Why You’ll Love This Chocolate Zucchini Bread
You will love this chocolate zucchini bread because it is soft, moist, chocolatey, and easy to make. It has the flavor of chocolate cake but the simple shape of a quick bread loaf.
The shredded zucchini adds moisture without making the bread taste like vegetables. This makes it a great hidden veggie recipe for kids and adults. Even people who say they do not like zucchini usually enjoy this bread because the chocolate flavor is the main thing you taste.
This recipe also uses basic ingredients. Flour, cocoa powder, sugar, oil, eggs, vanilla, baking soda, baking powder, zucchini, and chocolate chips come together to make a rich homemade loaf.
Another reason this recipe is so useful is that it stores well. The bread stays moist at room temperature for a couple of days and can be refrigerated or frozen for later. You can bake one loaf and enjoy slices throughout the week.
It is also easy to customize. Add walnuts, espresso powder, cinnamon, peanut butter chips, dark chocolate chunks, or a simple chocolate glaze if you want to make it more special.
What Is Chocolate Zucchini Bread?
Chocolate zucchini bread is a quick bread made with shredded zucchini and cocoa powder. It is similar to regular zucchini bread, but richer and more chocolate-forward. The zucchini is mixed into the batter and bakes into the loaf, adding moisture and tenderness.
It is called a quick bread because it does not use yeast. Instead, baking soda and baking powder help the loaf rise. This makes the recipe faster and easier than traditional bread.
The texture is soft and moist, somewhere between a muffin, loaf cake, and brownie. It is not as dense as brownies, but it is richer than plain zucchini bread.
Chocolate zucchini bread is especially popular during summer when zucchini is abundant. It is a smart way to use extra zucchini in a sweet recipe that feels like dessert.
Ingredients
- 1 1/2 cups shredded zucchini
- 1 1/2 cups all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 3/4 cup granulated sugar
- 1/3 cup brown sugar, packed
- 1/2 cup vegetable oil or melted coconut oil
- 2 large eggs
- 1/4 cup Greek yogurt or sour cream
- 1 teaspoon vanilla extract
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 1/2 teaspoon cinnamon, optional
- 3/4 cup semi-sweet chocolate chips, plus extra for topping
Ingredient Notes
Zucchini is the key ingredient for moisture. Use fresh zucchini and shred it with a box grater. You do not need to peel it. The skin is soft and blends into the bread.
All-purpose flour gives the loaf structure. Measure it correctly by spooning it into the measuring cup and leveling it off. Too much flour can make the bread dry.
Cocoa powder gives the bread rich chocolate flavor. Use unsweetened cocoa powder. Natural cocoa powder works well, but Dutch-process cocoa can also be used for a darker flavor.
Granulated sugar adds sweetness and helps create a tender crumb.
Brown sugar adds moisture and deeper flavor. It helps make the bread softer and more rich.
Oil keeps the bread moist. Vegetable oil has a neutral flavor, while melted coconut oil can add a slight coconut note.
Eggs bind the batter and help the loaf rise.
Greek yogurt or sour cream adds extra moisture and softness. It also gives the bread a slightly richer texture.
Vanilla extract rounds out the chocolate flavor.
Baking soda and baking powder help the bread rise and keep the texture light.
Salt balances the sweetness and strengthens the chocolate flavor.
Cinnamon is optional, but it adds warmth. You will not strongly taste it, but it makes the chocolate flavor feel deeper.
Chocolate chips make the bread extra rich and dessert-like. Adding some on top also makes the loaf look more appealing.
Best Zucchini To Use
Small to medium zucchini are best for chocolate zucchini bread. They are tender, mild, and easy to shred. Their seeds are smaller, and they have the right amount of moisture.
Large zucchini can also be used, but they may have big seeds and extra water. If using a large zucchini, cut it in half lengthwise and scoop out the seedy center before shredding.
Choose zucchini that feels firm and has smooth skin. Avoid zucchini that is soft, wrinkled, or bitter-smelling.
Should You Peel Zucchini For Zucchini Bread?
