How To Make Banana Blueberry Muffins
Since my To Die For Blueberry Muffins and my Banana bread recipe is always a hit with my family. I decided that I would create a new muffin recipe by combining the flavors of these two recipes.
Not sure if it's the fact these moist banana muffins are loaded with blueberries or the streusel topping that makes these such a hit. But every time I make these homemade muffins for my family they don't last long.
The crumb topping sure brings in a buttery flavor, the blueberries complement the banana flavor. The mashed bananas make the muffins moist, which makes these muffins amazing.

Let's talk about the bananas first for this recipe. I feel that overripe bananas work best. Overripe bananas have a stronger flavor and are easier to mash up.
So if you have some overripe bananas laying around this is a great recipe to use them up in. There were four in the batch of bananas that I had that was ready to be used, the extra banana brings more flavor.
Be careful not to use too many bananas when using them in bread or muffins. Too many bananas can make the bread of muffins heavy and damp in the center.

In a large bowl combine the mashed bananas, oil, sugar, milk, eggs, and vanilla extract. Mix all these wet ingredients together using an electric mixer like a handheld mixer or a stand mixer.
I firmly believe in sifting my flour whenever I bake. In our article a Baker's Dozen we talk about why to sift flour as well as how to measure flour.
Into the wet ingredients add the sifted flour, baking soda, baking powder, and salt. Mix these ingredients together until the dry ingredients are combined with the banana mixture.

Fresh Or Frozen Blueberries
In these banana blueberry muffins I have used both frozen and fresh, honestly, I prefer fresh blueberries. The frozen didn't seem to bring as much flavor to the recipe as the fresh did. When I did use the frozen, the batter was a little discolored from the blueberries.
A pro tip would be to roll the fresh blueberries in flour before adding them to the batter. This will help to evenly distribute the blueberries into the muffins.

To make these muffins even better I added walnuts into the batter with the juciey blueberries. Once you have decided fresh or frozen for the blueberries gently fold them into the batter.
I'm all about easy cleaning up so I always use cupcake paper liners whenever I make muffins. To help the muffins from sticking to the liners you could lightly spray the liners with cooking spray.
If you choose not to use liners then I definitely would spray the muffin pan with baking spray. Silicone muffin pans could also be useful in baking these muffins. I have never used a silicone muffin pan so the baking time may need to be adjusted.
Using a 2-inch cookie scoop to scoop the batter into the cupcake liners. This filled the liners up about ¾ of the way full which you will want to make sure not to overfill or you won't have room for the crumb topping.
Crumb Topping

To crumb or not to crumb is totally up to you. But I really feel the streusel topping makes these banana blueberry muffins even better.
In a mixing bowl melt the butter, then add the sifted flour, sugar, and ground cinnamon. As you mix the ingredients will start to form clumps and stay together.
Sprinkle the crumb topping onto the top of each muffin that is in the baking tin. I was able to sprinkle about 1 tablespoon on top of the muffin batter.

Okay, so here I'm going to share with you a baking tip I didn't do this time but normally do. Place the muffin tin on another baking sheet.
Like I said I didn't this time and the streusel topping fell onto the bottom of my oven. Causing a smelly mess on the bottom of my oven.
These will bake in a 350℉ oven for 20-25 minutes, or until the crumb topping is golden brown. And the muffin feels firm when pressed in the center.

To make these homemade banana blueberry muffins even better make them larger, add more blueberries and a bit of lemon zest.
These homemade banana blueberry crumb muffins have the perfect texture just like a bakery muffin. Making them the perfect breakfast treat.
