Method
Mixing the Dry Ingredients
- Preheat your oven to 350°F (175°C) and grease a 9×5-inch loaf pan.
- In a medium bowl, whisk together all-purpose flour, cocoa powder, baking soda, kosher salt, and espresso powder. Ensure there are no lumps, and set aside.
Mixing the Wet Ingredients
- In a large mixing bowl, combine olive oil, brown sugar, and granulated sugar. Mix until well combined.
- Add in eggs, vanilla extract, and sour cream. Whisk until smooth.
- Fold in ripe mashed bananas until fully incorporated.
Combining Dry and Wet Ingredients
- Gently add the flour mixture to the wet ingredients. Stir until just combined—don’t overmix!
- Toss dark chocolate chips and semi-sweet chocolate chips in all-purpose flour and fold gently into the batter.
Assembling and Baking
- Pour the batter into the prepared loaf pan. Press banana slices gently into the top and sprinkle with granulated sugar.
- Bake in the preheated oven for 55-60 minutes. Check for doneness by inserting a toothpick in the center; it should come out clean or with a few moist crumbs.
Cooling
- Let the bread cool in the pan for 10-15 minutes before transferring it to a wire rack to cool completely.
- For extra chocolatey goodness, you can melt a bit of chocolate and drizzle it over the cooled bread.
Notes
Store tightly wrapped in plastic wrap or in an airtight container at room temperature for up to 3 days. For longer storage, freeze slices individually wrapped in plastic for up to 2 months.
