These fluffy mulberry muffins feature a soft crumb dotted with sweet-tart berries and a buttery, crisp streusel topping, perfect for a cozy breakfast or afternoon treat.
Use room temperature eggs and buttermilk for best results. Keep butter cold for streusel topping to ensure crumbly texture. Avoid overmixing batter to keep muffins tender and airy. If streusel browns too quickly, tent muffins with foil after 15 minutes. Cool muffins on rack to prevent soggy bottoms.
