To make these Cinnamon Raisin Oatmeal Scones 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 make sure the oats are certified gluten free, since regular oats are often processed in shared facilities with wheat. Check that the baking powder, confectioners’ sugar, maple syrup, cinnamon, raisins, and any packaged ingredients are labeled gluten free, as brands may vary. Because gluten-free dough can be more delicate, chill the shaped scones for 10 to 15 minutes before baking if the dough feels too soft. For anyone with celiac disease or severe gluten sensitivity, use clean bowls, mixers, parchment, baking sheets, and utensils to avoid cross-contact.
