Full Recipe:

Ingredients

  • ½ cup butter, softened

  • ½ cup brown sugar, packed

  • ½ cup granulated sugar

  • 2 large eggs

  • 2 teaspoons vanilla extract

  • 1 cup mashed ripe banana (about 2 ½ medium bananas)

  • 1 cup all-purpose flour, spooned and leveled

  • ½ cup old-fashioned oats, blended into powder

  • 1 teaspoon baking soda

  • 1 ½ teaspoons baking powder

  • ¾ teaspoon kosher salt

  • ½ cup sour cream

  • ¼ teaspoon cinnamon (optional)

  • ⅛ teaspoon nutmeg (optional)

  • ⅛ teaspoon cloves (optional)

  • ½ to ¾ cup toasted pecans or walnuts (optional)

Directions

  1. Preheat and Prepare: Preheat your oven to 350°F (175°C). Spray a 9×5-inch loaf pan with nonstick spray or line it with parchment paper. If using nuts, toast them in the oven for 5-7 minutes at 350°F, then set aside to cool.

  2. Mix Wet Ingredients: In a large bowl or stand mixer, beat the softened butter until smooth. Add both sugars and beat until fluffy for about 2 minutes. Add the eggs and vanilla extract, mixing well after each addition.

  3. Mash the Bananas: In a separate bowl, mash the bananas using a fork or potato masher until smooth. Add the mashed bananas to the wet mixture and stir until incorporated.

  4. Combine Dry Ingredients: In another bowl, mix together the flour, oats (blended into a powder), baking soda, baking powder, salt, and optional spices (cinnamon, nutmeg, cloves). Gradually add the dry ingredients to the wet ingredients, stirring until just combined.

  5. Add Sour Cream: Fold in the sour cream, and if desired, mix in the toasted nuts.

  6. Bake: Pour the batter into the prepared loaf pan and smooth out the top. Bake for 55-65 minutes, or until a toothpick inserted into the center comes out clean with a few moist crumbs.

  7. Cool: Let the bread cool in the pan for about 20 minutes, then transfer to a wire rack to cool completely before slicing.

Why Moist and Fluffy Banana Bread with Sour Cream Works So Well

What sets this banana bread apart from other recipes is the use of sour cream, which adds moisture and helps to create a light, tender crumb. The texture is fluffy, not heavy, thanks to the sour cream’s ability to balance the sweetness of the bananas and sugar while preventing the bread from becoming too dense. The flavor is rich, with the bananas providing a natural sweetness that’s enhanced by a blend of spices like cinnamon, nutmeg, and cloves (optional), which add warmth and complexity.

The combination of mashed bananas, oats, and flour gives the bread structure, while the baking soda and baking powder ensure it rises properly, creating the perfect balance of texture and flavor. Whether you choose to add toasted nuts for extra crunch or keep it simple, this banana bread is always a crowd-pleaser.

The Ingredients: Simple but Effective

The ingredients for this banana bread are simple, yet each one plays an important role in creating the perfect loaf. The butter and sugars create a rich base, while the eggs and vanilla add depth and moisture. The mashed ripe bananas are the star of the show, providing both flavor and moisture to the bread.

Blending the oats into a powder adds a subtle flavor and texture to the bread without making it too dense. The combination of baking soda, baking powder, and salt ensures that the bread rises properly while keeping its tender texture. The sour cream is the key to achieving the light, moist crumb that makes this banana bread so irresistible.

The optional spices—cinnamon, nutmeg, and cloves—add a warm, comforting fragrance to the bread, enhancing the banana flavor. The addition of toasted pecans or walnuts is optional, but they bring a delightful crunch and nuttiness to the bread, offering a nice contrast to the softness of the banana.

Preparing the Banana Bread: Simple Steps for Success

Making this banana bread is easy and requires just a few steps. The first step is to cream the butter and sugars together until light and fluffy. This process helps to aerate the mixture, which is important for creating a fluffy texture in the final bread. Adding the eggs and vanilla extract, one at a time, ensures that everything is well incorporated.

Once the bananas are mashed, they are added to the wet ingredients, and the mixture is stirred until smooth. In a separate bowl, the dry ingredients—flour, oats, baking soda, baking powder, salt, and optional spices—are mixed together before being gradually added to the wet ingredients. Stirring just until combined prevents overmixing, which can lead to a denser bread.

The sour cream is folded into the batter at the end, adding moisture and richness to the bread. If you’re adding toasted nuts, they can be mixed in at this stage as well.

Baking the Banana Bread: Perfectly Golden

Once the batter is prepared, it’s poured into a greased 9×5-inch loaf pan and smoothed out. The bread is then baked at 350°F (175°C) for 55–65 minutes, or until a toothpick inserted into the center comes out clean with just a few moist crumbs. The baking time may vary slightly depending on your oven, so it’s important to start checking the bread at the 55-minute mark.

If the bread starts to brown too quickly on top, you can tent it with foil to prevent overbrowning. The result will be a golden, perfectly risen loaf that’s soft and fluffy on the inside.

Cooling and Serving: Let the Bread Rest

Once the bread is done baking, it’s important to let it cool in the pan for about 20 minutes before transferring it to a wire rack to cool completely. This resting period allows the bread to set and makes it easier to slice. Once cooled, slice the banana bread into thick pieces and enjoy.

This banana bread is delicious on its own, but it can also be enjoyed with a dollop of butter, a drizzle of honey, or a spread of peanut butter for an added treat. It’s perfect for breakfast with a cup of coffee or as an afternoon snack.
