Looking for a great way to use up overripe bananas? Make these blueberry banana oat muffins. They were created as a way to use up leftover overripe bananas from banana oat pancakes and a pint of fresh blueberries that needed to be eaten. I wanted to make healthy muffins that could double as a quick and easy breakfast for busy mornings but didn't taste too healthy.
Ingredients
You'll only need a handful of simple ingredients to make these fluffy muffins:
- Oat flour - (made from pulverized old-fashioned oats) gives the muffins a really nice texture. the muffins w.
- Baking soda and baking powder.
- Kosher salt - a pinch to balance out the sweetness.
- Ripe, spotty bananas - they add both natural sweetness and moisture. For the best results, use bananas that aren't completely black as it could add too much moisture to the muffins.
- Melted coconut oil - I suggest using refined coconut oil for no coconut taste.
- Maple syrup - brings out the natural sweetness in the bananas and flavor to the muffins.
- Vanilla extract - another layer of flavor.
- Large eggs - acts as the binder and helps hold the muffins together.
- Juicy blueberries - I prefer fresh fruit for the best blueberry flavor, but you can also use frozen if it's what you have on hand.

Step 1. Preheat your oven to 375ºF. Grease a 12-cup muffin pan with cooking spray or oil.

Frequently Asked Questions
Flax eggs don't work very well with oat flour and can lead to a gummy or dense texture. I only recommend using flax eggs if you're going to use all purpose flour in place of the oat flour as the gluten allows more flexibility.
There's no need to use muffin liners if you grease the muffin wells of your muffin pan first.

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.
