Remove about half of the liquid from your crushed pineapple then place in a baking dish, approximately 11″ by 7″ in size, and spread into an evenish layer 🙂 .
Top with big dollops of the cherry pie filling and gently layer and slightly swirl it in with the pineapple.
Top evenly with yellow cake mix.
Add butter to cover surface of cake mix.
Bake at 350 degrees Fahrenheit for 50 minutes to 1 hour, until golden brown.
Let cool for at least 30 minutes, if you have the patience, then serve with vanilla ice cream.
