This gooey peach dump cake transforms juicy canned peaches into a delectable dessert with minimal effort. The warm fruit base bubbles up through a buttery, cinnamon-spiced cake layer, creating the perfect balance of sweet fruit and golden topping that's reminiscent of cobbler but requires just minutes of prep time.
I discovered this recipe during a family reunion when my aunt needed a quick dessert for unexpected guests. The looks of pure joy when everyone took their first bites convinced me this would become my go-to emergency dessert.
Ingredients
- Yellow cake mix: creates the perfect cakey topping without measuring flour, sugar, or leavening agents
- Canned peaches: provide consistent sweetness and juiciness year-round regardless of peach season
- Butter: transforms the dry cake mix into a rich, golden crust that complements the fruit perfectly
- Brown sugar: adds a caramel note that enhances the natural sweetness of the peaches
- Cinnamon: brings warmth and depth that makes this dessert feel homemade despite its simplicity
- Salt: balances the sweetness and enhances all the flavors
Step-by-Step Instructions
- Prepare Your Pan:
- Generously grease a 9×13 baking dish with cooking spray, ensuring complete coverage to prevent sticking. Preheat your oven to 350°F so it reaches the proper temperature while you assemble the cake.
- Layer The Peaches:
- Pour two cans of peaches with their juice and one drained can into your prepared pan, spreading them evenly across the bottom. The juice from two cans provides perfect moisture without making the cake soggy. Sprinkle with half a teaspoon of cinnamon to begin building the warm flavor profile.
- Mix The Topping:
- Combine brown sugar, remaining cinnamon, and salt in a bowl, stirring until evenly incorporated. This mixture will create pockets of caramelized sweetness throughout the cake as it bakes.
- Add The Cake Mix:
- Sprinkle dry cake mix evenly over the peaches, using a light touch with a spatula to create a level surface without pressing down or mixing with the fruit. This creates the characteristic layers of a dump cake.
- Add Butter:
- Cut cold butter into thin slices and arrange them across the entire surface of the cake mix, trying to cover as much area as possible. The butter will melt into the cake mix, creating a crisp, golden crust.
- Finish With Sugar Mixture:
- Sprinkle the brown sugar mixture evenly over the butter and cake mix layer to add caramelized sweetness to the top of your dessert.
- Bake To Perfection:
- Bake for 50-55 minutes until the top turns golden brown and fruit juices bubble around the edges. The bubbling indicates the fruit has released its juices and mingled with the cake mix properly.

My grandmother taught me the importance of that third can of drained peaches. When I asked why not just use all the juice, she explained that draining one can prevents the cake from becoming too soggy while still providing enough moisture for the perfect consistency. Her wisdom has never steered me wrong.
Storage and Serving
This peach dump cake keeps beautifully in the refrigerator for up to 5 days when covered tightly with plastic wrap or transferred to an airtight container. The flavor actually improves after the first day as the cake absorbs more of the peach flavor. To reheat, simply microwave individual portions for 30-45 seconds or place the entire dish in a 300°F oven for 15 minutes until warmed through.
Impressive Variations
While this classic version is perfect on its own, you can easily customize this dump cake to create exciting variations. Try mixing in fresh blueberries with the peaches for a burst of color and complementary flavor. For a tropical twist, substitute one can of peaches with crushed pineapple. During fall, try adding a teaspoon of pumpkin pie spice instead of cinnamon and topping with chopped pecans for seasonal appeal.
Serving Suggestions
This peach dump cake reaches new heights when served with a scoop of vanilla ice cream that melts slightly into the warm cake. For a special brunch offering, serve it slightly warm with a dollop of Greek yogurt and a drizzle of honey. During the holidays, try adding a splash of bourbon to the peach mixture and serving with bourbon-spiked whipped cream for an adult dessert that impresses guests with minimal effort.
The Perfect Shortcut
The beauty of dump cakes lies in their rustic simplicity. Unlike traditional cakes that require precise measuring and mixing, this dessert forgives minor variations. The method originated during the mid-20th century when convenience foods became popular, allowing home cooks to create desserts that tasted homemade with significantly less effort. This particular recipe honors that tradition while adding just enough personal touches to make it taste completely from scratch.
