- 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
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.
In a medium size bowl, mash your bananas with the back of a fork until there are no large lumps.
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).
Grease your muffin pan with a non-stick cooking spray and pour ~¼ 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.
Bake for 15-17 minutes or until the edges are golden brown and a toothpick in the center comes out clean.
Let 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 ⅓-1/2 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 tablespoon of peanut butter, almond butter, or sunflower butter for a different flavor.
- More Sweetener- if you like even sweeter muffins add 1 tablespoon of maple syrup with 1 teaspoon 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).
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.
These banana muffins have a mild natural sweetness to them from the ripe bananas. If you like your muffins sweeter, add in a tablespoon of maple syrup or consider the addition of chocolate chips or fruit.
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.
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.
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.

Try out these other delicious breakfasts:
- How to make your bananas ripen faster: Place the banana in a brown paper bag with another ripe fruit such as an apple or avocado. Loosley fold up the bag. The ethylene gas will help your banana ripen much faster (1-2 days quicker).
- How to tell when your muffins are done cooking: The outer edge should be golden brown. Insert a toothpick in the middle and if it comes out clean your muffins are done.
- These are tender muffins but still have a fluffy texture. If you want them even fluffier add in an extra ¼ teaspoon of baking powder.
