In a large bowl, whisk together the flours, salt, baking soda, cocoa powder, salt and sugar. Then add in the oil, vanilla and coffee. Add in the zucchini. Mix until incorporated.
Oil a 9 inch cake pan and pour in the batter. If you want, use zucchini skin to make a pretty design on top (completely optional), and place into preheated oven.
Bake for about 35-45 minuted, or until a tester stabbed in the middle comes out clean.
Remove from oven and let cool in pan for at least 5 minutes the gently invert pan to remove cake and place on a rack to cool.
Serve as soon as you want..
