I baked a one-bowl banana bread so insanely moist and nutty from ripe bananas and walnuts that it melts in your mouth and leaves you wondering how that’s even possible.

Jump to Recipe

I am obsessed with this Ultimate Moist Banana Bread because it actually melts in your mouth and refuses to be boring. I love how the very ripe bananas sing through every forkful, sweet and slightly caramelized, cutting through the tender crumb.

I adore the crunch of chopped walnuts scattered inside and on top, little surprise pockets of nutty heat. Texture that makes me pause.

It’s simple but indulgent, the kind of loaf I steal slices from before anyone notices. And I’ll admit it: I judge other banana breads harshly now.

Worth breaking all my own rules for every single time.

Ingredient Quantities

1 1/2 cups all purpose flour

1 tsp baking soda

1/2 tsp baking powder

1/2 tsp salt

1/2 cup (1 stick) unsalted butter, melted and slightly cooled

3/4 cup packed light brown sugar

1/4 cup granulated sugar

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 350°F (175°C) and grease a 9×5-inch loaf pan or line it with parchment paper, leaving a bit of overhang to lift the bread out later.

2. In a large bowl whisk together 1 1/2 cups all purpose flour, 1 tsp baking soda, 1/2 tsp baking powder and 1/2 tsp salt; set aside.

3. Pour 1/2 cup melted unsalted butter into the flour bowl and stir briefly to moisten a little, then add 3/4 cup packed light brown sugar and 1/4 cup granulated sugar and mix until combined.

4. Crack in 2 large room temperature eggs, add 1 tsp vanilla extract and whisk or beat until smooth and slightly glossy; its okay if there are a few streaks.

5. Stir in 3 very ripe mashed bananas (about 1 1/2 cups) and 1/2 cup room temperature sour cream or plain yogurt until the batter is uniform. Don’t overmix, you want it just combined.

6. Fold in 1 cup chopped walnuts, reserving a handful to sprinkle on top. Use a spatula and be gentle so the bread stays tender.

7. Pour the batter into the prepared pan, smooth the top, and sprinkle the reserved walnuts over the batter.

8. Bake in the center of the oven for 50 to 65 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs but not wet batter. If the top browns too fast, tent loosely with foil after 30 to 40 minutes.

9. Let the loaf cool in the pan on a wire rack for 10 to 15 minutes, then lift it out using the parchment and finish cooling for at least another 30 minutes before slicing so it sets and stays moist.

10. Store wrapped at room temp for 2 days or in the fridge up to a week; you can warm slices briefly in the microwave or toaster oven. Freezes well for up to 3 months, just slice first so you can grab one quick.

Equipment Needed

1. Oven (preheated to 350°F / 175°C)
2. 9×5-inch loaf pan (or parchment paper to line it with a bit of overhang)
3. Large mixing bowl
4. Measuring cups and spoons
5. Whisk (or electric hand mixer if you prefer)
6. Rubber spatula for folding and scraping the bowl
7. Mixing spoon or wooden spoon
8. Wire cooling rack
9. Small knife or chopping board for the walnuts
10. Toothpick or cake tester to check doneness

FAQ

Q: Can I use frozen bananas or less-ripe bananas? A: Frozen bananas work great if thawed and drained a bit first; they get super sweet and mash easy. Less-ripe bananas will make the bread less flavorful and dense, so wait until they have lots of brown spots or a totally brown peel.

Q: Can I swap sour cream for yogurt or milk? A: Yes, plain yogurt is an equal swap and keeps the bread moist. Milk will thin the batter and make it less tender, so only use milk in a pinch and maybe add a tablespoon of melted butter or oil.

Q: How do I make the bread extra moist and not gummy? A: Use room temperature eggs and don’t overmix once you add the flour. Overmixing makes gluten tight and gives a gummy texture. Also measure flour by spooning it into the cup and leveling, not scooping with the cup.

Q: Can I make this nut-free or add chocolate chips? A: Yes to both. Omit the walnuts to make it nut-free and add 3/4 to 1 cup chocolate chips or chopped fruit instead. If you skip nuts, you might want to sprinkle a few extra chips on top for texture.

Q: What’s the best oven temp and baking time? A: Bake at 350°F for 55 to 65 minutes in a standard 9×5 loaf pan. Start checking at 50 minutes; a toothpick should come out with a few moist crumbs, not wet batter. If the top browns too fast, tent with foil.

Q: How do I store or freeze leftovers? A: Cool completely, then wrap tightly in plastic wrap and store at room temp for 2 days or in the fridge for up to 5 days. For longer storage, slice and freeze in a single layer on a tray, then bag the slices for up to 3 months. Thaw at room temp or toast gently.

Ultimate Moist Banana Bread Recipe Substitutions and Variations

All purpose flour: swap for whole wheat pastry flour 1:1 for a nuttier, slightly denser loaf; if you need gluten free use a 1:1 cup for cup gluten free blend and add 1/4 tsp xanthan gum if your blend has none.
Unsalted butter (melted): use neutral oil (canola, vegetable) 1:1 by volume, or melted coconut oil 1:1 if you want a hint of coconut. both keep the bread very moist, just don’t use flavored olive oil.
2 large eggs: replace each egg with 1 tablespoon ground flax mixed with 3 tablespoons water, let sit 5 minutes until gelled. good vegan swap but texture is a touch more dense.
1/2 cup sour cream: plain Greek yogurt works exactly the same 1:1 and gives the same tang and moisture; you can also use buttermilk 1:1 but reduce other liquid very slightly if your batter seems loose.

Pro Tips

1) Use really ripe bananas, like lots of brown spots or mostly black. They mash easier and give more banana flavor, so don’t try to “save” slightly green ones. If they’re too ripe to handle, freeze them peeled and thaw before mashing.

2) Get your eggs and sour cream to room temp. Cold ingredients can make the batter seize and give a denser loaf. If you forget, put the eggs in a bowl of warm water for 5 to 10 minutes instead of microwaving.

3) Don’t overmix once you add the flour. Stir until you just can’t see dry streaks. Overworking the gluten makes the bread tough; a few small lumps are fine and will bake out.

4) Watch the top in the last 15 minutes. If it’s browning too fast but the center isn’t set, loosely tent with foil and keep baking. Let it cool mostly in the pan, then lift out with the parchment so it sets up and stays moist.
