Total time: 50 min
Ingredients: 1 cup all purpose flour; 1/2 cup unsweetened cocoa powder; 3/4 cup granulated sugar; 1/4 cup brown sugar, packed; 1 teaspoon baking powder; 1/2 teaspoon fine sea salt; 1 1/2 cups shredded zucchini, lightly packed; 1/3 cup neutral oil (such as avocado, grapeseed, or light olive oil); 1/4 cup dairy free milk (such as almond or oat milk); 2 teaspoons vanilla extract; 1/2–3/4 cup vegan chocolate chips; 1/3 cup chopped walnuts or pecans

Vegan Zucchini Brownies Recipe tastes ultra fudgy, rich, and chocolatey, with little flecks of zucchini that melt into the batter and keep everything moist. It works perfectly for busy families, chocolate lovers who want a lighter treat, or anyone who needs a dairy free, egg free dessert in about 45 minutes. I tested this version on my skeptical Midwestern relatives, and they asked for seconds before I told them about the vegetables.

Why Make This Vegan Zucchini Brownies Recipe at Home

Homemade vegan zucchini brownies taste fresher, richer, and more chocolatey than most store bought mixes. You control the sweetness, the oil, and the amount of chocolate, so the brownies can lean extra fudgy or a little more cakey.

You also sneak in a solid amount of zucchini without anyone noticing, which feels like a tiny parenting or adulting victory. The recipe uses simple pantry ingredients, so you probably own most of them already.

Ingredients You Need

Here is everything you need to make this Vegan Zucchini Brownies Recipe.

Dry ingredients

All purpose flour, 1 cup (120 g)
- Use unbleached if possible.
- Whole wheat pastry flour works too, but use 2 tablespoons less so the brownies stay tender.
Cocoa powder, 1/2 cup (40 g), unsweetened, natural or Dutch process
- I like Ghirardelli or Hershey's Special Dark for a deep chocolate flavor.
Granulated sugar, 3/4 cup
- Organic cane sugar usually counts as vegan in the US, but check the label.
- Coconut sugar works, but the brownies turn slightly more dense and less shiny.
Brown sugar, 1/4 cup, packed
- This adds moisture and a hint of caramel flavor.
- Use light or dark brown sugar.
Baking powder, 1 teaspoon
Fine sea salt, 1/2 teaspoon

Wet ingredients

Shredded zucchini, 1 1/2 cups, lightly packed
- About 1 medium to large zucchini.
- Do not peel it; the skin adds color and nutrients.
- Pat very lightly with a towel if it drips, but keep most of the moisture for fudgy texture.
Neutral oil, 1/3 cup
- Use avocado, grapeseed, or light olive oil.
- Melted coconut oil works too, but cool it slightly so it does not seize the chocolate.
Dairy free milk, 1/4 cup
- I like unsweetened almond or oat milk.
- Use what you have: soy, cashew, or even pea milk.
Vanilla extract, 2 teaspoons

Mix ins

Vegan chocolate chips, 1/2 to 3/4 cup
- Enjoy Life, Trader Joe's, or Costco Kirkland semi sweet chips usually stay dairy free, but check ingredients.
- Use mini chips if you want more even chocolate pockets.
Optional: chopped walnuts or pecans, 1/3 cup
- Toast them lightly in a dry pan for extra flavor.

Equipment

8 inch square baking pan
- Line it with parchment and lightly grease it so the brownies lift out easily.
Medium and large mixing bowls
Whisk and rubber spatula
Box grater or food processor with shredding disc for the zucchini
Measuring cups and spoons
Cooling rack
Sharp knife for slicing

Tips & Mistakes

Squeeze the zucchini only if it drips like crazy; keep most moisture so the brownies stay fudgy.
Measure flour by spooning it into the cup and leveling; packed flour makes dry, cakey brownies.
Whisk dry ingredients well so the baking powder and salt distribute evenly.
Do not overmix once you add the flour; stir just until no dry streaks remain.
Fold chocolate chips in gently so they do not sink to the bottom.
Line the pan with parchment so the brownies lift out cleanly and slice neatly.
Bake until the top looks set and a toothpick comes out with moist crumbs, not wet batter.
Cool completely before slicing; warm brownies taste great but cut into a mess.
Store leftovers in an airtight container so they stay moist and chewy.
Chill the batter in the pan for 10 minutes before baking if your kitchen runs hot; this helps a shinier top.

