Dump cake is proof that you don’t need fancy technique to make something delicious. Just layer ingredients in a pan, bake, and watch them transform into something warm, comforting, and way better than the sum of its parts. This apple version gives you tender, cinnamon-spiced apples underneath and a buttery, crispy topping that’s somewhere between cake and streusel.
It’s the dessert you make when people are coming over in an hour. Or when you need something sweet but can’t be bothered with measuring and mixing. Or when you just want dessert without the fuss.
What You’ll Need
For the Apple Layer:
- 2 (21 oz) cans apple pie filling
- 1 teaspoon ground cinnamon
- ½ teaspoon ground nutmeg
- 1 teaspoon vanilla extract
- 1 tablespoon lemon juice
For the Cake Layer:
- 1 box (15.25 oz) yellow cake mix
- 1 teaspoon ground cinnamon
- ½ teaspoon ground nutmeg
- 1 cup (2 sticks) unsalted butter, melted
- ½ cup chopped pecans or walnuts (optional)
- ½ cup old-fashioned oats (optional, for extra texture)
For Serving:
- Vanilla ice cream
- Caramel sauce (optional)
Tools:
- 9×13-inch baking dish
- Medium bowl
- Measuring cups and spoons
- Wooden spoon or spatula
- Can opener
Preparing the Apple Layer
Preheat your oven to 350°F. Grease your 9×13-inch baking dish with butter or cooking spray.
Open the cans of apple pie filling and pour them into the baking dish.
Add the cinnamon, nutmeg, vanilla extract, and lemon juice to the pie filling. Stir gently to combine and distribute the spices evenly.
Spread the apple mixture into an even layer across the bottom of the dish.
Adding the Cake Mix
Pour the dry cake mix evenly over the apple filling. Use your hands or a spoon to spread it out, covering the apples completely. You want a uniform layer with no big gaps.
The cake mix should sit on top like a blanket. Don’t stir it into the apples. Just let it rest there.
Sprinkle the additional cinnamon and nutmeg over the cake mix.
If using nuts, scatter them evenly over the surface now.
If using oats, sprinkle them over the top. They’ll toast and add a nice textural element.
Adding the Butter
This is the crucial step. Drizzle the melted butter slowly and evenly over the entire surface. You want to saturate as much of the dry cake mix as possible.
Pour it back and forth in lines, making sure you hit all the corners and edges. The butter will soak into the cake mix and create that golden, crispy top layer as it bakes.
Some dry spots are fine—they’ll hydrate from the steam released by the apples—but aim for good coverage.
Baking
Bake for 45-50 minutes. The top should be golden brown and crispy. The edges will bubble enthusiastically as the apple filling heats up and releases its juices.
You’ll see caramelized patches where the butter has pooled. Those are flavor spots. Don’t worry about them.
The dump cake is done when the top is set and crunchy and the apples are bubbling around the edges.
Cooling and Serving
Let the dump cake cool in the pan for about 15 minutes. It will be volcanic hot straight from the oven.
Scoop portions into bowls. The bottom will be soft and jammy with spiced apples. The top will be buttery and crisp.
Serve warm with a generous scoop of vanilla ice cream. The cold ice cream melting into the warm cake is essential to the experience.
Drizzle with caramel sauce if you want to take it over the top.
This makes 12 servings.
Store leftovers covered in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 45-60 seconds or in a 350°F oven for 10-15 minutes to bring back some of the crispness.
You can assemble this in the morning and refrigerate it unbaked until you’re ready. Pull it out 20 minutes before baking to take the chill off, then bake as directed.
For a homemade touch, replace the canned pie filling with 6-7 cups of peeled and sliced fresh apples tossed with ½ cup sugar, 2 tablespoons flour, 2 teaspoons cinnamon, and ½ teaspoon nutmeg. The baking time will be the same.
Try different cake mix flavors—spice cake, butter pecan, or even caramel cake mix all work beautifully with apples.
The beauty of dump cake is that it’s nearly foolproof. As long as you cover the fruit with cake mix and drench it with butter, you’re going to end up with something warm, sweet, and comforting.
