You know those recipes that sound too good to be true?
Like, you hear “dump cake” and think — okay, is this actually going to taste good, or is this one of those recipes that only works in theory?
This one actually works. Really well.
And I’m not saying that lightly, because caramel + apple + buttery cake crust is genuinely one of the greatest dessert combinations ever invented. Topped with a scoop of vanilla ice cream while it’s still warm? Game over.
The whole thing comes together in about 10 minutes of prep. You literally dump everything into a dish and let the oven do its thing. No mixing bowls, no electric mixer, no complicated steps.
Keep reading, because I’ve also got a few pro tips that will take this from good to “everyone’s asking you for the recipe.”
What You’ll Need
For the filling:
- 2 cans (21 oz each) apple pie filling
- 1 teaspoon cinnamon
- ¼ teaspoon nutmeg
- 1 jar (11 oz) caramel sauce (store-bought is totally fine)
For the topping:
- 1 box (15.25 oz) yellow cake mix (dry, straight from the box)
- ½ cup (1 stick / 113g) unsalted butter, thinly sliced into pats
- ¼ cup chopped pecans or walnuts (optional, but highly recommended)
- Pinch of sea salt flakes (for the top)
To serve:
- Vanilla ice cream or whipped cream
Tools You’ll Need
- 9×13 inch baking dish
- Spoon or spatula (for spreading)
- Knife and cutting board (for slicing butter)
- Oven mitts
That’s genuinely it. No stand mixer. No saucepan. This is a true one-dish situation.
Pro Tips
Here’s what I’ve learned from making this more times than I probably should admit:
- Slice the butter thin and cover every inch. The butter melts down and essentially “bakes” the dry cake mix into that golden, crumbly crust. If you leave gaps, you’ll have dry powdery spots on top. Nobody wants that.
- Don’t stir anything once it’s in the pan. I know it’s tempting, especially when the layers look chaotic before baking. Trust the process. The magic happens in the oven.
- Let it sit for 10-15 minutes before serving. It comes out bubbling and the caramel needs a few minutes to settle. This also prevents burning your mouth (speaking from experience here).
- Use good caramel. The caramel is carrying a lot of flavor weight in this recipe. Trader Joe’s fleur de sel caramel sauce or a homemade version will take it up a level compared to generic store-bought.
- Add the sea salt flakes right before serving, not before baking. Salt on top of the warm cake as you serve it hits completely differently than salt that’s been baked in.
Substitutions and Variations
This recipe is very forgiving, which is one of my favorite things about it.
Swap the filling:
- Peach pie filling + white cake mix = a totally different (but equally delicious) version
- Cherry pie filling works beautifully too
- Pumpkin pie filling with spice cake mix is incredible for a more fall-forward vibe
Make it nutty: Pecans, walnuts, or even sliced almonds on top add a great crunch. Toast them first if you have an extra 5 minutes.
Spice cake mix: Swap the yellow cake mix for spice cake mix and skip the extra cinnamon and nutmeg. More depth, less measuring.
Salted caramel: Add an extra pinch of sea salt to the caramel layer before baking if you like that sweet-salty contrast.
Lighter version: Use a butter-flavored cooking spray and distribute it evenly over the cake mix instead of sliced butter pats. It won’t be quite as rich, but it still works.
Make Ahead Tips
This cake actually tastes great the next day once the caramel has had time to soak into the cake layer a little.
- Make it the night before if you’re bringing it to a gathering. Cover and refrigerate, then warm individual portions in the microwave for 30-45 seconds.
- Assemble and refrigerate unbaked up to 8 hours in advance, then pop it in the oven when you need it. Just add 5 extra minutes to the bake time since it’s starting cold.

Dietary notes:
- Gluten-free: Use a certified GF yellow cake mix (Bob’s Red Mill and King Arthur both make them).
- Dairy-free: Use plant-based butter (Miyoko’s or Country Crock Plant Butter work well here).
- Lower sugar: Use a sugar-free caramel sauce and reduced-sugar apple pie filling.
