Notes
The moisture from the zucchini is needed to prevent a dry cake so do not drain it after shredding. Processing the batter in a food processor will hide the grated zucchini. Peeling the zucchini is also an option to hide the green color.Using greased silicone cupcake liners is the best way to prevent the cupcakes from sticking to the mold.
