Banana Bread Ingredients

  • Granulated sugar: depending on the ripeness of the bananas, the sugar amount can be reduced just a bit, if desired.
  • Oil: use a neutral-flavored baking oil, like canola, vegetable, grapeseed, etc.
  • Eggs: necessary leavening and assists in producing a fluffy crumb.
  • Bananas: use bananas that are speckled and ultra-ripe for the best flavor.
  • Sour cream: the acidity in the sour cream is necessary for the baking soda to do its job, and it also contributes to the banana bread’s moist texture.

A few other baking ingredients are also used for flavor and leavening: vanilla extract, baking soda and salt.

What Causes the Speckles in Banana Bread?

Have you ever wondered why some loaves of banana bread have dark speckles and others don’t?

The reason: Baking soda!

➡️➡️ Banana bread recipes that have more baking soda and less baking powder usually have a darker, more speckled crumb. This sour cream banana bread has a full teaspoon of baking soda and no baking powder, which clearly results in darker speckles.

This much lighter buttermilk banana bread only has 1/8 teaspoon baking soda (and a teaspoon of baking powder). You can see the difference!

Sour Cream Banana Bread FAQs

Can I make this recipe into muffins?

Many readers over the years have done just that. They’ve reported back with good results. The recipe will yield about 17-20 muffins (bake them at the same temp in the recipe and check them around 17-18 minutes).

Can I sub the sour cream with buttermilk or plain milk?

Buttermilk can be used in place of the sour cream (the batter will be thinner, but that’s ok). Subbing in dairy milk or non-dairy milk for the sour cream may affect the texture and overall end result of the bread because the recipe needs the acidity of the sour cream (or buttermilk) to turn out correctly.

Can I add nuts, chocolate chips or other add-ins?

Yes, that works great! Toss them in with the flour (just remember not to over mix!).

Sour Cream Banana Bread

4.66 stars (1153 ratings)

Ingredients

  • 1 cup (212 g) granulated sugar (see note to reduce the sugar)
  • ½ cup oil (see note)
  • 2 eggs
  • 1 cup (227 g) mashed ripe bananas, about 3 ripe bananas
  • ½ cup (113 g) sour cream
  • 1 teaspoon vanilla
  • 1 ½ cup (213 g) all-purpose flour (see note)
  • 1 teaspoon baking soda
  • ½ teaspoon salt

Instructions 

  • Preheat the oven to 350 degrees F.
  • Grease and flour a 9X5-inch loaf pan (or several mini loaf pans).
  • In a large bowl, whisk together the sugar and oil. Add the eggs, bananas, sour cream and vanilla; blend well.
  • Add the flour, baking soda and salt; stir just until dry ingredients are moistened. Spread the batter evenly in the prepared pan.
  • Bake for 50-60 minutes until toothpick inserted in the center of the loaf comes out clean.
  • Cool for five minutes in the pan. Gently turn out onto a cooling rack and cool completely. Store covered at room temperature (the bread also freezes great).

Notes

Variations: I often sub applesauce for part of the oil (up to half) and sometimes use melted butter in place of the oil), use 50% whole wheat flour, decrease the sugar to 3/4 cup (especially if using very ripe bananas), and very often, I double the recipe and make two loaves because it freezes great. 
Flour: don’t pack the flour in the measuring cup. Fluff up the flour really well, scoop, and level.
