Method
Prep and mash
- Preheat the oven to 350°F and grease a 9x5 loaf pan.
- Mash the bananas, then whisk in the melted butter, brown sugar, eggs, vanilla, and dissolved espresso until smooth.
Mix dry and combine
- Sift together the all-purpose flour, cocoa powder, baking soda, and salt.
- Fold the dry mixture into the banana mixture until just combined, stopping as soon as no dry streaks remain.
Add chips and bake
- Fold in 3/4 cup of the dark chocolate chips and pour the batter into the loaf pan.
- Scatter the remaining chocolate chips over the top of the batter.
- Bake for 55–65 minutes at 350°F, until a toothpick inserted in the center comes out with just a few moist crumbs.
Cool and slice
- Cool the loaf in the pan for 15 minutes before turning it out.
- Slice only once fully cooled so the interior stays fudgy.
Notes
Pro tip: Stop mixing the moment the flour disappears to keep the loaf moist and tender. Store tightly wrapped at room temperature for up to 3 days or refrigerate for up to 5 days; freeze sliced loaf for up to 2 months. For a dietary swap, use a plant-based butter substitute and plant-based eggs if desired—texture may be slightly softer but still works well for a chocolate chip banana loaf.
