For foolproof banana bread with sour cream, follow these simple steps:
1. Prep: Preheat oven to 350°F (175°C). Grease your loaf pan.
2. Mash bananas: In a medium bowl, mash 3 overripe bananas until mostly smooth.
3. Mix wet ingredients: Whisk bananas with ½ cup sour cream, 2 eggs, 1 tsp vanilla, and ½ cup melted butter.
4. Combine dry ingredients: In a separate bowl, mix 1½ cups flour, ¾ cup brown sugar, 1 tsp baking soda, and ½ tsp salt.

Troubleshooting & Pro Tips
– Sinking middle? Avoid overmixing—this develops gluten, which traps air and collapses.
– Too dense? Ensure baking soda is fresh.
– Extra moisture: Add ½ cup chopped walnuts or chocolate chips for texture.
– Ripen bananas faster: Bake unpeeled bananas at 300°F for 15–20 minutes.
Storage & Make-Ahead Tips
– Store cooled bread wrapped in foil at room temperature for 3 days.
– Freeze: Slice and freeze for up to 3 months. Reheat in a toaster oven.
– Make-ahead: Prepare batter (without baking soda) and refrigerate overnight. Add baking soda just before baking.
