Only 3 Ingredients!

If you’ve never made a dump cake before, they’re super easy. It’s called a dump cake because you simply “dump” everything into the same pan that you bake the cake in. They have a fruit filling layer on the bottom, and a buttery cake/crumble layer on top. They’re super similar to a fruit crisp or cobbler.

I’ve made several dump cakes in the past, but today’s is a blueberry version, which is a favorite for BBQs and potlucks because I don’t think anyone can say no to a delicious berry dessert! And definitely not when it’s topped with a cold scoop of vanilla ice cream. 😉

Its simple, quick and only required 3 ingredients!

How to Make blueberry dump cake

For this recipe, you only need 3 ingredients:

  • two 21-oz cans of blueberry pie filling
  • one 15-18 oz vanilla cake mix – I like to use the golden yellow variety for an extra buttery flavor
  • ¾ cup unsalted butter

PREP. Preheat the oven to 350° F. Get out a 9×13 inch pan, and lightly spray it with non-stick cooking spray.

(Note: You could use a ceramic or a metal pan for this recipe. I typically use a ceramic pan because I find that the blueberry layer is less likely to stick/bake onto the pan.)

ASSEMBLE. Pour the blueberry pie filling into the pan. Then, sprinkle your cake mix on top. Note that you don’t need to prepare the cake mix according to the package, just sprinkle the dry cake mix on top. Cut the butter into little pieces and place on top of the cake mix.

You don’t need to perfectly cover the cake mix with butter, because the butter will melt and ooze as the cake bakes to cover more of the pan.

BAKE. Bake for about 1 hour at 350° F.

What if I want to Use Fresh Berries?

I love it when fresh berries are in season. So if you’d like to make this recipe with fresh berries instead, you’ll essentially make your own blueberry pie filling. In a large bowl, stir together:

  • 8 cups fresh berries
  • ½ cup white sugar
  • 2 tablespoons cornstarch
  • 2 tablespoons freshly squeezed lemon juice
  • 1 teaspoon vanilla extract

Once the berries are evenly coated, spoon the mixture into the greased pan and continue with the recipe as directed – sprinkling the cake mix on top, and then proceed with the recipe as directed.

I love to serve this blueberry dump cake with fresh whipped cream, or warm with a scoop of ice cream. You could easily substitute the blueberry pie filling with cherry or really any type of pie filling for an easy, seasonal treat!

Additional recipe tips

Variations: You can use just about any pie filling you like to make this 3 ingredient dump cake! Just substitute one of the following flavors for the blueberry pie filling, and follow the instructions exactly the same.

  • Blackberry
  • Peach
  • Cherry
  • Apple

You can also switch the flavor of the cake mix! A popular combination is chocolate cake mix with cherry pie filling—Chocolate Cherry!.

Store & Reheat: Keep any leftovers in an air-tight container, or in the original cake pan covered tightly with plastic wrap, in the fridge for up to 3-4 days. Reheat individual portions in the microwave if you want to enjoy it warm.
