Whether you’re preparing a cozy dessert for the evening, hosting guests, or craving something nostalgic, this recipe delivers big flavor with minimal steps, tasting like it took hours even though the slow cooker does most of the work.

What makes this recipe especially appealing is its simplicity. With just a few pantry staples—apple pie filling, yellow cake mix, and melted butter—you can create a warm, fragrant dessert that fills your kitchen with the aroma of fall. An optional sprinkle of cinnamon deepens the flavor, making it even more irresistible. Below, you’ll find everything needed to prepare this easy dessert, including instructions, helpful tips, and serving suggestions.

The ingredients are straightforward: two cans of apple pie filling, a box of yellow cake mix, melted unsalted butter, and optional cinnamon. These few components work together to form tender apples underneath and a golden, crisp-tender topping similar to a cobbler. Even if you make substitutions, the foundation remains the same—sweet apples, dry cake mix, and butter—to create this classic dump-and-go dessert.

To make the dump cake, start by preparing the slow cooker. Lightly grease a 5- to 6-quart cooker with nonstick spray or butter to prevent sticking. Spread the apple pie filling evenly across the bottom and sprinkle the optional cinnamon over it if you choose. Next, add the dry yellow cake mix on top, distributing it evenly without stirring, and drizzle the melted butter over the surface, allowing the topping to form properly during cooking.

Cover and cook the dessert on HIGH for 2 to 2½ hours or LOW for 4 to 5 hours, resisting the urge to lift the lid. It’s done when the top becomes golden and slightly crisp, with bubbling around the edges. Let the dump cake rest for 10–15 minutes before serving to help it set. Scoop into bowls and, if desired, finish with vanilla ice cream, whipped cream, caramel sauce, cinnamon, or chopped nuts.

For added creativity, try variations such as using cherry, blueberry, or peach pie filling; switching to a spice cake mix; adding nuts for crunch; mixing in raisins or cranberries; or lining the slow cooker with parchment for easy serving. Warm, simple, and endlessly adaptable, this slow-cooker dessert is a reliable favorite for any occasion.
