Why You’ll Love Chocolate Zucchini Cake
- Loaded with fresh zucchini. The not-so-secret ingredient — zucchini — adds texture, moisture, and little to no flavor. As far as vegetables go, zucchini is pretty flavorless. Which makes this summer squash a great addition when baking (and a great way to use up that abundant veggie from your garden). You basically get all the pros and none of the cons!
- It’s a healthier alternative to regular cake! Sure, you’re not avoiding the calories or the sugar, but you are adding some veggies and essential nutrients to your diet. This chocolate zucchini cake is good for health-conscious friends and kids who don’t like to eat their veggies.
- You’ll love the sweet cream cheese icing. Once you top this chocolate zucchini cake with your homemade cream cheese icing, you’ll see that you’re capable of creating a culinary masterpiece. With a dash of honey or maple syrup (or both!), the sweet icing pairs perfectly with the chocolate zucchini cake.

How to Make Cream Cheese Icing
To make easy cream cheese glaze, combine the softened cream cheese, milk, honey and sugar in a small mixing bowl. Mix well using a whisk or a hand mixer until smooth.
Then, use an icing spatula to spread the cream cheese icing evenly over the chocolate cake. Slice and serve.
