I love no-fuss desserts that highlight seasonal fruit, and this blueberry dump cake fits the bill. It tastes like a classic cobbler but skips the homemade biscuit topping — perfect when you want dessert fast.

Ingredients

Only three main ingredients are required. Pick these up at the store:

Ingredients to make blueberry cobbler with cake mix on the counter.
  • Canned blueberry pie filling: The thick syrup in pie filling helps achieve the right texture for a dump cake.
  • Boxed cake mix: Vanilla works best here to complement the blueberries, though yellow or French vanilla are fine swaps.
  • Butter: Use unsalted butter and melt it before pouring over the cake mix — this gives the best texture.
  • Optional garnishes: Serve with vanilla ice cream, whipped topping or fresh blueberries for extra appeal.

Exact amounts are in the recipe card below.

Substitutions and Variations

Want to change it up? Try these alternatives:

  • Blueberry filling: This recipe is written for canned pie filling because its syrup thickens the dessert. You can use homemade pie filling or sweetened canned blueberries, but the final consistency may vary.
  • Cake mix: Vanilla is recommended, but yellow, white or French vanilla mixes also work well.

Equipment

This is a true dump-and-bake recipe. You only need:

  • Cooking spray (or a bit of butter to grease the pan)
  • 9×13-inch baking pan
  • Small bowl or cup for melting butter

How to Make Blueberry Dump Cake

With ingredients and equipment ready, follow these simple steps:

1. Preheat the oven to 350°F. This temperature lets the dessert bake evenly without over-browning.

2. Lightly grease a 9×13 baking dish with cooking spray or butter, paying close attention to the corners.

3. Spread the blueberry pie filling in an even layer across the bottom of the pan, pushing a little into the corners so every bite has fruit.

4. Sprinkle the dry cake mix evenly over the blueberry filling. Use a measuring cup or spoon to distribute it and shake the pan gently so the mix fills any gaps.

5. Pour the melted butter over the cake mix, trying to cover as much of the surface as possible. The cake mix absorbs the butter as it bakes and forms the crisp topping.

6. Bake for 50–55 minutes, or until the top is golden brown and the blueberry filling is bubbling. The cake mix should appear mostly absorbed and evenly browned.

7. Remove from the oven and let rest for about 10 minutes before serving. Enjoy warm, at room temperature or chilled.

Serving Suggestions

Top slices with a scoop of vanilla ice cream or a dollop of whipped cream for a classic finish. Warm is my favorite, but this dessert holds up well at room temperature and tastes good cold too.

Storage

Keep the dump cake at room temperature on the first day. After that, cover and refrigerate for up to four days. Refrigerate overnight to preserve freshness.

Expert Tips and FAQs

Key tips to ensure success:

  • Grease the 9×13 dish thoroughly, especially the corners.
  • Spread the blueberry filling evenly so each serving has fruit.
  • Shake the pan after adding the cake mix to settle it into open spaces.
  • Use a liquid measuring cup to pour melted butter for more even coverage.
Can you make blueberry dump cake ahead of time?

Yes. You can bake it ahead and serve later at room temperature or warm it before serving with ice cream.

How do you store easy blueberry cobbler with cake mix?

Store at room temperature the first day, then cover and refrigerate for up to four days.

What is the difference between dump cake and cobbler?

A dump cake uses boxed cake mix for the topping, while a cobbler typically has a biscuit-style or pie-crust topping made from scratch.
