Zucchini Brownies
These zucchini brownies are rich, chocolatey, fudgy, and surprisingly easy to make with freshly shredded zucchini. They are the kind of brownies that taste indulgent and dessert-like, but they also use a simple summer vegetable in a clever way. If you have extra zucchini from the garden, farmers market, or grocery store, this is one of the best sweet recipes to make with it.
The best part about zucchini brownies is that you do not really taste the zucchini. Instead, the shredded zucchini adds moisture and helps create a soft, fudgy texture. The brownies taste like chocolate first. They are dense, tender, slightly chewy around the edges, and rich enough to satisfy a serious chocolate craving.
Zucchini is often used in quick breads and muffins, but it works beautifully in brownies too. Because zucchini naturally contains a lot of water, it helps keep the brownies moist without making them heavy. When mixed with cocoa powder, sugar, flour, oil, vanilla, and chocolate chips, the zucchini blends into the batter and almost disappears.
These brownies are perfect for summer baking, after-school snacks, lunchbox treats, potlucks, bake sales, family desserts, or anytime you want a homemade chocolate dessert. They are also a great recipe for people who say they do not like zucchini, because the flavor is hidden behind rich chocolate.
Why You’ll Love These Zucchini Brownies
You will love these zucchini brownies because they are fudgy, chocolatey, and easy to make with basic ingredients. They do not require fancy equipment, and you do not need to make frosting unless you want to.
This recipe is a great way to use extra zucchini. During summer, zucchini can pile up quickly, and it is easy to get tired of savory zucchini recipes. These brownies turn zucchini into a dessert that everyone actually wants to eat.
Another reason this recipe works so well is the texture. The shredded zucchini releases moisture as the brownies bake, helping them stay soft and rich. Instead of dry, cakey brownies, you get a tender brownie with a fudgy bite.
These brownies are also easy to customize. You can add chocolate chips, chopped walnuts, espresso powder, cinnamon, frosting, or a sprinkle of sea salt. You can keep them simple or make them extra decadent.
They are also kid-friendly because the zucchini is hidden. If the zucchini is shredded finely, most people will not notice it at all.
What Are Zucchini Brownies?
Zucchini brownies are chocolate brownies made with shredded zucchini mixed into the batter. The zucchini adds moisture but does not give the brownies a strong vegetable taste.
They are similar to classic brownies, but the batter may look a little different at first. Because zucchini releases water while baking, the batter can seem thicker before it goes into the pan. As it bakes, the zucchini softens and helps create a rich brownie texture.
Some zucchini brownie recipes are cakey, while others are fudgy. This recipe is designed to be moist and fudgy with plenty of chocolate flavor.
Ingredients
- 2 cups shredded zucchini
- 1 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 3/4 cup granulated sugar
- 1/2 cup brown sugar, packed
- 1/2 cup vegetable oil or melted coconut oil
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup semi-sweet chocolate chips
- 1/2 cup chopped walnuts, optional
Ingredient Notes
Zucchini is the key ingredient. Use fresh zucchini and shred it with a box grater. Medium or small zucchini usually work best because they are tender and not too seedy.
All-purpose flour gives the brownies structure. Measure it correctly by spooning it into the measuring cup and leveling it off. Too much flour can make brownies dry.
Cocoa powder gives the brownies their chocolate flavor. Use unsweetened cocoa powder. Dutch-process cocoa can also work, but natural cocoa powder is a good standard choice.
Granulated sugar adds sweetness and helps create classic brownie texture.
Brown sugar adds moisture and deeper flavor. It gives the brownies a softer, richer bite.
Oil keeps the brownies moist. Vegetable oil works well because it has a neutral flavor. Melted coconut oil can also be used, but it may add a slight coconut taste.
Eggs help bind the batter and give the brownies structure.
Vanilla extract makes the chocolate flavor taste warmer and more balanced.
Baking soda gives the brownies a little lift without making them too cakey.
