For the cake:

  • 1 1/ cups (12 oz.) unsalted butter
  • 2 ¾ cups unbleached all-purpose flour
  • 2 teaspoons baking powder
  • A pinch of salt
  • ½ teaspoon ground cinnamon
  • 1 ¾ cups mashed very ripe banana
  • 1 cup low-fat buttermilk, at room temperature
  • 4 tablespoons unsweetened cocoa powder
  • 2 cups packed light brown sugar
  • 4 large eggs room temperature
  • ¾ cup toasted pecans, chopped

For the ganache:

  • 5 tablespoons unsalted butter
  • 2 ¾ cups chopped the dark chocolate (70% cacao)
  • 1 ½ tablespoon powdered sugar
  • A pinch of salt
  • 2 cups heavy cream

For garnish (optional):

  • chocolate sprinkles
  • chocolate chips


To make the cake:

  • In a saucepan, apply the butter and cook over medium heat, stirring frequently, until melted and the bottom of the saucepan turn dark brown, around five minutes; scrape the browned butter into a small bowl. Place in the fridge for 1 hour to set softly.
  • In the meantime, position a rack in the middle of the oven and heat the oven to 180°C/350°F/Gas Mark 4. Then, grease three 9-in. round cake baking pans and line the bottoms with parchment, grease the parchment; set aside.
  • In a medium bowl, beat together the flour, cocoa powder, baking powder, cinnamon, and salt. In a separate bowl, mix together the buttermilk and mashed bananas.
  • Remove the browned butter from the fridge and apply in a large bowl, then apply the brown sugar; using an electric mixer, beat them together on medium speed until fluffy and light, about 3-4 minutes. Apply the eggs one at a time, whisking well after each addition.
  • Next, decrease the speed to slow and alternately apply the banana mixtures and flour in 3 additions each. Add the chopped pecans and combine with a spatula.
  • Then, divide the batter evenly between the prepared pans. Tap the pans to remove any air bubbles.
  • Place in the oven and bake the cakes, switching and rotating positions halfway through baking, until a toothpick inserted in the middles comes out clean, about 30-35 minutes.
  • Allow the cakes cool in the pans on racks for 15 minutes. Next, turn the cakes out onto the racks, take out the parchment, and let them cool completely.
  • In the meantime, prepare the dark chocolate ganache.

To make the ganache:

  • In a small saucepan, over medium heat, cook the butter until melted and browned, around five minutes. Remove the browned butter from the heat and transfer into a medium metal bowl. Apply the chocolate and salt.
  • In the same saucepan, pour the heavy cream and bring to a boil over medium heat; remove and immediately pour over the butter and chocolate. Let stand two minutes, and after that whisk until smooth.
  • Allow cooling at room temperature, until spreadable and thickened (stirring on every 15 minutes) for about 45 minutes.

To assemble the cake:

  • Arrange 1 cake layer on a cake plate and top with 3/4 cup chocolate ganache, smoothing with an offset spatula.
  • Next, apply the 2nd cake layer; spread with another 3/4 cup ganache. Arrange the 3rd cake layer and spread the remaining chocolate ganache over the top and side of the dessert.
  • Decorate with chocolate sprinkles and/or chocolate chips (if desired). Slice and serve.
