I discovered dump cake on a summer afternoon when I had fresh peaches and blueberries on the counter and wanted dessert without turning it into a project.
The name is a little unglamorous but the result is anything but — bubbling fruit, a golden buttery topping, and enough warmth and sweetness to make everyone at the table happy.
I’ll show you exactly how to layer everything so the topping comes out right and the fruit underneath stays jammy and full of flavor. It comes together in minutes and bakes into something that tastes far more effortful than it actually is.
It’s become my go-to when I want a crowd-pleasing dessert with almost no work involved.

Serves: 6 people
This recipe comfortably serves six people, making it perfect for family desserts or small gatherings. You can easily double the ingredients and bake in a larger dish if you’re serving a bigger crowd.
Ingredients You’ll Need
- 2 cups sliced peaches (fresh, canned, or frozen)
- 1 1/2 cups blueberries (fresh or frozen)
- 1/2 cup granulated sugar
- 1 teaspoon lemon juice
- 1 box (15.25 oz) yellow cake mix
- 1/2 cup unsalted butter, melted
- 1/2 teaspoon ground cinnamon (optional)
Pro Tips
If using canned peaches, be sure to drain them well to prevent excess liquid in the dish. Too much moisture can make the topping soggy instead of crisp.
Spread the fruit evenly in the baking dish so every portion has a balanced mix of peaches and blueberries. This ensures consistent flavor in every serving.
When adding the cake mix, sprinkle it evenly over the fruit without stirring. This helps create the signature layered texture that dump cakes are known for.
Drizzle the melted butter as evenly as possible over the cake mix to ensure proper browning. Any dry spots may remain powdery if not covered with butter.
For extra flavor, add a pinch of cinnamon or even a little vanilla extract to the fruit layer. These small additions can enhance the overall warmth of the dessert.
Serve the cake warm for the best texture and flavor, especially with a scoop of vanilla ice cream. The contrast between warm cake and cold ice cream is especially satisfying.
Tools You’ll Need
- 9×13-inch baking dish
- Measuring cups and spoons
- Mixing bowl
- Spoon or spatula
- Knife
- Cutting board
Substitutions and Variations
You can swap peaches with nectarines or even mango for a slightly different flavor profile. These fruits maintain a similar texture and sweetness when baked.
If blueberries aren’t available, try using raspberries, blackberries, or a mixed berry blend. Each option adds its own unique twist while keeping the dessert vibrant.
For a lower-sugar version, reduce the added sugar or use a sugar substitute that measures like regular sugar. The natural sweetness of the fruit still shines through.
You can use a white or butter cake mix instead of yellow for a slightly different flavor. Each variation works well and gives the dessert a new dimension.
For a richer version, add chopped nuts like pecans or walnuts on top before baking. This adds a crunchy texture that pairs nicely with the soft fruit layer.
Make Ahead Tips
Peach blueberry dump cake is a great dessert to prepare ahead when you want to simplify your schedule without sacrificing flavor. You can assemble the entire dish a few hours in advance, cover it tightly, and store it in the refrigerator until you’re ready to bake.
If you prefer, you can also prepare just the fruit layer ahead of time and keep it chilled separately. When ready to bake, simply add the cake mix and melted butter to ensure the topping stays fresh and crisp.
For longer planning, this dessert can be frozen before baking, though it’s best to add the butter just before placing it in the oven. This helps maintain the proper texture and prevents the topping from becoming soggy.
Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish. This ensures the cake doesn’t stick and allows for easy serving later.
Preparing the dish ahead of time helps the process go smoothly once you start layering the ingredients. It’s a simple but important step.
Step 2: Prepare the Fruit Layer
In a mixing bowl, combine the sliced peaches, blueberries, granulated sugar, and lemon juice. Stir gently until the fruit is evenly coated.
Pour the mixture into the prepared baking dish and spread it out into an even layer. This creates the juicy base that will bubble up as the cake bakes.
Step 3: Add the Cake Mix
Sprinkle the dry yellow cake mix evenly over the fruit layer, making sure to cover all the fruit. Do not stir or mix, as the layers should remain separate.
This step forms the signature topping of the dump cake, which will bake into a soft yet slightly crisp crust. Even distribution is key for consistent texture.
Step 4: Drizzle the Butter
Slowly drizzle the melted butter over the cake mix, trying to cover as much of the surface as possible. Use a spoon to guide the butter into any dry spots if needed.
Proper coverage ensures the topping bakes evenly and develops a golden color. Any uncovered areas may remain powdery after baking.
Step 5: Bake the Cake
Place the baking dish in the preheated oven and bake for 40–45 minutes, or until the top is golden brown and the fruit is bubbling around the edges. The aroma will become rich and inviting as it bakes.
Check for even browning and rotate the dish halfway through if needed. This helps ensure a consistent finish.
Step 6: Cool and Serve
Remove the cake from the oven and allow it to cool for about 10–15 minutes before serving. This helps the layers set slightly while still keeping the dessert warm.
Serve directly from the dish, optionally topped with ice cream or whipped cream. The warm fruit and buttery topping create a comforting and satisfying dessert.
Serving Suggestions
Peach blueberry dump cake is best served warm, straight from the baking dish, where the fruit is still bubbling and the topping is perfectly golden. A scoop of vanilla ice cream melts beautifully over the top, adding a creamy contrast to the warm dessert.
You can also serve it with a dollop of whipped cream for a lighter option that still enhances the flavors. The combination of sweet fruit and airy cream makes each bite feel balanced and indulgent.
For a slightly elevated presentation, try serving it in individual bowls with a sprinkle of cinnamon or a drizzle of caramel sauce. This adds a touch of extra flavor while keeping the dessert simple.
It also pairs nicely with a hot cup of coffee or tea, making it a cozy choice for evening treats or casual gatherings. The warm, fruity flavors complement a variety of beverages.
Leftovers and Storage
Leftover peach blueberry dump cake can be stored in the refrigerator for up to four days when covered tightly or placed in an airtight container. Keeping it sealed helps maintain moisture and prevents it from absorbing other flavors.
To reheat, simply warm individual portions in the microwave for about 30–45 seconds or place the dish in a low oven until heated through. This brings back the soft, comforting texture of the dessert.
If the topping softens during storage, you can briefly reheat it in the oven to restore some of its crispness. This step helps recreate that freshly baked feel.
Freezing is also an option if you want to extend its shelf life, though the texture may change slightly after thawing. For best results, enjoy it fresh or within a few days.

Recipe FAQ
Can I use frozen fruit for this recipe?
Yes, frozen peaches and blueberries work well in this recipe and are very convenient. There’s no need to thaw them before using, but you may need to extend the baking time slightly. The texture will still be delicious and jammy.
Why is my topping still powdery?
This usually happens when the melted butter doesn’t fully cover the cake mix. Make sure to drizzle it evenly and cover as much surface area as possible. You can also gently spread butter into dry spots before baking.
Can I reduce the sugar?
Yes, you can reduce the added sugar depending on the sweetness of your fruit. If your peaches are very ripe or canned in syrup, you may not need as much. Adjust to taste while keeping balance in mind.

What size pan works best?
A 9×13-inch baking dish is ideal for even baking and proper layering. Using a smaller dish may result in a thicker dessert that requires longer baking time. Stick to the recommended size for best results.
Can I add spices or flavorings?
Yes, adding cinnamon, nutmeg, or vanilla extract can enhance the flavor of the fruit. These small additions bring warmth and depth to the dessert. Adjust based on your preference.
How do I know when it’s done baking?
