Ingredients You’ll Need

This recipe uses pantry staples and a few fresh ingredients you likely already have on hand.

  • 1/2 cup (1 stick) unsalted butter, softened
  • 1/2 cup granulated sugar
  • 1/2 cup packed brown sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 1 cup mashed ripe bananas (about 2–3 medium bananas)
  • 1 cup all-purpose flour
  • 1/2 cup old-fashioned oats, blended into a powder
  • 1 teaspoon baking soda
  • 1 1/2 teaspoons baking powder
  • 3/4 teaspoon kosher salt
  • 1/2 cup sour cream
  • 1/4 teaspoon ground cinnamon (optional)
  • 1/8 teaspoon ground nutmeg (optional)
  • 1/8 teaspoon ground cloves (optional)
  • 1/2 to 3/4 cup chopped toasted pecans or walnuts (optional)

How to Make Moist Banana Bread with Sour Cream

Step 1: Prepare Your Baking Pan

  • Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan or line it with parchment paper for easy removal.

Step 2: Toast the Nuts (Optional)

  • If using nuts, spread them on a baking sheet and toast them in the oven for 5–7 minutes, stirring halfway through. Toasting enhances their flavor and adds a delightful crunch.

Step 3: Mash the Bananas

  • In a small bowl, mash the bananas with a fork or potato masher until smooth. Ensure you have 1 cup of mashed bananas for the perfect texture and flavor.

Step 4: Cream the Butter and Sugars

  • In a large mixing bowl, use an electric mixer to beat the softened butter, granulated sugar, and brown sugar until light and fluffy. This step is key for creating a tender crumb.

Step 5: Add the Eggs and Vanilla

  • Beat in the eggs one at a time, ensuring each is fully incorporated. Stir in the vanilla extract for added depth of flavor.

Step 6: Combine Wet and Dry Ingredients

  • In a separate bowl, whisk together the all-purpose flour, powdered oats, baking soda, baking powder, salt, and optional spices. Gradually add the dry mixture to the wet ingredients, mixing just until combined.

Step 7: Fold in Sour Cream and Nuts

  • Gently fold in the sour cream to create a silky batter. If using, stir in the toasted nuts for added texture and flavor.

Step 8: Bake the Bread

  • Pour the batter into the prepared loaf pan, smoothing the top with a spatula. Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean.

Step 9: Cool and Serve

  • Allow the bread to cool in the pan for 10 minutes before transferring it to a wire rack. Let it cool completely before slicing to ensure clean, even slices.

Helpful Tips for Success

  • Use Ripe Bananas: The riper the bananas, the sweeter and more flavorful your bread will be. Look for bananas with lots of brown spots or even completely blackened skins.
  • Don’t Overmix: Overmixing the batter can lead to dense banana bread. Mix just until the ingredients are combined.
  • Customize Your Bread: Love chocolate? Add 1/2 cup of chocolate chips. Prefer a tropical twist? Add shredded coconut or dried pineapple.
  • Room-Temperature Ingredients: Ensure your butter and eggs are at room temperature for easier mixing and a more uniform batter.
