Chocolate Zucchini Cake

READY IN: 1hr 10mins
Recipe by gnet9820

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.

Absolutely delish! But could you take a look at your instructions? #4 and #7 both have us mixing in the dry ingredients. I followed my instincts and creamed the liquids with the sugar and then the dry ingredients and milk. I also used the whole 10 oz bag of chocolate chips. I was going to eat them either way, so...:)
