Tips for Making the Perfect Blueberry Dump Cake
Even though blueberry dump cake is easy to make, there are a few tips that will help you make the perfect cake every time.
- Don’t mix the cake. If you mix the cake with the blueberries, it will not cook properly. The idea is to have a crunchy top. So, if you mix it won’t be crunchy.
- Use unsalted butter. Using unsalted butter will give you more control over the saltiness of the cake. If you use salted butter, the cake may end up too salty.
- Make sure you slice the butter thin and place it all over the cake mix. The more butter on top, the better it will bake the cake mix.
- Let the cake cool before serving. Let the cake cool for about 10 minutes before serving so the filling can thicken a little.

Step-By-Step Instructions

- Preheat the oven to 350 degrees and grease a 9 x 13-inch baking dish. Add the blueberries and sugar to the dish.
- Sprinkle the cinnamon on top of the blueberries.
- Mix the blueberries, sugar, and cinnamon.
- Sprinkle the cake mix evenly over the blueberry mixture. Do not mix.
- Slice the butter and place it all over the cake. Try to spread it out as much as possible to help make the cake crusty on top.
- Bake the cake for about 45 minutes or until the top is golden brown and crusty.

Serving Suggestions for Blueberry Dump Cake
Blueberry dump cake is delicious on its own, but there are a few ways you can serve it to make it even better.
- Serve it warm with a scoop of vanilla ice cream. The warm cake and cold ice cream make a great combination.
- Top it with some fresh homemade whipped cream or Cool Whip. Whipped cream adds a light and fluffy texture to the cake that complements the blueberry filling.
- Sprinkle chopped walnuts or pecans on top. The nuts will add a crunchy texture that goes great with the soft cake and gooey blueberry filling.

Frequently Asked Questions About The Delicious Blueberry Dump Cake Recipe
Can I use a different cake mix?
Yes, you can use any flavor of cake mix you like. Chocolate, spice cake, and white cake mix are all great options. Lemon cake mix is another delicious dry cake mix to add to the blueberries. You can even add a little lemon zest to the recipe for added flavor.
Can I Use Pie Filling?
Yes, any type of pie filling will work great. There are a lot of options out there, such as apple, cherry, peach, and blueberry. If you choose to use pie filling, you will not need the sugar for this recipe.
I like to use fresh berries because it tastes better, in my opinion. But both work great.
Can I make blueberry dump cake ahead of time?
You can, but it’s going to taste fresher and more delicious when you make it just before serving.

How To Make Blueberry Dump Cake
Blueberry dump cake is the perfect dessert for the summer or any time. It's easy to make and only requires five ingredients and minimal effort.
Ingredients
- 4-6 cups of fresh blueberries
- 1/2 cup of sugar
- 1 teaspoon of ground cinnamon
- 15.25 ounces of yellow box cake mix
- 1 1/2 sticks of butter, sliced
Instructions
- Preheat the oven to 350 degrees and grease a 9 x 13-inch baking dish.
- Add the blueberries to the prepared baking dish and sprinkle with the sugar and cinnamon and stir to coat.
- Sprinkle the cake mix on top and spread out. Do not mix.
- Slice the butter thin and place on top of the cake mix.
- Add the cake to the preheated oven and bake for 45 minutes or until the top is golden brown.
Notes
Slice the butter thin and spread it all over as much as possible. The cake will bake better if the butter melts all over.
The amount of blueberries depends on how many you would like. We love them, so we add the full six cups. But four is plenty, as well.
You can store any leftovers in an airtight container or cover with some plastic wrap and keep refrigerated.
You can add a scoop of ice cream right on top for some extra sweetness.
Every once in a while, the cake mix doesn't want to bake, so you need to make sure you slice the butter thin and get it all over the cake.

My blueberries are frozen, will I only have to thaw them, or do you think they may be a bit watery ?

Hi Vickie,
I would probably thaw them and then pat them dry with a paper towel before using them.

I was thinking about a Brown Butter Glaze over the top, do you think this would work?

I think either a brown butter glaze or powdered sugar glaze would be amazing with that dish. Such a great idea!
