What You’ll Need
For the Brownies:
- 1 1/2 cups zucchini (finely shredded, about 1 medium zucchini)
- 1/2 cup ground flaxseed meal (mixed with 6 tablespoons water)
- 1/2 cup coconut oil (melted and cooled slightly)
- 3/4 cup brown sugar (packed)
- 1/2 cup granulated sugar
- 2 teaspoons vanilla extract
- 1 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1/4 teaspoon cinnamon (optional but recommended)
- 3/4 cup vegan chocolate chips (divided)
- 1/4 cup non-dairy milk (almond, oat, or soy)
Substitution Notes:
- Ground flaxseed meal → 3 tablespoons aquafaba or commercial vegan egg replacer
- Coconut oil → Vegan butter or neutral vegetable oil
- Brown sugar → Coconut sugar or additional granulated sugar
- All-purpose flour → Whole wheat pastry flour or gluten-free flour blend
- Non-dairy milk → Any plant-based milk works perfectly
Step-by-Step Directions
- Preheat your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper, leaving overhang for easy removal. Lightly grease the parchment with cooking spray or a bit of coconut oil.
- Prepare your flax eggs. In a small bowl, mix the ground flaxseed meal with 6 tablespoons of water. Stir well and let sit for 10-15 minutes until it becomes gel-like and thickened—this is your vegan egg replacement.
- Prepare the zucchini. Wash and trim the zucchini, then shred it finely using a box grater or food processor. You don’t need to peel it—the skin adds extra nutrition and won’t be noticeable in the finished brownies. Gently squeeze the shredded zucchini with your hands or a clean kitchen towel to remove excess moisture, but don’t worry about getting it completely dry.
Zucchini tip: The moisture in zucchini varies by season and size. Summer zucchini tends to be more watery, so give it an extra gentle squeeze to prevent soggy brownies.
- Mix the wet ingredients. In a large mixing bowl, whisk together the melted coconut oil, brown sugar, and granulated sugar until smooth. Add the prepared flax eggs, vanilla extract, and non-dairy milk, mixing until well combined. The mixture should be smooth and slightly glossy.
- Combine the dry ingredients. In a separate bowl, whisk together flour, cocoa powder, baking soda, salt, and cinnamon until no lumps remain. This ensures your brownies have an even chocolate flavor throughout.
- Bring it all together. Add the dry ingredients to the wet mixture, stirring gently just until combined. Fold in the shredded zucchini and 1/2 cup of chocolate chips, mixing until evenly distributed. The batter will be thick and chocolatey with visible flecks of green zucchini.
Mixing tip: Don’t overmix once you add the flour—this can lead to tough brownies. A few small lumps are perfectly fine!
- Transfer and top. Spread the batter evenly in your prepared pan using an offset spatula. Sprinkle the remaining 1/4 cup chocolate chips on top for an extra indulgent finish that looks bakery-professional.
- Bake to perfection. Bake for 28-32 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs clinging to it. The top should look set and have a slight matte finish. Remember, slightly underdone is better than overbaked when it comes to fudgy brownies!
- Cool completely. Let the brownies cool in the pan for at least 45 minutes—this is crucial for clean cuts and the perfect fudgy texture. Use the parchment overhang to lift out the brownies, then cut into 16 squares with a sharp knife.
How to Serve
These delicious vegan zucchini brownies are incredibly versatile and perfect for any occasion:
Everyday Treats: Serve at room temperature with a cold glass of your favorite plant-based milk. The natural sweetness pairs beautifully with unsweetened almond or oat milk.
Special Occasions: Dust with powdered sugar and serve with fresh berries for an elegant dessert. A dollop of coconut whipped cream takes these brownies from delicious to absolutely divine.
On-the-Go: These brownies are perfect for lunch boxes, picnics, or afternoon snacks. They’re sturdy enough to travel well and won’t fall apart in your bag.
Breakfast Treat: Yes, really! With hidden vegetables and less sugar than many muffins, a small square with your morning coffee isn’t the worst way to start your day.
Expert Tips for Success
Zucchini Selection: Choose medium-sized zucchini that feel heavy for their size—they have the best flavor and texture for baking. Avoid oversized zucchini, which can be watery and have large seeds.
Storage Secrets: Store covered at room temperature for up to 4 days, or refrigerate for up to a week. These actually improve after a day or two as the flavors meld together. For longer storage, wrap individual squares and freeze for up to 3 months.
Texture Perfection: The key to ultra-fudgy brownies is not overbaking. They’ll continue to cook slightly after removing from the oven, so err on the side of caution. The center should still look slightly soft when you remove them.
Seasonal Variations: In fall, add 1/4 teaspoon each of nutmeg and ginger along with the cinnamon for warm spice notes. In summer, fold in 1/4 cup of mini vegan white chocolate chips for extra indulgence.
Make-ahead magic: The batter can be prepared and stored in the refrigerator for up to 24 hours before baking. This actually improves the flavor as the cocoa has time to bloom. Just bring to room temperature before baking and add 2-3 extra minutes to the baking time.
Nutritional Boost: For extra nutrition, replace 1/4 cup of the flour with almond meal or add 2 tablespoons of chia seeds to the batter. Your family will never know they’re eating something so healthy!
Common Questions
Can you actually taste the zucchini in these brownies?
Not at all! The zucchini provides moisture and a tender texture but completely disappears flavor-wise into the rich chocolate. Even zucchini skeptics will be converted after one bite.
My brownies seem too moist—what happened?
This usually happens when the zucchini wasn’t drained well enough, or if you used a particularly watery zucchini. Next time, squeeze the shredded zucchini more thoroughly, and consider adding an extra 2-3 tablespoons of flour to absorb excess moisture.
Can I use frozen zucchini?
Yes, but thaw it completely first and drain it very well. Frozen zucchini releases more water than fresh, so you’ll need to be extra diligent about removing moisture to prevent soggy brownies.
How finely should I shred the zucchini?
Use the smaller holes on your box grater—you want pieces about the size of rice grains. Too large and you’ll have chunks of zucchini in your brownies; too fine and it becomes mushy during baking.
Can I make these oil-free?
You can substitute the coconut oil with unsweetened applesauce or mashed banana, but the texture will be more cake-like than fudgy. Use 1/4 cup of applesauce plus 2 extra tablespoons of non-dairy milk as your replacement.
Do I need to peel the zucchini?
Nope! The skin is packed with nutrients and won’t be noticeable in the finished brownies. Just wash the zucchini well and trim off the ends before shredding.
