Aunt Carrie brought this to every winter get-together because it travels well and always gets compliments. One pan, big payoff. This blueberry dump cake is the kind of dessert you can throw together in minutes, tuck into the backseat, and serve warm at a church potluck or family game night. It uses pantry-friendly shortcuts—blueberry pie filling, a box of yellow cake mix, and a stick (or two) of butter—but comes out looking like something you fussed over all afternoon. The edges bubble up deep purple, the top turns golden and crumbly, and there’s always someone asking for the recipe before the pan is scraped clean.
There is something magical about a dessert that requires almost no effort yet delivers such spectacular results. Dump cake earned its name honestly—you literally dump the ingredients into a pan, and the oven does the rest. The fruit filling bubbles up through the buttery cake mix topping, creating pockets of jammy sweetness throughout. It is the ultimate shortcut dessert, perfect for when you need to bring something impressive but have zero time or energy to spare.
The Beauty of the Dump Cake
This recipe succeeds because of its brilliant simplicity. The blueberry pie filling provides a thick, sweet, intensely fruity base that requires no preparation. The yellow cake mix sprinkled on top creates a crumbly, golden crust as it bakes, absorbing some of the fruit juices while staying crisp and buttery. The butter melted and drizzled over the top is the secret—it soaks into the cake mix, transforming it into a rich, golden topping as it bakes.
The result is a dessert with incredible texture contrast: jammy, bubbling fruit underneath a crunchy, buttery, crumbly topping. Served warm with a scoop of vanilla ice cream, it is absolutely irresistible.
The Complete Recipe: Blueberry Dump Cake
Prep Time: 5 minutes | Cook Time: 45-50 minutes | Total Time: 50-55 minutes | Servings: 10-12
Ingredients
-
2 cans (21 ounces each) blueberry pie filling
-
1 box (15.25 ounces) yellow cake mix
-
1 cup (2 sticks) unsalted butter, melted
-
Optional: 1 teaspoon cinnamon or lemon zest for extra flavor
For Serving:
-
Vanilla ice cream or whipped cream
Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
2. Dump the Blueberry Filling
Pour both cans of blueberry pie filling into the prepared baking dish and spread it into an even layer.
3. Dump the Cake Mix
Sprinkle the entire box of dry yellow cake mix evenly over the blueberry filling. Do not stir. Use your fingers or a fork to break up any large clumps of the cake mix.
4. Add the Butter
Drizzle the melted butter as evenly as possible over the top of the cake mix. Try to cover as much of the surface as you can—the butter is what turns the dry mix into a golden, crispy topping.
5. Optional Add-Ins
If desired, sprinkle cinnamon or lemon zest over the top for extra flavor dimension.
6. Bake
Bake for 45 to 50 minutes, until the top is golden brown and the fruit is bubbly around the edges. The center may still look slightly jiggly—that’s perfectly fine.
7. Cool Slightly
Let the dump cake cool for 10 to 15 minutes before serving. This allows it to set slightly, making it easier to scoop.
8. Serve
Serve this blueberry dump cake warm, scooped straight from the pan into bowls. A scoop of vanilla ice cream or a dollop of whipped cream melts into the hot berries and crunchy topping and makes it feel extra special.