Salt balances the sweetness and makes the chocolate flavor stronger.
Chocolate chips add melted pockets of chocolate throughout the brownies. They also make the brownies look more tempting on top.
Walnuts are optional. They add crunch and pair well with chocolate, but you can leave them out for a smoother brownie.
Best Zucchini To Use
The best zucchini for brownies is fresh, firm, and medium-sized. Small and medium zucchini have tender skin, mild flavor, and fewer seeds.
Large overgrown zucchini can still be used, but they often have more water and larger seeds. If using a large zucchini, cut it in half lengthwise and scoop out the seedy center before shredding.
You do not need to peel zucchini before using it. The skin is soft, edible, and blends into the brownies. It also adds tiny green specks, but they are usually hard to notice once mixed with cocoa powder.
Should You Squeeze The Zucchini?
For this recipe, lightly squeeze the zucchini only if it is extremely wet. You do not want to remove all the moisture because that moisture helps create fudgy brownies.
After shredding the zucchini, let it sit for a few minutes. If there is a lot of liquid pooling at the bottom, gently press out some of the extra water. Do not squeeze it completely dry.
The goal is moist shredded zucchini, not dripping wet zucchini and not dry zucchini.
How To Shred Zucchini For Brownies
Wash and dry the zucchini. Trim off the ends. Use the large holes of a box grater to shred it.
If you want the zucchini to disappear more into the brownies, use the smaller holes of the grater. Finely shredded zucchini blends better into the batter and is harder to notice.
Measure the zucchini after shredding. You need about 2 cups of shredded zucchini.
How To Make Zucchini Brownies
Step 1: Prepare The Pan
Preheat the oven to 350°F. Line an 8×8-inch baking pan with parchment paper or lightly grease it with nonstick spray.
Parchment paper makes it easier to lift the brownies out of the pan after baking.
Step 2: Shred The Zucchini
Shred the zucchini using a box grater. Measure 2 cups of shredded zucchini. If it seems very watery, gently squeeze out a little liquid, but do not dry it completely.
Set the zucchini aside.
Step 3: Mix The Dry Ingredients
In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt. Mixing the dry ingredients separately helps prevent clumps of cocoa powder and makes the batter smoother.
Step 4: Mix The Wet Ingredients
In a large bowl, whisk together granulated sugar, brown sugar, oil, eggs, 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. At first, it may look like a lot of zucchini, but it will blend into the batter as everything comes together.
Step 6: Combine Wet And Dry Ingredients
Add the dry ingredients to the wet mixture. Stir until just combined. The batter may look thick at first, but the zucchini will release moisture as you mix.
Do not overmix. Overmixing can make brownies tougher.
Step 7: Add Chocolate Chips
Fold in the chocolate chips and walnuts if using. Save a few chocolate chips to sprinkle on top if you want the brownies to look extra chocolatey.
Step 8: Bake
Spread the batter evenly into the prepared pan. Sprinkle extra chocolate chips on top if desired.
Bake for 28 to 35 minutes, or until the edges are set and a toothpick inserted into the center comes out with moist crumbs. Do not overbake. For fudgy brownies, the toothpick should not come out completely clean.
Step 9: Cool Before Slicing
Let the brownies cool completely in the pan before slicing. This helps them set and makes cleaner squares.
If you slice them while hot, they may fall apart. They taste amazing warm, but they cut better after cooling.
Tips For The Best Zucchini Brownies
Use fresh zucchini for the best moisture and texture.
Do not squeeze the zucchini completely dry. The moisture is important for fudgy brownies.
Measure flour correctly. Too much flour can make brownies dry and cakey.
Do not overbake. Brownies continue to set as they cool.
Use chocolate chips for extra richness. They make the brownies taste more indulgent.
Let the brownies cool before slicing. This gives them time to firm up.
For extra fudgy brownies, refrigerate them after cooling. Cold brownies often taste denser and richer.
