To make Cherry Garcia Fudge gluten-free, ensure the white chocolate chips and mini chocolate chips are certified gluten-free, as some brands may contain trace amounts of gluten due to processing methods. Maraschino cherries are typically gluten-free, but always verify the label for additives. The remaining ingredients—sweetened condensed milk, butter, and salt—are naturally gluten-free. With these adjustments, the recipe remains identical in preparation and flavor.
