Ingredients

Scale

Cake Dry Ingredients:

  • 2 cups all-purpose flour
  • ½ cup natural cocoa powder
  • 1 cup granulated sugar
  • 1 cup light brown sugar
  • 1 ½ teaspoons baking soda
  • ½ teaspoon table salt

Cake Wet Ingredients:

  • 1 ½ cups shredded zucchini
  • 1 cup sour cream
  • 10 tablespoons melted butter
  • 2 large eggs
  • ½ cup steaming hot or boiling water
  • 2 teaspoons vanilla extract

Frosting Ingredients:

  • 2 ½ cups powdered sugar
  • 8 ounces cream cheese
  • ½ cup unsalted butter
  • ½ cup cocoa powder
  • ¾ teaspoon vanilla extract
  • ½ teaspoon table salt
  • 2 tablespoons mini chocolate chips

Instructions

  1. Warm your oven to precisely 350°F and thoroughly coat a 9×13 inch baking dish with butter, ensuring complete surface coverage.
  2. Combine 2 cups flour, 1 cup granulated sugar, 1 cup brown sugar, 1½ teaspoons baking soda, and ½ teaspoon salt in a large mixing bowl.
  3. Whisk ½ cup cocoa powder with ½ cup boiling water until the mixture transforms into a smooth, glossy liquid.
  4. Pour 10 tablespoons melted butter into the cocoa mixture, blending thoroughly with a whisk.
  5. Incorporate 1 cup sour cream, 2 lightly beaten eggs, and 2 teaspoons vanilla extract, mixing until the ingredients create a uniform consistency.
  6. Merge wet and dry ingredient mixtures, then gently fold in 1½ cups patted-dry zucchini until evenly distributed.
  7. Transfer batter to the prepared baking dish, spreading it uniformly across the surface.
  8. Bake for 33-35 minutes at 350°F, checking doneness by inserting a toothpick into the center – it should emerge completely clean.
  9. Allow cake to cool completely before frosting, giving it approximately 60-90 minutes at room temperature.
  10. Beat 8 ounces cream cheese and ½ cup butter until they reach a silky, integrated texture.
  11. Gradually add 2½ cups powdered sugar, stirring consistently to prevent lumps.
  12. Blend in ½ cup cocoa powder and mix until the frosting achieves a smooth consistency.
  13. Stir in ¾ teaspoon vanilla extract and ½ teaspoon salt, creating a rich, balanced flavor profile.
  14. Spread frosting evenly across the cooled cake’s surface using a spatula.
  15. Optionally garnish with 2 tablespoons mini chocolate chips for extra visual appeal and crunch.

Notes

  • Grate zucchini on the larger holes of a box grater to ensure moisture and texture throughout the cake.
  • Squeeze out excess liquid from zucchini using a clean kitchen towel to prevent a soggy cake bottom.
  • For a gluten-free version, swap regular flour with a 1:1 gluten-free baking blend that contains xanthan gum.
  • Store cake covered in the refrigerator for up to 5 days, letting it sit at room temperature for 15 minutes before serving to soften the frosting.
