How to Make It

Follow these simple steps to create your brownies.

Preheat

Preheat the oven to 350°F (175°C). Grease and line a 9×13-inch baking pan with parchment paper for easy removal.

Mix wet ingredients

In a large bowl, whisk together the oil, sugar, eggs, and vanilla until smooth and well combined.

Combine dry ingredients

In another bowl, sift together the flour, cocoa powder, baking soda, and salt.

Bring it together

Gradually add the dry mixture to the wet mixture, alternating with the milk. Stir until just combined (do not overmix).

Add zucchini

Gently fold in the grated zucchini, followed by the chocolate chips. The batter will be thick at first but will loosen as the zucchini releases moisture.

Bake

Spread the batter evenly into the prepared pan. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs.

Cool & serve

Allow the brownies to cool in the pan for at least 20 minutes before slicing into squares.

How to Store It

Fridge: Store in an airtight container for up to 5 days.
Freezer: Yes, for up to 3 months; wrap tightly to prevent freezer burn.
Reheat: Microwave on medium power for 10-15 seconds.

Tips for Best Results

• Use a box grater for finely grating the zucchini to ensure even moisture distribution.
• Let the brownies cool completely before slicing to avoid crumbling.
• Adjust baking time slightly if you prefer a fudgier texture.
• Try adding nuts for added crunch and flavor.

Serving Suggestions

• Serve warm with a scoop of vanilla ice cream.
• Pair with fresh berries for a refreshing contrast.
• Enjoy with a glass of cold milk or a cup of coffee.
