Ingredients
- 1 1/2 cups all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1/2 cup granulated sugar
- 1/2 cup brown sugar, packed
- 1/4 cup vegetable oil
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup shredded zucchini (about 1 medium zucchini)
- 1/2 cup mini chocolate chips
- 1/2 cup semisweet chocolate chips
- 1/4 cup milk (or dairy-free alternative)
- 2 tablespoons butter, melted
Instructions
To create these scrumptious Double-Chocolate Zucchini Brownies, start by preheating your oven to 350°F (175°C). Prepare a 9×9-inch baking pan by greasing it lightly or lining it with parchment paper for easy removal later. This step is essential for achieving perfectly baked brownies without any sticking.
In a large mixing bowl, whisk together the all-purpose flour, cocoa powder, baking powder, and salt until well combined. This will allow all the dry ingredients to be evenly distributed, contributing to the overall texture of the brownies.
Next, grab another bowl to mix the sugars with the wet ingredients. Combine the granulated sugar, packed brown sugar, and vegetable oil. Add the eggs and vanilla extract, then mix everything well until the mixture is smooth and creamy. This blend of sugars adds to the richness of the brownies while the oil ensures moisture.
Now, it’s time to incorporate the star ingredient: zucchini. Stir in the shredded zucchini, mixing until it’s fully combined with the wet ingredients. The zucchini adds a layer of moisture while keeping the brownies fudgy, so don’t rush this step!
Carefully add the dry ingredients to the wet mixture. Use a spatula or wooden spoon to stir just until the ingredients are combined. Remember, be cautious not to overmix; a few lumps are perfectly fine. This keeps your brownies tender and melt-in-your-mouth good.
Once integrated, fold in the mini chocolate chips and semisweet chocolate chips. This adds extra chocolate flavor and fun bursts of sweetness throughout every bite!
Pour the brownie batter into the prepared baking pan, spreading it evenly with the spatula. Make sure to smooth out the top for even baking.
Then, slide the pan into your preheated oven and bake for 25-30 minutes. The brownies are done when a toothpick inserted in the center comes out with a few moist crumbs attached but no wet batter. Once baked, remove them from the oven and allow them to cool completely in the pan. This cooling step is crucial as it helps set the texture.
As a finishing touch, drizzle some melted butter mixed with a bit of milk over the top of the cooled brownies for a glossy and tempting chocolate finish before cutting them into squares and serving.

Variations
While Isabella’s Double-Chocolate Zucchini Brownies are already perfect as they are, there are plenty of delicious variations you can try:
- Nutty Addition: Add some chopped walnuts or pecans to the batter for a crunchy texture that contrasts with the fudgy brownies.
- Sugar Substitutes: For those looking to reduce sugar, try using coconut sugar or a natural sweetener like maple syrup.
- Spicy Kick: Incorporate a pinch of cayenne pepper or chili powder to the batter for a surprising warm flavor that pairs wonderfully with chocolate.
- Dairy-Free Version: Substitute all dairy ingredients like butter, milk, and chocolate chips with dairy-free alternatives to cater to lactose-intolerant friends or family.
Cooking Notes
Here are some handy cooking notes to help you achieve your best Double-Chocolate Zucchini Brownies:
- Ensure your zucchini is well-drained: If your zucchini is too watery, it may affect the texture of your brownies. After shredding, consider squeezing it in a clean kitchen towel to remove excess moisture.
- Storage: These brownies keep well in an airtight container for up to a week at room temperature or in the fridge for extended freshness.
- Chocolate Chips: Experiment with the type of chocolate chips you use. Try using white chocolate chips for a different flavor profile.
- Serving Size: If you love chocolate, don’t be shy! These brownies can easily be cut into smaller or larger squares taking into account each person’s preferences.
Serving Suggestions
These delicious brownies are perfect on their own, but here are a few serving suggestions to elevate your dessert experience:
- Serve warm with a scoop of vanilla ice cream on top.
- Drizzle with homemade chocolate sauce or caramel for an added layer of sweetness.
- Dust with powdered sugar just before serving for an elegant finish.

Tips
- For extra fudgy brownies, slightly underbake them.
- If you’re uncertain about your zucchini measurement, one medium zucchini typically yields about a cup when shredded.
- Before slicing the brownies, let them cool completely for clean cuts.
- Consider using a plastic knife to prevent crumbling when cutting.
