This dessert is the definition of hands-off comfort food. With just three main ingredients, it is budget-friendly, forgiving, and perfect for busy days when you want something warm without a lot of fuss.

Ingredients

2 cans (21 ounces each) apple pie filling
1 box (15.25 ounces) cinnamon or spice cake mix
1/2 cup unsalted butter, melted

Optional: 1/2 teaspoon ground cinnamon, 1/2 cup chopped pecans, or a drizzle of caramel sauce.

Directions

Lightly grease the inside of a 4- to 6-quart slow cooker.
Pour the apple pie filling into the bottom of the slow cooker and spread it into an even layer.
Sprinkle the dry cake mix evenly over the apples. Do not stir.
Drizzle the melted butter evenly over the top of the cake mix.
Cover and cook on LOW for 3 to 4 hours, or on HIGH for 1 1/2 to 2 hours, until the topping is set and the apples are bubbly.
Let rest for 10 minutes before serving.

Variations

Add 1/2 cup chopped pecans or walnuts over the apples before adding the cake mix.
Drizzle 1/4 cup caramel sauce over the apple layer for extra gooeyness.
Use a yellow cake mix and add 1 teaspoon ground cinnamon to the dry mix.
Swap apple pie filling for cherry or peach pie filling for a different twist.
Top with mini marshmallows during the last 20 minutes for a gooey finish.
Make it gluten-free with a gluten-free cake mix and gluten-free pie filling.

Expert Tips

Do not stir the layers. The cake mix needs to stay on top to form a tender crust.
Use melted butter, not cold butter. It distributes more evenly over the dry mix.
Watch the moisture. If the topping looks too wet, leave the lid slightly ajar for the last 20 minutes.
Let it rest before serving. The juices thicken as it sits, giving you a spoonable dessert.
Serve warm. This dump cake is best enjoyed warm, when the apples are gooey and the topping is soft.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or in a 325°F oven with a splash of water to loosen. This dessert does not freeze well, as the topping can become mushy upon thawing.
