This ultimate moist banana bread is super soft and flavorful — truly the best banana bread recipe. It’s easy to make in one bowl by hand and stays unbelievably moist for days. Say hello to your new favorite loaf.
The Secret To The Ultimate Moist Banana Bread
- Sour cream — adds richness and keeps the loaf tender and moist.
- Cornstarch — a little cornstarch improves texture and helps the bread stay soft.
- Melted butter — easy to use and contributes both flavor and moisture.
- Ripe, spotty bananas — the riper the bananas, the more banana flavor and natural sweetness.
These elements together turn a classic banana bread into something truly special. No dry loaves here.

How to Make the Best Banana Bread
Before you start: Preheat the oven
Preheat your oven to 350°F and give it at least 20 minutes to come fully up to temperature. A properly heated oven helps the loaf rise and bake evenly.
Step 1: Mash bananas
In a large bowl, mash 1½ cups ripe bananas (about 3 large) with a fork until smooth. Break up any large chunks so the bananas incorporate evenly into the batter.
Step 2: Add wet ingredients
- Stir in melted butter (½ cup), light brown sugar (½ cup), and granulated sugar (½ cup) until combined.
- Add eggs (2 large), sour cream (½ cup), and vanilla (2 teaspoons) and stir until just combined. Gently fold in baking soda (1 teaspoon), baking powder (½ teaspoon), and cinnamon (½ teaspoon).
Important: Mix by hand to avoid incorporating too much air — this keeps the bread dense and moist.
Step 3: Add dry ingredients
Gently fold in cornstarch (1 tablespoon), salt (½ teaspoon), and all-purpose flour (1½ cups) until just combined. Stop mixing as soon as the flour disappears — overmixing makes the loaf tough.
Step 4: Fill pan
Grease a 9″ metal loaf pan and fill it about two-thirds full. Because loaf pan sizes vary, you may have a bit of extra batter — bake extras in muffin tins for 18–20 minutes.
Step 5: Bake & let cool
Bake at 350°F for 60 minutes on the bottom or middle rack. After 45 minutes, gently tent the top with foil to prevent over-browning. Test doneness with a toothpick — it should come out clean or with a few crumbs.
Oven placement tip: Keep the loaf away from the top heating element so the top doesn’t brown faster than the interior cooks.
Step 6: Let cool, slice, and enjoy
Allow the loaf to cool in the pan for about an hour so it sets. Slice with a straight-edged knife into thick pieces to showcase the moist crumb. Spread butter on warm slices or enjoy at room temperature. This banana bread often tastes even better on day two once the flavors meld.
Storing, Freezing, and Gifting
How to store banana bread
To keep the loaf moist, wrap it while slightly warm (not hot) with a layer of paper towel and then plastic wrap; the towel absorbs excess surface moisture while the plastic traps internal moisture. Alternatively, use a gallon-sized zipper bag.
Can you freeze banana bread?
Yes. Wrap the loaf in several layers of plastic wrap and place it in a freezer bag or container for up to 3 months. Thaw at room temperature while still wrapped.
Ripe bananas are key
How to ripen bananas quickly
If you need ripe bananas fast, place unpeeled bananas on a rimmed baking sheet at 300°F for 30–40 minutes. The peels will darken and the insides will soften and caramelize, giving you perfect baking bananas.
How ripe should bananas be?
For the best flavor, use bananas that are heavily spotted, mostly brown, or even black. The riper they are, the more intense the banana flavor in the loaf. Organic bananas can have a stronger banana taste, if you prefer that.
More Frequently Asked Questions
If you don’t have sour cream, plain Greek yogurt works well. Stir the yogurt before measuring so excess liquid doesn’t affect the batter.
Using oil will change texture and flavor. Melted butter gives a richer taste and slightly different crumb, which I prefer.
No. Corn flour and cornstarch are different. If you don’t have cornstarch, you can omit it, though the bread may be slightly less tender.
Yes — a 1:1 gluten-free all-purpose flour blend can be used. Texture may differ slightly, but it works well for gluten-free diets; check ingredient labels for allergens.
Absolutely. Add ½ cup toasted walnuts or raisins for banana nut bread, or 1 cup semi-sweet chocolate chips for chocolate chip banana bread.
Yes. Fill greased muffin tins about ¾ full (≈4.5 tablespoons each) and bake 18–20 minutes until a toothpick comes out clean; yields about 12 muffins.
Melted butter, sour cream (or Greek yogurt), and cornstarch are key contributors to a tender, moist loaf.

Notes from Melissa
If you don’t have sour cream, use plain Greek yogurt. For muffins, fill tins ¾ full and bake 18–20 minutes. Store warm loaves wrapped in foil to cool, then plastic wrap or a zipper bag for longer storage. To freeze, wrap tightly and freeze up to 3 months. Thaw wrapped at room temperature. This bread often improves on day two.
