From the MyKitchenBank Kitchen

A sophisticated quick bread that layers miso paste's salty-savory character with buttery caramel and tender banana crumb. The miso heightens the banana's natural sweetness and adds an intriguing depth that keeps you reaching for another slice. Golden and aromatic from the oven, this loaf is tender, moist, and far more interesting than standard banana bread.

Steps

Before you start

Preheat oven to 350°F (175°C) and position a rack in the center
Grease a 9×5-inch (23×13 cm) loaf pan and line the bottom with parchment paper for easy release
Use ripe bananas with brown spots on the skin—they should be soft and smell fragrant
Measure all ingredients before you begin; once mixing starts, work quickly

1
Make the miso caramel
- In a medium saucepan, combine 0.5 cup (100 g) granulated white sugar, 3 tablespoons (45 g) unsalted butter, and 2 tablespoons (30 ml) water.
- Set the pan over medium heat and stir gently until the sugar dissolves.
- Stop stirring once it begins to boil (about 3 minutes); swirling the pan is fine if needed to ensure even cooking.
- Let the mixture cook undisturbed for 5–7 minutes until it reaches a deep amber color with a rich aroma.
- You should see it turn from golden to a copper-bronze shade.
- Remove from heat immediately.
- Stir in 0.25 teaspoon (1.5 g) sea salt.
- Let it cool for 1 minute, then slowly add 0.25 cup (60 ml) room-temperature heavy cream—it will bubble vigorously.
- Whisk until smooth.
- Stir in 2.5 tablespoons (45 g) white or chickpea miso paste until fully incorporated.
- The mixture will be smooth and glossy.
- Set aside to cool to room temperature, about 5–10 minutes.

Ready when: Caramel reaches deep amber color and miso is fully blended into the cream
Tip: Do not stir the caramel once it boils—stirring causes crystallization. Watch it closely at the end; it goes from perfect to burnt quickly. Add cream slowly to avoid splatters.
2
Prepare the dry ingredients
- In a large mixing bowl, whisk together 1.75 cups (220 g) all-purpose flour, 0.5 teaspoon (2.5 g) baking soda, 0.5 teaspoon (2.5 g) baking powder, and 0.25 teaspoon (1.5 g) kosher salt.
- Set aside.

Ready when: Dry ingredients are evenly combined with no lumps
3
Combine wet ingredients
- In a separate small bowl, whisk together 3 ripe medium bananas (about 400 g), mashed until mostly smooth with a few small lumps remaining, 2 large room-temperature eggs (beaten), 1 teaspoon (5 ml) vanilla extract, and the cooled miso caramel.
- Whisk until well blended and no streaks of egg remain.

Ready when: Mixture is smooth and uniform in color with no visible egg streaks
Tip: Leave banana lumps—they add texture. If eggs are cold, the batter will be lumpy. Room temperature eggs incorporate smoothly.
4
Fold wet and dry together
- Pour the wet ingredients into the bowl with dry ingredients.
- Using a rubber spatula, gently fold the two together just until combined—do not overmix.
- A few dry streaks are better than overworked batter, which makes the bread tough.
- The batter should be thick and chunky.

Ready when: No flour streaks visible and mixture is just combined
Tip: Overmixing develops gluten, which toughens quick breads. Stop folding as soon as you cannot see dry flour.
5
Fill the pan and bakeOven 350°F / 175°C
- Pour the batter into the prepared 9×5-inch (23×13 cm) loaf pan.
- If using flour for dusting, lightly sprinkle 1 tablespoon (8 g) all-purpose flour over the top—this helps browning.
- Place on the center oven rack and bake at 350°F (175°C) for 50–55 minutes.
- The loaf is done when a toothpick or skewer inserted into the center comes out with just a few moist crumbs (not wet batter).
- The top should be deep golden brown.
- The loaf will rise slightly above the edges of the pan.

Ready when: Toothpick inserted in center comes out with just a few moist crumbs; top is deep golden brown
Tip: Do not open the oven door until at least 40 minutes have passed. If the top browns too quickly, loosely tent with foil for the last 10–15 minutes.
6
Cool in pan, then remove
- Let the loaf rest in the pan for 10 minutes.
- This allows the crumb to set so it won't fall apart when turned out.
- Run a thin knife around the edges to loosen it from the pan.
- Invert the loaf onto a wire cooling rack and peel away the parchment paper.
- Cool completely on the rack for at least 2 hours before slicing.
- The loaf will firm up further as it cools.

Ready when: Loaf has cooled to room temperature and no longer steams when touched
Tip: Trying to slice a warm loaf will compress the crumb. If you must eat it warm, wait at least 1 hour and use a serrated knife with a gentle sawing motion.

Tips

White or chickpea miso paste is milder and works beautifully with sweet ingredients; red miso is deeper but saltier. Try white or chickpea first if you are new to miso in desserts.
The miso caramel is the star—let it cool completely before mixing into the batter so the eggs don't scramble from residual heat, and so the miso's flavor remains distinct rather than mellowing.
For extra richness, serve each slice slightly warm with a dollop of whipped cream or a drizzle of extra miso caramel on top.
Toast 0.5 cup (60 g) chopped walnuts or pecans and fold into the batter just before pouring into the pan for added texture and nutty contrast to the miso and caramel.

Make ahead

You can prepare the miso caramel up to 2 days ahead and store it in an airtight container in the refrigerator. Let it come to room temperature before folding into the wet ingredients. The fully baked loaf keeps for 2 days at room temperature before slicing.

Storage & reheating

Room temperature (airtight container or wrapped in plastic wrap): 2 days. Refrigerator (wrapped well): 5 days. Freezer (sliced, in a freezer bag): up to 3 months. Thaw slices at room temperature for 1–2 hours or warm in a 300°F (150°C) oven for 10 minutes.

Substitutions

white or chickpea miso paste → Red miso paste. Red miso is earthier and slightly saltier. Use the same amount but taste the caramel after adding it; you may reduce other salt by a pinch if it tastes very salty.
heavy cream (or heavy whipping cream) → Whole milk or oat milk. Use the same volume. The caramel will be slightly thinner, so chill it for 5 minutes after adding the miso to thicken it slightly before folding into batter.
all-purpose flour → Whole wheat flour or spelt flour. Replace up to half the all-purpose flour with whole grain flour. The loaf will be denser and nuttier but still moist. Add 1 tablespoon extra liquid (water or milk) if the batter looks very stiff.
ripe bananas → Overripe plantains or frozen-then-thawed bananas. Plantains are starchy; mash well and reduce amount slightly to 2.5 large. Frozen bananas release more liquid; drain excess before mashing.
