To make these Cream Wafers gluten-free, replace the all-purpose flour with a certified gluten-free 1:1 baking flour blend suitable for cookies. Confirm that the powdered sugar, decorating sugar, vanilla extract, lemon extract, peppermint extract, food color, butter, and heavy whipping cream are labeled gluten-free. Some extracts, food colors, and decorative sugars may contain gluten-based additives or cross-contact warnings, so check labels carefully. Use clean mixing bowls, rolling pins, cookie cutters, parchment paper, baking sheets, decorating bags, and cooling racks to prevent gluten contamination.
