Step 1

Preheat your oven to 350°F (175°C) and line an 8x4-inch loaf pan with parchment paper.

Step 2

Whisk together the dry ingredients. Add the flour, sugar, cocoa powder, baking soda, baking powder, and salt to a mixing bowl. Whisk until combined.

Step 3

Melt the chocolate. Over a double-boiler, melt the dark chocolate chips or chocolate chunks. To make a double boiler: place a sauce pan on the stove and fill it with about ½ cup of water. Next, place an aluminum or heat-proof glass bowl on top of the saucepan. The bowl should not touch the water and just sit on the edges of the saucepan. Finally, heat the water to a simmer over low-medium heat.

Step 4

Mash the bananas. While the chocolate is melting, add the bananas to a blender and blend until smooth. Alternatively, you can mash the bananas in a bowl with a fork.

Step 5

Combine. Pour the mashed bananas, oil, and melted chocolate over the dry ingredients and mix using a wooden spoon until combined. Stop mixing as soon as everything is incorporated.

Step 6

Transfer the batter. Pour the batter into the prepared loaf ban and spread it into an even layer. At this point, you can top it with dark chocolate chips if using.

Step 7

Bake. Finally, bake the bread for about 45 minutes. You can test the doneness by pricking the banana bread with a toothpick. If it comes out with a few crumbs, it's done.
