Dump cakes get a bad name because “dump cake” sounds like something you’d apologize for serving. This one you will not apologize for. It’s peaches, cake mix, butter, and cinnamon layered in a dish with zero stirring involved, and it comes out tasting like a cobbler that took actual effort. Five minutes of hands-on work, tops, and the oven does the rest.

Ingredients for Peach Cobbler Dump Cake

• 1 (16-ounce / 454 g) can sliced peaches in light or heavy syrup (do not drain)
• ½ box yellow cake mix (about 7.5 ounces / 213 g)
• 4 tablespoons (57 g) unsalted or salted butter, cut into small pieces
• ½ teaspoon ground cinnamon, or more to taste
• Vanilla ice cream, for serving (about 4 scoops)

Kitchen Tools Needed for cake  

Steps for Peach Cobbler Dump Cake

Preheat. 

Set your oven to 375°F.

Dump the peaches.

Open the can and pour them into your baking dish, syrup and all don’t drain them. That liquid is doing real work here, bubbling up through the cake mix as it bakes.

Add the cake mix. 

Sprinkle the dry mix evenly over the top until you can’t really see the peaches underneath anymore. You’re not stirring anything, just covering. It’ll look a little strange at this point, like a layer of powder sitting on fruit, but that’s exactly right.

Add the butter. 

Cut it into small, bite-sized chunks and scatter them across the surface of the cake mix, spreading them out as evenly as you can so the butter reaches most of the top. Some dry spots might still happen  that’s fine, more on that below.

Add the cinnamon.

I’m generous here because I really love cinnamon with peaches. If you’re more conservative, start light  you can always add more once it comes out, but you can’t take it away.

Bake. 375°F for 45 minutes.

Tips for Peach Cobbler Dump Cake

Let it sit about 20 minutes after it comes out before serving. It’ll be bubbling like crazy, and you want it hot, not lava-hot, especially since the whole point is melting ice cream into it.

Some dry patches of cake mix on top, where the butter didn’t quite reach, are completely normal. It tastes fine  just scoop through it when serving and it all blends together.

Serve it while it’s still warm with a generous scoop of vanilla ice cream. That melt-into-the-peach-and-cake moment is the entire reason this recipe exists.

Variations if you want in cake 

I’ve made the blueberry version more times than I can count, usually when peaches weren’t on sale that week, and it’s just as easy and just as good  the peach one still wins for me personally, but it’s close. Cherry pie filling works too if you want something a little more tart and less syrupy; I tried that once for a holiday and it disappeared fast. Strawberries I haven’t attempted yet, mostly because my kid would eat the can straight before it made it into the dish. If you’re worried the light syrup peaches won’t be sweet enough, a light sprinkle of sugar before the cinnamon fixes that  though I’ve made it with light syrup plenty of times now and never actually needed to.

Serving Suggestions 

Warm, straight out of the dish, with vanilla ice cream on top that’s really the only way I serve this. If you’re bringing it somewhere, a scoop of whipped cream travels a little better than ice cream if you’re not eating it immediately.

Storage & Reheating Instructions

Cover and refrigerate leftovers for up to 4 days. Reheat individual portions in the microwave for 30–45 seconds before adding fresh ice cream on top  the syrup thickens a bit in the fridge, but a quick reheat loosens it right back up. I wouldn’t freeze this one; the texture of the cake layer doesn’t hold up well once it’s been frozen and thawed.

Frequently Asked Questions

I only had heavy syrup peaches on hand once does it change much?

→ Not really, I just went lighter on any extra sugar that time. It came out sweeter than my usual light-syrup version, but nobody complained.

My cake mix looked patchy and dry in spots after baking  did I mess it up?

→ No, that happens most times I make this too, usually wherever the butter chunks didn’t quite spread far enough. Just scoop down through the layers when serving and it evens out completely.

Can I use fresh peaches instead of canned?

→ I haven’t tried it myself since the whole point for me is the five-minutes-of-effort part, and fresh peaches would need to be sliced and probably pre-sweetened. If you go that route, I’d add a little extra sugar since you’d lose the syrup.

Is it too sweet with ice cream on top?

→ For me, no  but my husband thinks it’s right at the edge of too sweet, so if you’re sensitive to that, go lighter on the cinnamon-sugar side and let the peaches carry more of the flavor.

How long does it actually take start to finish?

→ About five minutes of hands-on work, then 45 minutes of baking, plus the 20-minute rest before serving. So just over an hour total, but almost none of it requires you to actually be in the kitchen.
