Instructions:
Let’s get started on making these amazing brownies! The process is straightforward, and the results are so worth it.
Step 1: Prepare Your Zucchini and Preheat the Oven
First things first, we need to get our zucchini ready. Grate about one medium zucchini. The key here is to squeeze out as much moisture as possible. You can do this by wrapping the grated zucchini in a clean kitchen towel or paper towels and squeezing firmly. Excess water can make your brownies soggy, and we want that perfect fudgy texture. Once you’ve prepped the zucchini, set it aside. Next, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Grease and flour an 8×8 inch baking pan, or line it with parchment paper for easy removal. I like to use parchment paper because it makes lifting the brownies out of the pan a breeze for slicing.
Step 2: Melt the Chocolate and Combine Wet Ingredients
In a medium heatproof bowl, combine the 1/3 cup vegetable oil and the 1/2 cup semi-sweet or dark chocolate chips. You can melt this in the microwave in 30-second intervals, stirring in between, until the chocolate is smooth and fully melted. Alternatively, you can use a double boiler. Once melted, stir in the 2 tablespoons of unsweetened cocoa powder until well combined and there are no streaks of dry cocoa remaining. This step helps to bloom the cocoa powder, intensifying its chocolate flavor. In a separate large bowl, whisk together the 1 cup granulated sugar, 1 egg, and 1 egg yolk. Add the 1 teaspoon of vanilla extract and whisk until the mixture is smooth and slightly lighter in color.
Step 3: Incorporate the Chocolate Mixture and Zucchini
Pour the melted chocolate and oil mixture into the sugar and egg mixture. Whisk everything together until it’s fully incorporated and you have a rich, chocolatey batter. Now, it’s time to add our secret ingredient! Gently fold in the 1 cup of grated, squeezed zucchini. Don’t overmix at this stage; we just want to distribute it evenly throughout the batter. The zucchini will seem like a lot, but trust me, it disappears into the brownie goodness, adding incredible moisture and tenderness.
Step 4: Combine Dry Ingredients and Mix into Batter
In a small bowl, whisk together the 1 cup all-purpose flour, 1/4 teaspoon baking soda, and 1/2 teaspoon salt. Now, gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix the batter at this stage, as overmixing can lead to tough brownies. A few streaks of flour are okay; they’ll disappear as you fold in the zucchini. Once the dry ingredients are mostly incorporated, fold in the grated zucchini gently.
Step 5: Bake the Brownies and Make the Chocolate Glaze
Pour the brownie batter into your prepared baking pan and spread it evenly. If you like, you can sprinkle a few extra chocolate chips on top for an extra chocolatey finish. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crum extractbs attached (not wet batter). While the brownies are baking, let’s make a quick and easy chocolate glaze. In a small saucepan over low heat, melt the 3 tablespoons of unsalted butter. Once melted, stir in the 1 1/2 tablespoons of unsweetened cocoa powder until smooth. Remove from heat and whisk in the 3 tablespoons of semi-sweet chocolate chips and the 1 1/2 tablespoons of milk until you have a smooth, glossy glaze.
Step 6: Cool, Glaze, and Enjoy!
Once the brownies are baked, let them cool completely in the pan on a wire rack. This is a crucial step for fudgy brownies – they continue to set up as they cool. Once cooled, gently drizzle the chocolate glaze over the top of the brownies. Let the glaze set for a few minutes before cutting into squares. The result? The best chocolate zucchini brownies you’ve ever had – incredibly moist, intensely chocolatey, and with a hidden healthy boost! These are truly a crowd-pleaser, and no one will ever guess the secret ingredient. Enjoy every delicious bite!
