Ingredients
  

  • 1 Box yellow cake mix
  • 1 Can crushed pineapple (with juice)
  • 1 Can lemon pie filling
  • ½ cup unsalted butter, melted
  • ½ cup shredded coconut (optional)

Instructions
 

  • Preheat oven to 350°F (175°C).
  • Grease a 9x13-inch pan with butter or baking spray.
  • Dump the pineapple (with juice) into the pan and spread evenly.
  • Spoon lemon pie filling on top. Don’t mix just layer.
  • Sprinkle dry cake mix evenly over the top
  • Drizzle melted butter across the cake mix. It’s okay if some dry spots remain—they’ll crisp up
  • Bake for 35–40 minutes until golden brown and bubbling at the edges.
  • Let it rest for 5–10 minutes, then serve warm with vanilla ice cream.

Pro Tips

  • Don’t mix the layers. Let them bake into magic naturally.
    Metal pan = crispier edges, glass pan = more even bake.
    For richer flavor, try slicing cold butter and layering it instead of melting.
    Add-ins: Coconut flakes, lemon zest, or even a handful of chopped nuts.

Storage

  • Store leftovers covered at room temperature for up to 2 days.To reheat, microwave a single portion for about 15 seconds.

Feel free to customize it with shredded coconut, lemon zest, or even a handful of chopped nuts. And don’t forget that scoop of vanilla ice cream — it takes every bite to the next level!
