Ingredients You’ll Need
- 1 box lemon cake mix
- 2 cans blueberry pie filling or about 4 to 5 cups blueberry filling
- 1/2 cup butter, melted or sliced thin
- Optional: 1 tablespoon lemon zest
- Optional: 1 to 2 tablespoons lemon juice
Optional for Serving
- Vanilla ice cream
- Whipped cream
- Fresh blueberries
- Powdered sugar
Ingredient Notes
Lemon cake mix gives the dessert its soft citrus flavor and buttery topping. Blueberry pie filling works especially well because it already has sweetness and a syrupy texture that bakes beautifully underneath the cake layer. Lemon zest or lemon juice can be added if you want even more bright lemon flavor.
How to Make This Lemon Blueberry Dump Cake
Step 1: Preheat the Oven
Preheat your oven to 350°F and lightly grease a 9×13 baking dish.
This helps the dessert bake evenly and makes serving easier once it is done.
Step 2: Add the Blueberry Layer
Spread the blueberry pie filling evenly into the bottom of the baking dish. If you are using lemon zest or lemon juice, stir it into the blueberry filling first or sprinkle it gently over the top.
This fruit layer becomes sweet, juicy, and bubbly as it bakes.
Step 3: Add the Cake Mix
Sprinkle the dry lemon cake mix evenly over the blueberry filling. Try to cover the fruit layer as evenly as possible without pressing it down.
This creates the soft cake topping as it bakes.
Step 4: Add the Butter
Drizzle the melted butter evenly over the cake mix, or place thin slices of butter all over the top if you prefer.
Try to cover as much of the cake mix as possible so the topping bakes up golden and crisp instead of dry in spots.
Step 5: Bake
Bake for about 40 to 50 minutes, or until the top is golden and the blueberry filling is bubbling around the edges.
The surface should look lightly crisp and buttery, while the fruit underneath should be hot and thickened.
Step 6: Cool Slightly and Serve
Let the dump cake cool for about 10 to 15 minutes before serving. This helps the filling settle slightly and makes it easier to scoop.
Serve warm on its own or topped with vanilla ice cream or whipped cream.

Tips for the Best Lemon Blueberry Dump Cake
For the best Lemon Blueberry Dump Cake, try to spread the butter as evenly as possible across the top. Any dry spots in the cake mix may stay powdery, so even butter coverage helps the topping bake more beautifully.
If you want a stronger lemon flavor, add fresh lemon zest to the blueberry layer before baking. This gives the dessert an even brighter citrus note without making it too tart.
Do not stir the layers once they are in the baking dish. Dump cakes work best when the fruit stays on the bottom and the dry cake mix stays on top.
Let the dessert rest for a few minutes after baking. This helps the bubbling fruit settle slightly and gives a better serving texture.
Serve it warm for the best experience. The fruit filling is extra delicious when hot, and the cake topping tastes amazing with cold ice cream.
Variations & Substitutions
This Lemon Blueberry Dump Cake is easy to customize.
- Use yellow cake mix instead of lemon cake mix for a milder citrus flavor
- Add cream cheese cubes for a richer version
- Mix in fresh blueberries with the pie filling for extra fruit texture
- Use blackberry or mixed berry filling for a variation
- Add sliced almonds on top for crunch
- Use white cake mix plus lemon zest if lemon cake mix is unavailable
- Top with sweetened whipped cream instead of ice cream
These small changes make it easy to adapt the dessert to your taste or pantry.
What to Serve with Lemon Blueberry Dump Cake
This dessert pairs beautifully with simple toppings and drinks. Great serving ideas include:
- Vanilla ice cream
- Whipped cream
- Fresh berries
- Powdered sugar
- Hot coffee
- Iced tea
- Lemonade
- Sweet cream
It is especially good as a spring or summer dessert, but honestly works any time of year.
Common Mistakes to Avoid
One common mistake is not covering enough of the cake mix with butter. If too much dry mix is left uncovered, some areas may stay powdery after baking.
Another mistake is stirring the layers. This dessert works best when the fruit stays on the bottom and the cake mix forms its own topping as it bakes.
Using too much extra liquid can also affect the texture. If you add lemon juice, keep it modest so the filling stays thick and not overly loose.
Taking it out too early is another issue. The top should be golden and the filling should be bubbling before it is done.
Finally, avoid serving it immediately straight from the oven without a short rest, because the fruit filling will be extremely hot and looser.
Storing Tips for the Recipe
Store leftover Lemon Blueberry Dump Cake covered in the refrigerator.
- Refrigerator: Up to 4 days
- Best way to reheat: Microwave individual portions or warm in the oven
- Best texture: Serve warm, especially with ice cream or whipped cream
You can enjoy leftovers cold too, but warming them gives the best soft-and-buttery texture.
