Moist Greek Yogurt Banana Bread is what I bake when the bananas on the counter have gone heavily speckled and soft. The yogurt gives the loaf a gentle tang and a plush crumb without making it taste like yogurt.
This version is simple enough for a weekday morning. You need one bowl for the wet ingredients, one for the dry, and no mixer. The loaf smells deeply banana-rich as it bakes, with a little warmth from cinnamon and a nutty top from chopped walnuts.
Moist Greek Yogurt Banana Bread Basics
The ingredient list is short, so ripe bananas and plain Greek yogurt matter most. Use bananas that look almost too soft to eat and a thick yogurt with no added flavor.
Walnuts add a little crunch, but the loaf is still good without them. If you measure flour by volume, spoon it into the cup and level it so the bread does not turn dense.
- Very ripe bananas. They bring the main sweetness, moisture, and deep banana flavor.
- Plain Greek yogurt. Adds tenderness and a mild tang that balances the sugar.
- All-purpose flour. Gives the loaf structure without making it heavy when measured lightly.
- Brown sugar. Keeps the crumb soft and adds a warm caramel note.
- Eggs. Help the loaf rise and slice cleanly once cooled.
- Neutral oil. Keeps the bread moist longer than melted butter.
- Vanilla and cinnamon. Round out the banana flavor without covering it up.
- Walnuts. Add crunch and a toasted flavor on top and through the loaf.
Mix it without overworking
- Prepare the pan. Heat the oven to 350 degrees F and line a 9x5-inch loaf pan with parchment so the bread lifts out cleanly.
- Mash the bananas. Mash them until mostly smooth, leaving a few small lumps for texture. Measure about 1 1/2 cups.
- Whisk the wet mix. Stir the mashed bananas with Greek yogurt, eggs, oil, brown sugar, granulated sugar, and vanilla until blended.
- Add the dry ingredients. Whisk flour, baking soda, baking powder, salt, and cinnamon in another bowl, then fold them into the banana mixture just until no dry streaks remain.
- Fold and fill. Fold in most of the walnuts, scrape the batter into the pan, and scatter the rest over the top.
- Bake and cool. Bake until the center is set and a toothpick comes out with moist crumbs, about 55-65 minutes. Cool before slicing so the crumb settles.
The moisture comes from balance
Greek yogurt helps this loaf stay soft because it brings both moisture and acidity. That acidity works with baking soda, which gives the bread a gentle lift. Oil helps too. Butter tastes great, but oil keeps quick breads softer after they sit overnight.
The other key is banana volume. I use 1 1/2 cups mashed banana instead of counting bananas by number, since banana size changes a lot. Too little banana makes the loaf dry. Too much can leave a gummy line near the bottom.
If you like banana bakes, this loaf sits nicely beside 3 Ingredient Banana Bread for a shortcut version and Brown Butter Sugar Cookie Banana Bread when you want something sweeter.
Do not rush the bake
Banana bread can look done before the center is ready. The top should be deeply golden, the middle should spring back, and the tester should show moist crumbs. Wet batter on the toothpick means it needs more time.
If the top browns too quickly, tent the pan loosely with foil for the last 15 minutes. Do not seal it tightly. You still want steam to escape so the loaf does not collapse.
For more reliable baking, weigh the flour if you have a scale. The King Arthur Baking ingredient weight chart is a useful reference when converting cups to grams.
Easy swaps and add-ins
Whole-milk Greek yogurt gives the richest crumb, but 2 percent or nonfat Greek yogurt also works. Sour cream can stand in for the yogurt if that is what you have. The flavor will be a touch richer and less tangy.
For add-ins, keep it to about 3/4 cup total. Chocolate chips make it dessert-like. Pecans are warmer and softer than walnuts. Blueberries work, but pat them dry first and expect a little extra moisture around the berries.

Storage that keeps slices tender
Let the bread cool completely before wrapping it. Warm banana bread traps steam, which makes the outside sticky and can soften the crust too much. Once cool, wrap the loaf or slices tightly.
At room temperature, it stays good for about 2 days. In the fridge, it keeps for about 5 days. I like to warm slices for 10 seconds in the microwave or toast them lightly and add a small swipe of butter.
To freeze, wrap individual slices and tuck them into a freezer bag. They thaw quickly on the counter and taste close to fresh after a brief warm-up.
Summary
Use very ripe bananas, plain Greek yogurt, and a light hand with the batter for banana bread that bakes up soft, moist, and easy to slice.
FAQs
- Can I use regular yogurt instead of Greek yogurt?
Yes, but the batter will be a little looser because regular yogurt has more water. Use plain whole-milk yogurt if you can. If it looks very runny, strain it through a coffee filter for 20 minutes first.
- How ripe should the bananas be?
The best bananas are deeply speckled or mostly brown. They should mash easily with a fork and smell sweet. Yellow bananas with only a few spots will make a firmer loaf with less banana flavor.
- Can I make this banana bread without walnuts?
Yes. Leave them out with no other changes, or replace them with chocolate chips, pecans, or blueberries. If you use berries, fold them in gently so the batter does not turn streaky and wet.
- Why did my banana bread sink in the middle?
It was probably underbaked or the batter was mixed too hard. Bake until the center springs back lightly and a toothpick comes out with a few moist crumbs, not wet batter. Let the loaf cool in the pan for 15 minutes before moving it.
- How do I store Greek yogurt banana bread?
Cool the loaf completely, then wrap it tightly and keep it at room temperature for 2 days or in the fridge for up to 5 days. For longer storage, freeze slices with parchment between them so you can thaw one at a time.
- Can I bake this as muffins?
Yes. Divide the batter into a lined muffin tin and bake at 350 degrees F for about 18-22 minutes. Start checking early because muffins dry out faster than a loaf.
