These fluffy blueberry muffins with a cinnamon-spiced streusel crumble topping are quick and easy to make, perfect for breakfast, potlucks, or a sweet snack. They deliver a tender crumb with bursts of blueberry and a buttery, crunchy topping.
Do not overmix the batter to keep muffins tender. Keep butter cold when making streusel for best crumbly texture. If streusel browns too quickly, cover muffins loosely with foil halfway through baking. Use frozen blueberries straight from freezer, tossed in flour to prevent sinking.
