Ingredients

This recipe’s magic lies in its simplicity. The three ingredients come together to create layers of flavor and texture that feel much fancier than they actually are.

2 cans (21 oz / 595 g each) apple pie filling: This is your juicy, flavorful base. I love using a classic apple pie filling with cinnamon and spices, but feel free to try brands you trust for quality and taste.
1 box (15.25 oz / 432 g) yellow cake mix: The dry cake mix forms that irresistibly crisp, buttery topping that bakes into a golden crust. Yellow cake mix works best for its color and flavor, but you can experiment with others if you like.

3/4 cup (170 g) unsalted butter, melted: Butter is what transforms the cake mix into a crunchy, golden topping with rich flavor. Make sure it’s melted but not browned for the perfect drizzle.

How to Make Grandma’s 3-Ingredient Apple Dump Cake

Ready to make a dessert that feels like a warm hug? Here’s how you do it, step by step. I promise it’s as easy as it sounds.

Preheat your oven to 350°F (175°C). This ensures the cake bakes evenly and the butter melts perfectly into that crisp topping.

Spread the apple pie filling evenly in a 9×13-inch baking dish. Use a glass or ceramic dish if you have one — it helps the edges cook just right. The filling should cover the bottom in a nice, even layer so every bite has that juicy apple goodness.
Sprinkle the dry cake mix evenly over the apple filling. Don’t stir! Just gently shake the dry mix over the apples. This is what makes it a “dump cake” — no mixing required.
Drizzle the melted butter evenly over the cake mix. This step is key. Pour the butter slowly in thin streams across the surface so the entire topping gets that buttery crunch.

Bake for approximately 45 minutes. You’ll know it’s done when the top is golden and crisp, and you see the filling bubbling around the edges. The smell alone will tell you it’s ready!

Once out of the oven, let it cool for about 10-15 minutes. This helps the juices settle so you don’t end up with a soupy mess when you serve. Then, grab your favorite scoop and enjoy!

Substitutions & Additions

While the beauty of this recipe is its simplicity, there are plenty of ways to make it your own. Sometimes I like to mix things up a bit, especially when I want a little extra flavor or texture.

Swap the apple pie filling: Try canned cherry, blueberry, or even peach pie filling for a fun twist. I once made a delicious rhubarb dump cake that was equally heavenly.
Use a different cake mix: Spice cake or butter pecan mixes add a lovely depth. For a lighter top, consider a yellow or white cake mix.
Add spices: Sprinkle cinnamon, nutmeg, or a pinch of ground cloves over the apple filling before topping with cake mix for a more fragrant dessert.

Nuts or oats: For extra crunch, sprinkle chopped walnuts, pecans, or old-fashioned oats over the cake mix before drizzling with butter.
Top it off: Serve with vanilla ice cream, whipped cream, or even a drizzle of caramel sauce for that perfect finishing touch.

Tips for Success

Making a dump cake is so simple, but here are some little pointers I’ve picked up that make all the difference for a perfect result every time.

Don’t stir the layers: The magic of a dump cake is in the layers baking separately, creating that crisp topping with juicy filling underneath. Stirring can make it mushy.
Use unsalted butter: This lets you control the salt level so the cake topping isn’t too salty or overpowering.
Drizzle the butter slowly: Pour in thin streams rather than dumping it all in one spot. This helps the cake mix absorb the butter evenly for a crispy crust.

Watch the baking time: About 45 minutes is ideal, but ovens vary. Start checking at 40 minutes to make sure the topping doesn’t burn.
Prep ahead: You can assemble the dump cake a few hours in advance and refrigerate it. Just bring it to room temperature before baking for best results.

How to Store Grandma’s 3-Ingredient Apple Dump Cake

If you’re lucky enough to have leftovers (which might not happen, but just in case!), here’s how to keep your dump cake fresh and delicious.

Room temperature: Cover the baking dish tightly with foil or plastic wrap and keep it on the counter for up to 1 day.
Refrigerate: Store leftovers in an airtight container or cover the dish well. It will keep for 3-4 days in the fridge. Reheat in the microwave or oven until warm before serving.
Freeze: This dessert freezes well! Cover tightly with foil and a plastic wrap layer, freeze for up to 2 months. Thaw overnight in the fridge and reheat gently.

For a cozy breakfast twist, try warming up a slice and serving it alongside my favorite fluffy lemon ricotta pancakes. The bright lemon notes pair perfectly with the sweet apple flavors.

FAQs

Can I use fresh apples instead of canned apple pie filling?

Yes, you can! Just peel and slice about 6-7 medium apples and toss them with sugar, cinnamon, and a bit of lemon juice before spreading in the pan. You might want to add a bit of cornstarch or flour to thicken the juices as it bakes.

Is it possible to make this dump cake gluten-free?

Absolutely! Use your favorite gluten-free yellow cake mix and make sure your apple pie filling is gluten-free as well. The results are just as delicious.

Can I add extra spices to the apple filling?

Definitely! Adding cinnamon, nutmeg, or even a little ground ginger enhances the warmth and cozy flavors. You can sprinkle these spices directly on the filling before topping with the cake mix.

What’s the best way to serve this dessert?

This apple dump cake is divine served warm right out of the oven with a scoop of vanilla ice cream or a spoonful of whipped cream. For an extra indulgent touch, drizzle with caramel sauce. It’s a guaranteed crowd-pleaser.

If you’re a fan of easy, homey desserts, you might also enjoy my take on an easy peanut butter cup dump cake, which combines the same dump cake simplicity with a rich, chocolatey twist.
