A Crock—Pot spiced apple dump cake is the ultimate dessert for busy days when you want something warm and comforting but do not have hours to spend in the kitchen. With just five ingredients and hands—off cooking, it is one of those dependable treats you can start before dinner and come back to the sweet aroma of cinnamon apples filling your home. Perfect for potlucks, holidays, or easy weeknight indulgence, this cake always comes out bubbling, soft in the middle, and crisp on top.
I first whipped this up after a last minute dinner guest announcement on a chilly fall evening, and now it is my go to dessert for family game nights and autumn gatherings. No one ever guesses how simple it is.
Ingredients
- Boxed Spice Cake Mix: You want a moist cake base with warming spices Look for mixes where cinnamon nutmeg and cloves are listed high in the ingredients for the best flavor
- Canned Apple Pie Filling: Choose a filling with plenty of apple slices and a glossy syrup Avoid brands with mushy apples or too much added sugar
- Unsalted Butter, Melted: This holds the topping together and creates a buttery crust Always use unsalted so you can control the saltiness
- Quick Cooking Oats: These give structure and a little chew to contrast the soft apple filling Old fashioned oats do not work as well here
- Walnuts, Chopped (Optional): But they add crunch and nuttiness Look for fresh walnuts that smell sweet not rancid
Instructions
- Mix the Topping:
- In a large bowl thoroughly blend the dry spice cake mix quick cooking oats and melted unsalted butter with a fork or spoon Keep stirring until all the dry spots are gone and the mixture looks crumbly but evenly moist
- Layer the Apples:
- Add both cans of apple pie filling to the bottom of a five to six quart slow cooker Use a spatula to spread it evenly creating a uniform layer that touches the edges This ensures every bite has apples
- Top with Crumble:
- Sprinkle the cake mix and oat topping generously over the apples Try to distribute it as evenly as possible but do not pack it down Scatter the chopped walnuts over the top if using This layer creates that crisp buttery crust on top
- Slow Cook the Cake:
- Place the lid on your slow cooker Set it to HIGH and let everything cook undisturbed for about two hours When the edge is bubbling and the top is golden brown it is done The cake should be set but still soft in the center
- Serve:
- Spoon the warm cake into bowls for gooey comforting servings For an extra treat top with vanilla ice cream or whipped cream Let it cool if you prefer firmer slices

For me the oats give this cake an extra rustic touch and remind me of my grandma’s apple crisp She loved the way the topping caramelizes against the slow cooked apples This dessert always transports me back to her cozy kitchen
