Ingredients

  • 2 cups all-purpose flour
  • 12 cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 12 teaspoon baking powder
  • 12 teaspoon salt
  • 1 cup light brown sugar, scant
  • 12 cup unsalted butter
  • 1 teaspoon vanilla extract
  • 2 tablespoons brewed coffee, strong and cooled
  • 3 large eggs
  • 2 cups zucchini, unpeeled and grated
  • 1 cup bittersweet chocolate chips (I use Ghirardelli brand)
  • 1 tablespoon powdered sugar (optional)

Method

  • Preheat oven to 350 degrees F. Grease a 10-inch round springform pan (or an 8-9" cake pan lined with parchment paper and greased).
  • In a medium mixing bowl, whisk together flour, cocoa powder, baking soda, baking powder, and salt.
  • Set aside.
  • In the bowl of a mixer, beat sugar and butter until fluffy.
  • Add the vanilla, coffee, and eggs, mixing well between each addition.
  • Set aside.
  • In a large mixing bowl, combine the zucchini, chocolate chips, and about one-third of the flour-cocoa mixture, making sure the zucchini strands are well coated and not too clumpy.
  • Set aside.
  • Add the remaining two-thirds of the flour-cocoa mixture into the egg batter.
  • Mix until just combined; a thick batter will result.
  • Fold the zucchini-chocolate chip-flour mixture into the egg batter mixture and blend with a spatula without over-mixing.
  • Pour into the prepared cake pan and level the surface.
  • Bake for 40 to 50 minutes, until a knife inserted in the center comes out clean.
  • Transfer onto a rack to cool for 10 minutes.
  • Run a knife around the pan to loosen, and unclasp the sides of the pan (or carefully pull the cake out of the parchment paper).
  • Serve slightly warm or at room temperature, dusted with powdered sugar, if desired.
