To make these Cinnamon Biscuits gluten free, replace the all-purpose flour with a certified gluten-free 1:1 baking flour blend. Also confirm that the baking powder, baking soda, confectioners’ sugar, vanilla extract, and cream cheese are certified gluten free or free from hidden gluten-containing additives if needed for strict dietary requirements. If your gluten-free flour blend does not already contain xanthan gum, add it according to the package directions for the best biscuit texture.
