here's what you need:
one can crushed pineapple
one can cherry pie filling. this is very important. you don't want a can of cherries, you want the pie filling.
one box of vanilla cake mix
1/2 stick of butter or margarine.
here's what you do:
open both cans of fruit. dump the cherries in the bottom of a ungreased glass pan, making sure you cover the bottom. dump the pineapple right on top of the cherries, covering the bottom layer.
remember...this isn't a pretty cake, so it doesn't have to look beautiful.
then sprinkle the vanilla cake mix on top of the pineapple. again, this can just be dumped on. don't worry about the lumps!
cut up the butter or margarine into small pieces. if you'd rather shred the butter using a cheese grater, go for it. this is what my mom used to do when i was a kid. i don't have a grater, so i had to cut the butter into little chunks.
spread the chunks over the top of the cake mix. remember, it doesn't have to look pretty!
put the cake in a preheated 350 degree oven. cook for about 20-25 minutes or untill the cake is brown and the cherries bubble at the side. the liquid in the pineapple and cherries makes the cake moist and the butter gives the cake a crumbly topping. you don't want to overcook it though. just enough to brown the cake mix on top.
this cake tastes delicious with a scoop of vanilla ice cream on top. or cool-whip, whatever you prefer!
