Some peach desserts ask a lot of you. Multiple bowls, careful technique, hours of waiting. And then there’s dump cake.
This Peach Dump Cake is exactly what it sounds like: dump four simple ingredients into a casserole dish, bake, and let the oven do all the work. The result is a gooey, layered dessert with sticky-sweet peaches on the bottom and a buttery, golden cake layer on top — somewhere between a cobbler and a cake, and entirely delicious.
With canned peaches and a box of cake mix as the base, this is one of the simplest peach dessert recipes you can make, and it requires almost no hands-on time at all.

Common Mistakes When Making Peach Dump Cake (And How to Avoid Them)
Mixing the Layers Together
The entire appeal of a dump cake comes from its distinct layers — fruit on the bottom, cake on top. Do not stir or mix the ingredients together as you add them. Each layer should be added on top of the previous one and left alone.
Not Covering the Cake Mix Completely with Butter
Dry spots of cake mix that aren’t covered by melted butter will stay dry and powdery after baking instead of turning golden and crisp. Pour the melted butter as evenly as possible over the cake mix layer, and tilt the dish gently if needed to help it spread and cover any dry patches.
Skipping the Draining Step for Canned Peaches
The canned peach slices need to be drained before adding them to the dish. Skipping this step adds excess liquid to the dessert, which can make the finished cake soggy instead of having that distinct, slightly gooey but structured layer.
Using White Cake Mix Instead of Yellow
While white cake mix technically works, yellow cake mix has a richer, butterier flavor that pairs much better with the sweet peach filling. This small choice makes a noticeable difference in the final flavor of the dessert.
Key Ingredients: What Makes This Peach Dessert Work
Peach Pie Filling
Canned peach pie filling forms the sticky, sweet base layer of this dessert. It’s already thickened and spiced, which means it bakes up into a gooey fruit layer without any additional effort.
Canned Peach Slices
Adding a can of drained peach slices on top of the pie filling boosts the fruit content and adds extra texture to the bottom layer. Peaches in fruit concentrate, syrup, or water all work — just make sure to drain them well first.
Yellow Cake Mix
Yellow cake mix is sprinkled dry, directly over the fruit layer, where it bakes into a golden, slightly crumbly cake topping as it absorbs moisture from the fruit below and the butter poured over top. Yellow cake mix is preferred over white for its richer, butterier flavor.
Unsalted Butter
Melted butter poured over the dry cake mix is what transforms it into a golden, baked topping. Unsalted butter is recommended because both the cake mix and the canned pie filling already contain salt, so using unsalted helps keep the overall flavor balanced.
How to Make 4-Ingredient Peach Dump Cake
This recipe truly is as simple as layering and baking. Here’s exactly how to do it:
- Preheat the oven to 350°F and grease a 9×13-inch casserole dish with butter or nonstick spray.
- Add the fruit filling — pour the peach pie filling into the dish, then add the drained canned peach slices on top. Use a spatula to spread the fruit mixture into an even layer.
- Add the cake mix — sprinkle the dry yellow cake mix evenly over the peach layer, covering it completely in a thin, even layer. Do not mix it into the fruit.
- Melt the butter — melt the unsalted butter in a microwave-safe dish in 20-second intervals, stirring in between, until completely liquefied.
- Pour the butter over the cake mix — pour the melted butter evenly over the dry cake mix layer, doing your best to cover all of it. Tilt the dish gently if needed to help the butter spread into any dry spots.
- Bake until the cake layer is firm and golden and the peach layer is bubbling around the edges, about 45 minutes.
- Serve warm — scoop generous portions while hot, just like a cobbler, and top with whipped cream.
Variations and Tips for the Best Results
Use Fresh Peaches in Summer
While this recipe is built around canned peaches for convenience, fresh peaches can be sliced and used in place of the canned peach slices during peach season for an even brighter flavor. Keep the peach pie filling for the sticky base layer.
Try It with White Cake Mix
If yellow cake mix isn’t available, white cake mix works as a substitute. The flavor will be slightly less rich and buttery, but the texture and result will still be delicious.
Add a Streusel Crunch
For extra texture, sprinkle a handful of chopped pecans or a simple oat streusel over the cake mix layer before adding the butter. This adds a pleasant crunch to contrast the gooey peach layer below.
Pro Tip: Get the Layers Right
The key to success with any dump cake is maintaining distinct layers. Fruit on the bottom, dry cake mix in the middle, butter poured over the top — in that order, without mixing. This is what creates the signature cobbler-like texture in every bite.
FAQs
Can I make this peach dump cake with fresh peaches? Yes. Sliced fresh peaches can replace the canned peach slices, especially during peach season. Keep the canned peach pie filling for the sticky base layer, since it provides the thickened, spiced sauce that ties the dessert together.
How do I store and reheat leftover peach dump cake? Cover the casserole dish with foil and store it in the refrigerator for up to 5 days. To reheat, place it back in the oven covered with foil at 350°F and check after about 10 minutes, or microwave individual servings for 30 to 45 seconds.
Why is my dump cake dry on top? This usually happens when the melted butter doesn’t fully cover the dry cake mix layer. Make sure to pour the butter as evenly as possible across the entire surface, and gently tilt the dish to help it spread into any dry corners or edges.
Can I use a different cake mix flavor? Yellow cake mix is recommended for its rich, buttery flavor that pairs perfectly with peaches, but white cake mix works as a substitute if that’s what you have on hand. Other flavors like spice cake mix can also be used for a different flavor twist.
