This sour cream banana bread is a delightful twist on the classic banana bread recipe. The addition of sour cream makes the bread incredibly moist and tender, while the ripe bananas add natural sweetness and flavor. Perfect for breakfast, a snack, or even dessert, this bread is sure to become a family favorite.
While most of the ingredients for this recipe are common pantry staples, you might need to pick up sour cream if you don't usually keep it on hand. Additionally, make sure your bananas are ripe, as they will be easier to mash and provide the best flavor. Everything else should be readily available at your local supermarket.

Ingredients For Sour Cream Banana Bread
Butter: Adds richness and moisture to the bread.
Sugar: Sweetens the bread and helps with browning.
Eggs: Provide structure and stability to the batter.
Bananas: The star ingredient, adding natural sweetness and flavor.
Sour cream: Makes the bread extra moist and tender.
Vanilla extract: Enhances the overall flavor of the bread.
Baking soda: Helps the bread rise and become fluffy.
Salt: Balances the sweetness and enhances the flavors.
All-purpose flour: Forms the base of the bread, providing structure.
Technique Tip for This Recipe
When creaming the butter and sugar together, ensure the butter is at room temperature. This allows it to incorporate air more effectively, resulting in a lighter and fluffier banana bread. If the butter is too cold, it won't mix well, and if it's too warm, it can make the batter greasy.
Suggested Side Dishes
Alternative Ingredients
butter - Substitute with coconut oil: Coconut oil provides a similar fat content and moisture, giving the bread a subtle coconut flavor.
sugar - Substitute with honey: Honey adds natural sweetness and moisture, though it may slightly alter the flavor profile.
eggs - Substitute with flax eggs: Mix 1 tablespoon of ground flaxseed with 3 tablespoons of water per egg. This is a great vegan alternative that helps bind the ingredients.
bananas - Substitute with applesauce: Applesauce can provide similar moisture and sweetness, though the banana flavor will be absent.
sour cream - Substitute with Greek yogurt: Greek yogurt offers a similar tangy flavor and creamy texture, maintaining the moisture of the bread.
vanilla extract - Substitute with almond extract: Almond extract gives a different but pleasant flavor, though it is stronger, so use half the amount.
baking soda - Substitute with baking powder: Use 3 times the amount of baking powder, but note that it may slightly affect the texture.
salt - Substitute with sea salt: Sea salt can be used in the same quantity and provides a similar flavor.
all-purpose flour - Substitute with whole wheat flour: Whole wheat flour adds a denser texture and a slightly nutty flavor, along with more nutrients.

How to Store / Freeze This Banana Bread
- To keep your sour cream banana bread fresh and moist, wrap it tightly in plastic wrap or aluminum foil. This will prevent it from drying out and help maintain its delicious texture.
- For an extra layer of protection, place the wrapped bread in an airtight container or a resealable plastic bag. This will keep it fresh for up to 3-4 days at room temperature.
- If you prefer to refrigerate your banana bread, follow the same wrapping steps and store it in the fridge. This can extend its freshness for up to a week. Just remember to let it come to room temperature before serving for the best flavor and texture.
- To freeze, first allow the banana bread to cool completely. This prevents condensation from forming inside the wrapping, which can lead to freezer burn.
- Wrap the cooled bread tightly in plastic wrap, followed by a layer of aluminum foil. This double wrapping helps protect the bread from freezer burn and preserves its flavor.
- For added convenience, you can slice the bread before freezing. Place a piece of parchment paper between each slice to prevent them from sticking together. Then, wrap the slices as described above.
- Label the wrapped bread with the date and type of bread. This will help you keep track of how long it has been in the freezer.
- Store the wrapped bread in a freezer-safe bag or container. This will provide an extra layer of protection against freezer burn and help maintain the bread's quality.
- When you're ready to enjoy your frozen banana bread, simply remove it from the freezer and let it thaw at room temperature. If you’re in a hurry, you can also reheat individual slices in the microwave for about 20-30 seconds.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Wrap the banana bread in aluminum foil to prevent it from drying out. Place it on a baking sheet and heat for about 10-15 minutes, or until warmed through.
For a quicker method, use a microwave. Place a slice of banana bread on a microwave-safe plate. Cover it with a damp paper towel to retain moisture. Heat on medium power for 20-30 seconds. Check and add more time if necessary.
If you have a toaster oven, set it to 350°F (175°C). Wrap the banana bread in foil and place it in the toaster oven. Heat for 10-15 minutes, checking periodically to ensure it doesn’t overheat.
For a stovetop method, use a non-stick skillet. Heat the skillet over medium-low heat. Place a slice of banana bread in the skillet and cover with a lid. Heat for about 2-3 minutes on each side, or until warmed through.
If you prefer a slightly crispy texture, use a toaster. Slice the banana bread and toast it on a low setting. Keep an eye on it to prevent burning. This method works well if you enjoy a bit of crunch with your banana bread.
