Easy Peach Dump Cake (Just 3 Ingredients!)
This easy peach dump cake comes together with just 3 simple ingredients and zero mixing required. Gooey canned peaches, buttery cake, and a golden crust make this the ultimate fuss-free dessert.
The Easiest Peach Dessert You Will Ever Make
Some recipes earn a permanent spot in your rotation not because they are fancy, but because they are reliably, effortlessly delicious. This easy peach dump cake is exactly that kind of recipe. Three ingredients, one baking dish, zero mixing, and about five minutes of hands-on time stand between you and a bubbling, golden, fruit-filled dessert that tastes like it took actual effort.
Whether you call it a peach dump cobbler, a peach cobbler dump cake, or simply "that peach thing everyone asks for," the result is the same: sweet, syrupy peaches blanketed under a buttery, crumbly cake crust that gets perfectly crisp on top and soft and gooey underneath. It is summer-in-a-pan comfort food, and it could not be simpler to pull off.
Why This Recipe Works Every Single Time
The genius of a dump cake is also its appeal. There is no creaming butter, no folding, no thermometers. You just layer the ingredients and let the oven do everything. Here is what makes each component essential:
- Canned peaches in syrup: The syrup is not just a convenience, it is the secret. It soaks up into the dry cake mix as it bakes, creating that signature gooey layer underneath a crisp crust. Do not drain it.
- Dry yellow cake mix: Poured straight from the box, the mix absorbs the fruit juices and bakes into a tender, golden topping. No eggs, no oil, no mixing required.
- Cold sliced butter: This is the most important part of the technique. Thin, evenly spaced butter slices melt down through the dry cake mix, creating pockets of richness and encouraging that beautiful bronzed crust on top.
A pinch of cinnamon is optional but genuinely transforms the flavor, tying the peaches and cake together with a warm, spiced note.
Using the right baking dish and a quality butter brand genuinely makes a difference in how evenly this bakes and how golden that top layer gets. These are the tools and pantry staples worth having on hand:
Canned vs. Frozen Peaches: Which Should You Use?
Both work beautifully, and knowing the difference helps you plan ahead.
Canned peaches are the classic choice for a 3 ingredient peach cobbler dump cake. They are available year-round, they bring their own sweetness in the syrup, and they require zero prep. Grab two large 29-ounce cans and you are ready.
Frozen peaches are a wonderful option when fresh peaches are in season and you have sliced and frozen them yourself, or when you want a slightly less sweet result. Thaw them completely, keep every drop of juice, and add a tablespoon or two of sugar to compensate for the missing syrup.
Chef's Tip: If you want a deeper, more complex flavor, stir a teaspoon of vanilla extract and a tablespoon of brown sugar into your peaches before spreading them in the dish. It takes 30 extra seconds and makes a noticeable difference.
Fresh peaches can also work in summer, peeled and sliced, with a quarter cup of sugar and a splash of juice or water to create enough liquid for the cake mix to absorb properly.
Tips for the Best Peach Dump Cake Crust
The crust is everything in a 4 ingredient peach dump cake (or 3, if you skip the cinnamon). Here is how to nail it:
- Slice your butter thin. About a quarter inch thick works perfectly. Thicker slices leave gaps and dry spots.
- Cover as much surface as possible. Overlap the slices slightly if needed. Every patch of dry cake mix that gets touched by butter will bake up golden. Every patch that does not will stay pale and powdery.
- Check at the 45-minute mark. Ovens vary. If you see stubborn dry white spots, add a few extra butter pats and give it another 5 to 10 minutes.
- Let it rest before serving. Ten minutes out of the oven allows the filling to set up slightly, making it much easier to scoop and serve cleanly.
Chef's Tip: Serve this warm, not hot. The flavors bloom more fully once it has had a few minutes to settle, and vanilla ice cream melts at a more satisfying pace on a slightly cooled surface.

Easy Peach Dump Cake (Just 3 Ingredients!)
This easy peach dump cake comes together with just 3 simple ingredients and zero mixing required. Gooey canned peaches, buttery cake, and a golden crust make this the ultimate fuss-free dessert.
Ingredients
- 2 cans canned peaches in syrup, 29 oz each, do not drain
- 1 box yellow cake mix, standard 15.25 oz box, dry and unprepared
- 3/4 cup unsalted butter, cold, cut into thin slices
- 1 tsp ground cinnamon, optional but highly recommended
Instruction
Preheat your oven to 350 degrees F (175 degrees C). Lightly grease a 9x13-inch baking dish with butter or nonstick spray.
Pour both cans of peaches, including all the syrup, directly into the prepared baking dish and spread them into an even layer.
Sprinkle the ground cinnamon evenly over the peaches if using.
Open the dry cake mix and pour it straight from the box over the peaches. Spread it into an even layer with a spatula or the back of a spoon. Do not stir.
Lay the cold butter slices in a single layer across the top of the cake mix, covering as much surface area as possible. The more coverage, the better the golden crust.
Bake uncovered for 45 to 55 minutes, until the top is golden brown and the edges are bubbling. If there are dry spots of cake mix showing after 45 minutes, add a few extra butter slices and bake for another 5 to 10 minutes.
Remove from the oven and let cool for at least 10 minutes before serving. Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream.
Equipment
- 9x13-inch baking dish
- Spatula or large spoon
- Sharp knife (for slicing butter)
- Oven mitts
Notes
How to Serve and Store Peach Dump Cake
This dessert is at its absolute best served warm from the oven with a generous scoop of vanilla ice cream. The contrast between the hot, bubbling peaches and the cold, melting ice cream is the whole point. Whipped cream works beautifully too, and a light dusting of cinnamon on top never hurts.
For leftovers, cover the baking dish tightly with plastic wrap or transfer portions to an airtight container. It keeps in the refrigerator for up to 4 days and reheats in the microwave in about a minute. The topping softens slightly but the flavor holds up wonderfully.
Make It Your Own
Once you have the basic peach dump cake recipe down, the variations are endless:
- Swap yellow cake mix for spice cake mix for a warmer, more autumnal flavor
- Add chopped pecans or walnuts over the butter layer for crunch
- Use white cake mix for a lighter, more delicate crust
- Stir a pinch of nutmeg into the peaches alongside the cinnamon
- Mix in a can of crushed pineapple with the peaches for a tropical twist
However you make it, this peach dump cake easy enough for a Tuesday night and impressive enough for a holiday table. Keep this one in your back pocket. You will reach for it more than you expect.
