You know what’s better than a bakery muffin? Homemade! Yep, these from-scratch, homemade banana blueberry muffins are so much better than the local bakery. They are light and fluffy, yet moist and tender.

The muffins tops bake up nice and tall. Best of all, there is a thick, crunchy-super-yummy-cinnamon-crumb-topping. It is addictive. So grab a cup of coffee and sit down to these homemade banana blueberry muffins.

The Ingredients

Here is a list of the ingredients you will need for the best banana blueberry muffins. Most of the items on the list are pantry ingredients that last for a long time. If you purchase them in bulk, you can make so many things on a whim like our banana layer cake, our fig cake (when figs are in season), or our Starbucks banana bread.

For the dry ingredients

  • Flour. All-purpose flour works fine in this recipe. If you want to use cake flour for a slightly lighter muffin then feel free to substitute with cake flour. You will need the flour for the muffin as well as the streusel topping.
  • Baking powder and baking soda. This recipe uses two leaveners to help lighten and aerate the muffins. Make sure they are not expired or your banana blueberry muffins will fall flat.
  • Cinnamon. Use the cinnamon in both the muffin batter and the streusel topping.
  • Salt. Salt enhances the flavors. Even though it doesn’t take much, don’t skip this ingredient.

The wet ingredients

  • Butter. Use the butter in the muffin batter and in the streusel topping. You can use salted or unsalted butter (I prefer salted butter).
  • Brown sugar. Sugar isn’t exactly “wet” but it is important to treat it as a wet ingredient for this recipe. Adding it with the wet ingredients will help reduce gluten formation and keep the banana blueberry muffins tender.
  • Eggs. Eggs are important for the structure and tender texture of these muffins.
  • Vanilla extract. It’s amazing that just a small dash of vanilla can enhance all the sweet flavors in these muffins.
  • Bananas. Make sure the bananas are very ripe.

Of course, you will need blueberries or we couldn’t call this recipe banana blueberry muffins. You can use fresh or frozen blueberries. Make sure you read the tips if you plan to use frozen blueberries.

By the way, if all you need is a quick, personal-sized treat with bananas and blueberries, you can add some blueberries to this banana mug cake. It makes a great midnight snack.

Tips for the Best Blueberry Banana Muffins

Homemade muffins are easy to make but if you want perfect results, we have a few tips.

Measure the mashed bananas.

Bananas come in all shapes and sizes. The recipe calls for 1-1/2 cups of bananas, which is typically 3 to 4 bananas. It might only be two bananas if they are really large.

If you’re tempted to add more banana mash thinking it will add more moisture and banana flavor, you could end up with a flat, dense muffin. 

Mix the wet and dry ingredients separately.

Mix the dry ingredients in one bowl then mix the wet ingredients in another bowl. Finally, add the wet ingredients to the dry ingredients and fold them together gently. This technique will help prevent you from over-mixing the ingredients

Don’t over-mix the batter.

You want the batter to be light and even slightly under-mixed before adding the blueberries. Once you add the blueberries, fold them in just until they are blended.

Stirring the batter too much will develop the gluten in the flour and make the crumb tough. It will also cause the blueberries to burst and make the entire batter purple.

Fill the muffin tins to the top.

If you want the muffins to have really tall muffin tops, then fill the tins all the way to the top. The batter is nice and thick so it won’t run out if you fill the tins to the brim.

For tall muffin tops, start with a hot oven.

To get the most rise and tallest muffin tops, bake the muffins at 425°F for the first five minutes then turn the oven down to 350°F for the rest of the time.

When you start baking the muffins at a higher temperature it will give the muffins an extra burst of heat. The immediate burst of heat will cause the baking powder to react quicker and start rising higher. Don’t open the oven when you turn it down after 5 minutes and don’t walk away and forget to turn the oven down to 350°.

You want to finish the baking time at 350°F. If you bake the muffins at 425°F the whole time you will end up with over-baked, dry muffins. So, if you think you’re likely to forget about turning the oven down, then just set the oven at 350° for the entire bake time.

Can you use frozen blueberries to make muffins?

You can use frozen blueberries for this muffin recipe but make sure they are still frozen when you add them to the batter.

If you thaw the blueberries before adding them to the batter, then the blueberries will burst open when you fold them into the batter. Also, the juices from the berries will mix into the batter and you will have purple muffins.

So if you are using frozen blueberries, keep them in the freezer until it is time to add them to the batter.

Since frozen blueberries will release more liquid than fresh blueberries, the berries will tend to sink to the bottom of the muffin. You can remedy that problem if you toss the berries in a couple of tablespoons of flour before adding them to the batter.

The final thing to keep in mind if you use frozen blueberries is the cooking time. You will need to add a couple of minutes to the total baking time if you start with frozen berries. Depending on your oven, it shouldn’t take more than two minutes longer. Just stick a toothpick in the center of the muffin to see if it is done.

Banana Blueberry Muffins with Crumb Topping

Yield: 12
Prep Time: 5 minutes
Cook Time: 17 minutes
Total Time: 22 minutes

These bakery-style banana blueberry muffins have a crunchy cinnamon crumb topping and they are loaded with juicy blueberries.

Ingredients

Dry ingredients:

  • 2-1/4 cups all-purpose flour (270 grams)
  • 1 tablespoon baking powder
  • 3/4 teaspoon baking soda
  • 1/2 teaspoon cinnamon
  • 1/2 teaspoon salt

Wet Ingredients:

  • 1/2 cup butter, melted
  • 3/4 cup packed brown sugar (156 grams)
  • 2 eggs
  • 2 teaspoons vanilla extract
  • 1-1/2 cups mashed bananas (about 3 to 4 bananas)

Add In:

  • 2 cups fresh or frozen blueberries

Cinnamon Crumb Topping

  • 3/4 cup all-purpose flour (90 grams)
  • 1/2 cup granulated sugar (100 grams)
  • 1 teaspoon cinnamon
  • 4 tablespoons butter, melted

Instructions

  1. Preheat the oven to 425°F (you will reduce the temperature after the muffins cook for 5 minutes)
  2. 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.
  3. 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.
  4. Fold the wet mixture into the flour mixture then fold in the blueberries.

Make the cinnamon crumb topping:

  1. Blend the flour, sugar, and cinnamon together then stir in the melted butter until you have pea-sized clumps.
  2. Fill the greased muffin tins completely full then sprinkle the tops with the cinnamon crumb topping.
  3. Bake in the preheated oven at 425°F for 5 minutes then turn the oven down to 350°F and bake for 12 to15 more minutes or until a toothpick inserted in the center comes out clean.
  4. Allow the muffins to cool completely before removing from the muffin tins. The tender muffins can fall apart if you remove them while they are still warm.

Notes

If you are using frozen blueberries, do not thaw them before adding them to the batter. Toss frozen blueberries in a couple of tablespoons of flour first. This will prevent the blueberries from falling to the bottom of the muffin.

For a dairy-free recipe, substitute the butter for coconut oil or vegetable oil.
