Blueberry Dump Cake Ingredients

Blueberry Dump Cake raw ingredients that are labeled

You’ll need:

  • 2 (21-ounce) cans of blueberry pie filling
  • ¼ cup shredded coconut
  • 1 box of yellow cake mix
  • ¾ cup melted butter 

PRO TIP:

When buying the cake mix, it is best to pick one that doesn’t have pudding mix in it; check the label to make sure.

SUBSTITUTIONS AND ADDITIONS

FILLING: The blueberry pie filling can easily be substituted for any other type of pie filling as a way to change it up the next time you make this recipe.

COCONUT: Not a fan of coconut? Simply leave it out!

SPICES: You could also add a dash of brown sugar, cinnamon, or nutmeg as well to enhance the flavors. 

LEMON: Lemon is always a lovely complement to blueberry. Add a bit of lemon juice or lemon zest to your easy blueberry dump cake recipe. You could even substitute the yellow cake mix for lemon cake mix for an even more lemony flavor.

How To Make This Blueberry Dump Cake Recipe

OUR RECIPE DEVELOPER SAYS

You’ll want to use a 9×13-inch cake pan so that the texture and consistency are right. I’ve used an 11x 7-inch pan before, and it turned out a little too thick, which changed the delicious texture of the dump cake.

STEP ONE: Preheat your oven to 350°F. Spray a 9×13-inch baking dish with cooking spray. You don’t want anything to stick when it’s time to serve.

STEP TWO: Pour the blueberry filling directly into the prepared baking dish and spread it evenly.

STEP THREE: Sprinkle the shredded coconut on top of the pie filling.

STEP FOUR: Dump the dry cake mix evenly over the coconut.

STEP FIVE: Pour melted butter evenly over the top of the entire cake mix. Do not stir! 

STEP SIX: Bake for 50 minutes or until the top is golden brown. Serve warm. You can sprinkle more shredded coconut on top as well as a scoop of vanilla ice cream.

PRO TIP:

Because dump cakes are so gooey and moist, it can be hard to determine if they’re done. It’s normal to see some wet spots and some spots that are more crisp and done.

How To Serve

This perfect dessert is best served warm with a big scoop of vanilla ice cream and a spoonful of whipped cream or Cool Whip on top.

Storage

IN THE FRIDGE: I love this blueberry dump cake served hot, but it’s also yummy from the fridge. Cover this tasty dessert with plastic wrap and store it in the fridge for up to 4 days. Reheating can be done in the microwave if you would like.

IN THE FREEZER: If you have leftover dump cake, you can store it in the freezer in an airtight container for up to three months. I would suggest thawing in the refrigerator before serving.

FREQUENTLY ASKED QUESTIONS

Could you use fresh blueberries in this delicious cake recipe?

Yes, but it could change the consistency because the liquid would be different in fresh berries than in the canned filling. You might need to add a little water or extra butter to compensate.

What is a dump cake?

A dump cake is an easy and super moist cake in which the ingredients are simply dumped into the pan and baked. Usually, they use a box of cake mix and a handful of additional simple ingredients.

Can you make a dump cake ahead of time?

This is a great recipe to make ahead. You can make blueberry dump cake up to 2 days ahead of time. Just store it in the fridge until you are ready to serve.

Can I substitute a white cake mix for the yellow cake mix?

You can easily substitute white boxed cake mix for the yellow cake mix.

      You can, but you may need to add sugar or other sweetener and if you don’t think they will produce enough juice to moisten the cake mix you may need to add apple juice or blueberry juice. I think you may be able to get small containers in the baby food department.

    I have been making Dump Cakes for about 40 years. It is something I would use to teach Girl Scouts how to bake in a cardboard box oven. You Just about can’t mess it up. Since there is no dairy and no eggs even if it isn’t cooked as long as it could be; it is still good. I have a question though; I melt the butter, as you instructed, but several people have told me it is better with patties. My question is; do you think it makes any real difference?

    Thanks for keeping this old favorite going.

    • Layne Kangas says

      Hi, Mary – I’ve done it both ways and I don’t know if it’s that big of a difference that I’ve noticed! So glad you’ve enjoyed it for so many years!

    Hi! Would there be a difference if the cake mix was mixed with the butter first to make a crumble instead of pouring the butter on the cake mix? Thanks!
