Slow Cooker Apple Dump Cake

"This easy slow cooker dessert recipe has only 6 ingredients: apples, spice cake, ground cinnamon, melted butter, apple cider, and brown sugar! This rich cake is filled with sweet apple flavor, but takes only seconds to put together, and then the slow cooker does all of the work for you! It's sweet, easy, and the absolute perfect fall recipe! Plus, it feeds a crowd! We loved this recipe and I hope you will as well!"
