Double Chocolate Banana Bread is a delightful treat that combines the rich flavors of chocolate with the natural sweetness of ripe bananas. Perfect for any time of year, the recipe creates a moist and decadent loaf that is sure to please everyone. Whether enjoyed as a snack or a dessert, it’s a comforting option that can brighten up any day.

If you’re looking for alternatives, Greek yogurt can replace sour cream for a similar texture and flavor. For those with dairy allergies, consider using plant-based yogurt and dairy-free chocolate chips. Be cautious with pumpkin puree versus pumpkin pie filling; the latter contains added spices and sugar, which could alter the intended flavor profile. Always ensure your bananas are very ripe for the best sweetness and moisture.

Double Chocolate Banana Bread Recipe
Ingredients
- 1 cup (127 grams) all-purpose flour
- 1/2 cup (43 grams) Dutch-process cocoa powder
- 1/2 cup (100 grams) granulated sugar
- 1/2 cup (100 grams) light brown sugar, packed
- 3/4 teaspoon baking soda
- 1/2 teaspoon fine sea salt
- 1 1/2 cups (340 grams) mashed banana, from about 3 very overripe bananas
- 1/2 cup (120 grams) sour cream, at room temperature
- 2 large eggs, lightly beaten, at room temperature
- 3 tablespoons (42 grams) unsalted butter, melted and cooled until just warm
- 3 tablespoons (34 grams) neutral oil, such as vegetable or avocado oil
- 1 teaspoon vanilla extract
- 1 cup (170 grams) semisweet chocolate chips
- 1/4 cup (43 grams) semisweet chocolate chips for topping
Instructions
- Let’s kick things off by preheating the oven to 350 degrees Fahrenheit. You’ll also want to grab a 9 by 5-inch metal loaf pan and line it with parchment paper, leaving a bit hanging over the edges for easy removal later on. A quick spray of nonstick cooking spray on that paper will definitely help too.
- In a large mixing bowl, combine 1 cup of all-purpose flour, 1/2 cup of Dutch-process cocoa powder, 1/2 cup of granulated sugar, 1/2 cup of light brown sugar, 3/4 teaspoon of baking soda, and 1/2 teaspoon of fine sea salt. Whisk those ingredients together until everything is well blended.
- Now, shift gears to another bowl where you can mash those bananas until they’re wonderfully smooth. After that, add in 1/2 cup of sour cream, 2 lightly beaten eggs, 3 tablespoons of melted butter, 3 tablespoons of neutral oil, and 1 teaspoon of vanilla extract. Mix it all up until you achieve a nice creamy consistency.
- Gently fold that wet mixture into the dry ingredients, mixing just until there’s no more visible flour. Once it looks good, carefully add in 1 cup of semisweet chocolate chips to ensure they’re well-distributed throughout the batter.
- Take that beautiful mixture and pour it into the prepared loaf pan, smoothing out the top with a spatula as you go. For an extra touch, sprinkle the remaining 1/4 cup of chocolate chips right on top of the batter.
- Baking time has arrived. Place that loaf in the oven for around 1 hour to 1 hour and 10 minutes. It’s ready when the top has a slight dome and a toothpick inserted in the center comes out with a few moist crumbs. Aim for an internal temperature of at least 200 degrees Fahrenheit.
- Once the baking is done, allow the bread to cool in the pan for 15 minutes. Use the parchment overhang to lift it out and set it on a wire rack to cool completely. If you feel like it, you can melt some extra chocolate chips to drizzle over the top and let it set before diving in.
Tips
- Make the batter ahead of time and store it in the refrigerator for up to 24 hours before baking for extra convenience.
- Store leftover banana bread wrapped in plastic wrap or foil at room temperature for up to 3 days, or refrigerate for up to 5 days.
- The banana bread freezes well; just wrap it tightly in plastic wrap and aluminum foil. Thaw at room temperature when you’re ready to enjoy it.
