  • 2 medium zucchinis
  • 7 tbsp unsweetened cocoa powder
  • 2 tbsp butter softened
  • 3 eggs
  • 2 cups sugar
  • 1 1/2 cups applesauce
  • 1 tbsp vanilla extract
  • 1 1/2 all purpose flour
  • 1/2 cup wheat flour
  • 1 tsp baking soda
  • 1 tsp salt
  • 1 tsp ground cinnamon
  • 1 cup semi-sweet mini chocolate chips

Chocolate Glaze

  • 3/4 cup semisweet chocolate chips
  • 3 tbsp butter
  • 1 tbsp light corn syrup
  • 1/4 teaspoon vanilla extract


  • Preheat the oven to 350 degrees.
  • Grate the zucchinis and set on paper towels to absorb excess moisture. I ended up with a couple of cups of grated zucchini but it honestly doesn't affect the recipe if you have more or less. I would say between 2-3 cups is perfect.
  • Combine sugar, eggs, applesauce, zucchini, butter, and vanilla in a large bowl.
  • Combine the chocolate chips with a couple tablespoons of the flour to keep them from sinking to the bottom while the cake is baking.
  • Stir in the flour, baking soda, salt, cinnamon, cocoa powder, and chocolate chips.
  • Stir until all ingredients are thoroughly combined.
  • Pour the batter into a well-greased bundt pan. Bake the cake for 60-70 minutes or until an inserted toothpick comes out clean. Let the cake cool for ten minutes before inverting onto a plate.

Chocolate Glaze

  • Combine butter, chocolate chips, and corn syrup in a microwaveable dish. I use my Pyrex glass measuring cup because it makes it easy to drizzle the glaze over the cake.
  • Heat in the microwave in 30 seconds intervals at 50% power, stirring in between, until nicely melted.
  • Stir in vanilla extract. Drizzle over the top of the cooled cake. Enjoy!
