These healthy banana oatmeal blueberry muffins are super moist and soft, not overly sweet and full of juicy blueberry and banana flavor. The crisp oat and cinnamon crumble topping can be optional (if you want them for breakfast, skip it) or enjoy the blueberry banana oatmeal muffins as a treat, it gives them extra texture and sweetness.
Mash the bananas with a fork. You will get approximately 1 cup from 2 large or 3 smaller bananas. Add to a bowl together with the eggs, melted butter, vanilla extract and apple cider vinegar. Mix to combine.
Step 2. Soak the rolled oats:
To the same bowl, add the oats (1 cup) and fold together until well incorporated. Let them soak for 7-10 min to expand and absorb as much as possible the moisture. Meanwhile prepare the rest of ingredients.
Step 3. Mix in the dry ingredients:
To that add the dry ingredients (maple sugar, flour, salt and baking powder). Reserve 1-2 tablespoons of flour to coat the blueberries.
Then add the blueberries (coated with flour), gently incorporate them into the muffin batter.
Spoon the batter into the prepared muffin tins, filling each about three-fourths full.
Step 4. Make the crumble topping (optional):
Add all ingredients in a small bowl. Mix with your hand to combine. Sprinkle the topping evenly on top of the unbaked muffins.
Step 5. Bake the banana blueberry oat muffin:
Bake the muffins at 400F for 10 minutes then reduce the temperature to 375F and bake for another 20-25 minutes. If you’re using gluten free flour you might need additional 5-10 minutes.
Cool the muffins in the pan on a rack for 5 minutes, then remove to a wire rack to cool completely. Once cooled the texture improves and stiffens, and the insides aren’t wet anymore.
Notes
Dairy Free & Gluten Free Option
Use coconut milk as a substitute for the regular milk but there are many other dairy free, milk alternatives like almond, cashew, hemp or oat milk – they all work.
Instead of regular butter, I use a plant based butter, but you can easily use some unflavored oil, like avocado oil or grape-seed oil.
For gluten free version use a gluten free flour mix. Using a single type of gluten free flour like rice or sorghum might yield a really crumbly texture and probably dry.
Tips For Perfect Oatmeal Banana Blueberry Muffins
The thicker the muffin batter, the taller and puffier the blueberry banana oatmeal muffin will be.
Over-mixing the batter can cause tough muffins.
Fresh blueberries or frozen both work. Be warned that if you choose frozen, the muffin batter may get a little of a blueberry-purple color.
