Moist Sour Cream Banana Bread

Sour cream is the secret weapon in banana bread. It does two jobs at once: the lactic acid wakes up the baking soda for a higher rise, and the fat coats flour proteins so the crumb stays plush instead of going dry by day two.

Use bananas that look like they belong in the trash. Black skins, soft fruit, sweet smell. Underripe bananas give a starchy loaf with no flavor.

Cream the butter and sugar properly before adding eggs. You’re building structure here. Then alternate the dry mix and the mashed bananas with sour cream so the gluten doesn’t toughen up. Fold in pecans or walnuts last for crunch.

A full hour at moderate heat lets the center cook without burning the edges. Tent with foil at 45 minutes if the top browns too fast.

Pro Tips

• Three medium bananas equal one cup mashed. Weigh if you can, since too much fruit makes a gummy loaf.
• Test with a skewer in the center, not the side. Banana bread sets last in the middle.
• Rest the loaf in the pan ten minutes, then turn out onto a rack so the bottom doesn’t steam.
• Wrap cooled bread in plastic and let it sit overnight. The flavor deepens dramatically by morning.

Variations

• Stir in a half cup of chocolate chips for a dessert-leaning loaf.
• Swap half the sugar for brown sugar and add a teaspoon of cinnamon for extra warmth.
• Top with a streusel of butter, brown sugar, and oats before baking for crunch on top.
