This easy 3-ingredient blueberry dump cake recipe combines two cans of blueberry pie filling, one box of yellow cake mix, and one cup of butter in a 9 x 13-inch baking dish. Bake it at 350°F (175°C) for 45–50 minutes, then let it rest for 10–15 minutes before serving.
The result is a warm, spoonable dessert with juicy blueberry filling underneath and a golden, buttery cake topping above. Serve it with vanilla ice cream or whipped cream for a simple after-dinner treat that tastes like a homemade fruit cobbler with almost no preparation.

Some desserts are worth making because they ask for special techniques, while others are favorites because they make busy days easier. This blueberry dump cake belongs firmly in the second group: open, layer, bake, and serve.
There is no bowl of batter to mix and no fruit to wash, trim, or sweeten. The canned pie filling already provides the saucy blueberry center, while the dry cake mix creates a tender, crumbly topping as it bakes with butter.
The contrast of textures makes every spoonful satisfying. You get soft berries and syrup at the bottom, a buttery golden surface at the top, and plenty of warm fruit flavor in between.

Ingredients You’ll Need
This recipe uses only three main ingredients, and each one has an important job in the finished dessert. Choose a standard yellow cake mix weighing approximately 15.25 ounces for the most familiar topping-to-filling balance.
- Blueberry pie filling: Use two 21-ounce cans, for 42 ounces total. The filling supplies the fruit, sweetness, color, and saucy texture.
- Yellow cake mix: Use one box and keep it dry. Do not add eggs, water, oil, or any other ingredients listed on the cake mix package.
- Butter: Use one cup of salted or unsalted butter. It may be melted and poured over the top, or sliced into very thin pats and distributed across the cake mix.
A 9 x 13-inch baking dish is the standard choice because it gives the layers enough room to spread. A lightly greased dish is optional, but it can make serving and cleanup a little easier.

How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C), giving it time to reach the correct temperature while you assemble the dessert. Lightly grease a 9 x 13-inch baking dish if desired, paying attention to the corners where the fruit filling may stick.
Step 2: Open both cans of blueberry pie filling and spoon them into the prepared dish. Use the back of a spoon or a spatula to spread the filling into one even layer, reaching close to each corner.
Step 3: Sprinkle the dry yellow cake mix over the blueberry layer. Shake it out gradually rather than dumping it all in one mound, then gently level the surface without pressing the mix down into the fruit.
Step 4: Add the butter over the entire cake mix surface. If using melted butter, pour it slowly in a zigzag pattern so it reaches as much of the dry mix as possible; if using solid butter, slice it very thinly and arrange the pieces edge to edge.
Step 5: Place the dish in the 350°F oven and bake for about 45–50 minutes. Watch for a golden-brown top and blueberry filling bubbling around the edges, which indicate that the dessert is ready to come out.
Step 6: Remove the dish from the oven and let it stand for 10–15 minutes. This short rest allows the bubbling filling to settle slightly and makes it easier to scoop without losing all of the warm fruit sauce.
Step 7: Serve the cake warm in bowls or shallow dessert plates. Add vanilla ice cream or whipped cream just before serving so the cool, creamy topping contrasts with the hot blueberries and buttery crust.
Pro Tips for the Best Texture
The most important rule is to leave the layers alone. Do not stir the blueberry filling, cake mix, and butter together, because the distinct layers are what create the signature dump-cake texture.
Butter coverage matters. Any cake mix left completely uncovered may remain powdery after baking, so spread melted butter patiently across the top or use thin butter slices for more dependable coverage.
When pouring melted butter, avoid pouring it into one spot and expecting it to spread on its own. A slow drizzle across several directions helps distribute the fat more evenly over the dry mix.
If you use salted butter, the dessert will have a subtle sweet-salty contrast. Unsalted butter also works well and gives you a slightly cleaner cake-and-blueberry flavor.
Keep an eye on the last few minutes of baking. Oven temperatures vary, so rely on the visual signs of a golden top and bubbling filling rather than treating the clock as the only test.

Serving Suggestions
Warm blueberry dump cake is excellent on its own, but a creamy topping makes it feel especially inviting. Vanilla ice cream is the classic choice because it melts into the berry sauce, creating a quick blueberry-and-cream combination.
Whipped cream offers a lighter finish and can be added in a generous spoonful just before serving. For a little extra color, scatter a few fresh blueberries over each portion if you have them available.
Serve the cake in individual bowls when it is very warm and soft. If you prefer neater portions, allow it to cool longer, though the topping and filling will naturally remain more spoonable than sliceable.
This dessert also fits comfortably on a casual brunch table or a family potluck. For a different party-friendly option, pair it with an easy cheeseburger dip at a relaxed gathering where guests can graze.
Storage and Reheating
Let leftover dump cake cool, then cover the baking dish or transfer portions to airtight containers. Refrigerate the leftovers so the fruit filling stays fresh, and enjoy them within a few days for the best texture.
Reheat individual portions gently until warm, then add ice cream or whipped cream after heating. The topping may soften somewhat in the refrigerator, but warming it brings back the buttery aroma and makes the berry filling pleasantly saucy.
You can also enjoy a chilled portion if you like a firmer, pudding-like texture. The dessert is forgiving, which is part of its appeal for make-ahead family meals and casual entertaining.
Common Questions
Can I use a different flavor of cake mix? This recipe is based on yellow cake mix, which provides a classic buttery flavor and golden color. Other mixes may change the sweetness, color, and texture, so use yellow cake mix when you want the expected result.
Should I prepare the cake mix first? No. Sprinkle the dry mix directly over the blueberry pie filling, then add the butter. Preparing it according to the box directions would change the proportions and prevent the dessert from forming its characteristic topping.
Why is part of my topping powdery? Powdery areas usually mean the dry cake mix did not receive enough butter. Next time, distribute the butter more evenly, especially around the edges and in any visibly dry patches.
Can I stir the dessert before baking? No. Keep the blueberry filling, dry cake mix, and butter in separate layers so they bake into a saucy fruit base and golden topping.
