Banana blueberry muffins are tender, loaded with bananas, and bursting with juicy berries. A cinnamon crumb topping bakes into a golden, crunchy crown that takes them past ordinary muffins. Think of them as a mash-up between classic banana bread and my blueberry streusel muffins. The result? Tall muffins with soft centers, jammy blueberry pockets, and crisp, spiced tops.

Here’s Why This Banana Blueberry Muffin Recipe Works
Double the flavor: Ripe bananas add depth and sweetness, while blueberries keep each bite bright and juicy.
Bakery-style tops: Starting the oven hot gives the muffins a big rise, then lowering the temperature keeps them tender inside.
Built-in crunch: The cinnamon-sugar topping adds a sweet, crackly layer over the tender muffin base.
Flexible batch size: Fill tins to the brim for 12 oversized muffins or fill slightly less for 18 smaller muffins.
Recipe Tips
Measure bananas after mashing: Bananas vary in size; 1 ½ cups is the sweet spot for balanced moisture.
Don’t overmix: Stir the wet and dry just until combined, too much mixing toughens the crumb.
Keep frozen blueberries frozen: If using frozen, fold them in straight from the freezer to avoid blue-streaked batter.
Pile on the topping: The crumb mix should look like chunky sand before baking, it crisps beautifully in the oven.
Cool before removing: Muffins are fragile when hot; wait at least 10 minutes before lifting them out.

Banana Blueberry Muffins with Crumb Topping

Ingredients
Dry ingredients:
- 2 ¼ cups all-purpose flour, (270 grams)
- 1 tablespoon baking powder
- ¾ teaspoon baking soda
- ½ teaspoon ground cinnamon
- ½ teaspoon salt
Wet Ingredients:
- ½ cup butter, melted
- ¾ cup brown sugar, (156 grams)
- 2 large eggs
- 2 teaspoons vanilla extract
- 3 to 4 bananas, 1-½ cups mashed
Add In:
- 2 cups fresh or frozen blueberries
Cinnamon Crumb Topping
- ¾ cup all-purpose flour, (90 grams)
- ½ cup granulated sugar, (100 grams)
- 1 teaspoon ground cinnamon
- 4 tablespoons butter, melted
Instructions
- Before you begin, you will get the best results if you mash the bananas first then measure out the exact amount needed.
- Preheat the oven to 425°F (you will reduce the temperature after the muffins cook for 5 minutes)
- Grease 12 standard-sized muffin tins or line them with paper baking cups. In a medium bowl, whisk all the dry ingredients together then set aside.
- In another bowl, beat the butter and brown sugar then add the eggs and beat until well blended.
- Next add the vanilla, and mashed bananas and beat until well combined.
- Fold the flour mixture into the wet mixture then fold in the blueberries.
Make the cinnamon crumb topping:
- Blend the flour, sugar, and cinnamon together then stir in the melted butter until you have pea-sized clumps.
- Fill the greased muffin tins completely full with the batter then sprinkle the tops with the cinnamon crumb topping. For slightly smaller muffins, you can fill the tins ¾ full which will give you 18 muffins (but you will need to reduce the baking time by a couple minutes).This recipe makes a generous amount of crumb topping. Don’t be shy about loading it onto the muffins. If you prefer a lighter topping, you may have some leftover.
- Bake in the preheated oven at 425°F for 5 minutes then turn the oven down to 350°F and bake for 12 to 16 more minutes or until a toothpick inserted in the center comes out clean.
- Allow the muffins to cool for at least 10 minutes before removing from the muffin tins. The tender muffins can fall apart if you remove them while they are still warm.

I just made them, following recipe as is with no changes. Wow, are they good! After letting the cool down for 15 minutes after removing from the oven, I ate three, lol!
They are moist and bursting with flavor. The only thing I didn’t care for was that I had a lot of crumb topping remaining after topping the muffins. That seems wasteful to me. I saved this recipe on my phone and will be making again. Thanks for sharing!
I’m so glad you enjoyed the muffins. The recipe does make a generous amount of crumb topping, since some people like to really load it on or make 18 smaller muffins instead of 12. If you prefer a lighter topping, you can sprinkle less and just save the extra for another batch. Thanks so much for taking the time to leave a review
I made these and my family loved them so much will be a regular recipe in my house. Thank you! So yummy. I even made cake flour they were so soft.
That makes me so happy to hear! Thanks for the comment.
I would like to split half the batter and substitute Chocolate chips for the blueberries. Should I add more liquid to that batter with the choc chips?
That swap will work great! You don’t need to add extra liquid—just replace the blueberries with the same amount of chocolate chips. The batter’s moisture level will still be right where it needs to be.
Great recipe – very delicious muffins!
I substituted 1/2 cup quinoa flour (doing for all my baking to add fiber and make little bit healthier). Also – somehow I was able to bake the 1x batch into a 20 muffins. Family is not complaining LOL
Thanks a lot!
Looking forward to trying other your baking recipes as well!
Thank you so much! I’m glad you enjoyed them. Quinoa flour is such a creative swap. Thanks for the comment.
Great recipe, very moist but not sweet enough for me so I drizzled with a royal icing which looked cool and added more crunch.
Thanks for the comment, I bet the icing was delicious.
I made a double batch for our family and and took one batch to our church. All of us agree that your recipe is phenomenally delicious! The crunchy sweet topping really hits the spot. This is definitely a keeper🙌
So glad to hear that, thanks for sharing! I’m thrilled they were a hit with both your family and church group. That crunchy topping gets me every time!
I haven’t made these yet ! Trying to make plans for my two very ripe bananas … I was hoping a comment mentioned what to tweak on the recipe if I don’t have 3 or 4, help please ! This recipe sounds too good not to try0:)
