Forget the mixing bowls, the whisks, and the hours of kneading. Sometimes, the best dessert is the one that requires almost zero effort to create. Enter the Pineapple Dump Cake —a sunny, tropical treat that lives up to its name by having ingredients literally “dumped” into a baking pan.
This recipe is a masterclass in efficiency. With only four ingredients and a prep time of just 10 minutes, it delivers a high-reward, juicy cake that tastes like a homemade cobbler but assembles like a snack. Whether you are a beginner baker or last-minute host, this dish is your culinary safety net.
Why This Recipe Works
The appeal of a “dump cake” often gets lost in its unglamorous title, but the result is surprisingly sophisticated. The magic lies in the layering process, which creates distinct textures without any manual mixing.
- Textural Contrast: By using both sliced and crushed pineapple, you get a balanced mouthfeel. The slices provide structure, while the crushed fruit creates a saucy, jam-like base.
- Crispy-Topped Finish: The dry cake mix, when drizzled with butter and baked, transforms into a golden, crisp crust that resembles the topping of a classic fruit crumble.
- Minimal Cleanup: Since everything combines in the 9×13-inch baking dish, your kitchen stays clean, and your dishwasher stays happy.
“It’s basically like a pineapple cobbler, which I love having in my back pocket as we move into summer.”

The Four Essential Ingredients
The simplicity of this recipe relies on high-quality pantry staples. Here is why each component matters:
- Canned Pineapple (Sliced & Crushed): You need two 20-ounce cans. Using 100% juice packed pineapple ensures the right level of sweetness and acidity. The combination of forms provides the ideal balance of chunks and sauce.
- Light Brown Sugar: Half a cup of packed light brown sugar adds deep, caramelized notes that complement the tangy pineapple. Note: Dark brown sugar works as a direct swap if that is what you have on hand.
- White Cake Mix: A standard 15.25-ounce box of white cake mix provides a light, neutral flavor that caramelizes beautifully in the oven. Important: Ignore the instructions on the box; we are using this as a dry topping, not a batter.
- Unsalted Butter: Two sticks (8 ounces) of melted butter are drizzled over the top. Melting the butter ensures even distribution, allowing the dry cake mix to hydrate and crisp up perfectly. Tip: A few dry spots on top are okay; they will still bake into a crunchy texture.
Step-by-Step Instructions
Prep time: 10 minutes
Cook time: 45–50 minutes
Serves: 10
1. Prepare the Base
Preheat your oven to 350°F (175°C). Lightly coat a 9×13-inch baking dish with cooking spray.
2. Layer the Fruit
Pour one can of pineapple slices (including juices) into the dish. Arrange them into a single layer, tearing larger slices if necessary to fit. Add the second can of crushed pineapple (with juices) and use a flexible spatula to spread it evenly over the slices.
3. Add Sweetness and Structure
Sprinkle 1/2 cup of packed light brown sugar evenly over the pineapple layer. Next, pour the entire box of white cake mix over the fruit and sugar. Use an offset spatula to gently spread the mix into an even layer, covering all the fruit.
4. The Butter Drizzle
Drizzle the 2 sticks of melted unsalted butter evenly over the dry cake mix. Do not worry if a few patches of dry mix remain visible; the butter will spread during baking.
5. Bake and Cool
Place the dish in the oven and bake for 45 to 50 minutes. The cake is done when the top is a deep golden-brown and the fruit juices are bubbling vigorously around the edges.
Crucial Step: Let the cake cool for at least 1 hour before serving. This allows the sauce to thicken and the cake to set, making it easier to scoop.
Variations and Storage
Smart Swaps
- Buttery Flavor: Substitute the white cake mix with yellow cake mix for a richer, butterier taste.
- Softer Texture: Replace the sliced pineapple with a second can of crushed pineapple for a softer, more scoopable consistency.
Make-Ahead and Storage
- Make Ahead: You can assemble this cake up to 24 hours in advance. Keep it covered in the refrigerator until ready to bake.
- Storage: Store leftovers in the covered baking pan at room temperature for up to 3 days. Serve at room temperature for the best flavor and texture.
