Why This Recipe Works
No Fuss: This zucchini sheet cake is the definition of a no fuss dessert. It is probably the easiest cake you will ever make! Simply mix the dry ingredients with the wet ingredients, bake and voila! You’ll have an absolutely delicious zucchini cake that you can eat at any time of the day. Seriously, this cake would be just as good in the morning as it is for dessert after dinner!
Veggie Cake: I know that having veggies in a cake may sound odd, but stick with me here. The zucchini adds moisture and nutrients to this cake without making it taste like it is healthy. And if you want a sweet treat, you can top it off with the homemade creamy frosting that pairs perfectly here!
Ingredients
For the Cake
- Flour: All-purpose flour works great here. For a gluten-free zucchini sheet cake, use a gluten-free replacement flour!
- Baking Soda: Baking soda helps the cake to rise and get nice and fluffy!
- Cinnamon: Cinnamon is a warm spice that gives this cake a flavor similar to carrot cake!
- Salt: A little bit of salt is needed to balance all the flavors.
- Zucchini: Shredded zucchini adds moisture to this cake. Zucchini has such a mild flavor that you won’t feel like you are eating vegetables at all!
- Brown Sugar: Brown sugar gives this cake a deeper flavor!
- Sugar: To make sure things are nice and sweet.
- Eggs: For structure and rise!
- Vanilla: Vanilla extract will add extra flavor to your zucchini cake.
- Plain Yogurt: I used fat free greek yogurt, but you can use regular plain yogurt or even substitute this with sour cream!
For the Frosting:
- Butter: Melted butter is used to add lots of rich flavor to this zucchini sheet cake.
- Powdered Sugar: For a sweet cream cheese frosting!
- Cream Cheese: Cream cheese is great in frosting because it adds a slightly tangy flavor! Make sure it is room temperature!
- Vanilla Extract: For flavor!
- Milk: The milk will get the frosting to your desired consistency. Feel free to use more if you want it to be runnier!