No, you do not need to peel zucchini. The skin is thin and soft, and it blends into the loaf during baking. In chocolate zucchini bread, the cocoa powder hides most of the green color.
Leaving the peel on also saves time and keeps the recipe simple.
If you want the zucchini to disappear even more, shred it finely. Finely shredded zucchini blends into the batter better than thick shreds.
Should You Squeeze The Zucchini?
For this recipe, you should lightly squeeze the zucchini only if it is very watery. Do not squeeze it completely dry.
Zucchini moisture is important because it helps make the bread soft and tender. If you remove too much moisture, the loaf may turn out dry.
After shredding the zucchini, let it sit for a few minutes. If liquid pools at the bottom, gently press out some of the excess. The zucchini should still feel moist.
How To Shred Zucchini
Wash and dry the zucchini. Trim off the ends. Use a box grater to shred the zucchini.
The large holes of the grater create visible shreds and a little more texture. The smaller holes make finer shreds that disappear more into the bread.
Measure the zucchini after shredding. You need 1 1/2 cups of shredded zucchini for this recipe.
How To Make Chocolate Zucchini Bread
Step 1: Prepare The Loaf Pan
Preheat the oven to 350°F. Grease a 9×5-inch loaf pan or line it with parchment paper. Parchment paper makes it easier to lift the loaf out after baking.
Set the pan aside while you prepare the batter.
Step 2: Shred The Zucchini
Shred the zucchini and measure 1 1/2 cups. If it is extremely wet, lightly squeeze out extra liquid. Do not dry it completely.
Set the shredded zucchini aside.
Step 3: Mix The Dry Ingredients
In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder, salt, and cinnamon if using.
Whisking the dry ingredients helps break up cocoa powder clumps and evenly distributes the leavening.
Step 4: Mix The Wet Ingredients
In a large bowl, whisk together the granulated sugar, brown sugar, oil, eggs, Greek yogurt, and vanilla extract until smooth.
The mixture should look glossy and well combined.
Step 5: Add The Zucchini
Stir the shredded zucchini into the wet ingredients. The mixture may look thick and textured, which is normal.
Step 6: Combine The Batter
Add the dry ingredients to the wet ingredients. Stir gently until just combined.
Do not overmix the batter. Overmixing can make quick bread dense or tough.
Step 7: Add Chocolate Chips
Fold in the chocolate chips. Save a small handful to sprinkle over the top of the loaf before baking.
The chocolate chips melt into the bread and make each slice more rich and chocolatey.
Step 8: Bake
Pour the batter into the prepared loaf pan and smooth the top. Sprinkle extra chocolate chips over the surface.
Bake for 50 to 60 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. If the toothpick has wet batter, bake for a few more minutes.
If the top starts browning too quickly, loosely tent the loaf with foil during the last 10 to 15 minutes.
Step 9: Cool Before Slicing
Let the bread cool in the pan for about 15 minutes. Then transfer it to a wire rack to cool completely.
For clean slices, wait until the loaf is fully cool. Warm bread tastes delicious, but it can crumble if sliced too soon.
Tips For The Best Chocolate Zucchini Bread
Use fresh zucchini for the best moisture and flavor.
Do not squeeze the zucchini completely dry. The moisture helps keep the bread soft.
Measure the flour correctly. Too much flour can make the loaf dry.
Use good cocoa powder because chocolate flavor is important in this recipe.
Do not overmix the batter once the flour is added.
Add chocolate chips to make the bread richer and more dessert-like.
Let the loaf cool before slicing so the crumb can set.
If you want a very moist loaf, wrap it after cooling and let it sit for a few hours before slicing. Quick breads often taste even better the next day.
How To Know When Chocolate Zucchini Bread Is Done
Chocolate zucchini bread is done when the top looks set, the loaf has risen, and a toothpick inserted into the center comes out with moist crumbs.
Because this bread is dark from cocoa powder, it can be harder to judge by color. Use the toothpick test.
Avoid overbaking. A few moist crumbs are good. Wet batter means it needs more time.
The center should not jiggle when the pan is gently moved.
