5-Ingredient Baked Peach Dump Dessert: The Easiest, Most Delicious Summer Shortcut

Servings: 6 | Prep time: 5 minutes | Bake time: 40–50 minutes | Total time: About 1 hour (plus 15–20 minutes resting)

Let me tell you about a dessert that sounds too good to be true. It has five ingredients. It requires no mixer, no rolling pin, no fancy techniques. You don’t even need to thaw the fruit. You just dump everything into a dish, stir a few things together, and let the oven work its magic.

This 5-Ingredient Baked Peach Dump Dessert is exactly that kind of recipe.

Frozen peaches. Sugar. Flour. Cinnamon. Butter. That’s it. No eggs. No milk. No baking powder. No complicated steps. And yet, what comes out of the oven is pure magic: sweet, tender peaches swimming in a syrupy, cinnamon-spiced juice, all topped with a golden, buttery, slightly crisp topping that tastes like a cross between a cobbler, a crisp, and a cake.

The beauty of this dessert is in its simplicity. The frozen peaches release their juices slowly as they bake, creating a luscious sauce without any added liquid. The butter, sugar, and flour come together into a crumbly, clumpy topping that bakes into something extraordinary. And the cinnamon ties it all together with that warm, cozy flavor we all crave.

Serve it warm with a scoop of vanilla ice cream, and you have a dessert that will disappear faster than you can say “second helping.”

Ground cinnamon – 1 teaspoon
Unsalted butter – ½ cup (1 stick), melted

Ingredient Notes

Why frozen peaches? Frozen peaches are picked at peak ripeness and flash-frozen, so they’re actually more consistent than fresh peaches out of season. They release their juices gradually as they bake, creating a perfect syrupy sauce. Do not thaw them first — rock-hard is exactly what you want.

Can I use fresh peaches? Yes, but with adjustments. Use 4 cups of fresh peach slices (about 4–5 medium peaches). You may need to add 2 tablespoons of water or lemon juice to the dish since fresh peaches won’t release as much liquid. Bake time may be slightly shorter.

Can I use canned peaches? I don’t recommend it. Canned peaches are already waterlogged and soft. They’ll turn to mush during baking. If that’s all you have, drain them well and reduce the sugar to ½ cup (canned peaches are packed in syrup).

Why no baking powder or eggs? This isn’t a traditional cake batter. The topping relies on butter, sugar, and flour to create a crumbly, clumpy, cobbler-like texture. No leavening is needed.

Why unsalted butter? Unsalted butter lets you control the salt level. If you only have salted butter, use it — just omit any additional salt the recipe might call for (it doesn’t call for any).

Step-by-Step Directions

Step 1: Preheat and Position the Rack

Preheat your oven to 350°F (175°C) . Place an oven rack in the center position so the topping browns evenly. If the rack is too high, the topping may burn before the peaches are done. Too low, and the bottom may scorch.

Step 2: Prepare the Baking Dish

Take out a 2-quart oven-safe glass casserole dish (about 8×8 inches square or a similar size). Do not grease it. The butter in the topping will provide enough richness, and a little sticking around the edges is actually desirable — those caramelized bits are delicious.

Pro tip: Place the casserole dish on a rimmed baking sheet before putting it in the oven. This catches any bubbling juices and saves you from scrubbing your oven later.

Step 3: Dump the Frozen Peaches

Dump the rock-hard frozen raw peach slices directly into the casserole dish. Spread them into an even layer. It’s fine if they’re clumped together or frosty — do not thaw them first. Thawing would release too much liquid too early, making the dessert watery.

Step 4: Make the Topping

In a medium mixing bowl, whisk together:

1 cup granulated sugar
1 cup all-purpose flour
1 teaspoon ground cinnamon

Whisk until no streaks of flour remain and the cinnamon looks evenly distributed throughout the mixture.

Pour the melted butter over the dry mixture. Stir with a spoon or spatula until you have a thick, slightly crumbly batter. It should be moist and clumpy, not pourable like cake batter. Think wet sand or streusel topping.

