There is something mighty fun about a dessert that looks like summer in a spoonful, and this slow cooker 3-ingredient ocean water dump cake does exactly that. It has that bright blue, beachy look folks love for cookouts, lake days, and Fourth of July tables, but it is about as easy as dessert gets. Dump cakes have long been a practical home-cook favorite across the Midwest because they stretch a few pantry items into something warm, sweet, and crowd-pleasing, and this playful version brings a little nostalgia and party charm right along with it.
Serve this cake warm straight from the slow cooker with a scoop of vanilla ice cream or a dollop of whipped topping to mellow the sweet citrus-coconut filling. For a summer spread, it fits right in beside grilled burgers, hot dogs, baked beans, and fruit salad, and if you are setting out a dessert table, a few maraschino cherries or a sprinkle of toasted coconut on top make it look extra festive.
Slow Cooker 3-Ingredient Ocean Water Dump Cake
Servings: 8
Ingredients
1 box white cake mix
1 can blue coconut-citrus pie filling or blue coconut-citrus dessert filling
1/2 cup (1 stick) unsalted butter, melted
Directions
1. Lightly grease the inside of a 4- to 6-quart slow cooker. Spoon the blue coconut-citrus filling into the bottom and spread it into an even layer.
2. Sprinkle the dry white cake mix evenly over the filling, covering the surface as completely as you can without stirring.
3. Drizzle the melted butter all over the top, trying to moisten as much of the cake mix as possible. Cover and cook on high for 2 to 2 1/2 hours, or on low for 4 hours, until the top is set and golden around the edges.
4. Turn off the slow cooker and let the dump cake rest, uncovered, for 10 to 15 minutes before serving. Spoon it out warm, making sure each serving gets some of the gooey blue filling and buttery crust.
Variations & Tips
Add a topping: A spoonful of whipped topping, a scoop of vanilla ice cream, or a sprinkle of toasted coconut can make this simple cake feel like a special-occasion dessert.
Watch the moisture: If you notice patches of dry cake mix before cooking, drizzle those spots with a little extra melted butter. Dump cakes do best when most of the top gets some butter coverage.
Try a citrus twist: A little fresh lime zest or lemon zest over the top just before serving gives the sweetness a brighter flavor and pairs nicely with the tropical color and coconut notes.
Keep the lid cracked at the end: If the top seems too soft during the last 20 to 30 minutes of cooking, set the lid slightly ajar with a wooden spoon handle to let some steam escape so the crust can firm up a bit more.
