โญ Unsalted Butter (Best Nut-Free Option)
1:1 (1 cup butter per 1 cup coconut oil)Butter works well because it has a similar fat content and solid state at room temperature, which helps maintain the muffin's structure and moisture balance. The milk solids in butter also contribute to browning and flavor complexity.
For best results, use unsalted butter softened to room temperature to ensure even mixing. Be mindful that butter melts faster than coconut oil, so avoid overmixing to prevent dense muffins.
Compared to coconut oil, butter provides a creamier mouthfeel and richer taste but lacks the subtle tropical notes of coconut, which may slightly change the flavor profile.
