Ingredients:

This Now, Make It Later!
  • 1 can (20 oz) crushed pineapple (with juice)
  • 1 box yellow cake mix
  • ½ cup (1 stick) butter, melted or sliced

Tools you’ll need:

  • Baking dish (9×13 inch)
  • Spoon (optional… honestly you can eyeball it!)

How to Make Pineapple Dump Cake

Now this is where it gets fun—because it’s almost too simple.

Step 1: Preheat your oven

Set it to 350°F (175°C). Let’s get that cozy warmth going.

Step 2: Add the pineapple

Pour the entire can of crushed pineapple (juice included!) into your baking dish. Spread it evenly—it’s going to become that gooey, caramelized base.

Step 3: Dump the cake mix

Sprinkle the dry cake mix evenly over the pineapple. Don’t stir. I know it feels wrong… but trust the process.

Step 4: Add the butter

Drizzle melted butter evenly over the top—or place thin slices across the surface. This is what creates that golden, slightly crisp topping.

Step 5: Bake

Bake for 40–45 minutes until the top is golden and bubbling around the edges.

Step 6: The flip reveal (optional but ICONIC)

Let it cool slightly, then scoop or flip a portion—watch that caramelized pineapple reveal itself underneath

That first bite? Warm, gooey, buttery perfection.

What to Serve with Pineapple Dump Cake

This cake is already a star, but here’s how to make it unforgettable:

  • A scoop of vanilla ice cream (melts right into the cake )
  • Fresh whipped cream
  • Toasted coconut flakes
  • A drizzle of caramel sauce
  • Iced coffee or tropical juice

Tips for Making It Perfect

  • Don’t drain the pineapple—you need that juice!
  • Spread butter evenly to avoid dry patches
  • Bake until golden, not pale (that top should be slightly crisp)
  • Let it rest 10–15 minutes before serving
  • For extra richness, use real butter (always worth it)

Storage Instructions

  • Room temperature: up to 1 day (covered)
  • Refrigerator: 4–5 days
  • Freezer: up to 2 months

Reheat in the microwave for that fresh-from-the-oven feel.

General Information

Dump cakes became popular in American kitchens for one reason: simplicity. No fuss, no stress, just layering ingredients and letting the oven do the work.

This pineapple version is especially loved because it mimics a pineapple upside-down cake—but without all the effort.

Frequently Asked Questions

Can I use fresh pineapple?

Yes, but you’ll need to add some juice or syrup to mimic the canned version.

Why is my cake powdery?

Butter may not have been evenly distributed—make sure to cover most of the surface.

Can I make this dairy-free?

Yes! Use plant-based butter alternatives.

Can I add more fruit?

Absolutely—mango or peaches work beautifully.

Do I need to mix anything?

Nope! That’s the magic of a dump cake.
