Ingredients

Scale
  • 2 cups (240g) all-purpose flour
  • 1 cup (200g) granulated sugar
  • ½ cup (100g) packed light brown sugar
  • 1½ teaspoons baking soda
  • ½ teaspoon baking powder
  • 2 teaspoons ground cinnamon
  • ½ teaspoon salt
  • 2 large eggs, at room temperature
  • ½ cup (120ml) vegetable oil
  • 1 teaspoon vanilla extract
  • 2 cups (about 2 medium) zucchini, shredded
  • ½ cup (113g) unsalted butter
  • 2 cups (240g) powdered sugar, sifted
  • 1 teaspoon vanilla extract (for frosting)
  • ½ teaspoon ground cinnamon (for frosting)
  • 23 tablespoons milk or heavy cream (for frosting)
  • A pinch of salt (for frosting)

Instructions

  1. Preheat your oven to 350°F (175°C). Prepare a 9×13-inch baking pan by greasing and lining it with parchment paper.
  2. Rinse the zucchini under cool water, trim the ends, and shred it using a box grater.
  3. In a large mixing bowl, whisk together flour, granulated sugar, brown sugar, baking soda, baking powder, cinnamon, and salt until well combined.
  4. Create a well in the center of the dry mixture. Crack the eggs into the well, then add the vegetable oil and vanilla extract.
  5. Gently stir with a spatula until just combined; do not overmix.
  6. Fold in the shredded zucchini until evenly distributed throughout the batter.
  7. Transfer the batter to the prepared baking pan, spreading it into an even layer.
  8. Bake for 28-32 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
  9. Once baked, cool the cake in the pan on a wire rack for 10 minutes.
  10. For the frosting, melt the butter in a saucepan over medium heat until golden brown and nutty.
  11. Add sifted powdered sugar, vanilla, cinnamon, and salt to the brown butter, and beat with a hand mixer until light and fluffy.
  12. Spread the frosting evenly over the cooled cake.
