Method
Prep and combine wet ingredients
- Preheat the oven to 350°F and grease a 9x5-inch loaf pan.
- Mash the ripe bananas until smooth, then whisk with melted butter, sugar, eggs, and vanilla until the batter looks glossy and uniform.
Mix dry ingredients and fold
- Whisk the all-purpose flour, cocoa powder, instant espresso powder, baking soda, and salt in a separate bowl until evenly combined and no dry streaks remain.
- Fold the dry ingredients into the wet ingredients just until no flour pockets remain—do not overmix.
- Fold in the chocolate chips until they’re evenly distributed through the batter.
Bake and cool
- Pour the batter into the prepared loaf pan and smooth the top so it bakes evenly.
- Bake for 55–60 minutes at 350°F, until a toothpick inserted comes out with a few moist crumbs.
- Cool in the pan for 10 minutes before slicing so the loaf finishes setting.
Notes
For a bakery-style dome, smooth the top and avoid overmixing once the flour goes in—overmixing can make the loaf dense. Store airtight at room temperature up to 3 days or refrigerate up to 5 days. Freeze sliced bread up to 2 months. For a lower-sugar option, replace granulated sugar with an equal-measure baking sugar substitute that includes a sweetener and bulk (no need to adjust baking soda/baking time if it’s designed for baking).
