Method
Preparation
- Preheat the oven to 350°F (175°C). Grease a 9x5-inch loaf pan and line it with parchment.
- In a medium bowl, whisk together the flour, cocoa powder, baking soda, kosher salt, and espresso powder. Set aside.
- Toss the dark and semi-sweet chocolate chips with 1 tablespoon of flour to help them stay suspended in the batter. Shake off any excess flour.
- In a large bowl, whisk the olive oil with the brown sugar and granulated sugar until combined. Add the eggs one at a time, whisking after each addition. Stir in the vanilla.
- Fold the sour cream and mashed bananas into the wet mixture until incorporated.
- Pour the dry ingredients into the wet ingredients and gently fold with a spatula until just combined.
- Fold in the floured chocolate chips and scrape the batter into the prepared loaf pan. Sprinkle extra chocolate chips on top and place the sliced banana.
Baking
- Bake for 50 to 60 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Tent with foil if browning too quickly.
- Allow the loaf to cool in the pan for 10 minutes, then lift it out using the parchment and transfer to a wire rack to cool completely before slicing.

Notes
For dairy-free version, swap the sour cream for a soy or coconut yogurt and use dairy-free chocolate chips. Store wrapped tightly or in an airtight container; refrigerate for up to 1 week or freeze for up to 3 months.
