Ingredients
Rich and fudgy brownies with hidden zucchini and the best frosting you’ll ever eat!
For the Brownies:
- 2 cups (248g) all-purpose flour
- ½ cup (40g) unsweetened cocoa powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- ½ cup (118g) vegetable oil
- 1 ½ cups (300g) granulated sugar
- 2 teaspoons vanilla extract
- 2 cups shredded zucchini (1 large or 2 small zucchinis)
- 3-5 tablespoons (15-75ml) water
- ½ cup chopped walnuts (optional)
For the Frosting:
- 3 tablespoons (15g) unsweetened cocoa powder
- ¼ cup (59ml) unsalted butter (melted)
- 2 cups powdered sugar
- ¼ cup (59ml) milk
- 1 teaspoon vanilla extract
- Pinch of salt
How to Make Zucchini Brownies
Step 1: Preheat the Oven
Preheat your oven to 350°F. Line a 9×13 baking pan with foil and spray it with cooking spray. Set aside to prepare for pouring in your delicious batter.
Step 2: Prepare Dry Ingredients
In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. This step ensures that all dry ingredients are evenly distributed before adding them to your wet mixture.
Step 3: Mix Wet Ingredients
Using an electric mixer fitted with a paddle attachment, mix together the vegetable oil, granulated sugar, and vanilla extract until well combined.
Step 4: Combine Batter
Add in the dry ingredients from Step 2 and stir until just mixed. Gently fold in the shredded zucchini. Allow the batter to sit for a few minutes so it can absorb moisture from the zucchini. If your mixture is still too dry after resting, gradually mix in up to 5 tablespoons of water until you achieve a thick but workable consistency.
Step 5: Bake
Spread the brownie batter evenly into your prepared pan. Bake for about 25-30 minutes or until they spring back when gently touched.
Step 6: Make the Frosting
For an amazing topping, whisk together melted butter, cocoa powder, salt, powdered sugar, milk, and vanilla extract until smooth. Spread it over cooled brownies once they are completely cool.
Step 7: Chill & Serve
Cut into squares and chill briefly so that the frosting semi-sets while remaining gooey underneath.

How to Serve Zucchini Brownies
Zucchini brownies are a delightful twist on traditional brownies that can be enjoyed in various ways. Here are some creative serving suggestions to enhance your experience.
With a Scoop of Ice Cream
- Vanilla or chocolate ice cream pairs beautifully with the fudgy texture of zucchini brownies, adding a creamy contrast.
Drizzled with Chocolate Sauce
- A warm drizzle of chocolate sauce elevates the brownies, making them even more indulgent and delicious.
Topped with Fresh Berries
- Add a fresh touch by topping your brownies with mixed berries, which provide a burst of flavor and color.
Served with Whipped Cream
- A dollop of whipped cream on top creates a light and airy addition that complements the rich, chocolatey brownies.
As Part of a Dessert Platter
- Slice the brownies into bite-sized pieces and serve them alongside other desserts for variety at gatherings or parties.
How to Perfect Zucchini Brownies
Perfecting your zucchini brownies is all about balancing moisture and richness. Here are some tips to ensure they turn out just right.
- Measure Zucchini Correctly: Use packed shredded zucchini to get the right moisture without making the batter too wet.
- Adjust Water Carefully: Start with less water when mixing; add more only if needed. Too much water can lead to cakey brownies.
- Let Batter Rest: Allowing the batter to sit for a few minutes helps it absorb moisture from the zucchini before baking.
- Check Baking Time: Test for doneness by gently pressing the center; if it springs back, it’s ready. Avoid overbaking for fudgier results.
- Cool Before Frosting: Always let the brownies cool completely before adding frosting to prevent it from melting away.
Best Side Dishes for Zucchini Brownies
While zucchini brownies are delicious on their own, serving them alongside complementary side dishes can enhance your dessert experience. Here are some great options:
- Fresh Fruit Salad: A refreshing mix of seasonal fruits adds brightness and balances the richness of the brownies.
- Vanilla Yogurt: Creamy yogurt provides a tangy contrast that pairs well with sweet desserts like zucchini brownies.
- Chocolate-Covered Strawberries: These add an elegant touch and more chocolate flavor, making your dessert spread even more appealing.
- Nutty Granola: Sprinkle some crunchy granola for added texture and flavor that contrasts nicely with the soft brownies.
- Coffee or Espresso: A cup of strong coffee enhances the chocolatey taste and provides a nice pick-me-up after dessert.
- Homemade Caramel Sauce: Drizzling warm caramel over each brownie will add an extra layer of sweetness that’s hard to resist.
Common Mistakes to Avoid
When making Zucchini Brownies, there are a few common pitfalls to watch out for to ensure your brownies turn out perfectly fudgy.
- Incorrect Water Measurement: Adding too much water can lead to cakey brownies. Start with one tablespoon and gradually add more as needed, ensuring the batter remains thick.
- Overmixing the Batter: Mixing the batter too much can cause the brownies to become tough. Mix just until combined and avoid overworking it.
- Not Prepping the Pan Properly: Skipping the foil and cooking spray can result in stuck brownies. Always line your baking pan for easy removal.
- Ignoring Baking Time: Overbaking can dry out your brownies. Keep an eye on them, and remove them when they spring back when touched gently.
- Using Wet Zucchini: If your zucchini is too wet, it may affect the batter consistency. Pat it dry with a paper towel before adding it to the mix.
