This 3-ingredient slow cooker Arbor Day dessert is the kind of easy, “dump and go” treat that makes busy family life feel a little more special. You simply pour canned whole mandarin oranges with all their juice into the slow cooker, sprinkle on a simple cake mix, dot with butter, and let the cooker do the work. It’s a cozy Midwestern-style dump cake that fills the house with a warm, citrusy smell and comes out tasting like a cross between a cobbler and a pudding cake—sweet, soft, and spoonable. It’s perfect for Arbor Day when you want something that quietly celebrates fruit and trees without needing to hover over the stove.
Serve this warm mandarin orange dessert straight from the slow cooker, scooped into bowls. It’s wonderful on its own, but a scoop of vanilla ice cream, a dollop of whipped cream, or a spoonful of vanilla yogurt makes it feel extra special. For a simple Arbor Day touch, sprinkle the top with a few fresh berries or a little shredded coconut to echo that “fruit from the trees” theme. A cup of hot tea or coffee for the adults and a glass of cold milk for the kids rounds everything out for a cozy family dessert night.
3-Ingredient Slow Cooker Mandarin Orange Arbor Day DessertServings: 6–8
Ingredients
2 cans (15 ounces each) whole mandarin oranges in their juice, undrained
1 box (about 15.25 ounces) yellow cake mix (dry, straight from the box)
1/2 cup (1 stick, 8 tablespoons) unsalted butter, cut into thin slices
Directions
Lightly coat the inside of your slow cooker with nonstick cooking spray or a very thin layer of butter to help with easy cleanup.
Dump the canned whole mandarin oranges and ALL of their juice into the bottom of the slow cooker. Spread them out so they cover the bottom in an even layer. The oranges and their juice should look like a bright, juicy bed at the bottom of the pot.
Sprinkle the dry yellow cake mix evenly over the top of the mandarin oranges. Do not stir. Try to cover the oranges and juice as evenly as possible so the cake mix can hydrate and cook consistently.
Lay the butter slices evenly over the surface of the dry cake mix, covering as much of the top as you can. This butter will melt down and help the cake mix turn into a tender, cobbler-like topping.
Cover the slow cooker with the lid. Cook on HIGH for 2 to 2 1/2 hours, or on LOW for 3 1/2 to 4 hours, until the top looks set and mostly dry in the center and the edges are bubbly. The texture will be soft and spoonable, like a pudding cake or cobbler, not a firm stand-alone cake.
Once done, turn off the slow cooker and let the dessert sit, covered, for about 10–15 minutes to thicken slightly and cool to a comfortable serving temperature.
Spoon the warm mandarin orange dessert into bowls, making sure to scoop down to get both the juicy oranges and the tender cake topping in each serving. Serve warm with your favorite toppings, if desired.
Variations & Tips
For picky eaters, you can mash the oranges slightly with a spoon before adding the cake mix so there are fewer big fruit pieces—they’ll still get the flavor without noticing the texture as much. If you’d like a little extra flavor, sprinkle 1/2 teaspoon of ground cinnamon or a teaspoon of vanilla extract over the oranges before adding the cake mix (this technically adds ingredients, but they’re optional flavor boosts). You can also swap the yellow cake mix for white cake mix or even a lemon cake mix for a brighter citrus punch. If your slow cooker tends to run hot, check the dessert about 30 minutes earlier than the time listed so the edges don’t overcook; every slow cooker is a bit different. For a slightly lighter version, you can use a reduced-sugar cake mix if available, and serve with plain Greek yogurt instead of ice cream. Food safety tips: Always make sure your canned mandarin oranges are not expired, the cans are not bulging or damaged, and the fruit smells fresh when opened. Keep the slow cooker covered while cooking so the temperature stays consistent. Once cooked, refrigerate leftovers within 2 hours in a shallow, covered container, and enjoy within 3–4 days. Reheat portions gently in the microwave until steaming hot before serving again.
