To make this recipe gluten free, replace the all-purpose flour with a high-quality 1:1 gluten-free baking flour blend that contains xanthan gum, or add xanthan gum if your chosen blend does not include it. Also confirm that the baking powder, vanilla extract, powdered sugar, and any packaged ingredients are certified gluten free or free from cross-contact concerns. Because gluten-free dough can be slightly more delicate, chill it thoroughly before shaping and handle it gently when rolling and cutting. If the dough feels too soft, dust the work surface lightly with additional gluten-free flour as needed.
