Ingredients
Scale
- Salted butter — quantity not specified in the source
- 1 bag mini chocolate chips
- Pure vanilla extract — quantity not specified in the source
- Eggs, at room temperature — quantity not specified in the source
- Powdered sugar — quantity not specified in the source
- Fresh zucchini, grated — quantity not specified in the source
- All-purpose flour — quantity not specified in the source
- Cocoa powder — quantity not specified in the source
- Baking powder — quantity not specified in the source
- Sea salt — quantity not specified in the source
- Chocolate chips, preferably dark chocolate — quantity not specified in the source
- For the frosting: melted butter — quantity not specified in the source
- For the frosting: 2 cups powdered sugar, plus more if needed
- For the frosting: cocoa powder — quantity not specified in the source
- For the frosting: vanilla extract — quantity not specified in the source
- For the frosting: warm milk — add as needed for consistency
Instructions
- Preheat the oven to 350°F. Line a 9×9-inch square baking pan with parchment paper.
- Add the salted butter to a pot over medium heat. Cook for 2 to 3 minutes, until the butter is lightly browned and smells toasted.
- Remove the butter from the heat and stir in the mini chocolate chips until completely melted. Mix in the vanilla extract.
- In a mixing bowl, whisk the room-temperature eggs for about 1 minute, until bubbly on top.
- Add the melted chocolate mixture and powdered sugar to the eggs. Whisk for 1 to 2 minutes, until smooth.
- Mix in the grated zucchini.
- Add the all-purpose flour, cocoa powder, baking powder, and sea salt. Stir just until combined, taking care not to overmix.
- Fold in the additional chocolate chips.
- Spread the brownie batter evenly in the prepared pan.
- Bake for 30 to 35 minutes, or until the thick brownies are just set in the center. Avoid overbaking to preserve their fudgy texture.
- To make the frosting, whisk together the melted butter, 2 cups powdered sugar, cocoa powder, vanilla extract, and warm milk.
- Add additional warm milk a little at a time until the frosting is thick but slightly drizzly. Taste and add more powdered sugar if needed.
- Spread the fudge frosting evenly over the brownies.
- Allow the frosted brownies to set for about 1 hour before slicing, or serve sooner for a softer, gooier texture.
Notes
- Use room-temperature eggs so they blend smoothly with the warm chocolate mixture.
- Finely grate the zucchini so it distributes evenly throughout the brownie batter.
- Do not overmix after adding the flour, as excessive mixing can make the brownies less tender.
- Watch the butter carefully while browning because it can go from toasted to burned quickly.
- For the fudgiest brownies, remove them from the oven when the center is just set rather than completely dry.
- Dark chocolate chips provide a deeper chocolate flavor, but semi-sweet chocolate chips may also be used.
- The brownies can be served without frosting for a simpler chocolate zucchini brownie.
- Store cooled brownies in a well-sealed container to help preserve their moist texture.
