Dump Cake

Gather all ingredients. Preheat the oven to 350 degrees F (175 degrees C).

Stir cherry pie filling and crushed pineapple together in a 9x13-inch pan and spread in an even layer.

Sprinkle dry cake mix evenly over pineapple and cherry mixture.

Sprinkle walnuts over cake mix; drizzle butter on top, making sure minimal dry spots remain.

Bake in the preheated oven until golden brown on top, about 35 to 40 minutes.
