To make these Orange Gingerbread Cookies with Rum Glaze gluten free, replace the all-purpose flour with a reliable 1:1 gluten-free baking flour blend that includes xanthan gum or a similar binder. Also confirm that the molasses, confectioners’ sugar, baking soda, spices, rum, and any packaged ingredients are labeled gluten free, since brands may vary or be processed in shared facilities. Because gluten-free dough can be a little more delicate, chill it thoroughly before cutting to help the cookies hold their shape. If your gluten-free flour blend does not already contain a binder, you may need to add a small amount of xanthan gum to improve texture and structure. For anyone with celiac disease or severe gluten sensitivity, use clean food processor parts, bowls, parchment, baking sheets, and utensils to avoid cross-contact.
