Why you’ll love sour cream banana bread

  • Have excess bananas? Instead of throwing away food (and money), banana bread transforms overripe fruit into something delicious, and this recipe is proof of that. 
  • It freezes beautifully, making it a convenient make-ahead snack you can pull out and serve whenever needed.
  • The addition of sour cream instantly elevates flavor by adding moisture, activating baking soda for a better rise, and using its acidity to amplify the banana taste while cutting through the sweetness.

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. Chopped pecans also work great according to a reader who tried this recipe!

How do you make this sour cream banana bread? 

banana bread batter

Prepare the batter:

  1. Preheat the oven to 350 degrees F. Grease and flour a 9 × 5 × 2.5–3 inches loaf pan. 
  2. In a large bowl, cream the butter and sugar, then mix in the eggs. 
  3. In a separate bowl, combine the flour, baking soda, and salt. Combine with the butter mixture. 
  4. Add the sour cream, mashed bananas, and vanilla. Stir well. 

PRO TIP: Be careful that you don’t overmix the bread batter or you will create an overly dense bread loaf.

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 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.  
  • 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. 
  • How to ripen bananas: To quickly ripen bananas for this 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. 
  • Muffins: Make regular or jumbo 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 fruity bread. 
  • Gluten-free: Use a 1:1 gluten-free flour blend, and add 1/2 teaspoon of xanthan gum if needed. The bread still comes out remarkably moist according to one of my readers!
  • Add a sweet topping: For a sweeter option, top the baked and cooled bread with a simple vanilla icing/glaze or a luxurious frosting.
