Ingredients
  

Dry Ingredients

  • 1 cup (127 grams) all-purpose flour
  • ½ cup (43 grams) Dutch-process cocoa powder
  • ½ cup (100 grams) light brown sugar lightly packed
  • ¼ cup (50 grams) granulated sugar
  • ¾ teaspoon baking soda
  • ½ teaspoon kosher salt

Wet Ingredients

  • 3 medium/large bananas mashed
  • ½ cup sour cream full-fat, at room temperature
  • 2 large eggs at room temperature
  • 3 Tablespoons unsalted butter melted and slightly cooled
  • 3 Tablespoons neutral oil avocado or canola
  • 1 teaspoon vanilla extract

Mix-Ins

  • ½ cup semi-sweet chocolate chips

Optional Topping

  • 1 oz. semi-sweetchocolate baking bar finely chopped
  • cup (28 grams) heavy cream

Instructions
 

  • Prepare the pan: Line a 9x5 loaf pan with a parchment paper sling and secure it with binder clips.
  • Mix the dry ingredients: In a medium bowl, whisk together the flour, cocoa powder, sugars, baking soda, and salt until well combined. Set aside.
  • Melt the butter: In a small bowl, microwave the butter for about 30 seconds, or until fully melted. Set aside.
  • Preheat the oven: Set your oven to 350°F (175°C) while you prepare the batter.
  • Mash the bananas: In a large bowl, mash the ripe bananas with a fork until smooth. Add the eggs, sour cream, oil, melted butter, and vanilla extract into the same bowl. Whisk everything together until fully incorporated.
  • Combine wet and dry ingredients: Add the dry ingredients to the wet mixture, folding gently with a rubber spatula until just combined. Then, fold in the chocolate chips.
  • Fill the pan: Pour the batter into the prepared loaf pan, spreading it evenly.
  • Bake: Place the pan in the oven and bake for 60 minutes, or until a toothpick inserted into the center comes out clean.
  • Cool and remove: Let the banana bread cool in the pan on wire rack to cool completely. Once completely cooled, use a butter knife to loosen the edges without parchment paper. Remove from the pan and slice. Enjoy!
  • Optional ganache topping: For the ganache, heat the heavy cream in a small microwave-safe bowl until warm (about 30 seconds). Add the finely chopped chocolate, making sure the warm cream covers it, and let it sit for 1 minute. Stir with a small spatula or spoon until smooth and glossy. Drizzle or pour the ganache over the cooled banana bread. Once the ganache sets, slice and enjoy!

Notes

Tips for Success 
  • Room Temperature Ingredients: Allow your cold ingredients to come to room temperature before mixing. This ensures a smooth batter and results in a moist, even crumb.
  • Parchment Paper: Secure the parchment paper to your loaf pan using binder clips. You can leave the clips on during baking, but I prefer removing them for quick breads, as the batter tends to rise significantly and could come in contact with the clips.
  • Pans: If you're using a high-quality, light aluminum loaf pan (like the USA brand I recommend), there’s no need to grease it.  
  • One-Bowl Banana Mashing: Mash the bananas directly in the large bowl used for the wet ingredients. It saves you from washing an extra bowl.
  • Mash the Bananas Well: Make sure to mash the bananas thoroughly – large chunks can affect the texture of the bread. It’s worth taking the extra time to get them completely smooth for a consistent crumb.
  • Don’t Overmix: Once the wet and dry ingredients are combined, be careful not to overmix. Gently fold the batter with a spatula until just combined. Overmixing can lead to a dense loaf.
