These fluffy buttermilk blueberry muffins feature a tender crumb and a crunchy cinnamon streusel topping, perfect for breakfast or brunch. The recipe is quick, easy, and uses simple pantry ingredients.
Toss blueberries with flour before folding to prevent sinking. Use cold butter for streusel to maintain crumbly texture. Avoid overmixing batter to keep muffins light and fluffy. Baking at 400°F helps muffins rise quickly and develop a golden crust. Streusel topping can be made a day ahead and refrigerated.
