These banana blueberry oatmeal muffins are simple, wholesome, and absolutely delicious. An added bonus is that they're naturally sweetened and incredibly easy to make. This recipe is gluten-free, dairy-free, nut-free, and vegetarian.

I had leftover bananas from my banana oat pancakes that needed to be used up and a pint of fresh blueberries in the fridge. I wanted a fluffy, moist muffin that was healthy enough to enjoy for breakfast or a snack yet still tasted indulgent.
And these muffins have all of those qualities. Unlike many sugar-laden muffins, these are lightly sweetened and fiber-rich. There's no milk or butter, just a few pantry staples you likely already have on hand.
Ingredients
- Oat flour - which is just pulverized old-fashioned oats.
- Baking soda and baking powder.
- Kosher salt.
- Ripe, spotty bananas - not only do ripe bananas add more moisture to the muffins, but they act as a natural sweetener as well.
- Melted coconut oil - I like refined for no coconut taste.
- Maple syrup.
- Vanilla extract.
- Large eggs.
- Blueberries - fresh or frozen (and defrosted).
How to Make Banana Blueberry Oatmeal Muffins
Step 1. Preheat your oven to 375ºF. Grease a muffin tin with oil.
Step 2. In a medium-sized mixing bowl, whisk together the oat flour, baking soda, baking powder, and salt. Set aside.
Step 3. In a large mixing bowl, mash the spotty bananas with a fork, then add in the melted coconut oil, maple syrup, vanilla extract, and eggs. Whisk to combine.
Step 4. Pour the dry ingredients into the wet and fold until just combined, being careful not to over-mix. Fold in the blueberries. Divide the batter evenly between the greased muffin wells.
Step 5. Bake for 18-20 minutes. Let cool for a few minutes before transferring the muffins to a wire rack.
Make It Your Way: Substitutions & Variations
Please remember that recipes are just a starting point.
How can you make these banana blueberry oatmeal muffins using what you already have? Here are some ideas…
- No oat flour? - make your own by blending old-fashioned rolled oats in a blender. Use certified gluten-free oats if necessary.
- No coconut oil? - olive oil, avocado oil, or melted dairy-free (or regular) butter are great alternatives.
- No maple syrup? - use raw honey instead.
- No vanilla extract? - you could also use almond extract, ground cinnamon, ground cardamom, or lemon zest. Really anything to give them another dimension of flavor.
- Variations - use another type of berry such as blackberries, or raspberries. Just be aware that these have seeds. Or you could also use chopped fruit such as pear, apple, nectarine, persimmon, etc.
How to Store
Store the muffins at room temperature in an airtight container for up to 5 days or in the freezer for up to 3 months.

Evie Ugrin says
The Banana Oatmeal Muffins are great for breakfast and for snacking.
Not having enough ripe bananas, an added 1/2 cup grated apple worked well.
Before baking, a lot got sprinkling of cinnamon and maple sugar gave a crispy top.
