This slow cooker 3-ingredient Orange Crush dump cake is the kind of easy dessert that saves the day when you need something fun, sunny, and crowd-pleasing without heating up the kitchen. Dump cakes became popular for good reason: they turn a handful of pantry staples into a warm, spoonable treat with almost no fuss, and this citrusy version has a bright orange flavor that feels just right for potlucks, cookouts, and easy family desserts.
Serve this warm on its own or scoop it into bowls with vanilla ice cream or whipped topping for a creamy contrast to the sweet orange flavor. It also pairs nicely with fresh berries, a little orange zest on top, or even a simple glass of iced tea or coffee if you’re setting out a casual dessert table for guests.
Slow Cooker 3-Ingredient Orange Crush Dump Cake
Servings: 8
Ingredients
1 box yellow cake mix, about 15.25 ounces
1 can orange soda, 12 ounces, such as Orange Crush
1 can mandarin oranges in juice, 15 ounces, undrained
Directions
1. Lightly coat the inside of a 4- to 6-quart slow cooker with nonstick spray or a little butter to help prevent sticking.
2. Pour the undrained mandarin oranges into the slow cooker and spread them into an even layer across the bottom.
3. Sprinkle the dry yellow cake mix evenly over the oranges, covering the fruit as completely as you can.
4. Slowly pour the orange soda over the cake mix, aiming to moisten as much of the surface as possible. Do not stir.
5. Cover and cook on high for 2 to 2 1/2 hours or on low for 4 hours, until the top looks set and golden around the edges and the filling is bubbling.
6. Turn off the slow cooker and let the dump cake rest for 10 to 15 minutes before scooping and serving warm.
Variations & Tips
For a richer topping: If you want a more buttery, bakery-style finish, dot 4 tablespoons of thinly sliced butter over the top before cooking. It’s not necessary, but it gives the crust a deeper golden color and a softer crumb.
For picky eaters: If your family doesn’t love fruit pieces, gently break up the mandarin oranges with a spoon before adding the cake mix so the filling bakes up smoother while still keeping that bright orange flavor.
Make it a creamsicle dessert: Serve each portion with vanilla ice cream or whipped topping. That creamy addition really brings out the orange soda flavor and makes the whole dessert taste a bit like an old-fashioned creamsicle.
Slow cooker tip: Every slow cooker runs a little differently, so start checking near the early end of the cooking time. If the center still looks wet on top, give it a little more time with the lid on until the cake layer looks set and the edges are bubbling nicely.
