- Mixing bowls
- Cheese grater
- Whisk
- Fine mesh strainer (if making homemade cake mix)
- Cooking spray
Importance of Each Tool
- Baking Dish: The size of your pan affects how thick your cake will be. A smaller dish yields a thicker cake.
- Cheese Grater: This tool helps evenly distribute chilled butter into the dry mix for that perfect texture.
Ingredients
For the Cake
- 3 cups fresh or frozen blueberries (don’t thaw if using frozen)
- 16 ounces vanilla cake mix (homemade version below)
- 9 tablespoons butter (chilled)
- 1/2 cup buttermilk or milk (chilled)
For Serving
- Ice cream or whipped cream
For Homemade Cake Mix
- 1 cup granulated sugar
- 3/4 cup all-purpose flour
- 2/3 cup cake flour (see note)
- 1/4 cup nonfat dry milk powder
- 1/2 tablespoon baking powder
- 1/2 teaspoon salt
- 1 tablespoon vanilla extract

How to Make Blueberry Dump Cake
Step 1: Preheat the Oven
Preheat the oven to 325 degrees F. Lightly grease a 9X12- or 9X9-inch baking dish with cooking spray. Keep in mind that using a smaller pan will result in a thicker cake.
Step 2: Prepare the Blueberries
Add the blueberries to the pan in an even layer. Set aside while you prepare the cake mix.
Step 3: Make the Homemade Cake Mix (If Needed)
If making your own cake mix, whisk together all dry ingredients in a bowl. Sift through a fine mesh strainer to ensure even mixing. Don’t forget to reserve the vanilla for later use with buttermilk (or milk).
Step 4: Incorporate the Butter
Using a cheese grater, grate the chilled butter into the dry mixture. Toss gently until it resembles coarse sand, ensuring not to melt the butter.
Step 5: Combine Ingredients
Dump the butter-cake mixture onto the blueberries. Use your hands to toss everything together until well combined.
Step 6: Add Milk Mixture
Whisk together the buttermilk (or milk) and reserved vanilla extract if you’re using homemade cake mix. Drizzle this mixture evenly over the top of your cake.
Step 7: Bake It Up!
Bake until the batter is puffy and lightly golden brown—about 35–38 minutes for a larger pan and slightly longer for a smaller one. Avoid overbaking as it may burn on the bottom.
Step 8: Serve Deliciously
Serve warm or at room temperature with a generous scoop of ice cream or whipped cream for an unforgettable treat!

How to Perfect Blueberry Dump Cake
Perfecting your Blueberry Dump Cake can make all the difference. Here are some tips to ensure yours turns out delicious every time.
- Use Fresh Ingredients: Fresh blueberries will provide better flavor compared to older ones.
- Don’t Overmix: Mix the batter just until combined; overmixing can lead to a dense cake.
- Check Baking Time: Ovens vary, so keep an eye on your cake as it bakes. You want it golden and puffy.
- Cool Slightly Before Serving: Letting it sit for about 10 minutes before serving allows flavors to meld together beautifully.
- Experiment with Flavors: Consider adding lemon zest or almond extract for unique flavor twists.

Best Side Dishes for Blueberry Dump Cake
Blueberry Dump Cake is wonderfully versatile and can be complemented by various side dishes. Here are some great options that pair well with this sweet treat.
- Vanilla Ice Cream: The classic choice that enhances the warm flavors of the dump cake.

- Lemon Sorbet: This tart sorbet creates a refreshing palate cleanser after each bite of dessert.
Common Mistakes to Avoid
When making Blueberry Dump Cake, there are a few common pitfalls to watch out for.
- Using thawed frozen blueberries: Always use frozen blueberries directly from the freezer. Thawing them can make the cake soggy and affect the texture.
- Overmixing the batter: When combining the cake mix and butter, avoid overmixing. This can lead to a dense cake instead of a light, fluffy one.
- Skipping the greasing step: It’s crucial to grease your baking dish well. Failing to do so may result in the cake sticking to the pan, making it difficult to serve.
- Not checking for doneness: Ovens vary, so it’s important to start checking your cake a few minutes before the suggested baking time. This will help prevent overbaking and burning.
- Ignoring serving suggestions: Serving your Blueberry Dump Cake warm with ice cream or whipped cream enhances its flavor. Don’t skip this delicious step!

Reheating Blueberry Dump Cake
- Oven: Preheat your oven to 350°F (175°C). Place the cake in an oven-safe dish and cover with foil. Heat for about 15-20 minutes until warm.
