1-First Steps: Prepping Your Ingredients: Start by preheating your oven to 350°F (175°C) and grease a loaf pan. In one bowl, mash 1 cup of ripe bananas until smooth. In another, whisk together the wet items like ½ cup light-tasting olive oil, ½ cup brown sugar, ½ cup granulated sugar, 2 eggs, 1 teaspoon vanilla extract, and ½ cup sour cream.

2-Mixing and Baking: Now, combine the dry ingredients: 1 cup all-purpose flour, ¼ cup cocoa powder, 1 teaspoon baking soda, ½ teaspoon kosher salt, and ½ teaspoon espresso powder. Gently fold the dry mix into the wet one until just combined. Add in the chocolate chips after dusting them with 1 tablespoon flour to keep them from sinking.

3-Mixing and Baking: Pour the batter into your prepared pan and top with extra chips or banana slices if you like. Bake for 55-65 minutes, or until a toothpick shows few crumbs. Let it cool in the pan for 20 minutes, then on a rack before slicing.
