Double Chocolate Zucchini Brownies — Do This Next

Step 1: Prep Your Zucchini

Start by washing and finely grating 1 cup of zucchini. Place the grated zucchini in a clean kitchen towel or paper towels and gently squeeze out excess water. This step is crucial to avoid soggy brownies.

Step 2: Mix Wet Ingredients

In a large bowl, whisk together the granulated sugar, brown sugar, and vegetable oil until fully combined. Beat in the eggs one at a time, then stir in the vanilla extract.

Step 3: Combine Dry Ingredients

In a separate bowl, sift together the all-purpose flour, cocoa powder, baking powder, baking soda, and salt. This ensures even distribution and prevents lumps.

Step 4: Bring It All Together

Gradually add the dry ingredients into the wet mixture, folding gently until just combined. Avoid overmixing to keep brownies tender. Then fold in the grated zucchini and chocolate chips, distributing them evenly throughout the batter.

Step 5: Bake to Perfection

Preheat your oven to 350°F (175°C). Line a 9×9 inch baking pan with parchment paper or grease it well. Transfer the brownie batter into the pan, spreading it evenly. Bake for 25-30 minutes or until a toothpick inserted near the center comes out with moist crumbs.

Step 6: Cool and Serve

Allow the brownies to cool completely in the pan on a wire rack. Once cooled, lift them out using the parchment paper edges and cut into squares. These brownies are perfect served with a glass of cold milk or a scoop of vanilla ice cream.

Adaptations for Special Diets

• Gluten-Free: Substitute the all-purpose flour with a 1:1 gluten-free flour blend.
• Vegan: Replace eggs with flax eggs (2 tablespoons ground flaxseed + 6 tablespoons water, set for 5 minutes) and use dairy-free chocolate chips.
• Lower Sugar: Reduce granulated sugar to 1/3 cup and brown sugar to 1/4 cup, or swap with coconut sugar.
• Nut-Free: This recipe is naturally nut-free, but always double-check chocolate chips for cross-contamination.

Steer Clear of These

• Using watery zucchini without draining – it can make the batter too runny and affect texture.
• Overmixing the batter – it leads to tougher brownies instead of soft, fudgy ones.
• Substituting cocoa powder with hot chocolate mix – this adds extra sugar and changes flavor.
• Skipping the baking powder or soda – these leaveners contribute to the perfect crumb.

Keep-It-Fresh Plan

Store your Double Chocolate Zucchini Brownies in an airtight container at room temperature for up to 3 days. To keep them moist longer, place a slice of bread in the container with the brownies—this simple trick helps retain moisture.

If you want to keep them fresh for up to a week, refrigerate the brownies wrapped tightly in plastic wrap or in a sealed container. Before serving, bring them back to room temperature or warm briefly in the microwave for that fresh-baked feel.

For longer storage, these brownies freeze beautifully. Wrap individual squares in plastic wrap and place them in a freezer-safe bag. They’ll keep for up to 3 months. Thaw overnight in the fridge or warm gently before enjoying.

Questions People Ask

Can I use frozen zucchini instead of fresh?

Fresh zucchini is best because it contains less moisture than frozen. If you only have frozen zucchini, thaw it completely and squeeze out as much liquid as possible before using.

Will these brownies taste like vegetables?

Not at all! The zucchini adds moisture and a subtle earthiness but is masked by the rich chocolate flavors. Even picky eaters won’t notice the veggie sneak-in.

Can I make these brownies without chocolate chips?

Absolutely! The chocolate chips add melty pockets of chocolate, but you can omit them or swap with chopped nuts, white chocolate chips, or dried fruit for a different twist.

How do I store leftover brownies?

Store them in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. They also freeze well for longer storage.
