Serves:

1 loaf, about 9 slices

Ingredients

6 ounces bittersweet chocolate, chopped for melting

2/3 cup of chopped walnuts

1 1/2 cups all-purpose flour

3/4 teaspoon baking soda

1/4 teaspoon baking powder

1/4 teaspoon ground cinnamon

Pinch ground cloves

1 teaspoon pure vanilla extract

3 cups ripe bananas, diced (about 4 bananas)

1/3 cup buttermilk, at room temperature

1/2 cup (1 stick) unsalted butter, softened

1 cup sugar

2 tablespoons vegetable oil

1 large egg, at room temperature

Directions

Position a rack in the center of the oven and preheat to

350 degrees F. Butter and flour a 9-by-5-by-3-inch loaf

pan.

Put the chocolate in a heatproof bowl. Bring a saucepan

filled with an inch or so of water to a very slow simmer;

set the bowl on the pan (without touching the water). Stir

occasionally until melted and smooth. Keep warm.

Whisk the flour, baking soda, baking powder, cinnamon, and

cloves in a medium bowl. Stir the vanilla and half the

bananas into the buttermilk.

Beat the butter and sugar in a large bowl, with an electric

mixer on medium-high speed until light and fluffy, about 4

minutes. While mixing, drizzle in the oil and beat until

incorporated. Beat in the egg.

While mixing slowly add the flour mixture to the butter in

3 additions, alternating with the buttermilk mixture in 2

parts, beginning and ending with the flour. (Scrape the

sides of the bowl between additions, if needed). Fold in

the remaining bananas. Gently swirl the melted chocolate

into the batter so that it has a marbled effect. Scoop the

batter into the prepared pan. Bake until a toothpick

inserted in the center comes out clean, about 50 minutes.

Cool in the pan on a rack before unmolding and slicing
