Vegan blueberry banana oat muffins are one of those recipes I make whenever ripe bananas start staring at me from the kitchen counter.
I often turn overripe bananas into low-sugar bakes like my date banana muffins, pumpkin banana muffins, buckwheat flour banana muffins, and these two banana muffins that never fail.
These muffins are tender, moist, and lightly sweet, with warm oat flavor and pockets of juicy blueberries throughout.
They're easy, portable, and ideal for meal prep - great for busy mornings or snack breaks on the go.

🍌Ingredients

- Blueberries: I used frozen blueberries, but fresh work just as well (no need to thaw if using frozen).
- Rolled oats: Rolled oats add a nice chewy texture.
- Bananas: Use ripe bananas for natural sweetness.
- Flour: All-purpose flour works best, but whole wheat or spelt can be used.
- Sugar: I opted for cane sugar, but granulated or brown sugar works just as well
- Vegetable oil: Use any neutral vegetable oil to keep the muffins moist.
- Baking soda + vinegar: This helps the muffins rise and stay fluffy.
- Vanilla: Enhances the overall flavor.
- Dairy-free milk: I used unsweetened almond milk, but any non-dairy milk works.
- Salt: A pinch of salt brings everything together.
As always, you can find the full recipe with a list of ingredients with measurements in a printable recipe card at the end of this post.
🥣How To Make Blueberry Banana Oat Muffins

Step 1: In a large bowl, whisk together the dry ingredients: flour, rolled oats, sugar, baking soda, and salt.

Step 2: Add the mashed bananas, vegetable oil, plant milk, vanilla, and vinegar, then mix until just combined. Do not overmix to keep the muffins light and fluffy.

Step 3: Gently fold in the blueberries until evenly distributed.

Step 4: Preheat your oven to 350°F (180°C) and line a 12-cup muffin tin with paper liners. Divide the batter evenly between the cups, then top with extra blueberries and a sprinkle of rolled oats if desired.

Step 5: Bake for about 30 minutes, or until a toothpick inserted into the center comes out clean. Let the muffins cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before enjoying.

📋Variations
- Nutty crunch: Add ½ cup chopped walnuts, pecans, or almonds for extra crunch and flavor.
- Cinnamon swirl: Mix 1 teaspoon cinnamon (or pumpkin pie spice) into the batter for warm, cozy notes.
💡Marinela's Tips
- Banana amount: Use 1 cup of mashed banana. Using more or less can change the muffins' texture.
- Don't overmix the batter: Stir just until combined. Overmixing makes muffins dense instead of light and fluffy.
- Use ripe bananas: The riper, the sweeter. They add natural sweetness and moisture without extra sugar.
- Measure flour properly: Spoon and level your flour instead of scooping directly from the bag to avoid dry, heavy muffins.
- Cool before storing: Let muffins cool completely on a wire rack to prevent sogginess when stored.
