Everyone has to have a secret dessert weapon. You know, a dish that’s easy to make, ready in no time, yet looks (and tastes) like you spent all day prepping everything.

That kind of dessert. One you keep in your back pocket for those last minute get-togethers or family gatherings.

Well, friends, say hello to my secret dessert weapon: Blueberry Dump Cake!

While the name might sound a little strange, I can assure you that this dump cake tastes almost like blueberry cobbler, but without all of the prep work.

And with just 3 ingredients — yes, THREE — you can bet that this is one of the easiest desserts that will ever grace your kitchen.

Now, I’m no stranger to dump cakes. In fact, the first time I debuted this kind of dessert was with this Slow Cooker Apple Cinnamon Dump Cake from a few years ago. After I made this version, I was hooked.

Then came this Strawberry Cinnamon Dump Cake. And now, this blueberry dump cake.

Are you noticing a pattern here? Dump cakes and I are a match made in foodie heaven. I think you’ll feel the same way, too.

And I’m not lying when I say this is pretty much the best blueberry dump cake recipe ever. I mean, 3 ingredients and virtually no prep time to make a dessert that tastes just as good, if not better, than blueberry cobbler.

The juicy, tangy blueberries and sweet, buttery, cakey topping take this dessert to a whole new level. Once you take a bite, you’ll be a dump cake lover for life. I promise!

What is a dump cake?

The name may sound a little, well, weird, but it says it all. It’s literally a cake made by ‘dumping’ ingredients together and then baking.

Ingredients in Blueberry Dump Cake

To make this 3-ingredient dump cake, you’ll need the following ingredients: 

  • Blueberries
  • Golden butter cake mix
  • Unsalted butter 

Can I Use Another Type of Cake Mix? 

Yes! My secret ingredient to make the ‘cobbler’ topping taste extra delicious is using a golden butter cake mix. It gives this blueberry cake an extra hint of buttery richness.

However, if you can’t find a butter cake mix, yellow cake mix would work just as well, too.

Can I use frozen fruit in this dump cake?

Yes! Fresh or frozen blueberries works well and I guarantee you won’t notice a difference. If you make this dump cake with frozen fruit, it makes this blueberry dump cake recipe acceptable to make year round.

I like to make this blueberry dump cake with fresh blueberries whenever I can though, because fresh berries taste so much sweeter to me. 

Should I Thaw Frozen Blueberries for Dump Cake? 

No, if making the recipe with frozen blueberries you do NOT need to thaw them first. However, you may need to add a couple minutes to the bake time. 

How to Make Blueberry Dump Cake

With this 3-ingredient dump cake, I ‘dumped’ in a layer of blueberries, followed by a butter cake mix (dry mix only, no other ingredients to make the cake), and then added sliced, unsalted butter to the top of the cake.

That’s it! You really just dump everything together and the let the oven work its magic.

How to Store Blueberry Dump Cake

I prefer to store it at room temperature. I like to store dump cake in an air tight container for up to four days.

Can you freeze dump cake?

You sure can! Simply store cake in a freezable ziploc bag or container for up to 3 months. When ready to serve, thaw, and enjoy!

How to serve dump cake

I like to serve it warm, after it’s been out of the oven for 10-15 minutes. However, you could heat it up in the microwave or eat at room temperature, too. Each way is delicious!

A big scoop of vanilla ice cream or whipped cream makes the perfect topping for dump cake recipes.

Dump Cake Variations to Try

  • It’s easy to customize a dump cake, depending on your tastes. Swap out the blueberries with your fruit of choice, such as raspberries, pineapple, or peaches.
  • Combining fruits would work beautifully, too. How about a mixed berry, cherry pineapple, or strawberry banana dump cake?
  • Want to change the flavor of the cake? Swap out the butter cake mix with french vanilla, cinnamon, chocolate, or strawberry.

So, have I convinced you to try this recipe for blueberry dump cake yet? I guarantee it’ll be your favorite summer treat and maybe, just maybe, your secret dessert weapon, too!
