These bakery-style muffins are sweet, very moist, and easy to make. They will rise and bake to a golden brown. A winning flavor duo that brings together the sweetness of ripe bananas with the burst from juicy blueberries. They are ready in 45 minutes and freeze wonderfully.

Ultimate breakfast muffin?
Though I was expecting a great muffin, this unique flavor combination turned out to be even more delicious. The sweet banana and the juicy blueberries make a great pair.
The batter comes together in no time, so that you can whip it up at a moment's notice. And the blueberries don't sink and are well distributed throughout the batter.
The perfect marriage when you can't decide between banana muffins or blueberry muffins. Lately, I added these oat muffins with banana and blueberries, so now you have another breakfast option.
Testing Notes
Stir the batter by hand. This is not the recipe to use an electric or stand mixer, as it will overmix the batter and make the muffins dense. We don't want that. Use a whisk, two bowls, and then a spatula to fold in the fruit.
Sifting dry ingredients is necessary. It adds air to the batter and dissolves clumps (especially if using baking soda), which helps integrate the ingredients.
A moist crumb is key. Using oil adds richness and not overbaking the muffins ensures soft and moist ones.
Muffins are at their best the day they're baked, and eating them within the first hours makes a difference. That said, I do make and freeze them for hectic mornings or weekends, and these muffins can be revived from a stay in the freezer or from having lost their softness from one day to the other by warming them in a medium oven (350°F/180°C) before eating. Just a few minutes until they're wonderful again.

Ingredient Notes
Quantities are listed on the recipe card towards the end of this post. The Ingredients page has more details and lists the brands we use.
- Blueberries: you can use fresh or frozen berries.
- Bananas: use very ripe ones with brown specks. They have the best, sweetest banana flavor.
- Sugars: white granulated and brown sugar are used. They each bring something to the recipe, but you can use only one of them (1 cup total) if that's all you have.
- Vegetable oil: I use sunflower oil, which is neutral, but coconut oil, canola, or even light olive oil can be used.
- Flour: This recipe works with both all-purpose flour and cake flour.
- Baking powder: make sure it's not expired.
Steps to make blueberry banana muffins
This is an old-fashioned muffin recipe made by mixing the wet ingredients in a bowl and the dry ingredients in another large mixing bowl, and then combining the two. Very easy!

Wet ingredients
Whisk them together in a medium bowl. Use a whisk; there's no need to beat. Then add the mashed bananas. I like them a little chunkier, but you can mash them until very smooth.

Dry ingredients
Sift the flour mixture to avoid impurities and clumps.
Add the liquid ingredients into the dry ones all at once. Fold the fruit gently with a spatula so you don't smash the berries.

Filling the pan
Make sure you distribute the fruit throughout the batter. I like to use an ice cream scoop to fill the paper cups evenly, not exceeding ¾ of their capacity.
Baking
- Muffin tin: I like to use paper liners (paper cups or muffin liners) because it's easier to clean afterward, they keep the muffins moist, and are great if you want to transport them. But you can simply butter or use baking spray for the muffin pan.
- For a crunchier topping, you can add a sprinkling of sugar (half a teaspoon) to each muffin top before baking.
- When are the muffins done? Use the baking time given in the recipe as your guide, check five minutes earlier, and see if the tester or toothpick comes out clean. All ovens are different, so it might take a few minutes more or less than specified.

Storage
Cool completely before storing to prevent sogginess. Use airtight containers, resealable bags, or plastic wrap. Layer muffins with parchment paper to prevent sticking. Remove excess air and seal tightly. Store in a cool, dry place like a pantry.
Avoid refrigerating as it dries out muffins. For freezing (up to one month), wrap well or use airtight containers. Freeze while warm for softer texture. Defrost unwrapped at room temperature and warm slightly in oven before serving.

Banana Blueberry Muffins (easy recipe)
Ingredients
- 1 cup all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- ¼ cup white granulated sugar
- ¼ cup light brown sugar
- 1 egg, at room temperature
- ⅓ cup vegetable oil, like sunflower oil
- ⅔ cup mashed bananas, about 2 medium
- 1 teaspoon vanilla extract
- ¾ cup fresh or frozen blueberries, straight from the freezer; no need to thaw them.
Instructions
- Preheat the oven to 350ºF (180°C).
- Line 12 regular muffin tins with paper liners or butter/spray the pans.
- In a large bowl sift together the dry ingredients: 1 cup all-purpose flour, 1 teaspoon baking powder, ½ teaspoon baking soda, ½ teaspoon salt, ¼ cup white granulated sugar and ¼ cup light brown sugar. Stir to combine.
- Whisk 1 egg, ⅓ cup vegetable oil, and 1 teaspoon vanilla extract in a medium bowl. Do not beat, but mix well until no streaks of egg whites remain.
- Add ⅔ cup mashed bananas and stir.
- Pour the wet ingredients at once to the bowl with the dry ingredients.
- Mix until you barely have streaks of flour, but do NOT overmix. It will be lumpy and not completely mixed and that is fine.
- Add ¾ cup fresh or frozen blueberries and stir lightly to combine with a rubber spatula.
- Divide evenly among the muffin cups or muffin liners.
- Bake for 25-30 minutes, until the top is dry and golden brown, and a cake tester or toothpick inserted in the center comes out clean. Don't overbake.
- Let cool on a wire rack and eat warm or let cool down completely.
- They are best eaten the day they are made, but you can keep them for a day at room temperature covered or wrapped.
- Store leftovers, covered in plastic wrap or in an airtight container, in the refrigerator for a few days or frozen for a month.
