Ingredients

For the Brownies:

• ½ cup vegetable oil

• 1 cup granulated sugar

• ½ cup packed light brown sugar

• 2 teaspoons pure vanilla extract

• 2 cups all-purpose flour

• ½ cup dark chocolate unsweetened cocoa powder

• 1 ½ teaspoons baking soda

• 1 teaspoon kosher salt

• 2 ½ cups finely shredded zucchini

For the Frosting:

• ¼ cup unsalted butter, melted

• 5 tablespoons dark chocolate unsweetened cocoa powder

• 2 cups powdered sugar

• 6 tablespoons heavy whipping cream

• ½ teaspoon vanilla extract

Step-by-Step: How to Make Chocolate Zucchini Brownies

1. Prep the Pan – Preheat oven to 350°F (175°C). Line a 13×9-inch baking dish with parchment paper, leaving an overhang for easy removal.

2. Mix the Wet Ingredients – In a large mixing bowl, whisk together vegetable oil, granulated sugar, light brown sugar, and vanilla until smooth.

3. Add Dry Ingredients – Stir in the flour, cocoa powder, baking soda, and salt. The batter will appear very dry at this stage—don’t worry!

4. Incorporate Zucchini – Fold in shredded zucchini. Should the batter seem dry, let it rest for 10 minutes to allow the zucchini to naturally release its moisture.

5. Bake the Brownies – Pour the batter evenly into the prepared pan and bake for 25–30 minutes, or until a toothpick inserted in the center emerges with just a few moist crumbs.

6. Cool Completely – Allow brownies to cool fully before frosting to avoid melting the topping.

7. Make the Frosting – Prepare the frosting by whisking melted butter and cocoa powder together in a medium bowl until silky smooth. Gradually add powdered sugar, alternating with heavy cream, whisking until fluffy. Stir in vanilla.

8. Frost & Serve – Once cooled, generously frost the brownies, cut into squares, and savor each indulgent bite.

Helpful Tips

• Don’t Skip the Resting Step – This allows zucchini moisture to fully hydrate the batter for a moist crumb.

• Use a Plastic Knife for Cutting – Prevents crumbling and ensures clean, even slices.

• Cool Before Frosting – Always let brownies cool completely before frosting to keep the topping from melting or sliding off.

• Garden Fresh Zucchini – If your zucchini is extra watery, lightly blot it before adding to the batter.

• Boost the Chocolate – Stir in chocolate chips for an even more indulgent treat.

Substitutions and Variations

• Gluten-Free Version – Swap all-purpose flour for a gluten-free baking blend.

• Vegan Option – Use coconut oil instead of butter, plant-based cream, and dairy-free chocolate.

• Nutty Crunch – Fold in chopped walnuts or pecans for texture.

• Spiced Twist – Add ½ teaspoon cinnamon for a warm, cozy note.

• Mini Brownies – For mini brownie bites, bake the batter in a mini muffin tin for a fun, snackable twist.

Storage Instructions

• Room Temperature – Store at room temperature in an airtight container for up to 4–5 days of freshness.

• Refrigeration – Refrigerate for up to 1 week, then bring to room temperature before serving for the best flavor and texture.

• Freezing – Wrap individually and store in a freezer-safe bag for up to 3 months. Thaw brownies overnight in the refrigerator or let them come to room temperature before serving.

Frequently Asked Questions About Chocolate Zucchini Brownies

1. Will I taste the zucchini in these brownies?
In baked goods, zucchini blends seamlessly—adding moisture and a soft crumb without altering the flavor.

3. Can I use frozen zucchini?
Yes, but thaw completely and drain excess moisture before adding to the batter.

4. What’s the best way to tell if brownies are fully baked?
Insert a toothpick into the center—some moist crumbs are okay, but there should be no wet batter.

Absolutely! They’re still rich and delicious unfrosted, but the frosting does add extra decadence.
