes.

This is a photo of smashed bananas.

In a medium size bowl, mash your bananas with the back of a fork until there are no large lumps.

This is a photo of the batter mixed together.

Add your oat flour, baking powder, and water to the bananas and mix until combined. At this point you can add in your vanilla and salt. You can also mix in fruit ,chocolate chips, or nuts. Alternatively just sprinkle it on top too (as seen in next picture).

This is a photo of chocolate chips on top.

Grease your muffin pan with a non-stick cooking spray and pour ~1/4 cup of batter into 6 muffin tins. You can sprinkle the tops of the muffins with chocolate chips, nuts, or fruit. I used a spoon to push down some of the toppings.

This is a photo of an overhead shot of the muffins before the oven.

Bake for 15-17 minutes or until the edges are golden brown and a toothpick in the center comes out clean.

This is a photo of a chocolate chip muffin.

Let banana oat muffins cool for 5 minutes before removing from muffin pan. Let cool on a rack for 1 hour before storing.

Hint: I use an avocado oil spray in the muffin pan to grease it before adding the muffin batter. You can also use muffin cup liners if you’d like.


  • Old fashioned oats – You can use quick cooking oats instead.
  • Water – Use plant milk such as soy or almond.


Try adding some fun flavors to your simple 3-ingredient banana oat muffins:

  • Chocolate – add in 1/3-1/2 cup of mini or whole dark chocolate chips for a chocolate flavor
  • Fruit – add fresh blueberries, raspberries, chopped strawberries, and more! If you use frozen I recommend defrosting and draining out the excess liquid
  • Nuts or Seeds– add chopped walnuts (for banana walnut muffins!), pumpkin seeds ground flaxseed, chia seeds, sunflower seeds, and more
  • Nut Butter – add in 1-2 tbsp of peanut butter, almond butter, or sunflower butter for a different flavor.
  • More Sweetener– if you like even sweeter muffins add 1 tbsp of maple syrup with 1 tsp vanilla extract. You can also use brown sguar.

Add a pinch of sea salt to round out the sweet flavor of the muffins.

You can also make these muffins in mini muffin tin (will make ~12 mini muffins).

Let the vegan banana oat muffins cool completely before storing. Store them in an airtight container in the fridge for up to 5 days.

You can freeze these muffins for up ro 3 months in a container or gallon size plastic bag.

Reheat muffins in the microwave (10-15 sec) or in a convection oven (350F for 5 minutes).

❓Recipe FAQs

Is a muffin a healthy breakfast?

These muffins contain no added sugar or processed ingredients. They are a healthy breakfast filled with fiber (which is good for digestion) and other vitamins from the banana.

How sweet are banana oatmeal muffins?

These banana muffins have a mild natural sweetness to them from the ripe bananas. If you like your muffins sweeter, add in a tbsp of maple syrup or consider the addition of chocolate chips or fruit.

Can I use quick cooking oats?

Yes, quick cooking oats work as well. We are grinding our oats into an oat flour in a blender or food processor and quick oats will blend the same as old fashioned oats.

Can I use baking soda instead of baking powder?

No, these have a different chemical composition. Use fresh baking powder that is no more than 6 months old. If your baking powder is older than 6 months you may have flat and/or denser muffins.

Do I need to use muffins liners?

No, you do not need muffins cups however they are helpful to prevent sticking and save on clean-up. You can use a small spray of avocado oil in each muffin tin before adding the batter.

❤️When to enjoy these muffins:

These delicious banana oatmeal muffins can be eaten for:

  • A breakfast at home or on-the-go. Heat it up in the microwave for 10-15 seconds an put some butter, jam, or nut butter on each half.

  1. I’ve been trying to incorporate more vegan meals into my diet and have been craving something sweeter but wanted to stay healthy. These muffin came across my Instagram and I luckily had all the ingredients so of course I make them. They were so delicious and easy to make. Will definitely make again.

  2. 5 stars
    I’ve made them so many times, and they’re always a hit. They’re super easy to make, and so delicious! Plus, they’re healthy too!

  3. 5 stars
    The addition of chocolate chips made these banana oatmeal muffins so decadent. Even the kids devoured them.

  4. 5 stars
    I loved these muffins! They came out so fluffy with the perfect banana flavor. I made them as is, but I love the idea of adding some chocolate chips and macadamia nuts next time.

      1. Okay, thanks. I have seen other banana muffin recipes not use baking powder which is why I was wondering. How much does it rise with baking powder? I wasn’t really interested in adding it since I didn’t want the extra sodium. Will the muffins still be fine, just dense?

        1. I haven’t tried it without the baking powder but you could definitely give it a go! I bet they will just be a little more dense. Let me know how they turn out if you try it that way 🙂

  5. I have seen that ripe bananas can be substituted with applesauce. Have you every tried doing 50/50 applesauce and bananas? How much would you use of both?

  6. 5 stars
    This was perfect for some pretty brown bananas I had kicking around. Who doesn’t love a banana oatmeal muffin? These turned out so good for only 3 ingredients.

  7. 5 stars
    Ok, I was a bit skeptical about these three ingredients, but these Banana Oatmeal Muffins turned out perfect. Making that oat flour was simple, too. I added dried cranberries and walnuts to the batter. I will be making these again.

  8. 5 stars
    These banana oatmeal muffins were so easy and a huge hit with my grandkids. I’m always looking for treats to make for them with no sugar and they loved these muffins. I added some sugar free chocolate chips in them and they LOVED them!
