Crowd-Pleasing Double Chocolate Zucchini Sheet Cake
This double chocolate zucchini sheet cake is an effortless way to feed a crowd! No mixer required. Plus, your guests won’t even know there’s zucchini in the cake!
My goodness… It’s been delicious couple of weeks!
We’ve been feasting on this moist double chocolate zucchini cake non-stop for couple of weeks. If you follow me on snapchat (I’m shineshka over there, by the way), you know what I mean. Batch after batch, I tested multiple variations of this cake to land on the moistest, fluffiest and the most chocolate-y version.
Oh, the things I do under the name of recipe testing…
But not a single soul complained about it! In fact, my mother-in-law was happy that I was taking all of the zucchini off of her hand. (Ok, not all of them, because her garden did so well this year, as usual.) And cake kept disappearing in the matter of day or two. Actually Garrat and I would polish off half of the cake before taking it to the ranch.
That’s what happens when the cake is so fluffy and moist! Also, loaded with chocolate…
And guess what? It’s sooooo simple to make this cake. No mixer required, which means I can make it while my little munchkin naps. He hates when I make noise when he’s resting. 🙂
Anyway, let’s talk cake…
What makes this cake the moistest and fluffiest of all?
Short answer: brown sugar and lots of grated zucchini.
We’re adding tiny bit of brown sugar, but it sure does make a huge difference. And as for zucchini, you don’t need to squeeze excess moisture out, as some of the recipes I’ve seen. You want all the moisture in there, and I promise it won’t make the cake soggy.
To seal the deal, we’re going to frost the cake with light and tangy sour cream frosting.
Sure, we could have used cream cheese frosting, but that would have made the cake a bit too heavy. With soft and fluffy sour cream frosting, this cake is simply to die for!
Now run to your nearest farmer’s market for fresh zucchini and make this cake asap. You’re gonna love it! And if you try this recipe, please report back. 😉
