What is the primary leavening agent in muffins?

• A. Steam
• B. Yeast
• C. Chemical leavening that forms carbon dioxide
• D. Air

Answer: (C)

In muffins, the rise comes mainly from chemical leavening that forms carbon dioxide. Baking powder or baking soda reacts with moisture and heat to generate CO2 gas, creating bubbles that expand the batter and set as the muffin bakes, giving that light, tender crumb. Steam can contribute a bit of lift during the baking process, but it’s not the primary mechanism. Yeast isn’t used in muffins because it requires fermentation time and would develop a different texture and flavor, and air alone isn’t enough to provide a sustained rise. So the key factor is the chemical leavening that forms carbon dioxide.
