For best flavor, use very ripe bananas with plenty of brown spots, as they add natural sweetness and moisture to the loaf, and ensure your espresso is cooled so it doesn’t scramble the eggs or make the batter too loose. Avoid overmixing once the flour is added, which can make the bread dense rather than tender, and check doneness starting a few minutes early since ovens vary, tenting the loaf with foil if the top browns too quickly. You can adjust the intensity of the coffee flavor by using espresso powder (1–2 teaspoons dissolved in a tablespoon of hot water) instead of brewed espresso, and swap dark chocolate for milk or white chocolate if you prefer a sweeter result. This bread keeps well wrapped at room temperature for up to 3 days and tastes even richer the next day, and individual slices can be briefly toasted and served warm with a little butter for an extra treat.
