These fudgy one-bowl double chocolate zucchini brownies are moist, rich, and topped with a silky ganache. The zucchini adds a sneaky veggie boost without compromising the indulgent chocolate flavor.

Ingredients

Scale
  • 1 cup (120g) all-purpose flour
  • ½ cup (45g) unsweetened cocoa powder
  • ½ teaspoon baking powder
  • ¼ teaspoon salt
  • ¾ cup (150g) granulated sugar
  • ⅓ cup (75ml) vegetable oil or melted coconut oil
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 cup (120g) grated zucchini, squeezed to remove excess moisture
  • ½ cup (90g) dark chocolate chunks or chips
  • ½ cup (120ml) heavy cream (or coconut cream for dairy-free)
  • 4 oz (115g) dark chocolate, chopped
  • 1 tablespoon unsalted butter (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease the pan.
  2. Grate the zucchini using a box grater or food processor. Place the shredded zucchini in a clean kitchen towel and squeeze out as much moisture as possible.
  3. In a large mixing bowl, sift together the all-purpose flour, cocoa powder, baking powder, and salt.
  4. Add the sugar to the dry ingredients and stir to combine.
  5. In a separate small bowl, whisk together the oil, eggs, and vanilla extract until smooth.
  6. Pour the wet ingredients into the dry ingredients bowl. Stir gently with a spatula or wooden spoon until just combined.
  7. Fold in the grated zucchini and dark chocolate chunks evenly throughout the batter.
  8. Transfer the batter to the prepared baking pan, smoothing the top with a spatula.
  9. Bake for 25-30 minutes, or until a toothpick inserted near the center comes out with moist crumbs.
  10. While the brownies bake, heat the heavy cream in a small saucepan over medium heat until it just begins to simmer. Remove from heat and pour over the chopped dark chocolate in a heatproof bowl. Let sit for 2 minutes, then whisk gently until smooth and glossy. Stir in butter if using.
  11. Let the brownies cool in the pan for about 10 minutes before pouring the ganache evenly over the top. Spread with a spatula or the back of a spoon.
  12. Refrigerate for at least 30 minutes to let the ganache set before slicing. Use the parchment paper overhang to lift brownies out of the pan easily.

Notes

Squeeze out excess moisture from zucchini to avoid soggy brownies. Do not overmix the batter to keep brownies fudgy. Use good quality cocoa powder and chocolate for best flavor. Start checking brownies at 25 minutes to avoid overbaking. Ganache can be made in a microwave-safe bowl if preferred. Refrigerate brownies to set ganache before slicing.