Meal pairing: This works as a dessert obviously, but it also holds up as a brunch dish if you dial back the caramel a little. Pair it with a hot coffee or spiced chai and you’ve got a pretty perfect fall morning situation.
How to Make Caramel Apple Dump Cake
Prep time: 10 minutes Cook time: 45-50 minutes Serves: 10-12
Step 1: Preheat and Prep Your Dish
Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish with cooking spray or a thin layer of butter.
Step 2: Layer the Apple Filling
Open both cans of apple pie filling and dump them into the prepared dish. Spread evenly with a spoon.
Sprinkle the cinnamon and nutmeg directly over the apple layer and give it a very light stir just in that layer.
Step 3: Add the Caramel
Drizzle the caramel sauce evenly over the apple filling. Don’t be shy here. Cover as much surface area as you can.
Step 4: Add the Dry Cake Mix
Pour the entire box of dry yellow cake mix directly over the caramel layer. Spread it out evenly so it covers everything. Do not mix it in.
Step 5: Lay the Butter
Place the thin butter pats across the entire surface of the dry cake mix. Try to cover it as evenly as possible — think of it like a puzzle where you’re trying to leave no gaps.
Step 6: Add the Nuts
If you’re using pecans or walnuts, scatter them evenly over the top now.
Step 7: Bake
Place in the preheated oven and bake for 45-50 minutes, until the top is golden brown and the filling is bubbling around the edges.
Step 8: Rest and Serve
Let the cake rest for 10-15 minutes. Serve warm with a big scoop of vanilla ice cream or a dollop of whipped cream. Add those sea salt flakes right before serving.
Leftovers and Storage
- Room temperature: Cover the dish with foil and it’ll keep well at room temperature for up to 2 days (assuming your kitchen isn’t too warm).
- Refrigerator: Store covered for up to 5 days. The topping softens a bit overnight, but the flavor actually deepens.
- Freezer: Scoop individual portions into freezer-safe containers. Freeze up to 2 months. Reheat from frozen in the microwave for about 90 seconds.
- Reheating: Microwave individual servings for 30-45 seconds. Add a fresh drizzle of caramel on top after reheating if you have it — it makes a big difference.
FAQ
Can I use fresh apples instead of canned pie filling?
You can, but you’ll want to cook them down first. Peel and slice about 6 medium apples, then toss them in a pan with butter, brown sugar, cinnamon, and a splash of lemon juice until they’re soft (about 8-10 minutes). Let them cool slightly before using them in the recipe. The canned version is honestly just as good here and saves you the extra step.
My top came out dry and powdery in spots. What happened?
The butter didn’t fully cover those spots. Next time, make sure you’re slicing the butter very thin and really trying to tile it across the entire surface. You can also melt the butter and drizzle it evenly over the cake mix instead — some people find this easier to control.
Can I make this in a slow cooker?
Yes! Layer everything the same way in a 6-quart slow cooker. Cook on HIGH for 2.5-3 hours with the lid slightly ajar (so moisture can escape and the top can get a little set). It won’t be golden and crispy like the oven version, but it’s still really good.
Is yellow cake mix the only option?
Not at all. Butter pecan cake mix, spice cake mix, white cake mix, and even vanilla cake mix all work. Yellow is just the most neutral base that lets the caramel and apple flavors shine.
Can I double the recipe?
You’d need two 9×13 pans or one very large roasting pan. Baking time stays roughly the same — just keep an eye on the edges starting around 40 minutes.
Do I have to use caramel sauce from a jar?
Nope. Homemade salted caramel is incredible in this if you have it. But genuinely, a good store-bought version is completely fine and saves you 20 minutes.
Wrapping Up
If you’ve been sleeping on dump cakes, this is your sign to try one.
The caramel + apple combination is just… it. Warm, gooey, sweet with a hint of spice, and that buttery golden crust on top is something special.
This is one of those recipes that looks more impressive than the effort it takes, which makes it a sneaky MVP for potlucks, holiday gatherings, or just a random Tuesday when you want dessert without a big production.
