Ingredients You’ll Need
Most of these items are likely already in your pantry. Use your darkest bananas for the best natural sweetness.
- 2 large overripe bananas, mashed (approx. 1 cup)
- 1 cup zucchini, finely shredded and squeezed dry
- 1/2 cup unsalted butter, melted and cooled
- 3/4 cup light brown sugar, packed
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
- 1 1/2 cups all-purpose flour
- 1/2 cup unsweetened Dutch-process cocoa powder
- 1 teaspoon baking soda
- 1/2 teaspoon kosher salt
- 3/4 cup semi-sweet chocolate chips, divided
Step-by-Step Directions
- Preheat the oven to 350°F (175°C) and grease a 9×5 inch loaf pan with butter or non-stick spray.
- In a medium mixing bowl, sift together the all-purpose flour, cocoa powder, baking soda, and salt.
- In a separate large bowl, whisk the mashed bananas, melted butter, brown sugar, egg, and vanilla extract until well combined.
- Gradually fold the dry ingredients into the wet mixture using a spatula until just combined, ensuring no large pockets of flour remain.
- Gently fold in the shredded zucchini and 1/2 cup of the chocolate chips.
- Transfer the batter to the prepared loaf pan and smooth the top with a spatula.
- Sprinkle the remaining 1/4 cup of chocolate chips evenly over the surface of the batter.
- Bake for 55 to 65 minutes, or until a cake tester inserted into the center comes out clean or with only a few moist crumbs.
- Cool the bread in the pan for 15 minutes before transferring to a wire rack to cool completely.
Best Ways to Enjoy It
Serve a thick slice warm with a smear of salted butter. The butter melts into the chocolate chips for a rich treat. It pairs perfectly with your morning coffee or a glass of milk.
Pack a slice into your child’s lunchbox for a fun school surprise. You can also toast a piece for a crispy, warm texture. Enjoy it as a simple dessert after a summer BBQ.
Keep It Fresh
Store leftovers in an airtight container at room temperature for two days. For longer storage, keep the bread in the fridge for five days. This bread actually gets moister on the second day.
You can also freeze individual slices for easy meal prep snacks. Wrap them tightly in plastic wrap and place in a freezer bag. Reheat in the microwave for 20 seconds for a fresh-baked feel.
Tips for Best Results
- Squeeze the shredded zucchini very dry using a clean kitchen towel.
- Don’t overmix the batter or the bread will become tough.
- Use a room temperature egg to ensure a smooth, even batter.
- Measure your flour using the spoon-and-level method for accuracy.
- Add a handful of fresh summer walnuts for extra crunch.
- Check the bread at 55 minutes to prevent over-baking.
Easy Flavor Ideas
- Swap the chocolate chips for white chocolate for a sweeter contrast.
- Use a gluten-free 1:1 baking flour to make this allergy-friendly.
- Add a dash of cinnamon to enhance the warm banana flavors.
- Replace the butter with coconut oil for a subtle tropical note.
Common Questions
Do I need to peel the zucchini?
No, you do not need to peel it. The skin is thin and softens completely while baking. It adds beautiful tiny flecks of color to the bread.
Can I use frozen bananas?
Yes, frozen bananas work very well in this recipe. Thaw them completely and drain any excess liquid before mashing. They provide a very soft and sweet texture.
Is this bread very sweet?
It has a balanced sweetness from the bananas and brown sugar. The dark cocoa powder keeps it from being too sugary. It feels more like a rich snack than a candy bar.
I hope this chocolate zucchini banana bread helps you enjoy your summer harvest. It is a wonderful way to bring the family together in the kitchen. Happy baking!
