Oatmeal banana muffins
These tasty banana muffins have plenty of banana flavor and get a chewy texture from the old-fashioned oats. And to take these muffins a step further, I’ve added a delicious oat topping.
No special equipment needed when making these muffins. You need a bowl, a heavy-duty spoon for mixing, and a muffin tin for baking. Whether you’re a novice in the kitchen or an experienced baker, these banana oatmeal muffins will get you rave reviews in your kitchen!
My top tips for making these muffins include
- Use Very Ripe Bananas: Overripe bananas with dark spots or fully brown skins work best, as they provide natural sweetness and a moist texture.
- Don’t Skip the Oats: Use old-fashioned oats for a chewy texture that complements the banana flavor. Quick oats can alter the texture and may not absorb liquid as well.
- Perfect Crumb Topping: Ensure the crumb topping is mixed until it resembles coarse crumbs. This adds a sweet, crunchy layer to the muffins.
- Even Muffin Sizes: Fill the muffin cups evenly using an ice cream scoop.
For another easy banana muffin, try my mini banana muffins. They’re made in one bowl and bake in just 10–12 minutes. If you're wanting a banana muffin with nuts, try my banana walnut muffins.
Banana Oat Muffin Ingredients
- Oats - Use old-fashioned oats or rolled oats. They have a thicker texture than quick oats and are perfect in this recipe.
- Flour - Regular all-purpose flour is used. Be certain to measure your flour using the fluff and scoop method.
- Bananas - The riper the bananas, the better. Choose very brown bananas. You’ll need 1½ cups of mashed bananas which is about 3 bananas.
- Sugar - Two types of sugar are used in this recipe. Granulated sugar is used in the muffin batter and brown sugar is used for the topping.
- Oil - The oil adds moisture and helps create a perfect crumb. Use a light-flavored oil like canola or vegetable oil.
- Spices - Ground cinnamon and nutmeg add the perfect amount of spice.
- Vanilla - Use pure vanilla for the best flavor.
- Leavening - One egg, baking powder, and baking soda are all used in this recipe.
How to make Banana Oatmeal Muffins
- Mix the oatmeal, flour, baking powder, baking soda, cinnamon, nutmeg, and sugar in a large bowl.
- In a smaller bowl mix egg, oil, and vanilla. Add to dry ingredients and stir.
- Stir in mashed bananas.
- Fold together until well combined.
- Divide into 12 sprayed or lined muffin tins.
- Mix the remaining oats, melted butter, brown sugar, and cinnamon.
- Sprinkle topping over unbaked muffins.
- Bake in a preheated 375°F oven for 15-20 minutes.

How to store Banana Oat Muffins
Once the muffins are fully cool, store them in a single layer in an airtight container. Store at room temperature for 3-4 days.
To freeze the muffins, place fully cool muffins in a freezer-safe container or bag in a single layer. Muffins are best used within 1-2 months.
Tips for making Banana Oatmeal Muffins
- Use fresh baking powder - baking powder can lose its effectiveness and if old, your muffins might not rise properly.
- Fully preheat your oven - I use a separate oven thermometer in my oven to make certain my oven has reached the proper temperature. My preheat light often turns off before the oven has reached full temperature so I always give it extra time.
- Do not overmix batter. Just stir until everything is mixed in. Over-stirring can cause tough muffins.
- Use an ice cream scoop for even-sized muffins. Plus it makes putting the batter in the tins easy peasy!

Notes
