Ingredients You’ll Need

3 tbsp cocoa powder: This adds depth to the chocolate flavor. Use high-quality cocoa for the best results.
1/4 cup butter, melted: Adds richness and moisture. You can substitute with coconut oil if you’re looking for a dairy-free option.
2 cups powdered sugar: This sweetens the frosting just right, providing a smooth and creamy finish.
1/4 cup milk: Adds moisture to the frosting. You can use almond milk or oat milk as a substitute.
1 tbsp vanilla extract: A must-have for enhancing the overall flavor profile. Use pure vanilla extract for the best taste.
2 cups flour: All-purpose flour provides structure. For a gluten-free version, try using a 1:1 gluten-free flour blend.
1/2 cup cocoa powder: This is pivotal for the brownie base, giving it that rich chocolate kick.
1 1/2 tsp baking soda: Helps the brownies rise and gives them a lovely soft texture.
1/2 cup canola oil: Adds moisture and prevents the brownies from drying out. You may substitute with vegetable oil if desired.
1 1/2 cups sugar: White granulated sugar provides sweetness and texture. Coconut sugar can be used for a healthier option.
2 tsp vanilla extract: Enhances the brownie flavor; trust me, it makes a difference.
2 cups zucchini, shredded: The star of the show! Zucchini keeps the brownies moist and adds hidden nutrition.

How to Make Best Zucchini Brownie Recipe Ever

Preheat the Oven: Start by heating your oven to 350°F (175°C). This ensures that your brownies bake evenly from the start. Grease a 9 x 13-inch glass pan with non-stick spray and set aside.
Prepare the Zucchini: Grate enough zucchini to yield 2 cups. Make sure to pat it dry with a clean towel to remove excess moisture; this will help keep your brownies from becoming too soggy.
Mix Dry Ingredients: In a medium bowl, whisk together 2 cups of flour, 1/2 cup of cocoa powder, and 1 1/2 tsp baking soda. This helps to evenly distribute the leavening agent and cocoa throughout the brownie batter. Set aside.
Combine Wet Ingredients: In another large mixing bowl, combine 1/2 cup canola oil, 1 1/2 cups sugar, and 2 tsp vanilla extract. Mix until well combined.
Combine Dry with Wet: Gradually add the flour mixture to the wet ingredients, stirring until just combined. Avoid overmixing; this keeps the brownies tender and chewy.
Fold in the Zucchini: Gently fold the shredded zucchini into the batter with a spatula until it is well incorporated. The zucchini will add moisture and a slight sweetness.
Bake: Pour the batter into the prepared pan and spread evenly. Bake for 25 minutes, or until the edges appear firm, and the middle springs back when lightly touched. Let them cool in the pan for a few minutes before transferring to a wire rack.
Make the Frosting: For the decadent frosting, combine 3 tbsp cocoa powder, 1/4 cup melted butter, and 2 cups powdered sugar in a mixing bowl. Gradually stir in 1/4 cup milk and 1 tbsp vanilla extract. Mix until smooth and creamy.
Frosting the Brownies: Once the brownies have cooled completely, spread the frosting generously over the top. Cut into squares and serve!

Storing & Reheating

Store any leftover brownies in an airtight container at room temperature for up to 3 days. You can refrigerate them for up to a week if you prefer a chilled treat. For longer storage, freeze them for up to 3 months. Wrap them tightly in plastic wrap, then place in a freezer-safe container. When ready to enjoy, let them thaw at room temperature or use the microwave for about 15-20 seconds. Note that the texture may change slightly after freezing, but they’ll still be delicious!

Chef’s Helpful Tips

Make sure you’re using finely shredded zucchini to avoid chunks in your brownies that could disrupt the fudgy texture.
If you find your batter is too thick, you can add a tablespoon of water to loosen it up.
Remember that all ovens can vary, so start checking for doneness a few minutes before the suggested baking time.
Feel free to mix in some chocolate chips or nuts into the batter if you want to add an extra layer of flavor and texture.
If you’re short on time, these brownies can also be enjoyed without frosting for a slightly less sweet treat!

You’ll love how easy and delicious these brownies are. They pack so much flavor and will disappear quickly from the platter! Don’t hesitate to try different toppings or mix-ins to make this your own.

Recipe FAQs

Can I make these gluten-free?

Absolutely! Simply substitute the all-purpose flour with a 1:1 gluten-free flour blend. This will ensure your brownies turn out perfectly without any gluten.

Can I use yellow squash instead of zucchini?

Yes, you can use yellow squash as a substitute. The flavor may be slightly different, but the texture will still hold up well in the brownies.

How can I tell when the brownies are done?

The best way to check for doneness is to gently touch the center of the brownies. If it springs back, they’re ready! You can also use a toothpick; if it comes out with just a few crumbs, your brownies are good to go.

What ice cream flavor pairs well with these brownies?

Pairing these brownies with vanilla ice cream is classic and delightful! The cold creaminess complements the fudgy brownies beautifully. Enjoy the contrast for a truly indulgent dessert!
