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 mean, are you even celebrating the summertime if you don’t enjoy a blueberry dessert once in a while?

Each bite of this dump cake is rich with fresh blueberry flavor, delicious cake mix, and buttery goodness. You’ll be hard pressed to find an easier and more delicious blueberry dessert than this one.

Ingredients You’ll Need

A short and simple ingredient list for blueberry dump cake. Be sure to scroll down to the recipe card for exact measurements.

• 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 tablespoon 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 any brand should be just fine.

How to Make Blueberry Dump Cake

As the name implies, you just gotta dump and bake. Be sure to check out the full recipe below for detailed instructions.

Set the oven. Preheat oven to 350 degrees Fahrenheit.

Prepare to dump and bake. Add the blueberries, ⅓ cup of the butter, sugar, and vanilla to an 8×8″ baking pan and stir to combine. Pour the cake mix on top then spread it out in an even layer. Pour the remaining butter on top of the cake mix and gently spread it around evenly.

Bake. Bake uncovered for 40-50 minutes or until light and golden on top.

Recipe Tips, Substitutions, and Variations

• Do not mix the cake mix! 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.
• 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.
• Fresh vs. canned vs. frozen blueberries. Fresh is obviously always preferred but you can definitely use blueberry pie filling as well. Two cans is what you’ll need. If you’re using frozen blueberries, you’ll want to thaw them and drain any excess liquid before incorporating them into the recipe.
• Tent with foil. If you notice the top of the cake is getting dark fast, tent the top of the baking pan with foil to keep it from burning. Similarly, put the cake in the middle rack and not the top rack as heat rises and will bake the top faster.
• Use a light colored baking dish. Dark colored baking dishes cook everything a lot faster so try to choose a light colored baking dish for even baking.
• Try different fruits. Cherry, pineapple, oh my! The possibilities are endless with dump cakes!

Storage and Reheating Instructions

In an airtight container in the refrigerator, 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.

How to Serve Blueberry Dump Cake

Serve blueberry dump cake with a big ole scoop of Cookies and Cream Ice Cream or Strawberry Ice Cream. If you’ve got leftover Strawberry Cake Filling, it would be a great berry addition to this dump cake!