How To Make Zucchini Brownies More Fudgy
For fudgier brownies, avoid overbaking. Pull them from the oven when the center still has moist crumbs.
You can also add an extra 1/4 cup chocolate chips to the batter for more melted chocolate texture.
Using brown sugar helps keep the brownies moist and chewy. Do not replace all the brown sugar with white sugar if you want a fudgy texture.
Cooling completely is also important. Brownies firm up as they cool, and the texture becomes denser.
Can You Taste The Zucchini?
No, these brownies do not taste like zucchini. The cocoa powder, sugar, vanilla, and chocolate chips create a strong chocolate flavor that hides the zucchini.
The zucchini’s main job is to add moisture. If you shred it finely, it becomes almost invisible in the brownies.
People may notice tiny green specks if they look closely, but the taste is chocolatey.
Can You Make These Brownies Without Eggs?
Yes, you can try making them egg-free by using flax eggs. To make one flax egg, mix 1 tablespoon ground flaxseed with 3 tablespoons water and let it sit for 5 minutes. For this recipe, use two flax eggs.
The texture may be slightly softer and less structured, but it can still work.
Can You Make Zucchini Brownies Gluten-Free?
Yes. Use a 1:1 gluten-free all-purpose flour blend in place of regular flour. Make sure the blend is designed for baking.
The texture may vary slightly depending on the flour blend, but the brownies should still be moist and chocolatey.
Can You Add Frosting?
Yes. Zucchini brownies are delicious with chocolate frosting. You can spread frosting on top after the brownies cool completely.
A simple chocolate frosting can be made with butter, cocoa powder, powdered sugar, vanilla, and a little milk. Cream cheese frosting also works if you like a tangy contrast.
For a lighter option, dust the brownies with powdered sugar instead of frosting.
Zucchini Brownie Variations
Double Chocolate Zucchini Brownies
Add extra chocolate chips to the batter and sprinkle more on top before baking.
Walnut Zucchini Brownies
Add chopped walnuts for crunch and a classic brownie flavor.
Espresso Zucchini Brownies
Add 1 teaspoon espresso powder to the dry ingredients. It will not make the brownies taste like coffee, but it will deepen the chocolate flavor.
Sea Salt Zucchini Brownies
Sprinkle flaky sea salt on top before baking. This creates a sweet-salty chocolate flavor.
Frosted Zucchini Brownies
Let the brownies cool and spread chocolate frosting on top for a bakery-style dessert.
Cinnamon Chocolate Zucchini Brownies
Add 1/2 teaspoon cinnamon to the dry ingredients for a warm flavor.
How To Store Zucchini Brownies
Store zucchini brownies in an airtight container at room temperature for up to 2 days. Because they are very moist, they should be refrigerated for longer storage.
In the refrigerator, they can last up to 5 days. The texture becomes denser and fudgier when chilled.
Let refrigerated brownies sit at room temperature for a few minutes before serving if you prefer them softer.
Can You Freeze Zucchini Brownies?
Yes. Zucchini brownies freeze well.
Let them cool completely, then cut them into squares. Place the squares in a freezer-safe bag or container with parchment paper between layers. Freeze for up to 3 months.
Thaw at room temperature or in the refrigerator before serving.
What To Serve With Zucchini Brownies
Zucchini brownies are delicious on their own, but you can also serve them with:
- Vanilla ice cream
- Whipped cream
- Fresh berries
- Chocolate sauce
- Caramel sauce
- Powdered sugar
- Cold milk
- Coffee
- Greek yogurt
For a dessert plate, serve a brownie warm with vanilla ice cream and a few chocolate chips on top.
Common Mistakes To Avoid
Do not use too much flour. This can make the brownies dry.
Do not overbake. Overbaked brownies lose their fudgy texture.
Do not squeeze the zucchini completely dry. The brownies need that moisture.
Do not skip the cooling time. Cooling helps the brownies set.
Do not use old, bitter zucchini. Fresh zucchini gives the best result.
Do not overmix the batter after adding flour.
