FAQ:

How do you shred zucchini for cookies?

To shred zucchini for cookies, wash the zucchini and trim the ends, then use a box grater or a food processor with a shredding attachment to shred it. Measure out what you need for the recipe then squeeze out excess moisture using a clean thin kitchen towel or cheese cloth. This step is crucial to prevent the cookies from becoming too wet.

Do I need to peel zucchini for baking?

No, there is no need to peel zucchini. In fact, the skin is a big source of nutrition, so it’s best to leave the skin on.

Can I make these cookies without nuts or chocolate chips?

Absolutely! The nuts or chocolate chips are optional and can be omitted if you prefer a simpler cookie. The base recipe with zucchini and oats is still delicious on its own.

Do I need to chill the dough before baking?

Yes. Chilling the dough allows for the flour and oats to absorb some of the moisture from the zucchini and prevents the cookies from spreading out too much in the oven.
