This Lemon Blueberry Dump Cake is the definition of “low effort, high reward.” It requires no mixing bowls, no measuring cups (mostly), and no skill. You essentially dump ingredients into a pan and bake, resulting in a bubbling, cobbler-like dessert with a crunchy, buttery lemon crust.

Why it works

The “magic” of a dump cake happens when the melted butter interacts with the dry cake mix during baking. It creates a crisp, golden topping that sits perfectly on top of the hot fruit filling. The zest adds a punch of fresh citrus oil that cuts through the sweetness of the canned filling, making it taste homemade rather than boxed.

What you need

1 box (15.25 oz) Lemon Cake Mix: Do not follow the instructions on the box. You only need the dry powder.
2 cans (21 oz each) Blueberry Pie Filling: This provides the “sauce” base. Alternatively, you can use 4-5 cups of fresh or frozen blueberries, but you may need to add a little sugar if they are tart.
1/2 cup (1 stick) Unsalted Butter: Cold and thinly sliced OR melted. Both methods work, but sliced butter often ensures more even browning spots.
1 tbsp Fresh Lemon Zest: Essential for brightening the flavor.
Optional Crunch: 1/2 cup chopped walnuts or pecans sprinkled on top before baking.

How to make it

Prep: Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray.
Layer Fruit: Pour the blueberry pie filling into the bottom of the dish. Spread it out evenly. Sprinkle the fresh lemon zest directly over the berries.
Layer Cake: Sprinkle the dry lemon cake mix evenly over the fruit. Do not stir. Stirring will ruin the “crust” effect and make a gooey mess.
Add Butter: Place thin slices of cold butter all over the top of the dry cake mix (try to cover as much area as possible). Alternatively, drizzle melted butter evenly over the top.
Bake: Bake for 45–55 minutes, or until the topping is golden brown and the fruit filling is bubbling vigorously around the edges.
Cool: Let it sit for 15 minutes to allow the sauce to thicken slightly before serving.

Tasty twists

Cream cheese swirls: Cut 4 oz of cream cheese into small cubes and scatter them over the fruit layer before adding the cake mix for creamy pockets.
Extra lemon: Squeeze half a lemon over the fruit filling before adding the cake mix for extra tartness.
Crunchy top: Sprinkle 1/4 cup of sliced almonds or pecans on top of the butter before baking for texture.
