This black walnut banana bread takes the friendship between walnuts and quick breads up a notch by including the nuts in the batter and in the buttery streusel topping. Because it's not just enough to sprinkle walnuts on top—for it to really be the best possible slice, the flavor of walnuts should be in every bite. A buttery, crunchy streusel provides textural contrast to the moist bread. The simple buttermilk glaze offers a little sweet tang.

Ingredients

Streusel:

  • 1/4 cup all-purpose flour

  • 1/4 cup packed light brown sugar

  • 1/4 tsp. kosher salt

  • 1/4 tsp. ground cinnamon

  • 3 Tbsp. unsalted butter, softened

  • 1/4 cup toasted chopped black walnuts

Bread:

  • 2 cups all-purpose flour

  • 1 tsp. baking soda

  • 1 tsp. ground cinnamon

  • 3/4 tsp. kosher salt

  • 3 medium bananas

  • 2 large eggs

  • 2/3 cup granulated sugar

  • 1/2 cup canola or vegetable oil

  • 1/3 cup packed light brown sugar

  • 1/3 cup whole buttermilk

  • 2 tsp. vanilla extract

  • 1/2 cup toasted chopped black walnuts

Glaze:

  • 1/2 cup powdered sugar

  • 1 Tbsp. whole buttermilk

  • 1/4 tsp. vanilla extract

Directions

  1. Preheat oven to 350°F. Line bottom and sides of a 9- x 5-inch loaf pan with parchment paper, leaving a 1-inch overhang on all sides; set aside.

  2. Prepare the Streusel: Whisk together flour, brown sugar, salt, and cinnamon in a medium bowl. Add softened butter, and stir together until crumbly; stir in walnuts until evenly distributed. Set aside.

  3. Prepare the Bread: Whisk together flour, baking soda, cinnamon, and salt in a large bowl; set aside. Place bananas in a medium bowl; mash with a fork until almost smooth. Add eggs, granulated sugar, oil, brown sugar, buttermilk, and vanilla extract; whisk until smooth. Add banana mixture to flour mixture; stir until well combined. Stir in walnuts until evenly distributed.

  4. Pour batter into prepared loaf pan, smoothing into an even layer with a spatula; sprinkle evenly with Streusel. Bake in preheated oven until a wooden pick inserted in center comes out with a few moist crumbs, 1 hour to 1 hour, 5 minutes. Let cool in pan on a wire rack 10 minutes; remove from pan. Let cool on wire rack 1 hour.

  5. Prepare the Glaze: Whisk together powdered sugar, buttermilk, and vanilla in a small bowl until smooth. Drizzle over cooled Bread. Slice and serve.
