Ingredients You’ll Need
- 3 tbsp cocoa powder: This adds depth to the chocolate flavor. Use unsweetened cocoa powder for best results.
- 1/4 cup butter, melted: This gives a luscious richness to the batter. You can substitute with coconut oil for a dairy-free version.
- 2 cups powdered sugar: To create a smooth frosting, powdered sugar is a must. You can’t use granulated sugar here since it won’t dissolve well.
- 1/4 cup milk: Whole milk keeps the frosting creamy; almond milk works well for a dairy-free version.
- 1 tbsp vanilla extract: The vanilla enhances the overall flavor—opt for pure vanilla extract for the best results.
- 2 cups all-purpose flour: This forms the base of the brownies. You can substitute with a gluten-free blend if needed.
- 1/2 cup cocoa powder: This is the star ingredient that packs the chocolate punch!
- 1 1/2 tsp baking soda: This helps the brownies rise and become perfectly fluffy.
- 1/2 cup canola oil: It makes the brownies tender; you could experiment with other oils like sunflower or even melted coconut oil.
- 1 1/2 cups sugar: Granulated sugar sweetens the batter and helps create that delightful crust on top.
- 2 tsp vanilla extract: A double dose of vanilla ensures your brownies are bursting with flavor.
- 2 cups zucchini, shredded: Here’s the secret ingredient that keeps your brownies moist—make sure to squeeze out excess water from the zucchini after shredding.
How to Make Best Zucchini Brownie Recipe Ever
- Preheat the Oven: Set your oven to 350°F (175°C) and prepare a 9 x 13 glass pan by spraying it with cooking spray. This ensures your brownies won’t stick and makes for easy cleanup.
- Prep Your Zucchini: Shred 2 cups of fresh zucchini using a grater. It’s important to squeeze out any excess moisture using a clean kitchen towel—it’ll help your brownies not become too soggy.
- Mix Dry Ingredients: In one bowl, whisk together 2 cups of all-purpose flour, 1/2 cup of cocoa powder, and 1 1/2 teaspoons of baking soda. Set this aside as it’s important for the fluffiness of your brownies.
- Blend Wet Ingredients: In a separate large bowl, beat together 1/2 cup of canola oil, 1 1/2 cups of granulated sugar, and 2 teaspoons of vanilla extract until well combined.
- Combine Ingredients: Gradually add the dry mixture from step 3 into the wet mixture, stirring until you achieve a smooth batter. Then, gently fold in your prepared shredded zucchini to incorporate it evenly throughout the mixture.
- Bake: Pour the brownie batter into the prepared pan, smoothing out the top. Bake for about 25 minutes. You’ll know they’re done when the edges are set and the center springs back lightly when touched. Do the toothpick test—insert one in the center, and it should come out with a few moist crumbs, not wet batter.
- Cool Down: Allow the brownies to cool completely in the pan on a wire rack while you prepare the frosting.
- Make the Frosting: In a medium bowl, mix together 3 tablespoons of cocoa powder, 1/4 cup of melted butter, and 2 cups of powdered sugar. Gradually add in 1/4 cup of milk and 1 tablespoon of vanilla extract. Beat the mixture until smooth and spreadable.
- Frost Your Brownies: Once cooled, spread the frosting generously over the brownies using a spatula, cut them into squares, and serve. Enjoy this indulgent treat!
Storing & Reheating
These brownies can be stored at room temperature in an airtight container for up to 3 days. For longer freshness, refrigerate them for up to a week in a sealed container. If you want to freeze, wrap individual brownies tightly in plastic wrap and store in a freezer-safe container for up to 3 months. When you’re ready to enjoy, simply thaw them at room temperature or pop them in the microwave for about 15-20 seconds to refresh the texture and flavor.
Chef’s Helpful Tips
- Avoid using too much zucchini, as excess moisture might make your brownies too wet. Always squeeze out the liquid!
- If you’re using coconut oil as a substitute for butter, make sure it’s melted and slightly cooled down before adding it to your batter.
- Always allow your brownies to cool completely before frosting; this prevents the frosting from melting away and makes for a neater presentation.
- Want a richer chocolaty flavor? Consider adding some chocolate chips into the batter before baking for added excitement.

Recipe FAQs
Can I omit the zucchini from the recipe?
Absolutely, but keep in mind it may change the texture. You could replace it with applesauce for added moisture or swap in mashed bananas for a different flavor profile.
How do I know when my brownies are done baking?
The perfect brownie will spring back slightly when touched, and a toothpick should come out with a few moist crumbs attached rather than completely clean.
How can I make these brownies gluten-free?
You can substitute the all-purpose flour with a certified gluten-free flour blend, which typically works well in baking. Just be sure to check that all other ingredients are gluten-free as well.
Can I use less sugar in the recipe?
You can reduce the sugar if you prefer less sweetness, but keep in mind that it might impact the overall texture and moistness of the brownies as sugar affects baking chemistry.
