This easy 3-ingredient slow cooker blueberry dessert is the kind of simple August treat that feels extra special with almost no effort. Using frozen blueberries, dry cake mix, and butter, it turns into a warm, jammy cobbler-style dessert with a buttery topping that is perfect for busy days, potlucks, or a cozy family supper. It is a wonderful way to make something sweet without heating up the kitchen, and the slow cooker does all the work.
Serve this dessert warm with a scoop of vanilla ice cream, a spoonful of whipped cream, or a little pour of cold heavy cream over the top. If you are bringing it to a gathering, it also pairs nicely with grilled summer dinners, brunch spreads, or simple coffee and tea after a meal. For a brighter finish, a little lemon zest on top can be lovely with the blueberries.
3-Ingredient Slow Cooker Blueberry Dump Dessert
Servings: 8
Ingredients
1 bag (32 ounces) frozen blueberries
1 box (15.25 ounces) yellow cake mix
1/2 cup (1 stick) unsalted butter, melted
Directions
1. Lightly coat the inside of a 5- to 6-quart slow cooker with nonstick spray or a little butter.
2. Pour the frozen blueberries into the bottom of the slow cooker and spread them into an even layer.
3. Sprinkle the dry cake mix evenly over the blueberries, covering the fruit as completely as you can without stirring.
4. Drizzle the melted butter all over the top of the cake mix, trying to moisten as much of the surface as possible. A few dry spots are fine.
5. Cover and cook on high for 2 to 2 1/2 hours or on low for 4 hours, until the blueberries are bubbling and the topping is set around the edges.
6. Turn off the slow cooker and let the dessert rest uncovered for 15 to 20 minutes before serving so the filling can thicken slightly. Spoon into bowls and serve warm.
Variations & Tips
Lemon Blueberry Version: Add 1 teaspoon of finely grated lemon zest over the blueberries before the cake mix goes on top for a fresh, bright flavor that tastes especially nice in late summer.
For Picky Eaters: If your family likes a sweeter topping, use white cake mix instead of yellow cake mix for a softer vanilla flavor. A scoop of vanilla ice cream on top also makes this dessert extra kid-friendly.
Keep the Layers Simple: Do not stir the ingredients together. Leaving them layered is what gives you the best cobbler-style texture, with fruit on the bottom and buttery topping on top.
Watch for Hot Spots: Slow cookers can run differently from one kitchen to another, so start checking near the end of cooking time. If the edges are done but the center still looks pale, give it a little more time with the lid on.
Make It Feel Special: For serving guests, spoon the warm dessert into small bowls and top with whipped cream or ice cream just before bringing it to the table. It is one of those easy desserts that feels comforting and homemade every single time.
