Step-by-Step Instructions

1. Prep & Pan: Preheat oven to 350°F (175°C). Grease a loaf pan with butter or line it with parchment.
2. Combine Wet Ingredients: Mash 3 ripe bananas in a bowl. Mix in ½ cup melted butter, ¾ cup brown sugar, ½ cup sour cream, 2 eggs, and 1 tsp vanilla.
3. Dry Mix: In a separate bowl, whisk 1½ cups flour, 1 tsp baking soda, and ½ tsp salt.
4. Fold Together: Gently mix wet and dry ingredients until just combined (overmixing = dense loaf!).
5. Bake: Pour batter into the pan. Bake 55–65 minutes, or until a toothpick comes out clean.
6. Cool: Let cool in the pan for 10 minutes, then transfer to a rack.
Pro Tip: Adding sour cream ensures this Sour Cream Banana Bread stays far moister than typical banana dessert recipes. For a decadent twist, sprinkle cinnamon sugar on top before baking!
Troubleshooting & Pro Tips
– Too dense? Avoid overmixing – stir until streaks of flour disappear.
– Undercooked center? Tent foil over the loaf after 40 minutes to prevent browning.
– No ripe bananas? Bake unpeeled bananas at 300°F for 15 minutes to soften.
– Want nuts/chocolate? Fold in ½ cup walnuts or chocolate chips after mixing!
Storage & Make-Ahead Tips
– Room Temp: Keep wrapped tightly for 2 days.
– Fridge: Store for up to 5 days.
– Freeze: Slice loaf, wrap in plastic, and freeze for 3 months. Thaw at room temp or toast lightly.
