Don’t Over Mix

As with all good quick bread recipes, one important key to this recipe is to mix just until the dry ingredients are incorporated.

Over mixing the batter could mean death to a lovely, soft, moist loaf of perfect banana bread.

Easily Doubled

This recipe makes one loaf of banana bread. But it is easily doubled, and I highly encourage you to do so.

In fact, I often buy several bunches of bananas just to let them ripen in destruction on my kitchen counter to prepare for this amazing recipe.

What Causes the Speckles in Banana Bread?

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

I’ve done a lot of reading and testing (I’m telling you, NERD, and proud of it) to figure out why some banana bread loaves have a light-colored crumb and other recipes produce the dark speckles like you see in these pictures.

The reason? Baking soda.

Banana bread recipes that have a larger amount of 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…and it clearly results in darker speckles.

This much lighter buttermilk banana bread only has 1/8 teaspoon baking soda (and a teaspoon of baking powder).

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

4.63 stars (1039 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.
