Baking Powder (Best Option)
1 teaspoon per 1 cup of flour or batterBaking powder is a chemical leavening agent that releases carbon dioxide gas when moistened and heated, causing the batter to expand and become lighter. In cheesecakes, which are typically dense and creamy, baking powder helps introduce a slight lift and airiness without fermentation. This is important because yeast is rarely used in cheesecakes, so baking powder is the closest functional substitute.
For best results, ensure the baking powder is fresh and evenly mixed into the batter. Avoid overmixing after adding to prevent deflation. Monitor baking time as the rise may be quicker than yeast-based doughs.
Compared to yeast, baking powder provides immediate leavening without flavor changes from fermentation, preserving the cheesecake’s classic creamy texture and tangy taste while improving lightness.
