The Best Banana Bread with Brown Butter and Walnuts
Learn to bake the best banana bread with this tested recipe featuring nutty brown butter, dark brown sugar, and a signature crackled sugar crust for ultimate depth.
To bake the best banana bread, you have to lean into the ugly. I’m talking about bananas that have gone entirely black and soft—the kind that look like they belong in the bin, not the fruit bowl. These are the only ones capable of providing the intense sweetness and punchy aroma required to stand up to the rich, toasted notes of brown butter.
This moist banana bread avoids the gummy, pale texture of lesser loaves by utilizing dark brown sugar for moisture and a high-heat start to set the crust. Adding toasted walnuts provides a necessary textural contrast, while a generous dusting of granulated sugar over the top before baking creates a shatteringly crisp, crackled lid.
If you have been searching for the best banana bread recipe that actually tastes like real fruit rather than just a sweet sponge, this is it. It is dense without being heavy, fragrant without being perfumed, and arguably better on day two after the flavors have fully melded.
Ingredients
The Batter
- 1/2 cup (115g) unsalted butter
- 1 1/2 cups (approx. 375g) very ripe bananas, mashed (about 3-4 large)
- 3/4 cup (150g) dark brown sugar, packed
- 1 large egg, room temperature
- 1 1/2 teaspoons vanilla extract
- 1 1/2 cups (190g) all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon kosher salt
- 1/2 teaspoon ground cinnamon
- 1/2 cup (50g) walnuts, toasted and roughly chopped
The Topping
- 1 tablespoon granulated sugar
- 1/4 teaspoon ground cinnamon
Instructions
- 1
Preheat your oven to 350°F (175°C) and grease a 9x5 inch loaf pan, lining the bottom with parchment paper for easy removal.
- 2
Place the butter in a small saucepan over medium heat, swirling occasionally as it melts and foams, until the milk solids turn a deep amber brown and smell nutty; remove from heat immediately.
- 3
Mash the black-skinned bananas in a large mixing bowl until mostly smooth but with a few small lumps remaining.
- 4
Whisk the warm browned butter and dark brown sugar into the mashed bananas until the sugar is dissolved and the mixture is glossy.
- 5
Add the egg and vanilla extract, whisking vigorously until fully incorporated and the batter lightens slightly in color.
- 6
Sift the flour, baking soda, salt, and cinnamon directly over the wet ingredients, then fold gently with a spatula until just a few streaks of flour remain.
- 7
Fold in the toasted walnuts, taking care not to overmix, which can lead to a tough loaf.
- 8
Pour the batter into the prepared pan and smooth the top with a spatula.
- 9
Mix the topping sugar and cinnamon together in a small bowl and sprinkle evenly over the entire surface of the batter.
- 10
Bake for 55 to 65 minutes, or until a skewer inserted into the center comes out clean or with just a few moist crumbs.
- 11
Cool in the pan for 15 minutes before transferring to a wire rack to cool completely.
Tips
- → Do not use yellow bananas. If they aren't covered in dark spots, the starch hasn't converted to sugar, and your bread will lack flavor.
- → Toast your walnuts in a dry pan for 3-5 minutes before adding them to the batter; it significantly improves the depth of the loaf.
- → If the top of the bread is browning too quickly due to the sugar crust, tent the pan loosely with foil after 40 minutes.
- → Always weigh your flour. Scooping with a measuring cup often packs the flour down, leading to a dry, dense bread.
FAQ
Why does my banana bread stay raw in the middle?
This usually happens if your oven temperature is too high, causing the outside to set before the middle cooks, or if you used too many bananas. Ensure you measure exactly 1.5 cups of mashed fruit.
How do I make my banana bread more moist?
Using dark brown sugar instead of white sugar adds molasses, which retains moisture. Additionally, browning the butter adds fat solids that keep the crumb tender for days.
Can I freeze this banana bread?
Yes. Wrap the cooled loaf tightly in plastic wrap, then aluminum foil. It will stay fresh in the freezer for up to 3 months.
