Peach Dump Cake Crisp is the kind of dessert I make when I want something warm and sweet with almost zero effort. It’s part dump cake, part crisp, with juicy peaches underneath and a buttery, oat-y topping that bakes up golden.
I like this version because the cake mix topping doesn’t turn into a flat layer—it stays a little craggy and crisp on top, especially with oats mixed in. The filling tastes like peaches and cinnamon first, not just sugar, and a little lemon keeps it from tasting heavy.
This is one of my go-to desserts for weekends, potlucks, and anytime I’m already cooking and want dessert to take care of itself. For me, it’s best served warm with vanilla ice cream and nothing fancy.
Why You’ll Love This Recipe
Fast and Easy: It’s the classic “dump-and-bake” idea, but with a crisp topping that actually has texture.
Real Crisp Top: The oats and brown sugar help the cake mix bake up with a crunchy, buttery top instead of a smooth crust.
Juicy Peach Filling: Canned peaches make it easy, and the cinnamon, lemon, and vanilla make the filling taste more like a homemade peach cobbler.
Great for a 9×13: It’s the right size when you’re feeding a group, and it holds up well for seconds.
Easy to Tweak: Use juice-packed peaches, add nutmeg, or throw in pecans if you want more crunch.
Ingredients You’ll Need
Peach Filling
- Sliced peaches (canned): I use canned sliced peaches when I want this to be truly easy. Peaches in juice work if you want it a little less sweet.
- Lemon juice: Don’t skip this. It keeps the peach filling tasting bright and not flat.
- Vanilla extract: Just enough to make the filling taste more dessert-like. Regular pure vanilla is great, but imitation works in a pinch.
- Ground cinnamon: Cinnamon and peaches are always good together here. It also makes the kitchen smell like a proper baked dessert.
- Brown sugar: A little extra gives the peaches a more caramel-y taste, especially around the edges.
- Salt: A small pinch helps the fruit taste more peachy and less syrupy.
Crisp Topping
- Yellow cake mix: This is the shortcut that makes the topping easy and reliable. Yellow cake mix gives the most classic “cobbler-ish” flavor.
- Old fashioned oats: I like old fashioned oats best because they stay chewy and crisp. Quick oats work, but the topping is a little softer.
- Brown sugar: This helps the top brown and gives that crisp, crunchy bite. Dark brown sugar is fine too.
- Unsalted butter: Melted butter is what turns the dry mix into a crisp topping instead of a powdery layer. If you only have salted butter, just go lighter on added salt.
- Ground cinnamon: A little more cinnamon in the topping makes the whole thing taste more like a crisp than a cake.
- Salt: Another pinch here matters. It keeps the topping from tasting one-note sweet.
Optional
- Ground nutmeg: If you like warm spice, nutmeg is nice with peaches. I keep it light so it doesn’t take over.
- Chopped pecans: Pecans make the top crunchier and a little more “crisp-like.” Walnuts work too.
- Vanilla ice cream: I know it’s optional, but for me it’s the best way to serve this. The cold ice cream with the warm peach filling just works.
Recipe Instructions
- Preheat the oven: Heat the oven to 350°F and grease a 9×13-inch baking dish.
- Mix the filling: Add the peaches with their juice to the baking dish, then stir in the lemon juice, vanilla, cinnamon, brown sugar, and a pinch of salt. Spread the peaches into an even layer.
- Mix the topping: In a bowl, mix the dry cake mix, oats, brown sugar, cinnamon, and a pinch of salt until combined.
- Add the topping: Sprinkle the dry topping evenly over the peaches, covering the fruit as much as you can.
- Add the butter: Drizzle the melted butter evenly over the top. Lightly pat the surface to help moisten the dry mix, but don’t stir it into the fruit.
- Add nuts: Sprinkle chopped pecans over the top if you’re using them.
- Bake: Bake for about 40 to 50 minutes, until the edges are bubbling and the top is deep golden brown.
- Cool: Let the dump cake crisp cool for 10 to 15 minutes so the filling sets up a bit before serving.
- Serve: Scoop and serve warm, with vanilla ice cream or whipped cream if you like.
Some of my tips!
This is the part that really makes a difference. If you only read one section, make it this one because this is where I share the little trick that helps the recipe turn out so well.
Recipe Tips & Tricks
Drain a little liquid if your peaches are very syrupy. If you use peaches in heavy syrup, the filling can get a little too loose. I’ll sometimes pour off about a cup of the liquid before mixing in the flavorings.
Drizzle the butter as evenly as you can. Dry pockets of cake mix can happen if the butter misses spots. I do a slow drizzle all over, then gently pat the top to help it absorb.
Don’t stir the topping into the fruit. This one matters for texture. Keeping the topping on top is what gives you that crisp, golden layer instead of a cakey, mixed-in top.
Bake it on a sheet pan. Peach desserts love to bubble over the edges, especially in a fuller 9×13. A sheet pan underneath saves you from burnt sugar drips on the oven floor.
Pull it when the top is deep golden. Pale topping usually means it’ll be a little floury. If the edges are bubbling and the top is browned, you’re in a good spot.
Make some touches!
There are plenty of easy ways to serve this depending on the occasion. Keep it simple, or add a few small touches to make it feel a little more special.
Serving Suggestions
- Ice cream: Serve it warm with vanilla ice cream on top. The ice cream melts into the peaches and it’s hard to beat.
- Whipped cream: A big spoonful of whipped cream keeps it simple. I like it when I don’t want the extra richness of ice cream.
- Extra fruit: If you have fresh berries around, a handful on the plate is nice. Raspberries in particular cut through the sweetness.
- Caramel sauce: A light drizzle is good if you want it more like a fair-style dessert. I’d keep it minimal since the topping already has brown sugar.
Save it for later
This section covers how to store leftovers and what parts of the recipe you can prepare ahead of time.
Storage and Make Ahead
Store leftovers covered in the fridge for up to 4 days. Once it’s cooled, I usually just cover the baking dish tightly and keep it chilled.
Reheat individual portions in the microwave for an easy treat, or warm the whole pan in a 350°F oven until heated through. The oven keeps the topping crispier.
You can also make this recipe ahead by mixing the dry topping and keeping it covered until you’re ready to bake. I prefer assembling right before baking so the topping stays dry and bakes up crisper.
If you want them to last longer, you can freeze individual portions. Thaw in the fridge overnight, then warm up before serving.
A few quick answers
This section covers a few extra details that may help before you head to the recipe card.
Recipe FAQs
Can I use fresh or frozen peaches instead of canned?
Yes. Use about 6 to 7 cups sliced fresh peaches (peeled if you want) or thawed frozen peaches. Add 1 tablespoon cornstarch to help the filling thicken as it bakes.
Do I need to drain the canned peaches?
Not always. If you use peaches in juice, I usually keep the liquid, but you can drain about a cup if you want the filling thicker and less sweet.
Why do I have dry cake mix spots on top?
That usually means the butter didn’t reach those areas. Next time, drizzle the butter more slowly and evenly, and lightly pat the top so the dry mix makes contact with the butter.
How do I know when it’s done?
Look for bubbling around the edges and a top that’s deep golden brown. The filling will still look a little loose when it’s very hot, but it thickens as it cools for 10 to 15 minutes.
Can I add nuts or extra spice?
Definitely. Pecans or walnuts add a nice crunch, and a small pinch of nutmeg is good if you like more warm spice in the filling.
