These easy fluffy blueberry muffins with a crunchy streusel topping are perfect for a quick breakfast or snack, delivering a tender crumb and a satisfying crunch.
Do not overmix the batter to keep muffins fluffy. Fold in blueberries gently to avoid breaking them. Use cold butter for streusel topping to achieve crumbly texture. Tent muffins with foil if browning too fast. Avoid opening oven door early.
