Ingredients needed to make sour cream banana bread
- Butter: Unsalted butter will give you better control of the level of salt in this recipe, but you could use salted butter instead. Allow the butter to soften at room temperature for easy mixing.
- Sugar: Feel free to use only granulated sugar or a combination of granulated sugar (for sweetness and a delicious crust on the top of the banana bread) and brown sugar (for moisture and a caramel-like flavor).
- Eggs: Allow your eggs to reach room temperature before beating. For an egg-free bread, use 1/4 cup unsweetened applesauce per egg.
- Flour: My go-to flour for this sour cream banana bread is all-purpose flour. For a lighter texture, substitute 1 cup with cake flour.
- Baking soda: Reacts with the sour cream’s acidity for the perfect rise.
- Salt: Enhances the flavors in this bread. Omit when using salted butter.
- Mashed bananas: Use 3 ripe bananas for this banana bread. The riper the better for a deliciously sweet and moist bread with stronger banana flavor.
- Sour cream: Provides moisture to the bread batter and offers a lovely tang to balance the sweet flavors. You could use Greek yogurt instead.
- Vanilla extract: For added depth of flavor. Add 1/2 teaspoon of almond extract for nutty notes, if desired.
- Walnuts: The perfect addition to any banana bread recipe, offering delicious crunch and nutty flavor throughout.

How do you make this sour cream banana bread?
Prepare the batter:
- Preheat the oven to 350 degrees F. Grease and flour a 9-inch loaf pan.
- In a large bowl, cream the butter and sugar, then mix in the eggs.
- In a separate bowl, combine the flour, baking soda, and salt. Combine with the butter mixture.
- Add the sour cream, mashed potatoes, and vanilla. Stir well.

Bake the banana bread:
- Pour the batter into the prepared pan so that the pan is ¾ full and bake for 50-55 minutes.

Cool and slice:
- Cool the baked bread for at least 10 minutes in the pan before turning out on a rack.
- Slice and serve!

Serving
Serve your sour cream banana bread with regular butter or Sweet Spiced Apple Butter, homemade or store-bought jam, or whipped cream for a bit of decadence!
This moist and comforting banana bread also makes the ideal addition to your breakfast spread, alongside a bowl of Coconut Almond Granola, this Breakfast Fresh Fruit Yogurt Platter, a mug of hot coffee or a cozy Pumpkin Spice Latte.

Sandy’s tips and substitutions:
- Storage: Store leftover sour cream banana bread in an airtight container at room temperature for up to 4 days or in the fridge for up to 7 days.
- Freezing: Wrap individual slices of this banana bread in foil and then transfer them to a Ziploc bag. Your banana bread will last for up to 3 months and can be thawed later at room temperature before serving as is or lightly toasted.
- Don’t overmix: Be careful that you don’t overmix the bread batter or you will create an overly dense bread loaf.
- Test for doneness: Insert a toothpick into the center of the loaf. It should return clean. If you see wet batter, return the pan to the oven and bake for an additional 5-10 minutes.
- Cover with foil: If the top of your bread is browning too quickly in the oven, simply cover it with foil.
- How to ripen bananas: To quickly ripen bananas for this sour cream banana bread, place them in a paper bag on a warm counter. The bag traps the natural ethylene gas the fruit emits, which significantly speeds up the ripening process.

Variations:
- Spices: For a touch of warmth, add a mixture of cardamom, ginger, and nutmeg to the banana bread batter.
- Sour cream banana bread muffins: Make muffins by baking the batter in muffin molds. You will need to reduce the baking time to about 20-25 minutes at the same oven temperature.
- Loaf pan size: You can either bake one large banana bread in a standard 9-inch loaf pan for 50-55 minutes or three smaller loaves in small loaf pans at the same oven temperature for 35 minutes.
- Fruity twist: Banana pairs well with a variety of fruit. Feel free to add in strawberries, pineapple, pears, dates, like I’ve done in my Hawaiian Banana Bread, Strawberry Banana Bread, and Healthy Banana Bread with Dates.
- Mix-ins: Chocolate chips, shredded coconut, and seeds are delicious additions to this sour cream banana bread.
- Gluten-free: Use a 1:1 gluten-free flour blend, and add 1/2 teaspoon of xanthan gum if needed.
- Add a sweet topping: For a sweeter option, top the baked and cooled sour cream banana bread with a simple vanilla icing/glaze or a luxurious frosting.

Sandy, this is the best banana bread ever. Super moist. I use plain yogurt and add toasted walnuts. I could eat the whole loaf myself . My Aunt Evie as a Iowa farm mom, told me she’s the original Reluctant Entertainer .
Awh … that is very sweet. Hello to your Aunt Evie! Glad you enjoyed the recipe.
I haven’t made it yet because I have a question. Can you substitute a baking sugar alternative like Splenda for the sugar?? I can’t wait to make this recipe!! Thanks!
Hi Leslie, I’ve never tried Spenda. Let me know if it works!
Good recipe, but the temp seems a bit high. The outside got borderline burnt by the time the inside fully cooked.
Sorry to hear that Amber. We’ve tested this recipe over and over (and read all the reviews), which makes me think it might be your oven! Anyway, I hope you enjoyed the recipe.
Excellent! Love the sour cream. I even added more (I soak my flour overnight first, and it needed a little more for that, but it still turned out well). I made a similar recipe in the past where I noted that “it seems to need a little more butter” and yours proves it. Your recipe has 33% more butter than the one I made before, and is just perfect. Since the fat gives the wonderful mouth feel I have a hard time imaging substituting apple sauce. This will be a new favorite.
Could you substitute some of the butter with olive oil or apple sauce or additional Greek yogurt? Thanks
Probably with applesauce! But I haven’t tried it, so come back and let us know! :)
The. Best. banana. bread. EVER! Just made another double batch…..will do another this weekend. (Everyone loves it.)Thank you for this recipe. I’m convinced that the sour cream is the secret ingredient!
Used Greek yogurt absolutely the best banana bread ever!
Recipe is a keeper
The best recipe hands down! I even added about 1/3 cup buttermilk and a dash of cinnamon, delicious!
By far, The Best ‘Nana Bread recipe Ever! The sour cream makes all the difference.
Do you think i can use pumpkin purée instead of banana?
I have not tried this, but I do think pumpkin would work, too!
