Variation on carrot cake - zucchini cake with cream cheese frosting

My mom grows giant zucchinis. I'm not kidding when I tell you that one of them is about the size of one of my thighs. My sister came to visit, and dropped off a boatload of food, including two giant zucchinis. We grilled one up, but I've been pondering what to do with the other one. This zucchini cake looks perfect to me!
