Banana bread is the best thing you can do with bananas that are too spotty to eat. This moist banana bread recipe is tender and full of banana flavor. It's made in one bowl with a fork and a spatula. No mixer.

The two things that matter most: very ripe bananas and not overmixing. Get those right and the loaf will turn out well.

How ripe should the bananas be?

Riper than you think. The peels should be heavily spotted, mostly brown, even nearly black. As bananas ripen, their starch turns to sugar. That means more sweetness and much stronger banana flavor.

Yellow bananas with a few spots will work, but the bread will taste milder and be less moist.

Speed-ripening trick: put unpeeled bananas on a baking sheet and bake at 300°F for 15 to 20 minutes, until the skins turn black. Let them cool before using. They'll be soft and sweet, though the flavor isn't quite as deep as naturally ripened ones.

Ingredients

For one 9x5-inch loaf:

• 3 large very ripe bananas (about 1 1/2 cups mashed)
• 1/2 cup (113 g) unsalted butter, melted
• 3/4 cup (150 g) packed light brown sugar
• 1 large egg, room temperature
• 1 tsp vanilla extract
• 1/4 cup (60 g) sour cream or plain Greek yogurt
• 1 tsp baking soda
• 1/2 tsp salt
• 1/2 tsp ground cinnamon
• 1 1/2 cups (190 g) all-purpose flour
• 1/2 cup chopped walnuts or chocolate chips (optional)

Instructions

1. Heat the oven to 350°F (175°C). Grease a 9x5-inch loaf pan and line it with a strip of parchment, leaving overhang on the long sides to lift the loaf out.
2. Mash. In a large bowl, mash the bananas with a fork. A few small lumps are fine.
3. Add wet ingredients. Stir in the melted butter, brown sugar, egg, vanilla and sour cream until combined.
4. Add leaveners. Sprinkle the baking soda, salt and cinnamon over the batter and stir well. Doing this before the flour helps them spread evenly.
5. Add flour. Add the flour and fold gently with a spatula just until no dry streaks remain. Fold in nuts or chocolate chips.
6. Bake. Pour into the pan and smooth the top. Bake 55 to 65 minutes, until a toothpick in the center comes out clean or with a few moist crumbs.
7. Tent if needed. If the top browns too fast after 40 minutes, lay a sheet of foil loosely on top.
8. Cool. Let it cool in the pan for 15 minutes, then lift it out onto a rack. Cool at least 30 minutes before slicing.

Tips for a moist loaf

Measure flour correctly. Too much flour is the most common cause of dry banana bread. Spoon flour into the cup and level it, or better, weigh it.

Don't overmix. Stir only until the flour disappears. Overmixing makes it tough and gives it tunnels.

Use brown sugar. It holds more moisture than white sugar and adds a light caramel flavor.

Sour cream or yogurt. A small amount makes the crumb extra tender. You can leave it out, but the loaf will be slightly less moist.

Is it done?

Banana bread is dense and takes a while to bake through. Oven temperatures vary, so start checking at 50 minutes. A toothpick should come out clean or with a few crumbs, not wet batter. If you have an instant-read thermometer, the center should read about 200°F.

A sunken middle usually means it was underbaked.

Variations

• Chocolate chip: add 3/4 cup chocolate chips. Sprinkle a few extra on top before baking.
• Cinnamon swirl: mix 2 tbsp sugar with 1 tsp cinnamon. Layer half the batter, sprinkle the mix, add the rest of the batter, and swirl with a knife.
• Muffins: divide into a 12-cup muffin tin and bake 18 to 22 minutes.
• Healthier: replace half the butter with unsweetened applesauce, and swap half the flour for whole wheat.

Storage

• Room temperature: wrap in foil or store in an airtight container for up to 4 days. It actually gets moister on day two.
• Fridge: up to a week, though it can dry out slightly.
• Freezer: wrap the whole loaf or individual slices in plastic wrap, then foil. Freeze up to 3 months. Thaw at room temperature or toast a slice from frozen.
