This recipe came from my high school friend's mother. It is so moist and delicious! My husband didn't want to have at first because of the zucchini, but he couldn't even tell it was in there! For a more healthy route, my sister-in-law does this: omit the butter, ¼ cup vegetable oil, and 3-3½ cups zucchini. Lastly, instead of buttermilk, you may use ½ cup milk+ ½ Tbsp apple cider vinegar or lemon juice- let mixture stand at least 5 minutes.
