Skillet Peach Dump Cake That’s Buttery, Golden, and Ridiculously Easy to Make

Heads up: some links are affiliate, so I may earn a tiny commission (at no extra cost to you!) on stuff I genuinely adore. Please read my Disclosure Policy for additional information.

Four ingredients, one skillet, zero mixing. This is the dessert you make when you want something warm, golden, and bubbling with peachy goodness on the table in under an hour — and you don’t want to do any actual baking.

Dump it in, bake it, scoop it straight from the skillet. Summer comfort food doesn’t get simpler than this.

Why You’ll Love This Recipe

• Four ingredients — Peaches, cake mix, butter, cinnamon. That’s it. Nothing else.
• One pan, zero cleanup — Everything happens in the skillet, from oven to table.
• Works with canned or fresh peaches — Pantry staple or peak summer fruit — both make a delicious cake.
• Golden, crispy-edged topping — The dry cake mix absorbs the butter and peach syrup and bakes into something between a cobbler topping and a golden crust.
• The cast iron makes it better — Even heat distribution gives you perfectly caramelized edges and a crispy bottom that a regular baking dish can’t replicate.
• Ready in 50 minutes — Serve it warm with a scoop of vanilla ice cream melting into the top. That’s the move.

Ingredients

• 1 can (15 oz) sliced peaches in syrup — or 2 cups fresh peaches, sliced
• 1 box (15.25 oz) yellow cake mix, dry
• ½ cup unsalted butter (1 stick), melted
• 1 tablespoon ground cinnamon
• Vanilla ice cream or whipped cream for serving (optional but very much recommended)

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C).

Step 2: Add the Peaches

If using canned peaches, pour the entire can — fruit and syrup — directly into a 10 to 12-inch cast iron skillet. The syrup is important — it’s what the cake mix absorbs during baking and what gives you that saucy, bubbling filling underneath the topping. If using fresh peaches, slice them and arrange in the skillet.

Add 2 tablespoons of sugar and 2 tablespoons of water to compensate for the missing syrup.

Step 3: Add the Cake Mix

Sprinkle the dry yellow cake mix evenly over the peaches in a flat, even layer. Do not stir. Do not mix. Leave it exactly as it is — the layering is what makes this work.

Step 4: Add the Cinnamon

Sprinkle the ground cinnamon evenly over the top of the cake mix. It distributes through the layers as it bakes and gives the whole thing that warm, spiced aroma and flavor.

Step 5: Drizzle with Butter

Pour the melted butter as evenly as possible over the cake mix, covering as much of the surface as you can. Some dry spots are fine — they absorb the peach liquid from below during baking. Don’t stir.

Step 6: Bake

Place the skillet in the preheated oven and bake for 40–45 minutes until the top is deeply golden brown and the filling is visibly bubbling around the edges. The topping should look set and crisp, not wet or powdery.

Step 7: Cool Slightly and Serve

Let the cake rest for 5–10 minutes before serving — the filling is extremely hot straight from the oven. Scoop directly from the skillet into bowls and top with a generous scoop of vanilla ice cream or a dollop of whipped cream.

Pro Tips

Use the syrup from the canned peaches. Don’t drain it. The syrup soaks up into the cake mix from below and is what creates that golden, slightly sticky topping and saucy filling. Draining the syrup before adding the peaches gives you a dry, underdone top layer.

Don’t stir. This is the entire method of a dump cake. The distinct layers — fruit below, dry mix in the middle, butter on top — are what make it work. Stirring combines everything into a batter that bakes completely differently.

Cover dry spots with extra butter. If some patches of cake mix still look completely dry after drizzling the butter, add a small extra drizzle over just those spots. Those patches won’t cook through properly otherwise.

Cast iron is ideal but not required. A 9×13 inch baking dish works perfectly well. Cast iron just gives you slightly more caramelized edges and a crispier bottom that takes the whole thing up a notch.

Let it rest before scooping. The filling is molten hot straight from the oven. Five to ten minutes of resting makes it easier to serve and lets the filling thicken slightly so it’s scoopable rather than liquid.

Variations & Customizations

• Spiced peach version — Add a pinch of nutmeg and a pinch of cardamom alongside the cinnamon for a warmer, more complex spice profile.
• Brown butter instead of regular — Brown the butter in a small saucepan until it smells nutty and toasty before drizzling. It adds a deep, caramel-like richness that pairs beautifully with the peaches.
• Mixed fruit — Combine canned peaches with a cup of blueberries or raspberries for a mixed fruit version. The colors are beautiful and the flavors complement each other perfectly.
• Chocolate cake mix — Swap the yellow cake mix for a chocolate one for a completely different but surprisingly delicious chocolate-peach combination.
• Add chopped pecans — Scatter a handful of roughly chopped pecans over the cake mix before the butter for extra crunch and a nutty Southern flavor.
• White cake mix — A white or vanilla cake mix gives a lighter, less golden topping with a slightly more delicate flavor. Works great with fresh summer peaches.

Storage & Reheating

Method	Details
Room Temperature	Cover and store at room temperature for up to 1 day. Best eaten the day it’s made while the topping is still crisp.
Fridge	Store covered in the refrigerator for up to 3 days. The topping softens as it sits but the flavor stays great.
Reheating	Reheat individual portions in the microwave for 30–45 seconds. For larger portions, cover with foil and warm in a 300°F oven for 10–15 minutes.
Freezer	Not recommended — the texture of the topping breaks down significantly after freezing and thawing.

Frequently Asked Questions

Can I use fresh peaches instead of canned?

Yes. Slice 2 cups of fresh ripe peaches and arrange in the skillet. Since fresh peaches don’t come with syrup, add 2 tablespoons of sugar and 2 tablespoons of water to create a little moisture for the cake mix to absorb. Peak summer peaches make this absolutely incredible.

Why is my topping still powdery after baking?

Either the butter didn’t cover enough of the surface, or the peach syrup didn’t have enough liquid to absorb up through the cake mix. Make sure to use the full can with all its syrup, and cover the surface as evenly as possible with the butter. A few dry patches can also be patched with a tiny extra drizzle of butter before baking.

Can I use a different flavor of cake mix?

Yes — spice cake mix is especially good here and doubles down on the cinnamon and warm spice flavor. White, vanilla, and butter pecan all work well. Chocolate is an unexpected but delicious option if you want to mix things up.

Do I need a cast iron skillet?

No. A 9×13 inch baking dish produces a great result. The cast iron just runs hotter and more evenly which gives you more caramelization at the edges and bottom — but the cake itself is just as good in a regular oven-safe dish.

Can I double the recipe?

Yes. Use a 9×13 inch baking dish instead of a skillet and double all the ingredients. Baking time stays roughly the same — start checking at 40 minutes.
