Description

This rich, fudgy chocolate zucchini cake is the perfect summer dessert—moist, decadent, and secretly packed with vegetables no one can taste!


Ingredients

Scale
  • 2 ½ cups all-purpose flour
  • ¾ cup unsweetened cocoa powder
  • 1 tsp baking powder
  • 1 ½ tsp baking soda
  • ½ tsp salt
  • 1 tsp espresso powder (optional)
  • ¾ cup vegetable oil
  • ¾ cup brown sugar
  • ¾ cup granulated sugar
  • 4 large eggs
  • ½ cup sour cream or Greek yogurt
  • 2 tsp vanilla extract
  • 3 cups shredded zucchini (lightly blotted)
  • 1 cup mini or semi-sweet chocolate chips


Instructions

  1. Preheat oven to 350°F (177°C). Grease and line two 9-inch round cake pans or a 9×13-inch sheet pan with parchment.
  2. In a large bowl, whisk together flour, cocoa powder, baking powder, baking soda, salt, and espresso powder.
  3. In another bowl, mix oil, brown sugar, granulated sugar, eggs, sour cream or yogurt, and vanilla extract until well combined.
  4. Gradually add dry mix to the wet ingredients. Fold in shredded zucchini and chocolate chips.
  5. Pour batter into prepared pans. Bake for 28–32 minutes (round cakes) or 35–38 minutes (sheet cake), or until a toothpick comes out with moist crumbs.
  6. Cool in pans for 10 minutes, then transfer to wire racks. Frost once completely cooled.

Notes

For variations, try cupcakes (bake 18–22 mins), loaf pans (check at 45 mins), or a triple chocolate version with ganache and chocolate chunks.
