Instructions
Preheat oven to 325°F with a rack in the center. Butter or spray a 9-inch round cake pan (I have one like this, or try one of these) with cooking spray. Line the bottom of the pan with a circle of parchment paper and butter or spray that too.
In a strainer, toss zucchini with 1 cup of the sugar and let sit for 10 minutes to drain. Use your hands to squeeze out all the liquid you can.
In a mixing bowl, beat eggs with a fork, then beat in zucchini and oil.
Sprinkle in the flour, remaining 1 ⅔ cups sugar, cocoa powder, baking soda, baking powder, cinnamon and salt. Use the fork to stir the dry ingredients together a bit and then incorporate into the wet ingredients, mixing gently until well combined.
Stir in chocolate chips.
Scrape batter into pan and spread evenly.
Bake for 50 to 60 minutes, until the center doesn't jiggle and a tester comes out clean unless you hit a chocolate chip.
Cool in pan on a rack for at least 40 minutes before removing from pan to cool completely.
Sprinkle with powdered sugar and serve at room temperature.
Some of the sugar from the cup that you mix with the zucchini will inevitably fall through the strainer. Don't worry about it.
Occasionally, when removed from the oven after 50 minutes, this cake falls a bit in the middle. It's meant to be rustic and still looks beautiful, so I don't mind it. You can bake it longer to ensure that won't happen.
Make this cake up to 24 hours in advance.
Keep any leftovers covered on the counter for several days.
