Regular rolled oats: You’ll need 2 cups plus an extra 1/4 cup for topping. Old-fashioned oats work perfectly here and give the muffins amazing texture.
Whole-wheat flour: 3/4 cup adds fiber and makes these muffins extra hearty and satisfying.
Sugar: Just 1/3 cup keeps these muffins naturally sweet. You can use a sugar substitute if you prefer!
Baking powder: 1 teaspoon helps these muffins rise up nice and fluffy.
Apple pie spice or ground cinnamon: 3/4 teaspoon plus an extra 1/2 teaspoon for topping adds that warm, cozy flavor we all love.
Baking soda: 1/2 teaspoon works with the buttermilk to make everything light and tender.
Salt: Just 1/4 teaspoon brings out all the flavors beautifully.
Buttermilk: 1 cup makes these muffins incredibly moist and adds a subtle tangy flavor.
Eggs: 1/2 cup egg product or 2 large eggs beaten up bind everything together perfectly.
Ripe banana: 1 large banana mashed up is the star of the show! The riper, the better for maximum sweetness.
Butter: 2 tablespoons melted plus 1 tablespoon for the topping adds richness without going overboard.
Vanilla: 1 teaspoon makes everything smell and taste amazing.
How to Make Banana-Oat Muffins

Step 1: Preheat your oven to 350 degrees F. Line twelve muffin cups with paper liners and spray lightly with cooking spray. Put 2 cups of oats in your food processor or blender. Blend until they’re finely ground like flour. Transfer the ground oats to a large bowl.
Step 2: Stir the whole-wheat flour, sugar, baking powder, 3/4 teaspoon apple pie spice, baking soda, and salt into the ground oats. Make a little well in the center and set aside.
Step 3: In a medium bowl, whisk together the buttermilk and eggs. Add the mashed banana, 2 tablespoons melted butter, and vanilla. Whisk everything together until smooth.
Step 4: Pour the wet ingredients into the flour mixture all at once. Stir just until everything is moistened – the batter should look lumpy! Don’t overmix or your muffins will be tough.
Step 5: Spoon the batter into your prepared muffin cups, filling each about three-fourths full. This gives them room to rise perfectly.
Step 6: For the topping, mix 1/4 cup oats with 1/2 teaspoon apple pie spice in a small bowl. Cut in 1 tablespoon butter with a pastry blender until it looks like coarse crumbs. Sprinkle this mixture on top of each muffin.
Step 7: Bake for 20 to 22 minutes until a toothpick inserted in the center comes out clean. Cool in the pan for 5 minutes, then remove and serve warm.
Easy and Quick Banana-Oat Muffins Version
Want to save some time? You can skip making the crumb topping and just sprinkle a little cinnamon and sugar on top instead! Also, if you have oat flour already, use 1 1/2 cups oat flour instead of grinding your own oats. This cuts your prep time down to just 15 minutes!
Serving Ideas
These muffins make a complete breakfast or snack all by themselves! They’re perfect with a glass of cold milk or your morning coffee. You can also serve them alongside fresh berries or a dollop of Greek yogurt for extra protein.
Storage
Store your muffins in an airtight container at room temperature for up to 2 days. For longer storage, freeze them for up to 1 month. To reheat, just pop them in the microwave for 15-20 seconds or warm them in a 300°F oven for 5 minutes.
Substitutions
No buttermilk? Mix 1 cup regular milk with 1 tablespoon lemon juice and let it sit for 5 minutes! You can swap the whole-wheat flour for all-purpose flour if that’s what you have. Regular milk works fine too, though the muffins won’t be quite as tangy.
Pro Tips
- Perfect Banana Ripeness: Use bananas that have brown spots – they’re sweeter and mash easier!
- Don’t Overmix: Lumpy batter is your friend. Overmixing makes tough muffins.
- Even Filling: Use an ice cream scoop to fill muffin cups evenly every time.
- Test for Doneness: The toothpick should come out with just a few moist crumbs, not wet batter.
FAQs
Can I make these muffins without a food processor?
Sure! You can buy oat flour from the store, or put your oats in a blender. Even a coffee grinder works for small batches. Just pulse until the oats look like flour!
Can I use frozen bananas?
You bet! Just thaw them completely and drain any extra liquid before mashing. Frozen bananas actually work great because they get super soft and sweet.
How do I know when the muffins are done?
The tops should spring back when you lightly touch them, and a toothpick inserted in the center should come out clean or with just a few moist crumbs. They’ll also start to pull away slightly from the sides of the muffin cups.
Can I double this recipe?
Absolutely! This recipe doubles perfectly. You’ll just need two 12-cup muffin pans or bake them in batches. The baking time stays the same.
I hope you love these banana-oat muffins as much as my family does! They’ve become our go-to healthy treat. Let me know how yours turn out – I’d love to hear about any fun variations you try!
