The Best Blueberry Dump Cake Recipe

We had a family gathering at our house this weekend for the fourth of July.  It was a super busy day, packed with activities. Homemade Strawberry Ice Cream was on the menu for our dessert, but by the time we needed to get the ice cream going, everyone was too tired to go to the trouble of making ice cream from scratch!

Luckily, I’d already bought the ingredients for a blueberry dump cake last month and just hadn’t gotten around to making it. I love dump cakes, so easy to make and based on the leftovers (no leftovers, lol) I am positive everyone loved this easy dessert as much as I do!

Look at all those blueberries! And that buttery, delicious cake!

Doesn’t it look amazing?  (If you’re a Blueberry fan too, I have a handful of amazing blueberry desserts here to check out.)

What Exactly is a Dump Cake Anyway?

The basic concept of a dump cake is, as a time-saving recipe, you “dump” a few ingredients into a baking or casserole dish, bake it in the oven and the ingredients transform into a scrumptious dessert.

A dump cake can be made with a variety of ingredients, but most recipes are made with a boxed cake mix and some sort of pie filling, plus butter.

I make a cherry dump cake all the time, and it’s delicious too, but I’ve decided I like the blueberry version best.  (The cherry version is made the same way as this blueberry dump cake, but with cherry pie filling instead of blueberry.)  I have also made an easy peach cobbler dump cake as well, yum!

If you’ve never had a dump cake before, you’re really in for a treat!  They’re super simple to make with hardly any prep time. The combination of the cake mix, butter, and fruit pie filling makes the cake decadent and delicious.

Blueberry Dump Cake Ingredients + Tips

(Ingredients at a glance, grab the full printable ingredient list w/ amounts and recipe instructions at the bottom of the post.)

  • Box of yellow cake mix | Any brand, as long as it is yellow cake.
  • Canned blueberry pie filling | My favorite is the Lucky Leaf Organic Blueberry Pie filling, but any blueberry pie filling will work, including homemade.
  • Can of crushed pineapple | Yes, you can leave this out, but the acidity of the pineapple really adds to the dessert.
  • Fresh blueberries | For that extra pop of blueberries on the top of the cake.
  • Butter | Salted.
  • Optional | Shredded sweetened coconut – If you don’t like coconut, you can leave it out.

How to Make a Blueberry Dump Cake

I’m not kidding when I say this amazing blueberry cake really is just dumping a few ingredients together in a pan and baking. The assembly takes all of 5 MINUTES!

  1. Spread the blueberry pie filling on the bottom of your cake pan, and top with the crushed pineapple and a handful of fresh blueberries. Evenly sprinkle the dry cake mix over the top of the fruit.
  2. Thinly slice the butter sticks and place the sliced butter pieces over the dry cake mix.
  3. Sprinkle the rest of the fresh blueberries on top of the cake mix.
  4. Bake at 375 F for 40 to 45 minutes.

Pro Tips:

  1. In the past, I’ve recommended melting the butter first and pouring it over the cake mix, but for superior results and better “butter coverage,” I now recommend slicing the butter and covering the cake mix, as shown in the photo above. The sliced butter technique just makes the dump cake turn out that much better!  (No dry spots or cake powder.)
  2. I recommend serving this dump cake warm with a scoop of vanilla ice cream. Something about the creamy sweet vanilla flavor that complements the blueberries and buttery cake topping perfectly!

Can I Use Frozen Blueberries In This Dump Cake Recipe?

This recipe is made using blueberry pie filling (that’s part of why it is so easy – you just dump the blueberry pie filling into the baking dish.) The pie filling is already sweetened. I do not recommend replacing the pie filling with frozen blueberries unless you add enough sugar to make the frozen blueberries as sweet as pie filling. 

You definitely can use frozen blueberries in place of the extra fresh blueberries sprinkled on top.  (You can also just leave out the extra blueberries as the ones sprinkled on top are more for presentation than flavor.)

Can This Dump Cake Be Frozen?

Yes, if you have any leftovers, they can be frozen.

You have two choices, freeze the entire cake or separate it into individual servings.  If freezing the entire dump cake, I recommend defrosting the frozen dump cake in the refrigerator and then reheating the individual servings in the microwave.  If you freeze individual servings, you can defrost them in the microwave at 50% power.

How Do I Store This Blueberry Dump Cake?

You can refrigerate the dump cake. It is also ok to cover with foil or plastic wrap and keep at room temperature for up to up to 24 hours.  After that, I recommend putting it in the fridge or freezer.

What Blueberry Pie Filling Is Best For This Dump Cake Recipe?

Update! (5/2019)  I made this dump cake three times in the last month for various events.  (FYI, It was devoured each time!)

One thing to note when it comes to the blueberry pie filling…  I had sent my hubby to the store for the ingredients.  He wasn’t sure which blueberry pie filling to get me, so he bought a couple of different brands (including the Walmart store brand.)  You couldn’t ask for a better way to taste test blueberry pie filling, lol.

The winner? The Lucky Leaf Organic Blueberry Pie filling was the hands-down winner for taste.  (It looks like this, and you can find it at almost all retailers.)

  1. Can you make this gluten free using a gluten free cake mix?

    1. Jamie Sanders says:

      I have not tried it, but I an sure it would be fine.

  2. I’m really excited to try this. I was given some blueberry pie filling (a thing I don’t usually buy) and so I went looking for a recipe to use it and found this.

    I’ve added two more things: a handful of quick oats, scattered over the top of the cake mix, and I grated some fresh nutmeg on top of the whole thing once it was put together.

    It’s super easy to assemble – now I’m just waiting for it to bake! I can’t wait to report back and let you know how it was (my money’s on AMAZING!)

    1. Jamie Sanders says:

      The oats and nutmeg sound like a yummy addition! We eat lots of desserts around here and this blueberry dump cake is probably still in my top 5 ever, lol.

  3. Thanks for your web-site. I use apple pie filling then add fresh or frozen blueberries. My son-in-law request for fathers day!!!

    1. Jamie Sanders says:

      Sounds delish!

  4. Love easy plus looks delicious. Can’t wait to try it.

  5. Hello I haven’t made this yet.. have a question about sugar on top.. I read it somewhere but not in the directions.. am I understanding correctly.. the last 5 minutes you sprinkle the sugar on top? Sorry maybe just me.. too early and not enough sleep..

    1. Jamie Sanders says:

      I believe a few commenters talked about sprinkling granulated sugar on top for a crunchier crust, but i have never tried that,

  6. I made this for a church group and it was devoured. The hardest part of a dump cake is slicing the butter pats but the result is fantistic!

  7. Suzanne Martins says:

    Do i have to cover before putting in the oven or can i leave it open top? Thx guys!

    1. Jamie Sanders says:

      Leave it uncovered.
