This Southern 3-ingredient pineapple cake is the ultimate back-pocket dessert you pull out when Sunday dinner is almost on the table and you suddenly remember you promised something sweet. Variations of this brilliant “dump-and-bake” style cake have floated around Southern church cookbooks and potlucks for decades because they are inexpensive, incredibly forgiving, and dangerously easy to eat straight from the pan!
It bakes up perfectly in a foil-lined tray with deeply golden, caramelized edges and a moist, tender yellow crumb, all thanks to canned crushed pineapple and a humble box of yellow cake mix. It is exactly the kind of dessert that mysteriously disappears while you’re busy carving the roast!
Why You’ll Love This Recipe
- 🍍 Tropical & Moist: The juices from the canned pineapple completely replace the eggs and oil, creating an impossibly tender crumb.
- ⏱️ True “Dump & Bake”: Prep takes under 5 minutes. No standing mixers, multiple bowls, or complicated measuring required!
- ✨ Only 3 Ingredients: You literally just need a box of cake mix, canned pineapple, and butter.
- 🧈 Caramelized Edges: Drizzling melted butter over the top creates a rich, crispy, cobbler-like crust that is highly addictive.
- 🥣 Minimal Cleanup: Mixing everything in one bowl and baking in a foil-lined pan means washing up is an absolute breeze.
What You’ll Need
- 1 box (15.25 oz) Yellow cake mix: Standard size, with no pudding added in the mix. (You will only use the dry powder, do not follow the box instructions!).
- 2 cans (20 oz each) Crushed pineapple: Keep them completely undrained! The juice is essential for hydrating the cake batter.
- ½ cup Unsalted butter: (1 full stick). Melted.
How to Make It (Step-by-Step)
Prep time: 5 minutes | Bake time: 35–45 minutes | Total time: approx. 50 minutes | Yield: 12 Servings
Step 1: Prep and Preheat
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with aluminum foil, letting it overhang the sides for easy lifting later. Lightly grease the foil with a thin film of butter or nonstick cooking spray!
Step 2: Combine the Base
In a large mixing bowl, pour in the dry yellow cake mix. Add both cans of crushed pineapple with all of their juice directly into the bowl with the dry mix.
Step 3: Stir the Batter
Stir the cake mix and pineapple together with a spatula or wooden spoon until you have a thick, evenly moistened batter. (It will look slightly lumpy from the fruit, but you should see absolutely zero dry pockets of flour mix).
Step 4: The Pan Spread
💡 Crucial Step: Pour the thick pineapple batter directly into the prepared foil-lined pan and spread it out into a perfectly even layer, nudging it deep into the corners with your spatula.
Step 5: The Butter Drizzle
Drizzle the melted butter evenly over the top of the raw batter, letting it naturally pool and streak across the surface. This is the secret to creating those rich, caramelized golden edges!
Step 6: The Golden Bake
Place the pan on the center rack of the preheated oven and bake for 35 to 45 minutes, or until the top is a deep golden brown and the edges are beautifully caramelized. (A toothpick inserted in the center should come out with just a few moist crumbs, no wet batter).
Step 7: Cool and Serve
Remove the pan from the oven and set it on a wire rack to cool for at least 20 to 30 minutes so it can set up properly. Use the foil overhang to gently lift the cooled cake from the pan, cut into squares, and serve warm!
💡 Expert Tips for Success
- 🧈 The Cobbler Crust: For a more pronounced, buttery, almost cobbler-like top crust, you can increase the melted butter to ¾ cup! Just watch the oven closely so the sugary edges don’t over-brown.
- 🛑 Don’t Drain the Fruit: The most common mistake with dump cakes is draining the canned fruit. The dry cake mix desperately needs that pineapple juice to hydrate and bake properly!
- 🧊 Let it Set: It is incredibly tempting to slice into this right out of the oven, but letting it rest for 20 minutes ensures you get clean, beautiful squares instead of a crumbly mess.
Variations and Substitutions
- 🍍 The Texture Mix: For a slightly tangier flavor and more bite, replace one can of the crushed pineapple with a 20-ounce can of pineapple tidbits! Chop them lightly before adding to give a fantastic mix of texture to the crumb.
- 🌿 The Warm Spice Upgrade: Stirring a teaspoon of pure vanilla extract or a heavy pinch of ground cinnamon directly into the batter complements the bright pineapple beautifully. (This technically bumps it to 4 ingredients, but it is well worth it!).
- 🥥 The Piña Colada Twist: Scatter half a cup of shredded sweetened coconut over the top of the batter right before you drizzle the melted butter for an incredible tropical crunch.
- 🥛 The Lighter Option: If you prefer a less rich cake, you can reduce the melted butter to just ⅓ cup. The cake will still be wonderfully moist from the pineapple juice, though the edges will be slightly less caramelized.
❓ Frequently Asked Questions (FAQs)
What should I serve with Pineapple Cake?
Serve this cake warm or at room temperature, cut into thick squares. A heavy scoop of vanilla bean ice cream or a dollop of lightly sweetened whipped cream plays flawlessly with the tangy pineapple and soft crumb! For a simple Sunday spread, pair it with hot coffee or tea after a hearty, savory meal like roasted chicken, roast beef, or meatloaf.
Can I bake this in a different pan?
Yes! You can absolutely bake this in two 8-inch square pans if you are cooking for smaller gatherings or want to freeze one for later. Just start checking for doneness a bit earlier, around the 25 to 30-minute mark!
How do I store and reheat the leftovers?
Because of the high moisture content from the fruit, you must store any leftover cake tightly covered in the refrigerator once it has fully cooled. It will keep perfectly well for about 3 days! Reheat individual squares for 15-20 seconds in the microwave to instantly bring back that soft, just-baked texture.
