I’m Obsessed With These Fudgy Chocolate Zucchini Brownies

Have you ever tried sneaking veggies into dessert and actually loved the result? I’m obsessed with these fudgy chocolate zucchini brownies that bring together the best of both worlds: rich chocolate and moist, hidden zucchini. These chocolate zucchini brownies are the perfect way to enjoy a decadent treat that feels just a little bit better for you.

The subtle addition of zucchini adds moisture without overpowering the chocolate flavor, creating a brownie that’s as fudgy as it is tender. Whether you’re a brownie purist or a vegetable skeptic, these will win you over bite by bite.

Why I Can’t Stop Making These Cookies

• Instantly fudgy texture that melts in your mouth
• Moisture-packed brownies with a sneaky veggie boost
• Uses pantry staples you likely have on hand
• A kid-friendly way to enjoy vegetables without any fuss
• Perfect for every season, especially when zucchini is fresh and abundant

What Type of Zucchini Should I Use?

For the best chocolate zucchini brownies, fresh zucchini is ideal. Look for firm, bright green squash without soft spots. If zucchini is in season, grab medium-sized ones around 6 to 8 inches long, as they are less watery and more flavorful. If you’re using frozen zucchini, thaw thoroughly and squeeze out excess moisture by wrapping it in a clean kitchen towel or paper towels to avoid soggy batter. Dried zucchini isn’t recommended here since it lacks the moisture that makes these brownies so luscious.

Options for Ingredient Alternatives

• Butter or neutral oil like vegetable oil can be used interchangeably; if substituting with solid coconut oil, chill the dough for 30 minutes before baking.
• Use semi-sweet chocolate chips for dark, milk, or even white chocolate, depending on your preference.
• Use dairy or plant-based milks such as almond, oat, or soy for a dairy-free treat.
• Vanilla extract can be replaced with almond or peppermint extracts for a twist.
• For extra texture or flavor, subtract some zucchini and add ½ cup dried cranberries or chopped nuts.

The Biggest Challenges While Baking

• Fold in zucchini and chocolate chips last and gently to avoid overmixing and tough brownies.
• Use softened butter rather than melted butter to create a balanced, tender crumb.
• Don’t overmix the batter; stop as soon as ingredients are incorporated for fudgy brownies.
• If the dough feels dry, add milk one tablespoon at a time until it reaches a slightly thick but scoopable consistency.
• Chill the dough for 30 minutes if using coconut oil or if you want cleaner brownie edges.

Storage & Freezing Instructions

Store cooled brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week. To freeze, layer brownies between parchment or wax paper in a freezer-safe container and freeze for up to 3 months. Let thaw at room temperature before serving. You can also freeze the dough in a log, wrapped tightly, and thaw overnight in the fridge before slicing and baking fresh brownies.

Ingredients

• 1 cup granulated sugar (200 g)
• 1/2 cup unsalted butter, softened (115 g)
• 2 large eggs
• 1 1/2 tsp vanilla extract
• 1/2 tsp salt
• 1/2 tsp baking powder
• 1/2 cup unsweetened cocoa powder (50 g)
• 1 cup all-purpose flour (120 g)
• 1 1/2 cups grated zucchini, squeezed dry (about one medium zucchini, 150 g)
• 1 csemisweet chocolate chips (170 g)
• 2 Tbsp milk, only if dough is dry (optional)

Step-by-Step Instructions

1. Preheat oven to 350°F (175°C). Grease or line an 8×8-inch (20×20 cm) square baking pan with parchment paper, leaving an overhang for easy removal.
2. In a large bowl, cream together the softened butter and sugar until fluffy and light in color.
3. Beat in the eggs one at a time, then stir in the vanilla extract until combined.
4. In a separate bowl, whisk together the cocoa powder, salt, baking powder, and flour. Slowly add this dry mixture to the butter mixture, stirring just until combined. Do not overmix.
5. Fold in the grated zucchini gently, making sure it’s well distributed but without breaking up too much. Then carefully fold in the chocolate chips last.
6. If the batter feels too dry and crumbly, mix in milk one tablespoon at a time until you reach a thick but moist batter consistency.
7. Spread the batter evenly into the prepared pan. Bake for 25–30 minutes until a toothpick inserted near the center comes out with a few moist crumbs (don’t overbake for max fudginess). Cool completely in the pan before slicing into squares.

Tips, Variations & Serving Ideas

• Add ½ cup chopped walnuts, pecans, or toasted hazelnuts for crunch.
• Sprinkle flaky sea salt on top before baking for a flavor boost.
• For extra gooey brownies, reduce baking time by 3-5 minutes.
• Serve warm with a scoop of vanilla ice cream or a drizzle of caramel sauce.
• Store leftover brownies wrapped in foil and reheat slightly to revive that fudgy texture.
• Try swapping in pumpkin puree or mashed sweet potato for a seasonal spin.
• Use mini chocolate chips or chopped baking chocolate for texture contrast.

FAQs

Can I use yellow squash instead of zucchini?
Yes, yellow squash works fine as it has a similar moisture content and mild flavor.

Do I need to peel the zucchini?
No, the skin adds color and nutrients, so wash and grate it.

Can I make these gluten-free?
Absolutely! Substitute all-purpose flour with a 1:1 gluten-free baking flour blend.

How do I know when the brownies are done?
The edges should look set, and a toothpick in the center should come out with moist crumbs, not wet batter.
