⭐ Cornstarch (Best Gluten-Free Option)
Replace 1 tablespoon of all-purpose flour with 1 tablespoon of cornstarchCornstarch is a pure starch that gelatinizes when heated, providing structure and tenderness without gluten development. In cheesecakes, it helps create a smooth and creamy texture by preventing the batter from becoming too dense or rubbery. Because cornstarch lacks protein, it cannot replace all the structural properties of flour alone, so it’s often used in combination with other flours or in small amounts. When substituting, it’s critical to maintain the proper balance to avoid a runny batter or a cheesecake that cracks easily. Cornstarch also improves moisture retention, which is beneficial for the creamy consistency of cheesecake.
