These moist lemon blueberry zucchini muffins feature a bright lemon zing, juicy blueberries, and a tender zucchini base topped with a crunchy buttery streusel. Perfect for breakfast or a snack, they are quick to make and delightfully flavorful.
Do not overmix the batter to keep muffins tender. Keep butter cold for the streusel topping to maintain crumbly texture. Use fresh lemon zest for best flavor. Squeeze zucchini well to avoid soggy muffins. If streusel browns too fast, tent with foil and/or reduce oven temperature to 325°F and bake longer. Muffins freeze well; thaw at room temperature or warm briefly before serving.
