Will no-bake fruit cake last at room temperature?

No, no-bake fruit cake should not be left at room temperature. Because it does not contain eggs or flour which would give structure due to baking, leaving a no-bake fruit cake unrefrigerated could pose a food safety risk as bacteria can grow in that environment. To maintain its quality and safety for consumption, a no-bake fruit cake should be kept refrigerated and only be taken out when needed. Additionally, the frosting used in a no-bake fruit cake may contain dairy products such as cream cheese or whipped cream, so refrigeration is needed to prevent spoilage.
