My neighbor brought this to a spring potluck once and everyone asked for the recipe. I still can't believe it only takes 3 ingredients to taste this incredible!

This oven baked 3-ingredient pineapple dump cake is the kind of recipe that quietly steals the show at a potluck. My neighbor brought it to a spring gathering years ago, and the entire table went back for seconds before anyone believed her when she said it only had three ingredients. It’s a classic Midwestern-style dump cake: you literally “dump” everything into a glass baking dish, slide it into the oven, and out comes a dessert with bubbly pineapple edges and a golden, buttery cake top. No mixer, no special skills—just pantry staples and a reliable oven. It’s perfect for busy weeknights, last-minute guests, or any time you want something warm, nostalgic, and unfussy.

Serve this pineapple dump cake warm, scooped straight from the glass baking dish so you keep those bubbly fruit edges intact. A scoop of vanilla ice cream or a dollop of lightly sweetened whipped cream plays nicely against the tangy pineapple and buttery cake topping. For a spring potluck or casual dinner, pair it with simple grilled or roasted meats and a fresh green salad to keep the rest of the meal light. Coffee, black tea, or a not-too-sweet dessert wine (like a late harvest Riesling) all complement the bright fruit and caramelized edges beautifully.

Servings: 8-10

1 (20-ounce) can crushed pineapple in juice, undrained

Preheat your oven to 350°F (175°C). Lightly grease a 9x13-inch glass baking dish so the cake releases easily and the edges don’t stick as they bubble up.

Pour the entire can of crushed pineapple, including all the juice, into the prepared glass baking dish. Use a spatula or the back of a spoon to spread the pineapple into an even layer that covers the bottom of the dish completely.

Sprinkle the dry yellow cake mix evenly over the pineapple layer. Do not stir. Gently shake the dish or tap it on the counter so the cake mix settles into a relatively even layer, covering as much of the fruit as possible.

Slowly drizzle the melted butter evenly over the dry cake mix, aiming to moisten as much of the surface as you can. It’s fine if a few dry spots remain; the pineapple juice will help hydrate those areas as it bakes.

Place the baking dish on the middle rack of the preheated oven and bake for 35–45 minutes, or until the top is golden brown, the edges are bubbly with pineapple, and the center looks set rather than wet. The fruit should be vigorously bubbling around the edges of the glass dish.

Remove the dish from the oven and let the dump cake cool for at least 10–15 minutes. This rest time allows the juices to thicken slightly so you get soft, spoonable portions with distinct layers of fruit and cake rather than a loose mixture.

Serve warm, scooped directly from the glass baking dish into bowls. Store any leftovers covered in the refrigerator and rewarm individual portions in the microwave until just heated through.

For a slightly different flavor, you can use pineapple tidbits instead of crushed pineapple, but keep the juice and lightly mash the fruit with a fork in the baking dish so it still creates a mostly even layer. If you prefer a sweeter, more caramelized top, use a butter golden or French vanilla cake mix in place of plain yellow. To add a little texture while still keeping the spirit of the original recipe, you can lightly sprinkle a small handful of shredded coconut or chopped nuts (such as pecans or walnuts) over the cake mix before drizzling on the butter—just know this technically adds a fourth ingredient. For a tangier profile, serve with a spoonful of vanilla yogurt instead of ice cream. If your oven runs hot, check the cake at the 30-minute mark; the glass dish retains heat, so a short rest on the counter will continue to cook the center slightly even after you pull it from the oven. Finally, if you’re baking ahead for a potluck, underbake by 2–3 minutes, then rewarm gently at 300°F (150°C) for 10–15 minutes at the event to bring back those appealing bubbly edges.
