Ingredients

For the Banana Bread:

  • 105 g all-purpose flour
  • 45 g graham cracker crumbs (approx. 3 full-sheet graham crackers)
  • ¾ teaspoon baking soda
  • ¼ teaspoon fine sea salt
  • 85 g unsalted butter melted
  • 100 g granulated sugar
  • 45 g sour cream room temperature
  • 1 teaspoon vanilla bean paste
  • 1 large egg (~50 g)
  • 25 g applesauce
  • 113 g 70% cacao dark chocolate chopped
  • 227 g mashed bananas (approx. 2 medium ripe bananas)

For the Topping:

  • 28 g 70% cacao dark chocolate divided
  • 36 g mini marshmallows
  • graham crackers
Makes: 8 x 4inch rectangle

Instructions

  • Preheat the oven to 350°F (180°C). Line an 8x4-inch loaf pan with parchment paper, letting the excess hang over the long sides to form a sling. Spray the inside with cooking spray and then set aside.
  • In a large bowl, whisk together the flour, graham cracker crumbs, baking soda, and salt then set aside.
  • In a medium bowl, whisk together the melted butter, sugar, sour cream, vanilla, egg, and applesauce until combined. Add the wet ingredients to the dry ingredients and stir until just combined. Then add the mashed banana and stir until incorporated.
  • Fold in the chocolate chunks until just incorporated. Pour the batter into the prepared loaf pan, and bake until deeply golden brown and a toothpick inserted into the center of the loaf comes out clean, about 50-60 minutes. Let cool at least 10 minutes, then transfer the loaf to a baking sheet.
  • Preheat the oven to broil and melt half of the chocolate for the topping. Drizzle the top of the loaf with melted chocolate and cover with marshmallows. Top with the remaining chocolate bar pieces and graham crackers. Broil for 1-2 minutes.
