Blueberries are one of my favorite berries to bake with and I especially love them when they’re in season! There’s just something so unbeatable about the natural sweetness of blueberries that pairs so well with baked goods.

I find that in the summer, when blueberries are at their freshest, they’re more delicious than ever. I mean, are you even celebrating the summertime if you don’t enjoy a blueberry dessert once in a while?

If you want a sweet, summery blueberry dessert that’s no-frills and hassle-free, then congratulations! You have stumbled upon the perfect recipe for blueberry dump cake. This cake mix recipe is almost too easy to believe, but believe me when I say that it’s downright delicious. No one I’ve served this blueberry dump cake to believes me when I say it’s a cake mix recipe that requires little effort – that’s how good it is!

Dump cakes of all kind are delicious, but this one with blueberries might be my favorite. I love serving a warm bowl full of this sweet blueberry dump cake with a big dollop of vanilla ice cream. It’s what summer’s for, right?!

Ingredients

  • Blueberries – Use fresh, not frozen blueberries! Frozen blueberries will not hold their shape when baking and won’t have the same strong blueberry flavor.
  • Butter – Use unsalted butter for best results.
  • Sugar – All you need here is white granulated sugar, nothing fancy!
  • Vanilla extract – A tbsp of vanilla extract will help sweeten things even more without making the dump cake overly sweet.
  • White cake mix – One box is all that’s called for, and really and brand should be just fine.

Do I need to mix any of the ingredients?

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.

Just follow my simple instructions and resist the urge to mix at all costs! Just dump!

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.

How long will homemade blueberry dump cake stay fresh?

In an airtight container in the fridge, 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.
