When we need an EASY dessert – dump cakes are it (especially our blueberry dump cake)!

If you’ve never made a dump cake before, it’s super easy. You simply “dump” everything into the same pan and then bake!

The fruit filling layer on the bottom is a can of luscious blueberry pie filling – extra easy. Add a cake mix and some pats of butter to create the crumbly top – still easy!! That’s it – 3 ingredients! It’s pretty similar to a fruit crisp or cobbler, and ALWAYS popular. Our kids LOVE to eat this warm with a scoop (or two) of Vanilla Ice Cream. We especially love serving this at summer BBQs and taking it to potlucks.

It’s easier than making a Blueberry Cobbler or pie, and you end up with a juicy blueberry dessert that your whole family will love.

Why we think you’ll love it:

  • Just a handful of ingredients!!! A cake mix, blueberry pie filling, and butter – and that’s it! Talk about easy.
  • Prepped in minutes. Open the cans, sprinkle the cake, and cut the butter. This intro probably took longer to read than this is to prep!
  • Thick, blueberry flavor. The pie filling is sweet and creamy, the perfect base, and a tasty complement to the buttery cake layer.

  • 2 (21-ounce) cans blueberry pie filling
  • 1 (15-18-ounce) box vanilla cake mix – or lemon cake mix or yellow cake mix

    Making this right now. Pairing the canned blueberries with lemon cake as I love that combination.
    Love me some dump cake. 😋

  2. Johno says:

    I live alone & tend to eat small. I love this recipe, but as a storage problem, I’m going cut the recipe in half.& Make individual servings in Cup Cake Cups & freeze them. I’m going to do some math to figure how much cake mix to top ea serving with, but I’ll letcha know how it turns out.

    1. Lil'Luna Team says:

      I would love to hear how it turns out!

  3. Johno says:

    Soooo, making this dump cake ………I just pour the dry cake mix over the bluberries in the pan?? I dont turn the mix into a batter 1st??

    1. Lil'Luna Team says:

      That’s correct! You just dump the blueberry pie filling, then the cake mix (dry) on top and then top with squares of butter. It’s super simple!

    This was the best dump cake ever. Served warm out of the oven with French vanilla bean ice cream. Delicious

    1. Kristyn Merkley says:

      Glad you agree!! Thank you for letting me know!

    2. Cindy says:

      Can you use frozen blueberries? This looks so good!

      1. Lil'Luna Team says:

        You’ll want to use a pie filling… so you could use frozen blueberries to make a pie filling from scratch, but I think just frozen blueberries wouldn’t taste the same or give the same result.
