Chocolate Zucchini Bread


After last year’s debacle, the year in which we planted 2 zucchini plants and 2 patty pans (to provide for three people), this year we thought we would approach the garden more intelligently, and plant only one zucchini and one patty pan.


Once again, we’re kicking off the summer with a zucchini beast madly producing more than we can eat. Fortunately, we have recipes like this one that use lots of zucchini, and we have friends and neighbors who happily accept the baked goods made from them.

This chocolate zucchini bread, for example, uses 4 whole cups of freshly grated zucchini, for two loaves. That’s at least a day or two of produce from our plant. Why four cups when most zucchini bead recipes call for three? Because the result is even more moist. And if you are buried in garden zucchini, why not?

A few notes about this recipe. Grated zucchini, from zucchini picked fresh from the garden, should be rather wet, which is what makes this bread so wonderfully moist. We recommend only making zucchini bread with zucchinis bought (or grown) in season, summer and early fall, otherwise the zucchini you buy from the store is likely shipped from far away and is too dry by the time it gets to you.

Chocolate Zucchini Bread

The zucchini from our garden is so heavy with moisture that we have to drain it over a sieve after grating it. If for some reason your grated zucchini is not moist, your zucchini bread will not be moist. In that case you may need to add some water to the recipe, or sprinkle some water over the grated zucchini until it feels moist.

This recipe calls for regular, not Dutch processed, unsweetened cocoa. This cocoa is slightly acidic (unlike the Dutch processed which is neutral in acidity), and reacts with the alkaline baking soda in the recipe to provide some of the bread’s leavening. (See this Wikipedia article for more explanation.) We used a Ghiradelli natural unsweetened cocoa powder for this recipe. The salt and the instant coffee are there to intensify the chocolate flavor.

We are using almond extract, but you can easily use vanilla extract instead, just use about 4 times as much, so instead of 1/2 teaspoon of almond extract, use 2 teaspoons of vanilla extract.

If you want, you can toss some chocolate chips into the batter. I’ve done that and don’t think it really adds anything to this zucchini bread, it’s chocolatey enough on its own. But for some people, you can never have enough chocolate, right?

Look who scarfed down the first loaf! Neighbors Emily, Andrew, Caleb, and Matthew.

Chocolate Zucchini Bread Recipe

  • Prep time: 10 minutes
  • Cook time: 1 hour, 10 minutes
  • Yield: Makes 2 loaves

This recipe makes 2 loaves; you can easily divide the recipe in half to make just one loaf. The recipe calls for 4 cups of grated zucchini, which will yield particularly moist loaves. I've made it with 3 cups, which was also very good, just not as sublime as with 4 cups.


  • 4 cups grated zucchini (from about a pound and a half of zucchini)
  • 2 1/2 cups all purpose flour
  • 1/2 cup unsweetened cocoa (use natural unsweetened cocoa, NOT Dutch processed)
  • 2 teaspoons baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon cinnamon
  • 1 1/2 cups granulated white sugar
  • 2 eggs
  • 3/4 cup unsalted butter (12 Tbsp or 1 1/2 sticks), melted
  • 1/2 teaspoon instant coffee granules
  • 1/2 teaspoon almond extract


1 Place the freshly grated zucchini in a sieve over a bowl to catch any excess moisture as it drains, while you work on prepping the other ingredients and preparing the recipe. If for some reason your zucchini is on the dry side, hydrate the shredded zucchini by soaking it in water first, and then place in sieve.


2 Preheat oven to 350°F, with a rack in the middle. Grease two 9x5-inch loaf pans with baking spray or butter.

3 Vigorously whisk together the flour, unsweetened cocoa, baking soda, salt, and cinnamon in a large bowl. Whisk until there are no more clumps and the ingredients are well combined.


4 In a separate large bowl, beat together the sugar and eggs until smooth, about a minute. You can do this with an electric mixer on medium speed, or by hand with a wooden spoon. (I'm lazy and use a mixer but it's easy enough to do by hand.) Add the melted butter, instant coffee granules, and almond extract and beat until smooth.

5 Mix the shredded zucchini into the sugar egg mixture. Add the flour to the zucchini mixture in 3 additions, stirring to combine after each addition.

6 Work quickly, and divide the batter between the two prepared loaf pans. (Work quickly because once the dry ingredients have mixed with the wet ingredients, the leavening has begun.)

Place into the oven. Bake for 50 minutes at 350°F, or until a skewer inserted into the center comes out clean and easily. Remove to a rack. Let cool in the pan for 5 minutes, then run a blunt knife around the edges to separate the bread from the pan. Remove from the loaf pans and let cool completely on a rack.

Note that if you try to slice the chocolate zucchini bread before it has completely cooled, it will be rather crumbly. It's also easiest to slice with a bread knife.

    I would like to ask about your zucchini. What type do you plant? What about your soil? I used to grow them like crazy but the last 3 season have been a bust. :( Have no clue what has gone wrong.

    I used store bought zucchini and it turned out. Of course I got it at Sprouts and not the big box store.

    Awesome recipe!

    Thought I would share an experiment gone… Fantastic!!… with this recipe. I made the batter as directed, but used a mini muffin pan and a mini loaf pan instead. I had a small amount of batter left but didn’t want to waste it so I sprayed up a small crock and dumped in the remaining batter. (It was only about 1/4 in high in the dish.)

    I went to put all three baking pans in the oven but the crock didn’t fit. So I baked the two pans and stared at the crock thinking… I don’t want to wait that long to cook this, so….I put the crock in the microwave on high (no setting adjustments needed) and cooked it for 2.5 minutes watching it the whole time. To my surprise it was perfectly cooked, with the center springing back nicely to the touch! When we tried it…. It was absolutely heavenly! I have a picture of the end product if you want to see it. :)

    Just made this to take to the office tomorrow to use up some very abundant zuke plants. I didn’t have instant coffee so just poured about 1/4 cup of leftover coffee over the zucc as they drained. Turned out great, but didn’t rise as much as I expected or saw in the pics, but tastes great.

    I just made this today and put a single recipe into 3 smaller loaf pans. It is so good, I’ll definitely be making more to give away to neighbors.
