• Step 1: Preheat your oven to 350°F. Grease a 9×13-inch baking dish with nonstick cooking spray or butter.
• Step 2: In the prepared baking dish, spread the cherry pie filling in an even layer. Then, top with the undrained crushed pineapple, spreading it out to create an even layer.
• Step 3: Sprinkle the dry yellow cake mix evenly over the fruit. Drizzle the melted butter over the top of the cake mix, ensuring even coverage.
• Step 4: Bake for 45-50 minutes, or until the top is golden brown and the fruit is bubbly around the edges.
• Step 5: Allow the dump cake to cool for 15-20 minutes before serving. Enjoy warm, with a scoop of vanilla ice cream or a dollop of whipped cream, if desired.
