Banana bread is comforting on its own, but the addition of rich miso caramel sauce transforms this familiar favorite into something unforgettable. The sweet-savory depth of miso balances the natural sweetness of ripe bananas, creating a moist, deeply flavorful loaf that feels both nostalgic and sophisticated.
Preheat the oven to 350°. Grease an 8.5” x 4.5” loaf pan with butter or pan spray.
Place bananas in a microwave-safe bowl and cook them for 30 seconds until banana juices are released.
Mash and whisk the bananas until slightly chunky banana purée forms.
In a large bowl, whisk bananas, brown sugar, granulated sugar, butter, eggs, vanilla, and miso paste until smooth.
In a separate bowl, whisk flour, baking soda, salt, and nutmeg.
Fold dry ingredients into the wet until just combined.
Pour the mixture into the pan and smooth the top with a spatula. Layer sliced banana to the top of the mixture and sprinkle with a teaspoon of granulated sugar.
Place the banana bread into the oven and make the miso caramel while the bread bakes.
Heat sugar in the saucepan over medium heat, stirring until melted and amber in color. Carefully whisk in butter. It will start to bubble up, and this is completely normal. Slowly add lightly warmed cream, whisking the mixture until smooth.
Remove the saucepan from the heat and whisk in miso until fully incorporated.
Set aside miso caramel to cool slightly. If the mixture becomes too thick, a teaspoon of water or cream will help thin it out.
Bake the bread for 55 to 60 minutes, until a toothpick comes out clean or with a few moist crumbs.
Cool the bread for 15 to 20 minutes, then drizzle the miso caramel on top of the banana bread.
