Southern 3-Ingredient Pineapple Cake (Easy Dump Cake Recipe)
This Southern 3-Ingredient Pineapple Cake is the ultimate no-fuss dessert—moist, buttery, and packed with bright pineapple flavor. It’s one of those classic “dump-and-bake” recipes passed around in Southern church cookbooks for decades because it’s cheap, quick, and nearly impossible to mess up.
With just a box of cake mix, canned pineapple, and butter, you get a soft, tender crumb with rich, caramelized edges that taste like you spent hours baking.

Ingredients (Serves 10–12)
- 1 (15.25-ounce) box yellow cake mix (dry, not prepared)
- 2 (20-ounce) cans crushed pineapple in juice (undrained)
- ½ cup unsalted butter, melted
Step-by-Step Instructions
1. Preheat & Prepare the Pan
Preheat your oven to 350°F (175°C).
Line a 9×13-inch baking pan with aluminum foil, leaving extra overhang on the sides for easy lifting later. Lightly grease the foil.
Foil makes cleanup easy and helps lift the cake out cleanly.
2. Add Dry Cake Mix
Pour the dry yellow cake mix into a large mixing bowl.
Do NOT prepare it according to the box—use it dry.
3. Add Pineapple (With Juice)
Add both cans of crushed pineapple with all the juice directly into the bowl.
The pineapple juice replaces eggs, oil, and water.
4. Mix the Batter
Stir everything together until:
- Fully combined
- No dry pockets remain
- Batter is thick and slightly lumpy
5. Transfer to Pan
Pour the batter into the prepared pan and spread it evenly, making sure it reaches all corners.
6. Add Melted Butter
Drizzle the melted butter evenly over the top.
This step creates rich, golden edges and adds moisture.
7. Bake the Cake
Bake on the center rack for 35–45 minutes, or until:
- Top is deep golden brown
- Edges are slightly caramelized
- Toothpick comes out with moist crumbs (not wet batter)
Start checking around 30 minutes.
8. Cool Before Serving
Let the cake cool in the pan for 20–30 minutes.
This helps it set and makes slicing easier.
9. Slice & Serve
- Use foil edges to lift the cake out (optional)
- Cut into squares
- Serve warm or at room temperature
Perfect for casual, straight-from-the-pan serving.
Serving Suggestions
This cake shines on its own but pairs beautifully with:
- Vanilla ice cream
- Whipped cream
- Coffee or hot tea
- Fresh berries
Serve it after meals like:
- Roasted chicken
- Pork chops
- Meatloaf
Variations & Customizations
Keep the 3-ingredient simplicity by swapping instead of adding:

Replace one can crushed pineapple with pineapple tidbits (chopped) - Less Rich Version:
Reduce butter to ⅓ cup - Extra Buttery & Crisp Edges:
Increase butter to ¾ cup (watch closely while baking) - Optional Flavor Boost (breaks 3-ingredient rule):
Add vanilla extract or a pinch of cinnamon
Expert Tips for Best Results
- Always use undrained pineapple for moisture
- Don’t overmix—just combine until smooth
- Check early to avoid overbaking
- Let it rest before cutting for cleaner slices
- Expect a soft, slightly rustic texture (not a fluffy cake)
Storage & Food Safety
Refrigerator:
Store tightly covered for up to 3 days
Reheating:
Microwave individual slices for 15–20 seconds to restore softness
Important Tips:
- Let cake cool completely before storing
- Use fresh, undamaged canned pineapple
- Discard any bulging or rusted cans
