This overnight apple cinnamon dump cake is the ultimate easy dessert or breakfast treat. With just five ingredients and a simple overnight rest, you get tender, jammy apples under a crisp, buttery cake topping—perfect for cozy mornings or holiday brunches.

Ingredients

Scale
  • 6 medium apples, peeled, cored, and sliced (Honeycrisp, Granny Smith, or Braeburn)
  • 1 ½ teaspoons ground cinnamon
  • 1 box (15.25 oz) yellow cake mix
  • ½ cup (1 stick) unsalted butter, melted
  • Optional: ¼ cup brown sugar, packed
  • Optional: ¼ cup chopped pecans or walnuts

Instructions

  1. Prepare the apples: Peel, core, and slice the apples into ¼-inch thick slices. Place them directly into an ungreased 9×13-inch baking dish and spread into an even layer.
  2. Season the apples: Sprinkle the ground cinnamon evenly over the apple slices. If using brown sugar, sprinkle that over as well. Gently toss the apples with your hands or a spatula to coat them.
  3. Add the cake mix: Open the box of yellow cake mix and sprinkle the dry powder evenly over the apples. Do not stir it in.
  4. Drizzle the butter: Melt the butter and drizzle it as evenly as possible over the dry cake mix.
  5. Cover and rest: Cover the dish tightly with aluminum foil. Place it in the refrigerator overnight (8-12 hours).
  6. Bake: Preheat oven to 350°F (175°C). Remove the dish from the fridge and let it sit on the counter while the oven heats. Bake, covered with foil, for 30 minutes. Then remove the foil and bake for another 15-25 minutes, until the top is golden brown and the edges are bubbling.
  7. Cool slightly: Let the cake cool on a wire rack for at least 10 minutes before serving. Serve warm.

Notes

For best results, use a glass or ceramic baking dish. If using a metal pan, reduce oven temperature to 325°F (160°C) and check at 40 minutes. The overnight rest is essential for the best texture and flavor; do not skip it. If you are in a hurry, you can bake immediately, but the apples will be firmer and the flavor less developed.
