Ingredients
For the Brownies
- ½ cup (112 g) vegetable oil
- 1 ½ cups (300 g) granulated sugar
- 1 tablespoon vanilla extract
- 2 cups (256 g) all-purpose flour
- ½ cup (64 g) unsweetened cocoa powder
- 1 ½ teaspoon baking soda
- 1 teaspoon kosher salt
- 3 cups finely shredded zucchini (DO NOT DRAIN)
- 1 ¼ cups semi-sweet chocolate chunks
How to Make Zucchini Brownies
Step 1: Preheat the Oven
Preheat your oven to 350°F. Prepare a 9×13 inch pan by greasing it with butter or using baking spray. Line the bottom with parchment paper, allowing it to go up the sides for easy removal later.
Step 2: Mix Wet Ingredients
In a large bowl, combine the following:
1. ½ cup vegetable oil
2. 1 ½ cups granulated sugar
3. 1 tablespoon vanilla extract
Whisk these ingredients together until they are fully incorporated.
Step 3: Add Dry Ingredients
Next, add:
1. 2 cups all-purpose flour
2. ½ cup unsweetened cocoa powder
3. 1 ½ teaspoons baking soda
4. 1 teaspoon kosher salt
Mix until combined; note that the batter will be very dry at this stage.
Step 4: Incorporate Zucchini
Fold in:
– 3 cups finely shredded zucchini (DO NOT DRAIN)
Allow the batter to rest for about 5 minutes to help hydrate the flour.
Step 5: Add Chocolate Chunks
Stir in:
– 1 ¼ cups semi-sweet chocolate chunks
At this point, your batter should look more wet. If it still appears dry after resting for another 5 minutes, stir again.
Step 6: Bake the Brownies
Spread your brownie mixture evenly into the prepared pan. Bake for about 25–35 minutes. To check if they’re done, insert a toothpick; it should come out with crumbs but no wet batter attached.
Enjoy your deliciously moist Zucchini Brownies—a sweet treat that surprises with every bite!

How to Perfect Zucchini Brownies
To achieve the best zucchini brownies, consider these helpful tips that ensure each bite is moist and delicious.
- Use Fresh Zucchini: Freshly shredded zucchini provides the best moisture content. Avoid using pre-packaged shredded zucchini.
- Do Not Drain Zucchini: Keep all the moisture from the zucchini in your batter for rich and fudgy brownies.
- Check Baking Time: Ovens vary, so start checking your brownies at 25 minutes. They are done when a toothpick comes out with crumbs rather than wet batter.
- Let Cool Before Cutting: Allowing your brownies to cool completely helps them set up nicely, making cutting easier without falling apart.
Best Side Dishes for Zucchini Brownies
While zucchini brownies are delicious on their own, pairing them with complementary side dishes can enhance your dessert experience. Here are some great options:
- Fresh Fruit Salad: A mix of seasonal fruits provides a refreshing contrast to the rich brownies.
- Yogurt Parfait: Layer yogurt with granola and berries for a light side that balances out the sweetness.
- Cheese Platter: A selection of cheeses offers savory flavors that contrast beautifully with the sweet brownies.
- Nut Mix: A bowl of mixed nuts adds crunch and healthy fats, perfect for snacking alongside your dessert.
- Coffee or Espresso: A strong cup of coffee pairs wonderfully with chocolate desserts, enhancing the overall flavor experience.
- Herbal Tea: For a lighter option, herbal tea can cleanse the palate after enjoying rich zucchini brownies.
Common Mistakes to Avoid
When making Zucchini Brownies, there are common pitfalls that can affect the final product. Here are some mistakes to watch out for:
- Over-draining the zucchini: Removing too much moisture from the zucchini can lead to dry brownies. Use finely shredded zucchini and do not drain it.
- Skipping the resting time: Not allowing the batter to rest can prevent it from achieving the right texture. Let the mixture sit for a few minutes before adding chocolate chunks.
- Not measuring ingredients accurately: Using incorrect measurements can throw off the balance of wet and dry ingredients. Always use a kitchen scale or proper measuring cups.
- Baking at the wrong temperature: An oven that is too hot or too cold can result in uneven baking. Use an oven thermometer to ensure accurate temperatures.
- Ignoring toothpick test: Relying solely on baking time can lead to undercooked or overcooked brownies. Check readiness with a toothpick; it should come out with moist crumbs.
