I have no idea, but I can tell you how many it takes to make a double batch of chocolate zucchini bread (A la Chocolate and Zucchini, still my favorite food blog). You need one big, fat one that is too large to eat but absolutely perfect to grate into a chocolate-enriched cake batter.
And just that one big, fat zucchini will yield enough loaves of the cake to share, if you are so inclined. At the moment, I’m feeling generous (let’s spread those calories around…).
