To make this White Chocolate Cranberry Pound Cake gluten free, replace the all-purpose flour with a certified gluten-free 1:1 baking flour blend, including the tablespoon used for coating the cranberries. Verify that the baking powder, white chocolate chips, powdered sugar, dried cranberries, cream cheese, heavy cream, vanilla extract, and all packaged ingredients are labeled gluten free or free from gluten-containing additives. Use clean mixing bowls, utensils, measuring tools, and a clean loaf pan to prevent cross-contact with gluten-containing ingredients.
