Ingredients
- 2 cups all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1 1/2 teaspoons baking soda
- 1 teaspoon salt
- 1/2 cup vegetable oil
- 1 1/2 cups granulated sugar
- 2 teaspoons vanilla extract
- 2 cups grated zucchini
- 1/2 cup chopped walnuts or chocolate chips (optional)
For the Frosting (optional):
- 1/4 cup butter (melted)
- 1/4 cup unsweetened cocoa powder
- 2 cups powdered sugar
- 1/4 cup milk
- 1/2 teaspoon vanilla extract
Directions
- Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan to prevent sticking.
- In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set aside.
- In a large mixing bowl, combine the vegetable oil, sugar, and vanilla extract. Stir in the grated zucchini until everything is thoroughly mixed.
- Gradually add the dry ingredients into the zucchini mixture, stirring just until combined. The batter may seem thick—don’t worry! The zucchini will release moisture during baking.
- If you like, fold in chopped walnuts or chocolate chips for extra texture and flavor.
- Spread the batter evenly into your prepared baking pan, smoothing the top with a spatula.
- Bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs.
- While the brownies cool in their pan, prepare the frosting if you want to make them extra decadent. In a medium bowl, whisk together the melted butter and cocoa powder. Gradually add powdered sugar and milk, mixing until the frosting reaches a smooth and creamy consistency. Stir in vanilla extract.
- Once the brownies are completely cool, spread the frosting evenly over the top.
- Cut into squares and serve. Enjoy!
What to Serve With
Zucchini Brownies are wonderful all on their own, but if you’re looking for a special twist, try serving them with a scoop of vanilla ice cream or a dollop of whipped cream. Pair with a glass of cold milk, a creamy latte, or even a fruity summer smoothie for a well-rounded treat. If you’re serving them at a party, a platter of fresh berries or sliced fruit will brighten up the dessert table and complement the chocolate’s richness.
Top Tips for Perfecting
- For the fudgiest brownies, do not squeeze the moisture from the zucchini—its natural juiciness is key!
- Don’t overmix—the more you stir, the tougher your brownies will be. Mix until just combined for the softest texture.
- If you’re out of vegetable oil, melted coconut oil or canola oil works perfectly.
- Love extra chocolate? Use mini chocolate chips for an even richer bite.
- Keep an eye on baking time: err on the side of slightly underbaked for gooier brownies, and avoid overbaking, which can dry them out.
Storing and Reheating Tips
To store leftover brownies, let them cool completely and then transfer to an airtight container. They’ll stay fresh at room temperature for up to 3 days, or in the refrigerator for up to a week. For longer storage, wrap individual squares and freeze for up to 3 months; defrost at room temperature before serving. To enjoy that fresh-from-the-oven taste, zap refrigerated brownies in the microwave for 10-15 seconds. Frosted brownies may need to be chilled in warm weather to keep the topping from getting messy.
FAQs
Can I really not taste the zucchini in these brownies?
Nope! The zucchini gives moisture and a soft texture, but you won’t taste it at all. Even picky eaters will have no idea.
Can I make this recipe gluten-free?
Absolutely. Swap out the all-purpose flour for your favorite gluten-free blend (1:1 baking mixes work best).
Do I need to peel the zucchini before grating?
Not necessary—the peel adds subtle flecks of color and nutrients. Just wash well and grate, no peeling required.
Should I squeeze the water out of the grated zucchini?
For this recipe, don’t squeeze out the liquid—zucchini’s moisture is what keeps the brownies ultra-fudgy.
Can I skip the frosting?
Of course! The brownies are delicious on their own, but the frosting adds a layer of indulgence—totally up to you.
