⭐ Granulated Sugar and Cornstarch Blend (Best Dairy-Free Option)
1 cup granulated sugar + 1 tablespoon cornstarch, processed to a fine powder to replace 1 cup powdered sugarPowdered sugar is essentially granulated sugar ground very finely with a small amount of cornstarch to prevent clumping. By blending granulated sugar with cornstarch and processing it in a food processor or blender, you recreate the fine texture and anti-caking properties necessary for proper incorporation into cookie dough. This ensures even sweetness and helps maintain the cookie's tender crumb.
For best results, pulse the mixture until it is very fine and powdery. Be careful not to over-process to avoid melting the sugar. Use immediately or store in an airtight container to prevent moisture absorption.
Compared to using straight granulated sugar, this substitute preserves the delicate texture and slight melt-in-the-mouth quality that powdered sugar contributes to chocolate chip cookies, resulting in a more authentic final product.
