How to Make Chocolate Zucchini Banana Bread

The method for making this bread just couldn’t be easier. It is truly a foolproof recipe. So use what you have on hand and let’s get started.

Firstly, you need to mash the bananas in a large bowl. You are looking to get about one cup of mashed banana: two large bananas or three medium bananas should work. (I personally never measure exactly how much mashed bananas I get and just use what I have.)

Next, whisk in the eggs, sugar, and oil. Mix together the dry ingredients and combine with the wet until well combined. *See the note on cocoa powder below.

Lastly, fold in the grated zucchini and half of the mini chips. I use the large holes on the box grater to grate my zucchini.

Also, if you come up short of two cups or only have one zucchini, just use what you have. If your zucchini happens to be really wet, you may need to squeeze it in a paper towel before adding it to the batter, although I’ve never had to do this.

Pour the batter into a greased pan and sprinkle on remaining chips. Bake until a toothpick inserted in the center comes out batter free. This is a moist bread, so you may have some crumbs sticking to the toothpick.

Let the bread cool for at least 15 minutes before removing from pan. Let cool completely on a wire rack before cutting… if you can!

A note on Cocoa Powder

Cocoa powder is available in two forms: natural (often just labeled “unsweetened cocoa”) and Dutch-processed cocoa. The difference in pH levels of Dutch-processed cocoa and natural cocoa powder means they will react differently depending on the leavener in a recipe.

In general, use natural cocoa powder for recipes made with alkaline leaveners like baking soda, and Dutch-processed cocoa for recipes made with baking powders.

  • For each three tablespoons Dutch-processed cocoa powder, substitute three tablespoons natural cocoa powder plus ⅛ teaspoon baking soda.
  • For each three tablespoons natural cocoa powder, substitute three tablespoons Dutch-processed cocoa powder plus ⅛ teaspoon cream of tartar.

And now you know all you need to know about the differences between natural and Dutch-processed cocoa powder! So use what you have to make this delicious Chocolate Zucchini Banana Bread recipe.

    This was so good! I used 1/3 cup cocoa powder just as someone else suggested. I substituted ff greek yogurt for the oil. The amount of sugar was perfect, just lightly sweet. Thank you for the great recipe. I’ll definitely make it again!

    Very tasty and mildly sweet! Great way to use up over ripe bananas and all those zucchini from the garden. I increased the cocoa to 1/3 cup and the cinnamon to 1 tsp. Didn’t have mini chips so just used regular sprinkled on top. Baked in a 9×5 loaf pan for 55 min. Delicious!

  3. My question is, if I use mini bread baking pans, what is recommended baking time? The same? I’m definitely going to be making this very soon.

    1. I would try halving the baking time to start. You will need to use a toothpick to test for doneness. Enjoy!
