Preparation
- Preheat your oven to 350°F (175°C). Grease and flour a 9x5 inch loaf pan, or line it with parchment paper, leaving an overhang on the long sides for easy removal.
Combine Dry Ingredients
- In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, light brown sugar, unsweetened cocoa powder, baking soda, and salt until they are well combined and there are no visible lumps.
Combine Wet Ingredients
- In a separate medium mixing bowl, thoroughly mash the ripe bananas with a fork. Add the egg, melted and cooled butter, sour cream, vanilla extract, and cooled espresso. Whisk these wet ingredients until they are just combined.
Mix and Fold
- Pour the wet ingredients into the dry ingredients. Stir gently with a rubber spatula until just combined. Be careful not to overmix; a few lumps are perfectly fine. Overmixing can result in a tough banana bread.
- Gently fold in the semi-sweet chocolate chips until they are evenly distributed throughout the batter.
Bake
- Pour the batter into the prepared loaf pan and spread it evenly. Bake for 55-65 minutes, or until a wooden skewer or toothpick inserted into the center of the loaf comes out clean, or with only moist crumbs attached (no wet batter). If the top starts to brown too quickly, you can loosely tent it with aluminum foil during the last 15-20 minutes of baking.
Cool and Serve
- Let the banana bread cool in the pan on a wire rack for 10-15 minutes. Then, carefully lift it out of the pan (using the parchment paper overhang if applicable) and transfer it to the wire rack to cool completely. Cooling completely helps the bread set properly and prevents it from crumbling when sliced.
Notes
For an extra touch, you can sprinkle an additional tablespoon of chocolate chips or a light dusting of cocoa powder on top of the batter before baking. Ensure your bananas are very ripe (with plenty of brown spots) for the best natural sweetness and banana flavor. Store leftover chocolate espresso banana bread tightly wrapped at room temperature for up to 3 days, or in the refrigerator for up to a week. It also freezes well for up to 3 months; wrap tightly in plastic wrap and then in foil.
