Zucchini is 95% water so we need to release some of that prior to baking! The accumulated water will make a big difference in these muffins. - I know it’s not a common kitchen tool, but using a potato ricer is one way to do it! - I use this method: Use a nut milk bag and squeeze out the moisture. - Use a thin dish towel, place zucchini in the middle and wring out the water!
