These are incredible! So moist and tasty! Great way to use up some of zucchinis from your garden. Recipe is from Jacqueline's Markeplace and Cafe in Scottsdale. I've found that they are better if the batter is allowed to sit for 15 to 20 minutes before baking. This allows the zucchini to release the water. I love cinnamon, however if preferred you can reduce the amount of cinnamon. Muffins freeze well.
