Ingredients

2 cans (15 oz each) blueberry pie filling (or 4 cups fresh blueberries mixed with 1 cup sugar and 1 tablespoon cornstarch)
1 box (15.25 oz) yellow cake mix (or white cake mix)
1/2 cup butter, melted
1/2 teaspoon cinnamon (optional)
1/4 cup chopped nuts (optional, such as pecans or walnuts)

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

Directions

Preheat the oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick cooking spray.
Prepare the filling: Pour the blueberry pie filling (or fresh blueberry mixture) into the bottom of the prepared baking dish, spreading it out evenly.
Add the cake mix: Evenly sprinkle the dry cake mix over the blueberries. No need to mix or stir; just scatter it on top.
Add the butter: Drizzle the melted butter evenly over the top of the cake mix. Try to cover as much of the dry cake mix as possible for an even, golden topping.
Optional topping: Sprinkle the cinnamon and chopped nuts over the top for an added flavor boost and a bit of crunch.
Bake the cake: Bake in the preheated oven for 45-50 minutes, or until the top is golden brown and the blueberry filling is bubbling around the edges.
Serve: Allow the dump cake to cool for 10-15 minutes before serving. Serve warm, topped with whipped cream or vanilla ice cream if desired.

Variations

Different fruit: You can easily swap the blueberry pie filling with other fruit fillings, like cherry, peach, apple, or mixed berries, to create different flavor profiles.
More texture: Add a sprinkle of oats on top of the cake mix before baking for a crunchy, oat-strewn topping.
Coconut twist: Add shredded coconut to the top of the cake mix for a tropical flair.
Lemon zest: For a citrusy touch, add 1-2 teaspoons of lemon zest to the blueberry filling for a bright and fresh flavor.
Crispier topping: If you prefer a crunchier topping, mix the cake mix with a bit of brown sugar or a handful of crushed graham crackers before sprinkling it over the blueberries.

Storage/Reheating

FAQs

Can I use fresh blueberries instead of pie filling?

Yes, you can make your own blueberry filling using fresh blueberries, sugar, and cornstarch. Simply mix 4 cups of fresh blueberries with 1 cup of sugar and 1 tablespoon of cornstarch, then use this mixture in place of canned pie filling.

Can I use a different flavor of cake mix?

Absolutely! You can use white cake mix, butter cake mix, or even spice cake mix for a different flavor. Each will add its own twist to the dessert.

Can I make this dump cake ahead of time?

Yes, you can prepare the dump cake the day before and store it covered in the fridge. Reheat it in the oven for about 10 minutes before serving to get the top crispy again.

Can I use a different pan size?

Yes, you can use a 9×9-inch square pan for a thicker cake or adjust the baking time accordingly. If you use a smaller pan, you may need to bake it a bit longer.

Can I use margarine instead of butter?