How to Make Vegan Zucchini Brownies Recipe

Step 1: Prep the pan and oven

Preheat your oven to 350°F (175°C).
Line an 8 inch square pan with parchment, leaving a little overhang as handles, and lightly grease the parchment.
Set the pan aside while you mix the batter.

Step 2: Shred the zucchini

Wash and dry the zucchini.
Grate it on the medium holes of a box grater or use a food processor shredding disc.
Lightly fluff the shreds with your fingers and check for excess liquid; if it drips a lot, pat once or twice with a clean towel, but do not wring it dry.

Step 3: Mix the dry ingredients

In a medium bowl, whisk together the flour, cocoa powder, granulated sugar, brown sugar, baking powder, and salt.
Break up any cocoa or brown sugar clumps with the whisk.
Set the bowl aside.

Step 4: Mix the wet ingredients

In a large bowl, add the shredded zucchini, oil, dairy free milk, and vanilla extract.
Stir until the zucchini coats evenly with the liquid ingredients.
The mixture looks loose and slightly chunky, which works perfectly.

Step 5: Combine wet and dry

Pour the dry mixture into the bowl with the zucchini mixture.
Use a rubber spatula to fold everything together until no dry flour streaks remain.
Scrape the bottom and sides of the bowl so you catch any hidden pockets of flour.

Step 6: Add chocolate chips and nuts

Fold in the vegan chocolate chips and optional nuts.
Distribute them evenly so each brownie square gets some chocolate and crunch.
If the batter looks very thick, drizzle in 1 to 2 extra tablespoons of dairy free milk and fold again.

Step 7: Bake

Spread the batter into the prepared pan and smooth the top with your spatula.
Sprinkle a few extra chocolate chips on top if you want a bakery style look.
Bake for 25 to 30 minutes, until the top looks set and a toothpick inserted near the center comes out with moist crumbs, not wet batter.

Step 8: Cool and slice

Place the pan on a cooling rack and let the brownies cool at least 30 to 45 minutes.
Lift the brownies out using the parchment handles.
Slice into 9 large squares or 16 smaller ones, wiping the knife between cuts for clean edges.

Variations I've Tried

I swap half the chocolate chips for chopped walnuts or pecans when I want a little crunch and a more classic brownie vibe.
I add 1 teaspoon instant espresso powder to the dry ingredients when I want deeper chocolate flavor; it does not make the brownies taste like coffee.
I stir in 1/3 cup shredded coconut and use coconut oil for a chocolate coconut version that tastes like a candy bar.
I also tried a gluten free version with a 1 to 1 gluten free baking blend, and it worked nicely, though it baked a few minutes faster, so I started checking at 22 minutes.

How to Serve Vegan Zucchini Brownies Recipe

Serve these vegan zucchini brownies slightly warm or at room temperature so the chocolate chips stay soft and melty.
Top a square with a scoop of dairy free vanilla ice cream or coconut whipped cream for a full dessert plate.
Pair a brownie with a cold glass of oat milk, almond milk, or your favorite non dairy milk for an afternoon snack.
Pack them in lunchboxes, picnic baskets, or road trip containers, since they hold their shape and taste even better the next day.

How to store

Counter: Store sliced brownies in an airtight container at room temperature for up to 2 days.
Fridge: Keep in a sealed container for 4 to 5 days; place parchment between layers to prevent sticking.
Freezer: Wrap individual squares in plastic or parchment, place in a freezer bag, and freeze for up to 2 months.
Reheat: Warm a brownie in the microwave for 10 to 15 seconds or in a 300°F oven for 5 to 8 minutes until just soft and slightly gooey again.
