- 1/2 cup unsalted butter, melted: Pours over the cake mix to create that golden, crispy finish.

How to Make Blueberry Dump Cake Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). This ensures the oven is just right to bake your dump cake evenly and achieve that perfect golden crust we’re aiming for.
Step 2: Mix the Blueberry Base
In a mixing bowl, gently combine your blueberries, sugar, and lemon juice. This blend brings sweet and tangy flavors together, setting the juicy foundation for your cake. Spread this mixture evenly across the bottom of a greased 9×13-inch baking dish—that’s the canvas for all the wonderful flavors to unfold.
Step 3: Add the Cake Mix Layer
Next, sprinkle the dry yellow cake mix evenly over the blueberry mixture. Don’t worry about perfection here; just cover the berries completely. This layer will soak up the fruit juices as it bakes, creating a crisp yet tender topping.
Step 4: Butter It Up and Add Nuts
Drizzle the melted butter evenly all over the cake mix. This step is essential—it melts into the cake mix and crisps it up beautifully during baking. If you’re feeling fancy or love some added texture, sprinkle chopped walnuts or pecans and a pinch of cinnamon on top for that extra flavor kick.
Step 5: Bake to Perfection
Place your dish in the oven and bake for 45-50 minutes. You’ll know it’s ready when the top turns a gorgeous golden brown and you see bubbles of blueberry goodness peeking through—pure magic!
Step 6: Cool Slightly
Once baked, let your Blueberry Dump Cake cool for about 10 minutes. This resting time helps the juices thicken slightly, making each spoonful irresistibly luscious.
Step 7: Serve and Enjoy
Serve it warm for that ultimate comfort dessert experience. A scoop of vanilla ice cream or a dollop of whipped cream on the side is the perfect addition to elevate this simple cake into a crowd-pleaser.
How to Serve Blueberry Dump Cake Recipe

Garnishes
Adding garnishes isn’t just about looks—it’s about enhancing the overall experience. Fresh mint leaves add a pop of color and a refreshing hint, while dusting a little powdered sugar can give it a delightful, snowy appearance. If you want to add a touch of creaminess, a drizzle of honey or a spoonful of Greek yogurt pairs beautifully.
Side Dishes
This Blueberry Dump Cake Recipe shines brilliantly on its own but can also be complemented by light side options. A crisp green salad with a citrus vinaigrette cuts through the sweetness nicely. For a more indulgent pairing, serve it alongside creamy vanilla yogurt or silky custard for a dessert spread to impress.
Creative Ways to Present
If you want to jazz up your presentation, try serving this cake in individual ramekins or mason jars—perfect for parties or picnics. You can also add layers of whipped cream and fresh blueberries between spoonfuls to create an easy parfait. For a rustic touch, serve it directly from the baking dish with a big ice cream scoop and some toasted nuts sprinkled on top.
Make Ahead and Storage
Storing Leftovers
Leftover Blueberry Dump Cake can be stored in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen with time, making it even tastier the next day. Just be sure to bring it back to room temperature or warm it slightly before enjoying.
Freezing
You can freeze this dump cake if you want to extend its shelf life. Wrap leftovers tightly in plastic wrap and then foil, or use freezer-safe containers. Freeze for up to 2 months. When ready to eat, thaw overnight in the fridge and reheat gently.
Reheating
To reheat, pop individual portions in the microwave for about 30 seconds or warm the entire dish in a 350°F oven for 10-15 minutes. This ensures the top regains its crispness while the fruit stays warm and juicy.
