Moist Sour Cream Banana Bread Recipe

August 20, 2025

This moist sour cream banana bread is perfect for using up ripe bananas! Combining sweet bananas with sour cream gives it a soft and fluffy texture that’s hard to resist.

Honestly, the smell of it baking fills the house with warmth. It makes for a sweet breakfast treat or an afternoon snack. I love to enjoy it slightly warm with a pat of butter—heavenly! 🍌

Key Ingredients & Substitutions

All-purpose flour: This flour gives structure to your banana bread. If you’re looking for alternatives, whole wheat flour works too but may make the bread denser. Gluten-free all-purpose flour can be used as well for a gluten-free version!

Sour cream: This is crucial for moisture and tang. You can substitute it with Greek yogurt for a similar effect or buttermilk if you have it on hand. Both options will still keep your bread nice and moist!

Bananas: The riper the bananas, the better! They should be brown and spotty for maximum sweetness. If you’re short on time, you can mash your bananas and microwave them for 30 seconds to soften them quickly, but fresh is always best.

Nuts: I love throwing in some walnuts or pecans for added texture. If you’re nut-free, feel free to skip them or use chocolate chips for a sweeter twist!

How Do I Ensure My Banana Bread is Moist and Fluffy?

To achieve that perfect moist and fluffy texture, follow these tips:

  • Do not overmix the batter! Mix just until you see no dry flour. This helps keep the bread light.
  • Use mashed ripe bananas—these have the best flavor and natural sweetness.
  • Make sure your butter is softened but not melted; this gives the right consistency when creaming it with sugar.
  • Check your bread a few minutes early; oven times can vary. A toothpick should come out clean but slightly moist when it’s done.

These small details can make a big difference, helping you nail that perfect banana bread every time! Enjoy baking and tasting your delicious creation!

Moist Sour Cream Banana Bread Recipe

Ingredients You’ll Need:

  • 1 ½ cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ⅓ cup unsalted butter, softened
  • ½ cup granulated sugar
  • ½ cup brown sugar, packed
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • ½ cup sour cream
  • 1 cup ripe bananas, mashed (about 2-3 medium bananas)
  • Optional: ½ cup chopped walnuts or pecans

How Much Time Will You Need?

This banana bread takes about 15 minutes to prepare and 60-70 minutes to bake. With a little time to cool after baking, you can enjoy your freshly made loaf in about 1 hour and 30 minutes from start to finish!

Step-by-Step Instructions:

1. Prepare the Oven and Pan:

Start by preheating your oven to 350°F (175°C). While that’s warming up, take a 9×5-inch loaf pan and lightly grease and flour it. This will help your banana bread slide out easily when it’s done baking.

2. Mix Dry Ingredients:

In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. This helps ensure even distribution of the baking soda and salt throughout the flour. Once those are mixed, set this bowl aside while you prepare the wet ingredients.

3. Cream the Butter and Sugars:

In a large bowl, cream the softened unsalted butter with the granulated sugar and brown sugar. Use an electric mixer on medium speed until the mixture is light and fluffy. This should take about 2-3 minutes. It’s the key to a fluffy, delicious loaf!

4. Add Eggs and Vanilla:

Beat in the eggs, adding one at a time. Make sure to mix well after each addition. Then, stir in the vanilla extract for flavor. Your batter should be starting to come together nicely now!

5. Combine Banana and Sour Cream:

Next, mix in the sour cream and the mashed ripe bananas. Stir this until everything is combined. The bananas will add sweetness, moisture, and that wonderful flavor we all know and love.

6. Combine Dry Ingredients with Wet:

Gradually add your dry mixture to the wet mixture. Stir gently just until you see no more flour. It’s important not to overmix; this keeps your bread tender and fluffy!

7. Fold in Nuts (if using):

If you’re adding nuts, now is the time to fold in the chopped walnuts or pecans. This is optional, but it gives a lovely crunch to the banana bread.

8. Pour and Smooth the Batter:

Pour the batter into your prepared loaf pan and use a spatula to smooth the top. This helps the bread rise evenly as it bakes.

9. Bake:

Bake in your preheated oven for 60-70 minutes. You’ll know it’s done when a toothpick inserted into the center comes out clean or with just a few crumbs attached.

10. Cool and Enjoy:

Once baked, remove the loaf from the oven and let it cool in the pan for about 10 minutes. Then transfer the loaf to a wire rack to cool completely before slicing. This resting time helps the flavors develop further!

Enjoy your moist and tender sour cream banana bread any time of day! It’s great fresh out of the oven or toasted with a little butter.
