This dump cake recipe takes advantage of not one, but three store-bought items for an easy homemade dessert. Canned cinnamon rolls are topped with ready-made cream cheese frosting and a box of cinnamon swirl coffee cake mix tops it all off in one 9 by 13 inch pan. Make sure to cover every bit of the cake mix is covered with butter - this provides the moisture it needs to cook properly. Check out more how to videos like this at Allrecipes.com.
