What Is a Dump Cake?

A dump cake is exactly what it sounds like — a recipe where you dump the ingredients directly into the baking pan in layers, skip the mixing, and bake. There’s no creaming butter, no whisking eggs, no making batter. The dry cake mix on top absorbs moisture from the fruit below and the melted butter drizzled over everything, creating a crispy, crumbly, cobbler-like topping as it bakes.

It’s the ultimate no-fuss dessert and one of those recipes that genuinely seems too easy to be as delicious as it is.

• Incredibly forgiving. No technique required, no way to mess this up.
• Feeds a crowd. A 9×13 pan serves 12–15 people easily.
• Tastes like you tried hard. The bubbling pineapple filling and golden buttery crust are genuinely impressive.

The 3-Ingredient Pineapple Dump Cake

Ingredients

• 2 cans (20 oz each) crushed pineapple — do NOT drain
• 1 box (15.25 oz) yellow cake mix — any brand works
• 1 cup (2 sticks) unsalted butter, cold, sliced into thin pats

Optional add-ins that take it to the next level:

• ¾ cup sweetened shredded coconut (sprinkle over cake mix before butter)
• ¾ cup chopped pecans or macadamia nuts
• 1 can crushed pineapple + 1 can cherry pie filling (the classic combo!)
• Maraschino cherries scattered over the pineapple layer

Equipment

You need a 9×13-inch baking pan — that’s it. No mixer, no mixing bowls, no special tools. This truly is the easiest dessert you’ll ever make.

How to Make Pineapple Dump Cake

Step 1: Prep the Pan

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking pan with cooking spray or butter.

Step 2: Add the Pineapple Layer

Pour both cans of crushed pineapple — juice and all — into the prepared pan. Spread into an even layer. This is important: the juice is what gives the cake mix moisture to absorb and creates the saucy, bubbling filling as it bakes. Do not drain it.

Step 3: Add the Cake Mix

Open the box of dry cake mix and sprinkle it evenly over the pineapple layer. Do not stir. Do not mix. Just sprinkle the entire box in an even layer from edge to edge.

Step 4: Add the Butter

Slice 2 sticks of cold butter into thin pats and lay them across the top of the cake mix, covering as much surface area as possible. The more coverage you get, the crispier and more evenly golden your topping will be. Aim for pats every inch or so across the whole pan.

Step 5: Bake

Bake at 350°F for 45–50 minutes, until the top is golden brown and the pineapple filling is visibly bubbling around the edges. The center may look slightly underdone at 45 minutes but it will firm up as it cools. Don’t overbake — you want the topping golden, not dark brown.

Step 6: Cool Slightly and Serve

Let the cake cool for 10–15 minutes before serving. This allows the bubbling filling to settle slightly and makes it much easier to scoop. Serve warm with a generous scoop of vanilla ice cream or fresh whipped cream.

Tips for the Best Pineapple Dump Cake

• Don’t drain the pineapple. This is the #1 mistake. The juice is essential for a moist, bubbling filling.
• Cover every inch with butter. Any dry cake mix that doesn’t get covered by butter will stay powdery after baking. Thin pats, close together, edge to edge.
• Don’t stir anything. The layers need to stay separate to work their magic. Resist all urges to mix.
• Watch the edges. The edges bake faster than the center. If the edges are very dark but the center looks pale, loosely tent the pan with foil for the last 10 minutes.
• Let it rest. This cake is messy straight from the oven. Give it 15 minutes to settle before serving.

Delicious Variations

Pineapple Cherry Dump Cake

Replace one can of pineapple with a can of cherry pie filling. Layer pineapple first, then cherry pie filling on top, then cake mix, then butter. The combination is absolutely stunning and is probably the most popular dump cake variation there is.

Tropical Coconut Pineapple Dump Cake

Sprinkle ¾ cup of sweetened shredded coconut over the pineapple layer before adding the cake mix. The coconut toasts as it bakes and adds incredible tropical flavor and texture.

Pineapple Pecan Dump Cake

Add ½ cup of chopped pecans or macadamia nuts over the cake mix before the butter pats. They toast as it bakes and add a wonderful crunch to the golden topping.

Spiced Pineapple Dump Cake

Mix 1 teaspoon of cinnamon and ¼ teaspoon of ginger into the dry cake mix before sprinkling. It gives the cake a warm, spiced flavor that’s incredible in cooler months.

Make-Ahead and Storage

• Make-ahead: Assemble the layers in the pan (without baking), cover tightly, and refrigerate for up to 24 hours. Bake straight from the fridge, adding 5–10 extra minutes to the bake time.
• Leftovers: Store covered in the refrigerator for up to 4 days.
• Reheating: Reheat individual portions in the microwave for 45–60 seconds. Or reheat the whole pan uncovered at 325°F for 15–20 minutes to re-crisp the topping.
• Freezing: Not recommended — the topping loses its texture when frozen and thawed.

What to Serve with Pineapple Dump Cake

This cake is incredibly versatile and pairs well with almost everything:

• Vanilla ice cream — the classic choice. The cold, creamy ice cream melting into the warm cake is next-level good.
• Whipped cream — a lighter option that lets the pineapple flavor shine.
• Caramel drizzle — take it fully over the top for special occasions.
• A dusting of powdered sugar — simple and elegant for brunch or casual entertaining.

Frequently Asked Questions

Can I use a different flavor of cake mix?

Absolutely! White cake mix gives a lighter flavor that lets the pineapple shine. Butter pecan cake mix adds a rich, nutty depth. Lemon cake mix creates a bright, citrusy tang that pairs beautifully with pineapple. Spice cake mix is incredible with the pineapple cherry variation. Yellow cake mix is the classic choice because its buttery vanilla flavor is neutral enough to complement the fruit without overpowering it.

Why is my topping still powdery after baking?

This means some areas didn’t get enough butter. Make sure your butter pats are placed close together and cover the entire surface of the cake mix. You can also try melting the butter and drizzling it evenly over the top instead of using cold pats.

Can I use fresh pineapple?

Technically yes, but canned crushed pineapple is actually better here because the juice provides essential moisture for the cake mix to absorb. If using fresh, chop it very finely and add about ½ cup of pineapple juice to compensate for the missing liquid.

Can I make this gluten-free?

Yes! Simply substitute a gluten-free yellow cake mix. The recipe works exactly the same way and the result is just as delicious.

Can I double the recipe?

You can, but use two separate 9×13 pans rather than trying to fit it all in one pan. The layers need proper depth to work correctly, and overfilling the pan will result in an undercooked center and overflow in the oven.
