Instructions:
Prepare the Zucchini
The first crucial step for these brownies is preparing your zucchini. You’ll need 1 cup of grated zucchini. The key here is to remove as much excess moisture as possible. After grating, place the shredded zucchini in a fine-mesh sieve or a clean kitchen towel. Gently press down or twist the towel to wring out the liquid. This step is vital because too much moisture can make your brownies gummy. We want that zucchini to contribute moisture and tenderness, not watery density!
Melt the Chocolate and Butter Mixture
In a medium, microwave-safe bowl, combine the 3 tablespoons of butter (cut into pieces for easier melting) and the 3 tablespoons of semi-sweet chocolate chips. Microwave in 30-second intervals, stirring well after each interval, until the butter is completely melted and the chocolate chips are smooth and glossy. Alternatively, you can melt these ingredients in a double boiler over simmering water. Once melted and smooth, set this mixture aside to cool slightly. This forms the rich chocolate base of our brownies.
Combine Wet Ingredients and Cocoa
In a separate large bowl, whisk together the 1/3 cup vegetable oil, the 1/2 cup semi-sweet or dark chocolate chips, and the 2 tablespoons of unsweetened cocoa powder. Stir these together until well combined. Then, add the 1 cup of granulated sugar and stir until it’s incorporated into the oil and cocoa mixture. Next, add the 1 egg, 1 egg yolk, and 1 teaspoon of vanilla extract. Whisk everything together vigorously until the mixture is smooth and well-emulsified. Don’t skip whisking thoroughly; this helps to aerate the batter slightly, contributing to the final texture.
Incorporate the Dry Ingredients and Zucchini
Now, it’s time to add the dry ingredients to our wet mixture. Gently fold in the 1 cup of all-purpose flour, 1/4 teaspoon of baking soda, and 1/2 teaspoon of salt. Be careful not to overmix at this stage. Just mix until the flour streaks have just disappeared. Overmixing can develop the gluten in the flour too much, leading to tougher brownies. After the dry ingredients are mostly incorporated, gently fold in the prepared, squeezed-out grated zucchini. The batter will be thick at this point.
Create the Chocolate Swirl Topping
For that extra layer of chocolatey goodness and a beautiful finish, we’re going to make a quick ganache-like topping. In a small bowl, combine the 1 1/2 tablespoons of unsweetened cocoa powder, 3 tablespoons of semi-sweet chocolate chips, and 1 1/2 tablespoons of milk. You can microwave this mixture in short bursts (about 15-20 seconds) or heat it gently on the stovetop, stirring until everything is melted and smooth and you have a glossy, pourable chocolate sauce. This topping will be drizzled over the brownie batter.
Assemble and Bake
Preheat your oven to 350°F (175°C). Grease and flour an 8×8 inch baking pan, or line it with parchment paper, leaving an overhang on the sides to easily lift the brownies out later. Pour the brownie batter into the prepared pan and spread it evenly. Dollop spoonfuls of the chocolate swirl topping over the batter. Then, using a knife or a toothpick, gently swirl the topping into the batter. Don’t over-swirl; you want distinct streaks of chocolate. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crum extractbs attached (not wet batter). Be careful not to overbake, as this is what can lead to dry brownies.
Cool and Enjoy
Once baked, let the brownies cool completely in the pan on a wire rack. This is perhaps the hardest part – waiting! Cooling allows them to set properly, and the flavors to meld. Once cooled, you can lift them out using the parchment paper overhang. Cut them into squares and prepare for brownie bliss. The texture will be fudgy and incredibly moist thanks to that hidden zucchini. These are best stored in an airtight container at room temperature for up to 3 days, though they rarely last that long! Enjoy every decadent bite of these amazing chocolate zucchini brownies!
