Tips on making this blueberry banana bread recipe

You want to make sure you use very ripe bananas. Bananas that have lots of black specks. The blacker the banana is the sweeter it will be. I actually like to freeze my bananas when they have gotten too ripe to use later for banana bread. If you use frozen bananas, then let the bananas thaw before using them.
Mash your bananas before adding them to the mixing bowl. I do this by hand with a fork since I have used frozen bananas they are very easily mashed. You could also use a pastry blender, potato masher, or a hand mixer.
When you add the oil into your the sugar and eggs you want to S-L-O-W-L-Y add the oil in with your mixer on low. This step should take about a minute. So slow. If you add the oil in all at once you risk of deflating all that air you incorporated into the eggs and sugar in the step before.
Measure your flour accurately. I use the spoon and level method. You can learn how to measure your flour in this post.
Careful to not over mix. I like to use a spatula and fold in the dry ingredients by hand. You want to stop mixing once they have been incorporated. Too much mixing = too much gluten forming. Gluten is what will give a bread its chew, but for a banana bread you want less gluten to form. So we can accomplish that by making sure we don’t overmix!

How to make this blueberry banana bread recipe – step by step

Step 1: Sift your dry ingredients

Set your sifter over a mixing bowl and then measure and add the flour, baking soda, cinnamon, and salt. And set aside. Sifting is necessary to remove any lumps and aerate the mixture to help create a light fluffy bread.

Step 2: Toss the blueberries with flour

Use a tablespoon of the dry ingredients you just sifted and mix that with your blueberries. You want to toss the blueberries with flour, so it prevents them from sinking in the batter when baking. I do the same thing to keep chocolate chips from sinking.

Step 3: Mash your bananas

Before I start mixing the liquid ingredients, I like to go ahead and mash my bananas so those are ready for me and waiting. I just simply use a fork to mash up the bananas in a bowl. For this recipe, it takes about 3 1/2 bananas.

Step 4: Mix your eggs and sugar

In a stand mixer, or in a bowl with a hand mixer you are going to mix the eggs and sugar together for 5 minutes until pale and fluff. This creates a lot of air into the mixture. The mixture should be pale yellow and ribbony.

Step 5: Add In The Liquid Ingredients

First you want to use a neutral tasting oil. I used vegetable oil but canola oil works as well. You want to stream this in with the mixer running on low. Take your time doing this so you don’t deflate all the air you just whipped into the mixture.

Then add in the bananas, vanilla extract, and sour cream.

Step 6: Fold In The Dry Ingredients

Now using a spatula, fold in the dry ingredients. Just don’t overmix! Overmixing will cause the gluten in the flour to form and too much gluten creates a tough bread. So stop mixing once the last streak of flour is incorporated.

Step 7: Fold in the blueberries

Using a spatula, just gently fold in the blueberries.

Step 8: Place In Pan

Then you want to pour the batter into your greased 9×5 inch loaf pan and bake! Bake on a middle rack in a pre-heated oven. And bake for 60-70 minutes until a toothpick comes out clean.
