What is it with dump cakes??

The thing with dump cakes, the number one rule is DO NOT STIR THEM. That’s it! Dump means just that you layer on the ingredients and bake it up. The resulting dessert is kinda like a cobbler, kinda like a cake, and basically just a delicious dessert!

Our Favorite easy dump cake recipes

This is a blueberry version of our favorite dump cakes. On my site, you can find other yummy dump cakes such as this Pumpkin Crunch Cake with luscious pecans and crispy bits. What I call a Magic Rhubarb Cake is just a rhubarb dump cake but it makes rhubarb taste phenomenal! Strawberry Dump Cake, and Cherry Dump Cake round out our recipe offerings.

What do you need to make this recipe

  • Frozen blueberries OR fresh Blueberries
  • complimentary jello flavor, I used blueberry
  • lemon zest
  • yellow cake mix, dry cake mix, do not make the cake batter
  • melted butter, not cold butter
  • water
  • 9×13 cake pan OR 2.5-quart baking dish or casserole dish, I used this Made-In Oval Baking Dish

No Added Sugar

This cake is sweet enough with berries, cake mix, and a jello packet, so you don’t need to add any extra sugar. A lot of dump cake recipes call for added sugar and I find they’re too sweet. So I make all of mine without added sugar.

If you’re worried about sour berries you can always sprinkle a little sugar in with the jello powder over the blueberry layer.

Fresh fruit or frozen for dump cakes?

For this easy dessert, you can use fresh or frozen! I prefer to use frozen berries because we like to eat fresh berries when we get them. And it doesn’t make a lot of difference in the finished product.

One thing I don’t recommend (and personally don’t like) is using canned blueberry pie filling. It’s too sweet and, to me anyway, doesn’t taste good because the sweetness overwhelms everything else.

White cake mix or yellow cake mix?

Either will work. Honestly use what you have on hand. I had a yellow cake mix this time, I’ve also used white. You can also try using a lemon cake mix or a strawberry cake mix for an interesting twist!

There’s dry cake mix on my dessert!

No worries! That’s kind of the charm of these desserts. Because you’re not stirring up you will get some dry spots. If you have some dry spots no worries it is safe to eat, because you’ve baked it in the oven.

What to serve with this dessert

All the good old standbys work. Try a scoop of vanilla ice cream, whipped cream, and even cool whip served on top or alongside this delicious cake. Or go old school and drizzle on heavy cream.

A hot cup of coffee is always good with dessert. Or a big glass of cold milk.

Got leftovers?

You can cover any leftovers of this cake with plastic wrap and store it right in the pan. Or you can transfer the leftovers to an airtight container are store them in the fridge. You can store the cake at room temperature for 1-2 days and then after that, it should be refrigerated.
