Grate and weigh your zucchini
Preheat oven to 350℉
In a mixing bowl combine the eggs, brown sugar, and sugar with a wire whisk until smooth
Add the vanilla extract, vegetable oil, and salt. Whip with the whisk to combine until smooth
Place the drum sieve over a separate mixing bowl, add the flour, cocoa powder, and baking soda to the sieve and sift it through into the bowl underneath
Add half of the dry mixture to the egg and sugar mixture and mix to combine, add about half of the water or coffee, mixing to create a smooth batter. Repeat with the remaining dry ingredients, followed by the remaining water or coffee creating a smooth batter
Add the grated zucchini, the chocolate chunks, and chopped pecans to the batter and fold them in using a rubber spatula
Pour the finished batter into the prepared baking pan, and bake in a preheated 350℉ oven on the center rack for 45 minutes
Remove from the oven and place on a cooling rack. Cut and enjoy when completely cooled!
