Banana bread is my reliable crowd-pleaser—perfect for a casual brunch or a midweek office pick-me-up. This version adds a subtle twist: white miso paste. You won’t taste overt miso, but its gentle umami enhances the natural sweetness of ripe bananas. A handful of dark chocolate chips creates a lovely contrast, making this Miso Banana Bread a steadfast favorite.
With kids who demand bananas at the most inconvenient times, I often end up making variations of banana bread. I usually start from my brown butter banana bread base and adapt from there.
This recipe is a chocolate chip banana bread infused with miso—a quick-bake take on my miso banana cake—ideal for an easy brunch, snack, or grab-and-go breakfast. No frosting, plates, or utensils required.
Trang’s Recipe Highlights
- FLAVOR: Sweet banana balanced with savory miso, finished with nutty brown butter and dark chocolate.
- TEXTURE: Moist, tender crumbs with pockets of chocolate and a caramelized, slightly crisp crust.
- EASE: Simple to make by hand with basic tools. Brown butter sounds fancy but is easy to master—just watch it and whisk when it foams.
Things you’ll need for chocolate chip banana bread with miso
This recipe uses ten ingredients (photos below). The full ingredient list with exact amounts and step-by-step instructions is available in the recipe card.
Frozen vs. fresh brown bananas
Both work as long as frozen bananas were at peak ripeness when frozen. I often freeze overripe bananas to save them. Thaw and mash frozen bananas including any liquid released during thawing—this keeps moisture and flavor.
Type of miso to use
I used a mild white miso with lower sodium so I could add a generous amount—about 3 tablespoons—for depth without saltiness. Check your miso’s nutrition label: if it has higher sodium, reduce the amount accordingly. Aim to keep total sodium from miso around 1000 mg for the whole loaf.
About the chocolate chips
I tested semisweet (around 51% cacao), bittersweet (60% cacao) and dark (72% cacao). Bittersweet struck the best balance for me: not too sweet, not too bitter. Choose chocolate between roughly 55% and 72% cacao depending on how sweet or bitter you prefer the final loaf.
Quick tips
Baking banana bread requires balancing moisture and doneness. This miso chocolate chip banana bread usually needs about 60–65 minutes at 350°F. Watch the crack on top: if it still looks like wet batter, it needs more time. When using a toothpick, test the center rather than the edge—the center finishes last.
When in doubt, a slightly underbaked loaf is preferable to one that’s overbaked and dry. Let it cool completely before slicing for cleaner slices, or serve slightly warm for a softer texture.

Miso Banana Bread Recipe

Comment
Equipment
-
Stainless steel saucepan
-
Loaf pan
Ingredients
- 4 oz unsalted butter (113 g), browned
- 1 1/3 cup mashed banana (320 g)
- 3 tablespoons white miso paste (50 g) — see note on sodium
- 2 large eggs, room temperature
- 1 teaspoon pure vanilla extract
- 3/4 cup packed brown sugar (150 g)
- 1 3/4 cup all-purpose flour (230 g)
- 1/2 teaspoon baking soda
- 1 teaspoon baking powder
- 1 cup chocolate chips (55–72% cacao, 169 g)
- Melted butter or baking spray for pan
Instructions
-
Brown butter: Place butter in a light-colored saucepan over medium heat. Once melted it will foam; when the foam subsides and clear bubbles form, whisk continuously to prevent burning. When the butter turns caramel-colored and smells nutty (about 8–9 minutes), remove from heat and cool.
-
Prepare wet ingredients: Mash bananas in a large bowl. Add miso, cooled brown butter, eggs, and vanilla. Whisk until combined.
-
Add sugar: Stir in the brown sugar and beat until fully incorporated.
-
Combine dry ingredients: Sift flour, baking soda, and baking powder into the wet mixture. Gently mix with a whisk or spatula until about three-quarters combined with some streaks of flour remaining.
-
Fold in chocolate: Add chocolate chips and fold gently to finish combining the batter and distribute the chocolate evenly.
-
Preheat the oven: Position the rack in the middle and preheat to 350°F (175°C) while the batter rests.
-
Prepare the pan: Brush a loaf pan with melted butter and line with a long strip of parchment, leaving overhang to use as handles. Brush the parchment with more melted butter.
-
Bake: Transfer batter to the prepared pan and bake about 60–65 minutes, until a toothpick inserted into the center comes out clean or with no wet batter attached.
-
Cool: Remove from oven and cool completely on a wire rack. Lift the loaf from the pan using the parchment overhang.
Notes
- Choose low-sodium miso: A milder white miso lets you add more for umami without excess salt. Adjust if your miso is saltier—aim for roughly 1000 mg total sodium from the miso in the loaf.
- Storage: Store in an airtight container at room temperature for 3–5 days, or freeze for 3–6 months.
- Reheating: Serve slightly warm: wrap a slice in plastic or cover with a damp paper towel and microwave 15–20 seconds. For frozen slices, heat in short bursts until warmed through.
