Easy Moist Banana Bread Recipe From Scratch

I make this banana bread recipe at least twice a month. It bakes up tender and moist every time, with a golden cracked crust and deep banana flavor. Sour cream and brown sugar are the two ingredients that set this loaf apart from every other version I’ve tried.

Why This Banana Bread Recipe Works

The key is using very ripe bananas — the blacker the peel, the sweeter and more intense the flavor. I wait until the peels are almost entirely black before I bake. Underripe bananas taste starchy and flat in a finished loaf.

Brown sugar adds moisture that white sugar cannot match. It gives the bread a subtle caramel depth that pairs with the cinnamon and vanilla. I’ve made this banana bread recipe both ways, and brown sugar wins every time.

Sour cream is the ingredient most recipes skip. It makes the crumb tender and tight without thinning the batter. I use 1/4 cup, and it keeps the loaf soft for three full days at room temperature.

The method matters too. I melt the butter instead of creaming it, which gives a denser, more fudgy crumb. Overmixing once the flour goes in makes the loaf tough — stir until just combined and stop.

Ingredients

• 3 very ripe bananas (about 1 1/2 cups mashed)
• 2 cups all-purpose flour
• 1 teaspoon baking soda
• 1/4 teaspoon salt
• 1 teaspoon ground cinnamon
• 3/4 cup packed light brown sugar
• 1/2 cup (1 stick) unsalted butter, melted and cooled
• 2 large eggs, beaten
• 1/4 cup sour cream
• 1 teaspoon vanilla extract

What You Need for Banana Bread Recipe

Very ripe bananas — The riper the better. Black-peeled bananas are sweetest and mash smoothly. You need about 1 1/2 cups mashed, which is 3 medium bananas. Underripe yellow bananas produce a starchy, less sweet loaf.

All-purpose flour — Standard all-purpose works perfectly for this banana bread recipe. Bread flour makes the crumb too dense and chewy. I haven’t tested it with almond or oat flour in this exact ratio.

Baking soda — This is the leavener. It reacts with the natural acids in banana and sour cream to give the loaf its rise. Baking powder is not a direct substitute — stick with baking soda.

Salt — Just 1/4 teaspoon sharpens every other flavor in the loaf. Don’t skip it, even though it seems like a small amount.

Ground cinnamon — I love the warmth it adds to banana bread. Swap it for ground cardamom if you want something slightly floral and different from the classic version.

Light brown sugar — Dark brown sugar works too and gives a stronger molasses flavor. I use light for a more balanced sweetness that doesn’t compete with the banana.

Unsalted butter, melted — Melted butter gives a tender, fudgy crumb. Use unsalted so you control the salt. Melted coconut oil works as a substitute at the same ratio.

Eggs — Two large eggs bind the batter and add structure. Room-temperature eggs mix into the batter more evenly than cold eggs straight from the fridge.

Sour cream — My moisture secret. Full-fat Greek yogurt works as a 1:1 swap if that’s what you have on hand. Both add tang and tenderness to the crumb.

Vanilla extract — Pure vanilla extract adds rounded warmth. Imitation vanilla works but the flavor is thinner. Use pure if you have it for the best result.

How to Make Banana Bread Recipe

1. Preheat oven to 350°F (175°C). Grease a 9×5-inch loaf pan with butter or nonstick spray.
2. Mash the ripe bananas in a large bowl until mostly smooth, with a few small lumps remaining.
3. Whisk in the melted butter, brown sugar, eggs, sour cream, and vanilla until fully combined.
4. In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon.
5. Add the dry ingredients to the wet ingredients. Stir until just combined — do not overmix.
6. Pour the batter into the prepared loaf pan and smooth the top with a spatula.
7. Bake for 58 to 62 minutes, until a toothpick inserted in the center comes out clean.
8. Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.

Banana Bread Recipe Variations

Chocolate Chip Banana Bread

Fold 1 cup of semi-sweet chocolate chips into the batter just before pouring it into the pan. The chips melt into pockets throughout the loaf. I use mini chips so they distribute more evenly through every slice.

Walnut Banana Bread

Add 3/4 cup of roughly chopped walnuts to the batter before baking. The toasted, slightly bitter nuts balance the sweet banana beautifully. Toast the walnuts in a dry skillet for 3 minutes first — it deepens their flavor significantly.

Cinnamon Swirl Banana Bread

Mix 2 tablespoons brown sugar and 1 teaspoon cinnamon in a small bowl. Pour half the batter into the pan, sprinkle the cinnamon sugar over it, then top with remaining batter. Run a knife through once to create a swirl.

Banana Bread Muffins

Use this same banana bread recipe to make 12 to 15 muffins. Fill lined muffin cups 3/4 full. Bake at 350°F for 21 to 23 minutes, until a toothpick comes out clean. They freeze individually and thaw in 10 minutes.

Tips for the Best Banana Bread

• I always wait until the bananas are completely black-peeled — it makes the biggest difference in flavor.
• Don’t overmix once the dry ingredients go in. Stir until just combined for a tender, soft crumb.
• Tent the loaf loosely with foil at the 45-minute mark if the top is browning too quickly.
• Let the loaf cool fully before slicing — cutting too early makes the center gummy and dense.
• Room-temperature eggs and sour cream blend into the batter more smoothly than cold ones.
• A 9×5-inch pan gives a taller loaf. An 8.5×4.5-inch pan produces a slightly shorter, wider result.

Make Ahead & Storage

This banana bread recipe keeps at room temperature for up to four days wrapped tightly in plastic wrap or stored in an airtight container. I place a sheet of paper towel underneath to absorb any extra moisture from the bottom.

To freeze, wrap individual slices in plastic wrap and seal in a freezer bag. Frozen slices keep for three months and thaw on the counter in about 20 minutes. I freeze half the loaf every time I bake — it means fresh banana bread is always 20 minutes away.

Common Questions

Why is my banana bread gummy in the middle?

The most common cause is underbaking. Ovens run at different temperatures, so the timer alone is unreliable. Insert a toothpick into the thickest part of the center — it should come out clean or with a dry crumb, not wet batter.

Can I use frozen bananas for banana bread?

Yes, frozen bananas work well for this banana bread recipe. Thaw them at room temperature and drain any excess liquid before mashing. They tend to be softer and sweeter than fresh bananas and mash more easily.

Do I need sour cream for this recipe?

Sour cream adds moisture and helps with the tender crumb. If you don’t have it, substitute equal amounts of full-fat Greek yogurt. The texture and flavor stay very close. I’ve made this banana bread recipe both ways successfully.

How ripe do bananas need to be for banana bread?

The riper the better. The peels should be mostly brown to fully black. At that point the bananas are sweetest and mash smoothly. Yellow bananas produce a starchier, less flavorful loaf that won’t taste as rich.

Can I make banana bread without eggs?

Yes. Replace each egg with a flax egg: 1 tablespoon ground flaxseed mixed with 3 tablespoons water, rested for 5 minutes until gel-like. The loaf is slightly denser but holds together well and still tastes great.
