To make this Candy Cane Fudge gluten-free it's important to pay attention to details. The candy canes are the ingredient that needs consideration. Although candy canes are generally free of gluten it's crucial to read the labels for any hidden gluten or cross contamination risks especially if they are produced in facilities where gluten-containing products are also handled. It's recommended to choose brands that explicitly state their gluten-free status, for added safety. As, for the chocolate chips and sweetened condensed milk they usually don't contain gluten. It's still a good idea to quickly check their labels just to be sure.
