This 3-ingredient slow cooker sunshine dump cake is the kind of easy dessert that feels like it came straight from a small-town church potluck table. It starts with plain dry yellow cake mix powder poured right into the bottom of the slow cooker, then gets dressed up with canned crushed pineapple and a bit of butter. Around here in the rural Midwest, we’ve been turning boxed mixes into company-worthy desserts since they first hit the shelves, and this one fits right into that tradition. You just dump, spread, and walk away, and a few hours later you’ve got a warm, sunny, spoonable cake that will have your husband circling back to the crock for seconds.
Serve this sunshine dump cake warm, scooped straight from the slow cooker into bowls. A small scoop of vanilla ice cream or a dollop of whipped topping melts down into the buttery, pineappley crumbs and makes each bite extra comforting. It’s lovely with a cup of coffee after Sunday dinner or a glass of cold milk in the evening. If you’re serving company, you can spoon it into pretty dessert cups and garnish with a little extra pineapple or a cherry on top for that old-fashioned Midwestern potluck look.
3-Ingredient Slow Cooker Sunshine Dump CakeServings: 8
Ingredients
1 box (about 15.25 oz) dry yellow cake mix powder
2 cans (20 oz each) crushed pineapple in juice, undrained
1/2 cup (1 stick/8 tbsp) unsalted butter, melted
Directions
Lightly grease the bottom and sides of a 5- to 6-quart slow cooker with a little butter or nonstick spray so the dessert releases easily.
Open both cans of crushed pineapple and pour the fruit and all the juices into the slow cooker. Spread the pineapple out into an even layer with a spoon.
Sprinkle the dry yellow cake mix powder evenly over the pineapple. Make sure the cake mix covers the fruit from edge to edge, but do not stir. You want the dry mix to sit right on top of the pineapple and juices.
Slowly drizzle the melted butter evenly over the dry cake mix layer, trying to moisten as much of the surface as you can. It’s fine if a few dry spots remain; the steam and pineapple juice will help hydrate them as it cooks.
Cover the slow cooker with the lid. Cook on HIGH for 2 to 2 1/2 hours, or on LOW for 4 to 4 1/2 hours, until the top is mostly set, the edges are golden, and the pineapple is bubbling up around the sides.
Turn off the slow cooker and let the dessert sit, covered, for about 15 minutes to thicken slightly. This rest helps the syrupy pineapple settle into the crumbly cake topping.
Spoon the warm sunshine dump cake into bowls and serve as-is or topped with ice cream or whipped cream. Keep the slow cooker on the “warm” setting for up to an hour if folks will be coming back for more.
Variations & Tips
For a slightly tangier version, replace one can of crushed pineapple with a 20 oz can of pineapple tidbits or chunks, keeping the juice. If you like a bit of crunch, sprinkle 1/2 cup chopped pecans or walnuts over the dry cake mix before drizzling on the butter. You can also use a butter or golden cake mix instead of plain yellow for a richer flavor. If your slow cooker runs hot and the edges brown too quickly, fold a clean kitchen towel under the lid to catch excess moisture and check it a little earlier. To stretch it for a crowd, serve smaller scoops over scoops of vanilla ice cream; the warm-and-cold contrast feels special and makes the dessert go further. Leftovers can be cooled, covered, and refrigerated for up to 3 days; reheat gently in the slow cooker on warm or in the microwave until just heated through.
