There is a reason banana bread with sour cream is the version people come back to: the sour cream keeps the crumb soft, tender and moist from the first slice to the last.
Quick answer
For moist banana bread with sour cream, whisk 3 mashed overripe bananas with melted butter, white and brown sugar, 2 eggs, 1 cup sour cream and vanilla, then fold in flour, baking soda, baking powder, salt and cinnamon. Bake in a 9×5 loaf pan at 350°F for 55 to 65 minutes.

Why Sour Cream Makes Banana Bread So Moist
The secret to a truly moist banana bread is fat and acid, and sour cream brings both. The fat coats the flour and keeps the crumb soft for days. The acidity reacts with the baking soda, giving a better rise and a lighter texture that balances the natural density of bananas.
It also changes the flavor in a way that is easy to taste and hard to name: a gentle tang that rounds out the sweetness and makes the banana taste more like banana. And because sour cream holds its moisture, the loaf is just as soft on day three as on day one.
Moist for days
Sour cream holds moisture far longer than milk or water.
Tender crumb
Fat keeps it soft; acid helps it rise light.
Crackled top
A sugar-rich batter bakes into a crisp, golden crust.
One bowl
No mixer, just a whisk and a spatula.

Instructions
Prep the pan
Heat the oven to 350°F. Grease the loaf pan and line it with parchment, leaving an overhang on the long sides (or line a muffin tin).
Mash the bananas
Mash the bananas in a large bowl until only small lumps remain.
Mix the wet ingredients
Whisk in the melted butter and both sugars until glossy, then the eggs one at a time, then the sour cream and vanilla until smooth.
Add the dry ingredients
Add the flour, baking soda, baking powder, salt and cinnamon and fold with a spatula just until no dry streaks remain. Fold in the walnuts.
Fill and bake
Scrape into the pan, smooth the top and run a shallow line down the center for an even split. Bake until a toothpick comes out with a few moist crumbs (see the card for time), tenting with foil at 40 minutes if the top browns fast.
Cool
Cool 15 minutes in the pan, lift out by the parchment and cool completely on a rack before slicing.

How Ripe Should the Bananas Be?
| Peel | Ready? | Result |
|---|---|---|
| PeelGreen-yellow | Ready?No | ResultStarchy, bland, hard to mash |
| PeelAll yellow | Ready?Not yet | ResultMild flavor, a drier loaf |
| PeelHeavily speckled | Ready?Yes | ResultSweet, fragrant, easy to mash |
| PeelFully black | Ready?Best | ResultThe sweetest, most intense banana flavor |
The riper the better. Bananas that look past eating are perfect here. To speed things up, bake unpeeled bananas on a sheet at 300°F for 15 to 20 minutes until the skins turn black, then cool them. Frozen bananas work too; thaw them and use the liquid that comes out, which is pure banana flavor.
How to Make It Step by Step
Everything goes into one bowl.
Mash the bananas in a large bowl until mostly smooth with a few small lumps. Whisk in the melted, slightly cooled butter and both sugars until glossy, then the eggs one at a time, then the sour cream and vanilla. The wet mixture should look thick and smooth.
Add the flour with the baking soda, baking powder, salt and cinnamon sprinkled over it, and switch to a spatula. Fold just until the last streak of flour disappears. Overmixing after the flour goes in develops gluten and makes a tough, rubbery loaf. Fold in the walnuts with a few extra strokes.
Scrape the batter into the parchment-lined pan and smooth the top. A shallow line drawn down the center with a knife gives the loaf a neat, even split as it rises.
How to Know It Is Done

| Check | Done when |
|---|---|
| CheckToothpick | Done whenComes out with a few moist crumbs, no wet batter |
| CheckInternal temperature | Done when200 to 205°F in the center |
| CheckTop | Done whenDeep golden and springs back when pressed |
| CheckSides | Done whenPulling slightly away from the pan |
Ovens vary, so start checking at 50 minutes. If the top is browning faster than the center is baking, lay a loose sheet of foil over it at about 40 minutes. Cool 15 minutes in the pan, then lift it out by the parchment and let it cool completely before slicing; a hot loaf is still setting and slices gummy.
