Four ingredients and five minutes of prep turn into a dessert that tastes like it took all afternoon.
I started making this dump cake when I wanted peach cobbler but didn’t have the energy for a real crust or biscuit topping. You literally just dump everything into a pan, and the oven handles the rest.
Juicy peaches bubbling underneath a golden, buttery cake topping, served warm with a scoop of vanilla ice cream melting right into it. This is the dessert people assume took real effort.
Let’s put it together.
What You’ll Need

- 2 cans (29 oz each) sliced peaches in syrup, undrained
- 1 box yellow cake mix
- 1 cup butter, sliced into thin pats
- 1 tsp ground cinnamon (optional)
- Vanilla ice cream, for serving
Just four core ingredients standing between you and a warm, fruity dessert.
Tools You’ll Need

- 9×13 inch baking dish
- Can opener
- Butter knife, for slicing butter
Pro Tips
I’ve made this dump cake enough times to know exactly what makes it turn out right.
1. Don’t drain the peaches. That syrup is what keeps the bottom moist and creates that classic cobbler texture as it bakes.
2. Spread the cake mix evenly. Dumping it in clumps leads to uneven baking, with some spots staying powdery while others brown too much.
3. Cover the cake mix completely with butter pats. Any dry spots left uncovered will stay dry and powdery instead of turning golden and slightly crisp.
4. Sprinkle cinnamon over the top before baking. This adds a warm background flavor that pairs perfectly with the peaches.
5. Let it cool for at least 10 minutes before serving. The filling is extremely hot right out of the oven, and a short rest lets everything set up slightly.
How to Make Peach Cobbler Dump Cake
Step 1: Prep the Pan
Preheat your oven to 350°F.
Pour both cans of peaches, along with their syrup, into a 9×13 baking dish, spreading evenly.
Step 2: Add the Cake Mix
Sprinkle the dry cake mix evenly over the peaches, covering the surface completely.
Step 3: Add the Butter
Place the thin pats of butter evenly across the top of the cake mix, covering as much surface as possible.
Step 4: Add Cinnamon
Sprinkle with cinnamon, if using.
Step 5: Bake
Bake for 45 to 50 minutes, until the top is golden brown and the peach filling is bubbling around the edges.
Step 6: Cool and Serve
Let cool for at least 10 minutes.
Serve warm with a scoop of vanilla ice cream.
Substitutions and Variations
- Different fruit: Swap peaches for canned cherries, apples, or a mixed fruit filling.
- Spice cake version: Use a spice cake mix instead of yellow cake mix for a warmer flavor profile.
- Nutty topping: Sprinkle chopped pecans over the butter before baking for extra crunch.
- Fresh peaches: Use fresh sliced peaches mixed with ¾ cup sugar and 2 tablespoons water in place of canned, though canned gives the classic syrupy texture.
- Dairy free: Use a dairy free butter alternative and check your cake mix for dairy ingredients.
Make Ahead Tips
This dessert is best baked fresh, but you can assemble the pan up to a few hours ahead and refrigerate it, baking right before serving.
Leftovers also reheat well, making this a great dessert to prep earlier in the day for an evening gathering.

Diet Friendly Swaps
- Gluten free: Use a gluten free yellow cake mix in place of the regular version.
- Lower sugar: Use peaches packed in juice or light syrup instead of heavy syrup.
- Dairy free: Use a dairy free butter alternative throughout.
Meal Pairing Suggestions
Serve this after a barbecue or a Sunday dinner alongside coffee or sweet tea.
It also works well for a potluck dessert table next to other classic Southern desserts like banana pudding.
Cooking Time Efficiency Tips
Use a butter knife to slice the entire stick of butter into thin pats at once, rather than cutting individual pieces as you go.
Prep the pan while the oven preheats, so you’re not waiting around once everything is assembled.
Leftovers and Storage
Store leftover dump cake covered in the fridge for up to 4 days.
Reheat individual portions in the microwave for about 30 seconds, or warm the whole pan in the oven at 300°F until heated through.
FAQ
Why is my dump cake still powdery on top after baking? This usually means some spots weren’t fully covered with butter. Make sure the pats are spread evenly across the entire surface before baking.
Can I use fresh peaches instead of canned? Yes, though you’ll need to add sugar and a bit of liquid to mimic the syrup that canned peaches provide.
Can I make this in a different size pan? A 9×13 pan is standard for this recipe. A smaller pan will need a longer bake time since the layers will be thicker.
Why is my cake topping too dry? This usually means not enough butter was used, or the peach syrup wasn’t distributed evenly under the cake mix.
Can I double this recipe for a bigger crowd? Yes, use two 9×13 pans rather than doubling in a single dish, since one large pan may not bake evenly.
