To make this Gingerbread Bundt Cake Recipe gluten-free, replace the all-purpose flour with a high-quality 1:1 gluten-free baking flour blend that contains xanthan gum. Confirm that the cornstarch, baking powder, baking soda, spices, molasses, powdered sugar, maple syrup, vanilla extract, and all garnishes are certified gluten-free or free from gluten-containing additives. Grease and flour the Bundt pan using gluten-free flour or gluten-free baking spray. Use clean bowls, utensils, measuring tools, and cooling racks to prevent cross-contamination.
