These moist and tender muffins combine shredded zucchini and juicy blueberries with a bright lemon streusel topping, perfect for breakfast or snacks.
Squeeze zucchini well to avoid soggy muffins. Toss blueberries in flour before folding to prevent sinking. Use cold butter for streusel to keep crumbly texture. Check muffins at 22 minutes to avoid overbaking. For gluten-free, substitute flour with gluten-free blend. For vegan, use flax eggs, dairy-free yogurt, and vegan butter.
