This 3-ingredient slow cooker vintage blueberry dump cake is the kind of recipe our moms and grandmas leaned on when they needed a cozy dessert without fuss. Everything gets tossed right into the crock, and a few hours later it tastes like you’ve been baking all day. Using canned blueberry pie filling keeps it simple and dependable, and the slow cooker does the work while you handle homework, errands, or just put your feet up for a bit.
Serve this blueberry dump cake warm right out of the slow cooker, scooped into bowls. It’s wonderful with a scoop of vanilla ice cream, a dollop of whipped cream, or even a spoonful of vanilla yogurt if you want to lighten it up a bit. A cup of coffee or hot tea on the side makes it feel like a little café treat at home, and for family gatherings you can set the slow cooker to warm and let everyone scoop their own dessert as they’re ready.
Slow Cooker Blueberry Dump CakeServings: 8
Ingredients
2 cans (21 ounces each) blueberry pie filling
1 box (15.25 ounces) yellow cake mix (dry, unprepared)
1/2 cup (1 stick) unsalted butter, melted
Directions
Lightly grease the inside of a 4- to 6-quart slow cooker with cooking spray or a thin layer of butter to help prevent sticking and make cleanup easier.
Spread the blueberry pie filling evenly over the bottom of the slow cooker, making sure the entire surface is covered. This will be your fruity base.
Sprinkle the dry yellow cake mix evenly over the blueberry pie filling. Aim to cover all the fruit; it will look like a layer of pale, powdery crumbs scattered across the dark blueberry filling, and that’s exactly right.
Drizzle the melted butter slowly and evenly over the dry cake mix layer, trying to moisten as much of the surface as possible. It’s okay if a few dry spots remain; they will turn into little crunchy, buttery bits 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 hours, until the top is mostly set, the edges are golden, and the blueberry filling is bubbling up around the sides.
Once done, turn the slow cooker to WARM and let the cake rest, covered, for about 10 to 15 minutes. This helps it thicken slightly so it scoops more neatly.
Spoon the warm blueberry dump cake into bowls and serve as-is or topped with ice cream or whipped cream. Keep the lid on the slow cooker when not serving to hold in moisture and warmth.
Variations & Tips
For a fun twist, you can swap one can of blueberry pie filling for cherry or apple pie filling to make a mixed-fruit version that still keeps the same easy method. If your family loves extra texture, sprinkle 1/2 cup chopped pecans or walnuts over the dry cake mix before adding the melted butter. For picky eaters who don’t like strong fruit flavors, use a white or butter cake mix instead of yellow for a milder taste. If you prefer things a bit less sweet, choose a pie filling labeled “light” or “no sugar added,” or stir in a squeeze of lemon juice to brighten the blueberries before adding the cake mix. To make this dairy-free, you can use a plant-based butter substitute that is meant for baking; just be sure it’s not a low-fat spread, as those contain more water and may not brown as nicely. Food safety tips: Always cook this on HIGH or LOW as directed, not on the “warm” setting, which isn’t hot enough to safely cook the ingredients. Keep the lid on during cooking so the temperature stays consistent. Leftovers should be cooled to room temperature within 1 to 2 hours, then transferred to a covered container and refrigerated for up to 3 days. Reheat individual portions in the microwave until steaming hot before serving. Avoid leaving the dessert sitting in the turned-off slow cooker at room temperature for long periods; once everyone has had dessert, either switch to WARM for short-term serving or pack leftovers away in the fridge.