Can You Taste The Zucchini?
No, you usually cannot taste the zucchini. The cocoa powder, sugar, vanilla, and chocolate chips create a strong chocolate flavor.
The zucchini mainly adds moisture. If shredded finely, it nearly disappears into the bread.
Some tiny green specks may be visible, especially near the edges, but the flavor remains chocolatey.
Chocolate Zucchini Bread Variations
Double Chocolate Zucchini Bread
Add extra chocolate chips to the batter and more on top. This makes the loaf rich and bakery-style.
Walnut Chocolate Zucchini Bread
Fold in 1/2 cup chopped walnuts or pecans. Nuts add crunch and pair well with chocolate.
Espresso Chocolate Zucchini Bread
Add 1 teaspoon espresso powder to the dry ingredients. It deepens the chocolate flavor without making the bread taste strongly like coffee.
Peanut Butter Chocolate Zucchini Bread
Swirl 1/4 cup peanut butter into the top of the batter before baking. You can also add peanut butter chips.
Chocolate Chip Zucchini Muffins
Use this batter to make muffins instead of a loaf. Fill muffin cups about three-quarters full and bake for about 18 to 22 minutes.
Chocolate Glazed Zucchini Bread
After the loaf cools, drizzle with a simple chocolate glaze made with powdered sugar, cocoa powder, milk, and vanilla.
What To Serve With Chocolate Zucchini Bread
Chocolate zucchini bread can be served in many ways.
Serve it plain as a snack.
Warm a slice and add a little butter.
Serve with coffee or tea for breakfast or brunch.
Add a scoop of vanilla ice cream for dessert.
Top with whipped cream and berries for a more special treat.
Spread with peanut butter for a richer snack.
Serve with cold milk for a kid-friendly dessert.
It also works well on brunch boards with fruit, muffins, yogurt, and coffee.
How To Store Chocolate Zucchini Bread
Let the loaf cool completely before storing. Wrap it tightly in plastic wrap or place it in an airtight container.
Store at room temperature for up to 2 days. Because this bread is moist, refrigerate it for longer storage.
In the refrigerator, it can last up to 5 days. Let slices come to room temperature or warm them slightly before serving.
Can You Freeze Chocolate Zucchini Bread?
Yes, chocolate zucchini bread freezes well.
Let the loaf cool completely. Wrap the whole loaf tightly in plastic wrap and then foil, or slice it and freeze individual slices.
Freeze for up to 3 months.
To serve, thaw overnight in the refrigerator or at room temperature. Individual slices can also be warmed briefly in the microwave.
Can You Make This Recipe Into Muffins?
Yes. This recipe can be used to make chocolate zucchini muffins.
Line a muffin pan with paper liners or grease it well. Fill each cup about three-quarters full. Bake at 350°F for 18 to 22 minutes, or until a toothpick comes out with moist crumbs.
Muffins are great for lunchboxes, snacks, and freezing.
Can You Make It Gluten-Free?
Yes. Use a 1:1 gluten-free all-purpose flour blend designed for baking.
The texture may vary slightly depending on the blend, but the loaf should still be moist and chocolatey.
Can You Make It Dairy-Free?
Yes. Use dairy-free chocolate chips and replace Greek yogurt or sour cream with a dairy-free yogurt.
Vegetable oil is already dairy-free, and the rest of the recipe can easily be adjusted.
Can You Make It Without Eggs?
You can try using flax eggs. To replace 2 eggs, mix 2 tablespoons ground flaxseed with 6 tablespoons water. Let it sit for 5 to 10 minutes until thickened.
The loaf may be slightly softer and more delicate, but it can still work.
Common Mistakes To Avoid
Do not use too much flour. This is one of the most common reasons quick breads turn out dry.
Do not squeeze all the water out of the zucchini. The zucchini moisture is important.
Do not overmix the batter. Stir just until combined.
Do not slice the bread too soon. Let it cool so the crumb sets.
Do not overbake. Chocolate bread can look done before it actually is, so use a toothpick test.
Do not skip the chocolate chips if you want a rich dessert-style loaf.
