Preheat oven to 350°F and grease a 9x13-inch baking dish thoroughly.
Wrap shredded zucchini in a towel and gently squeeze to remove excess moisture. Set aside.
In a large bowl, mix together flour, sugar, cocoa powder, baking soda, baking powder, and salt.
Add eggs and oil to the dry ingredients. Mix until just combined—don't overmix.
Gently fold in the zucchini and chocolate chips.
Pour batter into the greased pan. Bake for 45–50 minutes, or until a toothpick inserted in the center comes out clean.
Cool the cake completely before slicing. Enjoy!
Notes
This cake is rich and moist—you won’t even taste the zucchini! For an extra indulgent touch, serve with a dusting of powdered sugar or a dollop of whipped cream.
