Ingredients

1/2 cup vegetable oil

1 1/2 cups sugar

1 teaspoon vanilla

1 2/3 cups flour

1/2 cup cocoa powder

1 teaspoon baking soda

1 teaspoon salt

2 cups shredded zucchini (packed)

For the Frosting:

1/4 cup salted butter

3 tablespoons cocoa powder

3 tablespoons milk

2 cups powdered sugar

1 teaspoon vanilla

Instructions

  1. Preheat the oven to 350°F (175°C) and spray a 9×13″ pan with cooking spray.
  2. In a large bowl, whisk together the vegetable oil, sugar, and vanilla.
  3. Sift in the flour, cocoa powder, baking soda, and salt, and stir until combined. The batter will be very thick.
  4. Stir in the shredded zucchini until the batter becomes a bit softer and more manageable.
  5. Pour the batter into the prepared pan and bake for about 20 minutes, or until a toothpick inserted into the center of the cake comes out clean.
  6. For the Frosting: In a microwave-safe bowl, melt the salted butter.
  7. Sift in the cocoa powder and add the milk, whisking until smooth. Microwave until the mixture starts boiling.
  8. Whisk in the vanilla extract and powdered sugar, stirring until the frosting is completely smooth.
  9. Pour the frosting over the baked cake. You can add the frosting while the cake is still warm or once it has cooled, depending on your preference.

Notes

You can substitute vegetable oil with any neutral oil, such as canola or sunflower oil.

Finely grated carrots or sweet potato can be used instead of zucchini, though the flavor will differ.

The zucchini skin can stay on for added fiber and texture.

This cake can be frozen for up to 3 months. Wrap it tightly and freeze the frosting separately.

If you prefer a lighter dessert, skip the frosting and dust the cake with powdered sugar or enjoy it plain.

For a spicier flavor, add a pinch of cinnamon, nutmeg, or cayenne pepper to the batter.
