Blueberry Pineapple Dump Cake

This from-scratch Blueberry Pineapple Dump Cake skips the cake mix for a homemade version of a quick and easy favorite!

Dump cakes are one of the simplest cakes around. Traditionally, they’re made by placing fruit in a baking pan and topping it with cake mix. You basically “dump” everything in a pan and bake it, hence the unfortunate name. With no mixing and very little clean-up, they are one of the quickest and easiest desserts you can make.

For those of you (like me) who prefer homemade over a mix, I am happy to tell you that this Blueberry Pineapple Dump Cake is made from scratch with no cake mix in sight. There’s just one extra step for mixing the topping, turning a crazy easy dessert into a crazy easy homemade dessert!

The end result is really part cake and part crisp. It’s not quite as sturdy as a traditional cake, but it has more structure than a crisp. Serve it as is or top it with ice cream or sweetened whipped cream.

I used a favorite fruit combination in this cake. While it might not be the first fruit pairing that comes to mind, blueberries and pineapple are one of my favorite flavor pairs. The tartness of the pineapple and the sweetness of the blueberries are perfect complements to each other.

Besides how easy it is to make, the great thing about this cake is how adaptable it is. It can be made with most any single fruit or combination of fruits you like. Swap out the vanilla extract for almond extract or lemon juice. Use a different nut or coconut for the topping. Play around with your favorite flavors and see what you can create!

No cake mix here! This sweet, tart, nutty Blueberry Pineapple Dump Cake is made from scratch. Such a great quick and easy dessert! - Bake or Break


For the filling:

  • 4 cups pineapple chunks (about 20 ounces/567g)*
  • 2 cups fresh blueberries (about 16 ounces/454g)
  • 1/4 cup (50g) granulated sugar
  • 1/2 teaspoon vanilla extract

For the topping:

  • 1 & 1/4 cups (150g) all-purpose flour
  • 1 cup (200g) granulated sugar
  • 2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 3/4 cup (170g) unsalted butter, cut into cubes
  • 1 cup (about 120g) chopped nuts, such as pecans or hazelnuts


To make the filling:

  1. Preheat oven to 350°F. Butter and flour** a 9"x 13"x 2" baking pan.
  2. Place the pineapple and blueberries in the pan in a single layer. Sprinkle with sugar and drizzle the vanilla over the top. Gently shake the pan to combine.

To make the topping:

  1. Whisk together the flour, sugar, baking powder, baking soda, cinnamon, and salt.
  2. Sprinkle the topping mixture over the fruit. Gently shake the pan to combine.
  3. Place the cubed butter evenly over the top. Sprinkle the nuts over the top.
  4. Bake 40 to 45 minutes, or until the cake is golden brown and set. The top should spring back with touched.


*I used fresh pineapple cut into bite-size pieces. If you prefer to use canned, be sure to drain the pineapple before adding it to the pan.

**Alternately, you can use a cooking spray with flour, like Baker's Joy or Pam for Baking.

For any leftover cake, seal tightly and refrigerate for up to 3 days.

    4 Comments on “Blueberry Pineapple Dump Cake”

  1. I never would have even thought of combining pineapple and blueberry until a few months ago. I made an amazing blueberry pineapple pie on Chattavore and I LOVED how it turned out. A dump cake sounds just as delicious – and easier! YUM!

  2. Love the home made cake mix , be i ng diabetic I can adjust sugar and sweetener. Can’t wait to make it

  3. The homemade cake mix sounds easy and better than shopping for a cake mix to me!!! I’m going to make this but I have to use frozen berries …should I dust them w flour or sugar first ?  
    I also have awesome frozen whole cherries on hand…what do you think?  The easy directions make me want to bake…and the topping makes me drool because I just don’t like frosting on anything with fruit.

    Thank you for posting this yummy idea.
