Granulated Sugar and Cornstarch Blend (Best Option)
1 cup granulated sugar + 1 tablespoon cornstarch to replace 1 cup powdered sugarPowdered sugar is essentially granulated sugar ground with a small amount of cornstarch to prevent caking and provide a smooth texture. By replicating this blend, you maintain the sweetness and smoothness critical for cheesecake batter, which relies on fine sugar for even distribution and texture.
To ensure success, pulse the granulated sugar and cornstarch thoroughly in a high-speed blender or food processor until it reaches a powdery consistency. Be cautious not to over-process to avoid heat buildup which can melt the sugar.
This substitute closely mimics the original powdered sugar, preserving the creamy texture and sweetness of the cheesecake without introducing moisture or graininess.
