This oven-baked peach dump dessert is what happens when you’ve got frozen peaches and zero desire to make a real crust. Five ingredients, one dish, and it comes out tasting like you put in way more effort than you did — juicy peaches under a golden, buttery, craggy topping that’s somewhere between a cobbler and a crisp. It’s a keeper.
Why You’ll Love It
Only 5 ingredients — sugar, flour, cinnamon, butter, and frozen peaches, that’s it
No thawing required — the peaches go in straight from the freezer, rock-hard and all
One dish, no mixer — just a bowl, a spoon, and a casserole dish
Tastes like summer — warm cinnamon-peach filling with crispy, buttery edges
Great leftovers — honestly just as good the next day, eaten cold or rewarmed
About the Ingredients
The peaches: I use them totally frozen, still rock-hard, right from the bag. Don’t thaw them. I Know it feels wrong. It isn’t. They release their juice slowly as they bake and you end up with this concentrated, syrupy situation under the topping that would not have happened the same way if you’d thawed them first. Trust me on this. Or don’t — but then don’t come back and say the bottom was watery.
Sugar: plain granulated white sugar is what you want here. I’ve tried brown sugar and it makes the topping damp in a weird way. Brown sugar has its place. This is not it.
Flour: just regular all-purpose. Nothing fancy.
Cinnamon: I put in a full teaspoon and I’d honestly go a little more next time. Maybe a teaspoon and a quarter. I like a lot of cinnamon and I’ve probably calibrated the world to assume everyone does.
Butter: unsalted, Melted, half a stick. Do not try to use margarine. I have opinions about margarine and I’ll spare you all of them except this one.
Ingredients
4 cups frozen raw peach slices — rock-hard, straight from the bag, do not thaw
1 cup granulated white sugar
1 cup all-purpose flour
1 teaspoon ground cinnamon (or a little more, honestly)
½ cup unsalted butter, melted — that’s one stick
5-Ingredient Baked Peach Dump Dessert
Let’s Make It
Preheat your oven to 350°F. Dig out a 2-quart glass casserole dish. Do not grease it. The butter takes care of everything.
Dump the frozen peaches straight in. I mean straight from the bag, frost and all. Don’t arrange them or anything. Just spread them roughly flat and move on.
In a bowl, whisk together the sugar, flour, and cinnamon. Then pour the melted butter over everything and stir it around until you get this clumpy, moist, almost sand-castle kind of mixture. It’s not a batter exactly — it shouldn’t pour. If it pours, something went sideways. It should be thick and clumpy and slightly crumbly.
