To make this Glazed Apple Cinnamon Ring gluten free, use certified gluten-free refrigerated cinnamon rolls or homemade gluten-free cinnamon roll dough. Confirm that the icing, raisins, pecans, and ground cinnamon are certified gluten free and processed without cross-contamination. If preparing homemade dough, use a high-quality gluten-free flour blend suitable for yeast or sweet roll dough. Gluten-free cinnamon rolls may be more delicate, so handle and arrange them gently before baking.
