To make this Cream Cheese Snowball Cookies Recipe gluten-free, replace the all-purpose flour with a certified gluten-free 1:1 baking flour blend. Confirm that the cream cheese, butter, vegetable shortening, white sugar, vanilla extract, almond extract, powdered sugar, and walnuts are gluten-free and free from cross-contact. Some extracts, powdered sugars, and nuts may be processed in facilities that handle wheat, so check labels carefully. Use clean bowls, baking sheets, utensils, and cooling racks to prevent cross-contamination.