Step 5: Scatter the Topping

Using your fingers or a spoon, scatter the buttery mixture evenly over the frozen peaches. Cover as much of the surface as you can. It’s fine if a few peach pieces peek through — they’ll bubble up as they bake and create beautiful pockets of fruit.

Don’t press the topping down. Leave it loose and clumpy for maximum texture.

Step 6: Bake

Place the casserole dish (on its rimmed baking sheet) in the preheated oven. Bake for 40 to 50 minutes.

What you’re looking for:

The top is golden brown
The edges look crisp and bubbly
You can see peach juices bubbling up around the sides and through a few spots in the topping
The kitchen smells like cinnamon and caramelized peaches

If the topping is browning too quickly but the peaches aren’t bubbling yet, loosely tent a piece of aluminum foil over the dish for the remaining bake time.

Step 7: Rest Before Serving

Remove from the oven and let the dessert rest on a cooling rack for at least 15 to 20 minutes.

Why rest? This pause allows the hot juices to thicken slightly so you get saucy, syrupy peaches instead of a runny pool. If you serve it immediately, the liquid will be thin and watery. Patience pays off here.

Step 8: Serve

Spoon warm servings into bowls. Top with vanilla ice cream, whipped cream, or yogurt if desired. The contrast between the warm, gooey dessert and cold, creamy ice cream is absolutely perfect.

Variations & Tips

Add Texture

Replace ¼ cup of the flour with ¼ cup of rolled oats or finely chopped nuts(pecans or almonds work beautifully). Keep the total dry mixture at 1 cup. The oats add a chewy, hearty texture; the nuts add crunch.

Add Tartness

If you prefer a slightly tart contrast to balance the sweetness, toss the frozen peaches with 1–2 teaspoons of lemon juice before adding the topping. This doesn’t count as a pantry staple in my house, but it’s a nice upgrade.

Change the Spice

Swap the cinnamon for pumpkin pie spice (1 teaspoon)
Add a pinch of ground ginger or ground nutmeg to the dry mix
Use apple pie spice for a different warm spice profile

Adjust the Sugar

Taste your peaches (if possible) or consider their natural sweetness:

Very tart peaches – Increase sugar to 1¼ cups
Quite sweet peaches – Reduce sugar to ¾ cup
Perfectly ripe frozen peaches – 1 cup is just right

Use Other Fruits

This recipe works beautifully with other frozen fruits:

Frozen cherries – Use 4 cups frozen pitted cherries. Add ¼ teaspoon of almond extract to the topping for a cherry-almond version.
Frozen mixed berries – Blueberries, raspberries, and blackberries. Reduce sugar to ¾ cup (berries are often sweeter).
Frozen apple slices – Use 4 cups frozen apple slices. Add ½ teaspoon of nutmeg along with the cinnamon.
Frozen mango chunks – Tropical and sweet. Add a pinch of cardamom if you have it.

Make It Dairy-Free

Use melted coconut oil or a neutral vegetable oil instead of butter (½ cup). The topping will be slightly less rich and may brown a bit faster — check early, around 35 minutes.

Make It Gluten-Free

Use a gluten-free all-purpose flour blend (like King Arthur or Bob’s Red Mill) in place of the regular flour. The texture will be slightly different but still delicious.

Add a Crumble Topping

For an even crunchier, more traditional crumble topping, add ½ cup of rolled oats and ¼ cup of chopped pecans to the flour-sugar-butter mixture. This takes you from “dump dessert” to “peach crumble” territory.

Storage & Reheating

Refrigerator: Store leftovers covered in the refrigerator for up to 3 days. The topping will soften as it sits, but the flavor remains wonderful.

Reheating:

Oven (best method): 350°F for 10–15 minutes, covered with foil to prevent over-browning.
Microwave: 30–60 seconds per serving. The topping won’t be crisp, but it’s fast.
Toaster oven: 350°F for 8–10 minutes.

Freezing: This dessert freezes well for up to 3 months. Transfer cooled dessert to a freezer-safe container. Thaw overnight in the refrigerator before reheating in the oven.

