Step-by-step
- Prep
Heat oven to 350°F. Line a 9×5-inch loaf pan with parchment leaving overhang. - Mash & mix
In a large bowl mash bananas smooth. Whisk in melted butter, sour cream, sugars, eggs, and vanilla. - Dry ingredients
Sprinkle flour, baking soda, baking powder, salt, and cinnamon over the wet mixture. Fold just until a few flour streaks remain. Fold in nuts if using. - Bake
Spread into the pan and smooth the top. Bake 55 to 65 minutes, until a toothpick comes out with a few moist crumbs (the top should spring back). - Cool
Cool in pan 15 minutes, then lift out and cool fully before slicing thick.
Pro tips
- Use bananas that are very spotty or nearly black for the best sweetness and aroma.
- Weigh or spoon-and-level flour to avoid a dense loaf.
- Don’t overmix; stop as soon as flour disappears.
- Tent with foil at minute 40 if the top browns too fast.
- For a taller crown, let the batter rest 10 minutes in the pan before baking.
Variations
- Banana Nut Bread: fold in ¾ cup toasted chopped walnuts or pecans.
- Chocolate Chip Banana Bread: swap nuts for ¾ cup mini chocolate chips.
- Cinnamon Swirl: layer half the batter, sprinkle 2 tbsp brown sugar + 1 tsp cinnamon, then top with remaining batter.
- Muffins: portion into 12 cups, bake at 350°F for 18 to 22 minutes.
How to serve
Thick slices slightly warm with butter; excellent toasted for breakfast; great with coffee or a glass of milk. For dessert, add a drizzle of honey or a swipe of cream cheese.
Make ahead & storage
- Room temp: Wrap airtight; keeps 3 to 4 days.
- Freeze: Slice, wrap individually, and freeze up to 3 months; thaw at room temp or toast from frozen.
- Reheat: 300°F oven 8 to 10 minutes or toaster until edges are lightly crisp.
FAQs
Why is my banana bread dry?
Too much flour or overbaking. Spoon-and-level flour and pull when a toothpick has moist crumbs.
Can I use oil instead of butter?
Yes. Use ½ cup neutral oil; flavor is a bit milder, crumb even moister.
Do I need a mixer?
No. A whisk and spatula are perfect for this one-bowl batter.
Can I reduce the sugar?
Yes, reduce to ¾ cup total; loaf will be less caramelized but still moist.
