Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Blueberry pie filling (or fresh blueberries tossed with sugar and cornstarch)
Lemon pie filling (or lemon curd as a substitute)
Yellow or lemon cake mix
Unsalted butter, melted or sliced
Fresh lemon zest (optional, for added brightness)
Optional: chopped nuts or shredded coconut for topping

Directions

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
Add the fruit base: Spread the blueberry pie filling evenly in the bottom of the baking dish. Spoon the lemon pie filling over the top and gently swirl for a marbled effect.
Sprinkle the cake mix: Evenly sprinkle the dry cake mix over the fruit layer. Do not mix.
Add butter: Drizzle melted butter evenly over the top of the dry cake mix. Make sure most of the surface is covered to avoid dry patches. Optionally, sprinkle on lemon zest, nuts, or coconut.
Bake for 40–45 minutes, or until the top is golden brown and bubbly.
Cool slightly before serving: Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream, if desired.

Variations

Use different berries: Try raspberries, blackberries, or a mixed berry blend.
Add cream cheese: Drop spoonfuls of sweetened cream cheese between the fruit layers for added richness.
Gluten-free: Use a gluten-free cake mix.
Add texture: Top with chopped pecans, walnuts, or granola for a crunchy finish.
Make it citrusy: Use orange or lime zest in place of lemon for a different twist.

Storage/Reheating

Store leftovers in the refrigerator in an airtight container for up to 4 days. To reheat, scoop a portion into a microwave-safe bowl and warm for 30–45 seconds. You can also reheat larger portions in the oven at 325°F (160°C) for 10–15 minutes. This cake is best served warm, but it’s also delicious cold or at room temperature.

FAQs

Can I use fresh blueberries instead of pie filling?

Yes. Toss fresh blueberries with sugar and cornstarch to create a thickened base similar to pie filling.

What type of cake mix works best?

Yellow or lemon cake mix pairs best with the fruit flavors, but white cake mix also works well.

Can I use lemon curd instead of pie filling?

Absolutely. Lemon curd adds a richer, tangier flavor and works as a great substitute.

Do I need to stir the layers?

No. Simply layer and bake—stirring will change the texture and intended results of a dump cake.

How do I prevent dry spots on top?

Be sure to evenly distribute the melted butter, covering most of the dry cake mix.

Can I make this in advance?

Yes. Bake it ahead of time and reheat just before serving. It also tastes great at room temperature.

Is it freezer-friendly?

Yes. Once cooled, wrap the cake well and freeze for up to 2 months. Thaw and reheat before serving.

Can I make individual servings?

Yes, divide ingredients into ramekins and bake for about 25–30 minutes until golden and bubbly.

Does this need to be refrigerated?

Yes. Because of the fruit and butter, leftovers should be refrigerated after cooling.

Can I add a crumb topping?

You can sprinkle a mixture of oats, brown sugar, and butter on top for a crisp-style finish.
