- If you prefer a less sweet frosting, reduce the powdered sugar slightly or add a pinch of salt to balance the flavors.
- Make sure to squeeze excess moisture from the grated zucchini to prevent the cake from becoming too wet.

Can I use a different type of oil instead of vegetable oil?
Yes, you can substitute vegetable oil with canola oil or melted coconut oil for a similar texture and moisture level.
Do I have to peel the zucchini before grating?
No, there’s no need to peel the zucchini. The skin adds nutrients and a bit of color to the cake. Just make sure to grate and squeeze out excess moisture well.

- 3 cups powdered sugar
