Oatmeal banana muffins
These muffins showcase banana flavor and a pleasant chew from old-fashioned oats. A crunchy oat crumb topping elevates them further.
No special tools are required—just a bowl, a sturdy spoon, and a muffin tin. Whether you’re a beginner or an experienced baker, these banana oat muffins are reliable and crowd-pleasing.
Top tips for best results:
- Use very ripe bananas: Bananas with brown spots or fully brown skins give the best natural sweetness and moisture.
- Choose old-fashioned oats: Rolled oats provide the chewy texture that complements the banana. Quick oats change the texture and may not absorb liquid the same way.
- Make a proper crumb topping: Mix the topping until it forms coarse crumbs for a sweet, crunchy finish.
- Portion evenly: Use an ice cream scoop to fill muffin cups for consistent results.
Banana Oat Muffin Ingredients

- Oats – Old-fashioned or rolled oats for texture.
- Flour – All-purpose flour measured properly for consistent results.
- Bananas – Very ripe bananas; you’ll need about 1½ cups mashed (roughly 3 bananas).
- Sugar – Granulated sugar in the batter and brown sugar for the topping.
- Oil – A light-flavored oil (canola or vegetable) keeps the muffins moist.
- Spices – Ground cinnamon and a pinch of nutmeg add warmth.
- Vanilla – Use pure vanilla for the best flavor.
- Leavening – One egg plus baking powder and baking soda help the muffins rise.
How to make Banana Oatmeal Muffins

- Combine the oats, flour, baking powder, baking soda, cinnamon, nutmeg, salt, and sugar in a large bowl.

- Whisk the egg, oil, and vanilla in a smaller bowl, then add to the dry ingredients and stir. The mixture will be dry at this point.

- Fold in the mashed bananas, mixing until just combined.

- Gently fold until the batter is evenly combined—avoid overmixing to keep the muffins tender.

- Divide the batter evenly among 12 lightly sprayed or lined muffin cups.

- Combine the topping ingredients—oats, melted butter, brown sugar, and cinnamon—until coarse crumbs form.

- Sprinkle the oat topping over the unbaked muffins.

- Bake in a preheated 375°F (190°C) oven for about 18–20 minutes, until a toothpick inserted in the center comes out clean.
How to store Banana Oat Muffins
When cool, store muffins in a single layer in an airtight container at room temperature for 3–4 days.
To freeze, cool completely and place in a freezer-safe bag or container in a single layer. Freeze up to 1–2 months for best quality.
Tips for making Banana Oatmeal Muffins
- Use fresh baking powder so your muffins rise properly.
- Fully preheat your oven; an oven thermometer helps ensure correct temperature.
- Do not overmix the batter—stir only until ingredients are combined to avoid tough muffins.
- An ice cream scoop yields even muffin sizes and makes filling the cups easier.

- Oats add pleasing texture to the muffins.
