Allow the cake to cool completely before storing it. This prevents condensation inside the storage container. Next, cover the container, either in an airtight container designed for a cake or by wrapping it tightly in plastic wrap. If the cake doesn’t have perishable fillings or toppings, then it can typically be stored at room temperature for 3-4 days. For longer storage or if the cake has perishable ingredients, store it in the refrigerator for 5-7 days. To freeze a Bundt cake, wrap it in plastic wrap and then foil. Freeze for up to 3 months. Thaw it in the refrigerator before serving.
