Each ingredient in this recipe plays a special role in creating the perfect balance of flavor, texture, and color. They’re all simple staples, but when combined, they create something truly special that feels like more effort than it really takes.

6 cups blueberries: Fresh or frozen works beautifully, providing juicy bursts of flavor that shine as the star of this cake.
3 tablespoons granulated sugar: Just enough to sweeten the berries without overpowering their natural tartness.
2 tablespoons cornstarch: This thickens the blueberry filling perfectly so it’s luscious but not runny.
1 teaspoon pure vanilla extract: Adds a warm, fragrant depth to the filling that rounds out the tart berries.
One lemon (zested and juiced): Fresh lemon zest and juice brighten the flavor, adding a zesty kick.
1/4 teaspoon cinnamon: A subtle hint of spice that complements the blueberries beautifully without stealing the show.
1 box yellow cake mix: The secret to an easy, buttery topping that crisps up perfectly in the oven.
1/2 cup (1 stick) cold butter, cut into 1/4-inch slices: This creates that irresistible golden, flaky crust that makes every bite delightful.

How to Make Easy Blueberry Dump Cake Recipe

Step 1: Preheat Your Oven

Start by preheating your oven to 350°F. This ensures that when you’re ready to bake, the heat is just right for golden, bubbling perfection.

Step 2: Prepare the Blueberry Mixture

In a medium bowl, toss together the blueberries, sugar, cornstarch, vanilla extract, lemon juice and zest, and cinnamon. This mix will give you a rich filling with the perfect balance of sweetness and tartness, thickening as it bakes to perfection.

Step 3: Assemble the Base

Pour the blueberry mixture into a 9×13-inch baking dish that’s been lightly coated with cooking spray. This layer will be the saucy, juicy foundation of your dump cake.

Step 4: Add the Cake Mix

Evenly sprinkle the dry yellow cake mix over the fruit. This step sounds simple, but it’s key to creating that signature cake-on-top texture that’s both crisp and fluffy.

Step 5: Top with Butter

Arrange the cold butter slices evenly over the cake mix. As the butter melts, it transforms the dry cake mix into a rich, golden crust that pairs perfectly with the blueberry filling below.

Step 6: Bake to Perfection

Bake the dump cake for 1 hour, or until the top is beautifully golden brown and the filling is bubbling with blueberry goodness. Once out of the oven, let it cool for about 10 minutes—it’s worth the wait to let those flavors set and the cake to firm up slightly.

How to Serve Easy Blueberry Dump Cake Recipe

A white rectangular baking dish holds a blueberry cobbler, with one corner scooped out, showing thick, dark purple blueberry filling beneath a golden-brown, crumbly top crust. The crust is uneven with a rough texture, some spots slightly darker, and scattered fresh blueberries and green mint leaves decorate the top. A gold spoon inside the dish is coated with the juicy blueberry filling, resting on the edge of the scoop area. The dish sits on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

Garnishes

For a little extra flair, sprinkle some fresh blueberries or a dusting of powdered sugar on top before serving. A dollop of whipped cream or a scoop of vanilla ice cream is practically mandatory; the cool creaminess complements the warm, fruity cake perfectly.

Side Dishes

This dessert pairs wonderfully with a light, refreshing salad if you’re serving it at a larger gathering. For something heartier, try it alongside a scoop of creamy yogurt or even some freshly brewed coffee or tea to balance the sweetness.

Creative Ways to Present

Serve your Easy Blueberry Dump Cake Recipe in individual ramekins or mason jars for a charming, rustic touch. You can also add a sprinkle of toasted almonds or a drizzle of honey on top for added texture and flavor complexity. Presentation can be casual or dressed up depending on your occasion.

Make Ahead and Storage

Storing Leftovers

Leftover dump cake keeps well in an airtight container in the refrigerator for up to 4 days. The flavors actually deepen overnight, making leftovers just as tasty, if not better!

Freezing

You can freeze this cake by wrapping it tightly with plastic wrap and foil or storing in a freezer-safe container. It will keep well for up to 3 months. When ready to enjoy, thaw it overnight in the fridge for best results.

Reheating

Reheat individual servings in the microwave for about 30 seconds or place the whole dish in a preheated 350°F oven for 15–20 minutes until warm and bubbly again. Adding a small splash of water before reheating in the oven helps keep the cake moist.
