Ridiculously easy to whip up, incredibly moist, and bursting with comforting cinnamon and allspice flavors, these muffins are a delicious way to use up sourdough discard and garden zucchini.
These muffins are adaptable! Consider adding chopped walnuts or pecans for crunch, mini chocolate chips for sweetness, or a pinch of nutmeg for extra spice. If you don't have Greek yogurt, sour cream or plain full-fat yogurt works. Any neutral oil can be substituted for coconut oil. For best texture, measure flour using the 'spoon and level' method. Shredded zucchini can be prepped the day before and stored in an airtight container.