Food Safety Notes (Important!)

Always bake from frozen as directed. Starting with rock-hard frozen peaches is safe and ensures they release their juices gradually in the oven. Thawed peaches can become mushy and may not heat through evenly.
Make sure the dessert is heated until the center is bubbling hot. This indicates the fruit has reached a safe, high temperature (at least 165°F in the center).
Cool the dessert for at least 15 minutes before serving to avoid burns from the hot fruit syrup. That syrup can be dangerously hot straight from the oven.
Refrigerate leftovers within 2 hours of baking. If the dessert has been left at room temperature for more than 2 hours (or 1 hour in a very warm kitchen), it’s safer to discard it rather than refrigerate.
Reheat only the portion you plan to eat. Repeated reheating can affect both texture and food safety.

Frequently Asked Questions (FAQs)

Do I really need to use frozen peaches? Can’t I just use fresh?

You can use fresh peaches, but the results will be different. Fresh peaches are less predictable — some are juicy, some are dry. If using fresh, add 2 tablespoons of water or lemon juice to the dish and reduce the sugar slightly if the peaches are very sweet. Bake for 35–45 minutes instead of 40–50.

Why is my topping not crispy?

A few possibilities:

You served the dessert too soon after baking. The topping needs a few minutes to set.
You covered the dish while it was still warm, trapping steam and softening the topping.
You used a deep dish instead of a shallow one, which traps more moisture.
You didn’t bake it long enough. Look for golden brown, not just pale.

Can I add more cinnamon?

Absolutely. If you love cinnamon, increase it to 1½ or even 2 teaspoons. You can also add a pinch of nutmeg or cardamom.

Can I make this in a 9×13-inch pan?

Yes, but the dessert will be thinner and may bake faster. Use a 9×13-inch pan and check for doneness at 30–35 minutes. The topping may be crispier since it’s spread thinner.

Can I double this recipe?

Yes. Use a 9×13-inch baking dish (or larger). Double all ingredients. Bake time may increase by 5–10 minutes. Watch for bubbling juices and a golden-brown topping.

Why do I need to put the dish on a rimmed baking sheet?

The peach juices can bubble up and overflow the sides of the casserole dish, especially if you’re using a dish that’s quite full. A rimmed baking sheet catches any drips and saves your oven from a sticky, burnt-on mess.

Can I use brown sugar instead of granulated sugar?

Yes. Brown sugar will add a deeper, molasses-like flavor and make the topping slightly softer and chewier. Use the same amount (1 cup), but be aware that brown sugar clumps more easily — break up any clumps before mixing.

My peaches were very tart. Can I add more sugar after baking?

You can sprinkle a little extra sugar over the warm dessert, but it won’t dissolve as well as sugar added before baking. Next time, increase the sugar in the topping to 1¼ cups.

What to Serve With It

Classic pairings:

Vanilla ice cream – The gold standard. The hot-cold contrast is perfection.
Whipped cream – Lighter than ice cream but still creamy.
Greek yogurt – A tangy, protein-packed option for breakfast or a lighter dessert.

Next-level toppings:

Caramel sauce – Drizzle over the ice cream.
Toasted pecans or walnuts – Adds crunch.
A sprinkle of cinnamon – For an extra pop of spice.
Fresh mint leaves – For color and a fresh finish.

For breakfast (yes, breakfast):
Spoon leftovers over oatmeal, pancakes, or French toast. Call it “peach compote” and feel fancy.

The “Dump” Dessert Explained

You might be wondering: why is this called a “dump” dessert? Because you literally dump the ingredients into the dish. No layering. No arranging. No precision. You dump the frozen peaches. You dump the topping on top. You dump it in the oven. That’s it.

Dump cakes (and dump desserts) became popular in the 1970s as an ultra-simple way to make fruit desserts using boxed cake mix and canned fruit. This version skips the cake mix entirely, using just five real-food ingredients. It’s dump dessert, elevated — but still just as easy.
