These Banana Oatmeal Muffins are made with wholesome ingredients like oat flour (easy to make at home), ripe bananas, coconut oil and Greek yogurt. They come out moist, tender and nutrient-rich—an excellent option for breakfast, snack or meal prep.

Bananas and oats are a classic pairing—I often use them in pancakes and overnight oats. These muffins are another way to enjoy that comforting combination. They travel well, freeze nicely, and make an easy grab-and-go breakfast. They’re toddler-approved in my house, which earns them extra points!
Why we love oat flour muffins
- Nutrient dense: Each muffin provides protein and fiber from oats and Greek yogurt.
- Super fluffy: These healthy muffins stay light and tender rather than dense.
- Gluten-free option: Use certified gluten-free oats to make this recipe gluten-free.
How to Make Oat Flour
Making oat flour at home is quick and useful when you don’t keep many different flours on hand:
- Place old-fashioned (rolled) oats or quick oats in a high-speed blender or food processor.
- Blend until the texture is fine and powdery.
Note: Avoid steel-cut oats for this purpose—they are too dense to blend into a fine flour. If you prefer, store-bought oat flour works perfectly as well.

Delicious Topping Ideas
For the photos, each muffin was topped with a thin slice of banana and a sprinkle of oats before baking—simple and attractive. Another favorite is a streusel topping for extra texture and sweetness.
Streusel topping:
- ½ cup oat flour
- 1.5 tablespoons brown sugar
- 1.5 tablespoons coconut oil
To make the streusel, combine the oat flour, brown sugar and coconut oil with your fingers or a fork until the mixture resembles wet sand. Sprinkle evenly over the muffin batter before baking.

Storage and Shelf Life
Store these muffins in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to 1 week.
Freezing: Place muffins in a freezer bag and freeze for up to 3 months. Thaw at room temperature or warm briefly in the microwave or oven.
