Dump cakes are usually a combination of canned fruit, pie filling or sometimes fresh fruit and cake mix. The fruit is usally drained, and then poured into a baking dish. Next, people usually "dump" a box of cake mix on top of the fruit. All recipes are different, but some call for butter on top of the cake mix as well. When the cake is baked, the cake mix bakes like a nice crusty crunchy topping for the fruit. (Kind of like a cobbler) You can do all different sorts of flavors. You can use a wide variety of fruits and flavors of cake mixes.
Dump cakes are pretty popular to make with children in the kitchen because they are incredibly easy to make and they require very little work! Plus, there is no measuring required!
One recipe I like to use for dump cakes is for black forest cake.
I use a can of cherry pie filling, 1 can of pitted cherries and a chocolate cake mix. (Sometimes I add chocolate chips as well)
Preheat the oven to 375. In a baking dish, pour the cherry pie filling and the pitted cherries in. Next add the chocolate chips if you would like. Finally, pour the chocolate cake mix on top. Bake for about 40 min or so.
Thats it! It is very simple, and incredibly delicious!
