Love this banana bread, you'll also love this classic moist banana bread.

Table of Contents

Ingredients needed:

Butter: Using butter will give our bread the fats it needs to be nice and rich. You could use oil in its place, but the results won’t be as good.
Sugar: We want to use some granulated sugar to make our loaf nice and sweet.
Eggs: This is the binder in the recipe and helps to hold every slice together.
Vanilla: An easy flavor enhancer that gives us a great base for our flavors to work off of.
Sour cream: Using sour cream or Plain Greek Yogurt we can get that moist loaf we’re looking for. Do not use regulate yogurts as they have far too high of moisture content and will not work in this recipe.
Bananas: We want our bananas to be nice and ripe. The riper, the sweeter the bananas are, and the easier they are to mash.
Flour: All-purpose flour is the base of our bread batter.
Baking soda: We need to use baking soda as our leavening agent to help the bread rise while baking.
Salt: This is a natural flavor enhancer that helps to bring out all of the other flavors in this recipe.
Blueberries: We want to use fresh blueberries that have been diced so that they can be scattered throughout the dough without being too large.

How to make blueberry banana bread

Preheat your oven to 350 degrees F.
In a mixing bowl, cream together the butter and sugar for 1-2 minutes.
Add in the eggs and then cream them together again for another 1-2 minutes or until light and fluffy.
Add in the vanilla extract and sour cream. Mix again.
Add in the bananas (whole) and mix until the bananas are broken into smaller pieces and combined into the batter. This should take about 30 seconds.
Add in your dry ingredients and mix again until almost combined but a few flour streaks remain.
Fold in the blueberries until evenly distributed.
Pour your batter into a greased bread pan and bake for 45-50 minutes or until a toothpick comes out almost clean (just a few crumbs on it).

What size bread pan should I use?

I use a 9inx5in the bread pan for this recipe and it turns out wonderfully but you can use a smaller sized pan if desired. If using mini loaf pans you’ll need 2 of them and you will also have to lower the cooking temp by 15 minutes.

If you are using an 8x4 bread pan you may need to extend the baking time, just do it in 5-minute intervals after the allotted time is over and continue to check with a toothpick until done.
