To make this Chocolate Chip Snowball Cookies Recipe gluten-free, replace the all-purpose flour with a certified gluten-free 1:1 baking flour blend. Confirm that the powdered sugar, vanilla extract, fine salt, and mini chocolate chips are gluten-free and free from cross-contact. Some chocolate chips and powdered sugars may be processed in facilities that handle wheat, so check labels carefully. Use clean mixing bowls, baking sheets, parchment paper, utensils, and cooling racks to prevent cross-contamination.
