Blueberry dump cake is a delicious and easy-to-make dessert that combines the fruity goodness of blueberries with the sweet and buttery flavors of a cake. It gets its name from the simple preparation method, where the ingredients are “dumped” into a baking dish and baked until golden and bubbly. This dessert is perfect for those who want a quick and fuss-free dessert that still delivers on taste.

Why You’ll Love Blueberry Dump Cake

  • Best way to use seasonal fruit. Every year we are all waiting around for fresh summer fruits and what better way to celebrate summer than to use big, juicy blueberries when they’re in season? The natural sweetness of blueberries pairs perfectly with the soft, buttery cake, creating a delightful combination of flavors.
  • A cake for everyone. Blueberry dump cake is a go-to recipe for those who value convenience and simplicity in the kitchen. With just a few basic ingredients, you can have this dessert ready to bake in minutes. The “dump and bake” method eliminates the need for complex mixing or time-consuming steps, making it an ideal choice for busy individuals or beginner bakers.
  • Customizable for you. This dump cake offers plenty of room for customization, especially in the fruit department. Don’t have blueberries? How about Cherry Dump Cake instead? Or head to the tropics and make Pineapple Dump Cake!

Recipe Tips, Substitutions, and Variations

  • Do not mix the cake mix! The cardinal rule of any dump cake recipe is to NOT MIX IT! If you mix the ingredients of any dump cake recipe, it won’t bake quite right and you won’t get the consistency you’re looking for at all.
  • Can I use wild blueberries? You can. You will just have to use slightly more since regular blueberries are bigger. I would personally increase to 4 cups if using wild blueberries.
  • Fresh vs. canned vs. frozen blueberries. Fresh is obviously always preferred but you can definitely use blueberry pie filling as well. Two cans is what you’ll need. If you’re using frozen blueberries, you’ll want to thaw them and drain any excess liquid before incorporating them into the recipe.
  • Tent with foil. If you notice the top of the cake is getting dark fast, tent the top of the baking pan with foil to keep it from burning. Similarly, put the cake in the middle rack and not the top rack as heat rises and will bake the top faster.
  • Use a light colored baking dish. Dark colored baking dishes cook everything a lot faster so try to choose a light colored baking dish for even baking.
  • Try different fruits. Cherry, pineapple, oh my! The possibilities are endless with dump cakes!

Storage and Reheating Instructions

In an airtight container in the refrigerator, this blueberry dump cake will stay fresh for up to 4 days.

Keep in mind that it’s meant to be served warm, so be sure to reheat the cold leftovers for about 30 seconds in the microwave before you dig in! And if you’re like me, you’ll want to toss a scoop of ice cream in that warm bowl before digging in.

How to Serve Blueberry Dump Cake

Serve blueberry dump cake with a big ole scoop of Cookies and Cream Ice Cream or Strawberry Ice Cream. If you’ve got leftover Strawberry Cake Filling, it would be a great berry addition to this dump cake!

    Is there a reason why you use an 8×8 pan here (using 1 box of cake mix), while on your cherry dump cake you use a 9×13 pan?

      no reason, just two different ways of doing it!
