BEST Apple Dump Cake

Have you ever heard of a dump cake? It’s a super easy dessert where you “dump” all of your ingredients into a pan and bake it. Or, in the case of this apple dump cake I’m sharing, you dump everything in your crockpot. It’s one of the easiest desserts ever.

There are a thousand ways to make a dump cake – they’re usually made with fruit and cake mix – and for fall there’s nothing better than this crockpot apple cake recipe. I love apple recipes and it’s just as delicious as an apple crisp or apple crumble but easier to make.

Six Ingredients in Dump Cake

  • Apples: I like Granny Smith apples best, the tart with the sweet. They are also sturdy enough they don’t get mushy in the crockpot.
  • Granulated Sugar: To sweeten the apples
  • Cinnamon: Can’t have apple desserts without cinnamon!
  • Yellow Cake Mix: This is the magic of a dump cake – dumping in the cake mix!
  • Oats: Quick oats or old-fashioned oats make this more of a crumble
  • Sliced Butter: The butter melts as the cake cooks creating that crumbly top.

You know how you can tell when fall is coming? There’s a change in the air and as soon as that happens, I am getting the slow cooker out to make this dump cake. It’s my favorite summer-to-fall transition dessert.

(Well, that turn in the air comes with 100 degree days mixed in but I make it anyway!)

How to Prep Apples for Cake

I usually use five to seven apples for this recipe. I love Granny Smith because they are really tart and hold their shape even after cooking for several hours.

If your apples are big you can use less, but the recipe is pretty forgiving so don’t stress it too much!

Because I am apple obsessed, I use an apple peeler tool that makes peeling and coring the apples really easy. But, you can also do it by hand:

  • Use a vegetable peeler to remove the skin
  • Cut the apples into quarters and then, using a paring knife, cut the cores out.

How to Make Apple Dump Cake

1. Apples: Once you’ve peeled, cored, and diced your apples just pile them in the slow cooker. Sprinkle the cinnamon and sugar over the top.

2. Dump: Pour the cake mix and oats into the slow cooker so they are cover the apples.

3. Butter: Place the sliced butter in an even layer over the top of the cake mix and oats.

4. Cook: Secure the lid and cook the cake for four hours on high. That’s it. Easiest crockpot apple cake ever.

Tips for Making Crockpot Dump Cakes

  • First rule of crockpots is that all crockpots are different! Depending on your model this cake may take more or less time.
  • The first time you make this, I recommend checking on the cake after 1 ½ hours of cooking time just in case your slow cooker runs hot.
  • You can tell when the cake is done when all the butter is melted and the cake mix doesn’t look like powder. The top of the cake should be golden brown.
  • To keep the moisture in balance, sometimes I place a paper towel between the lid and the insert which will absorb a lot of the condensation early in the cooking time. After two hours I remove it so the liquid that is created inside the crockpot will dissolve the cake mix.

After you’ve tried this recipe, you’ll know how it will bake and if it needs more or less time.

Homemade Cake Mix vs Boxed Cake Mix

What makes this such an easy dessert is using cake mix, but I understand if that’s not your thing! You could try using homemade yellow cake mix, but (full disclosure!) I’ve never tried it, but a few readers have with success!

How to Serve Apple Dump Cake

Grab a serving spoon and scoop it into bowls! It’s delicious just as it is, but here are some ideas to dress it up:

  • Add a scoop of vanilla ice cream on top. As it melts it will mix with all of that apple goodness!
  • A dollop of whipped cream is delicious, too.
  • Add a drizzle (or whole glug!) of salted caramel sauce for an extra-decadent treat.
  • Keep it simple and dust each serving with some powdered sugar.

I think once you try this crockpot apple cake dump cake it will quickly become a family favorite! My family requests it every year and I usually make it on repeat all through the fall season. I hope you love it!

Crockpot Apple Dump Cake

5 from 8 votes
A crockpot cake is a low-fuss and easy-clean-up recipe that you will want to make all fall when apples are in season. You only need a handful of ingredients to make it!
Prep Time 10 minutes
4 hours
Total Time 4 hours 10 minutes
Yield 10 servings
Serving Size 1 serving


  • 5-7 Granny Smith Apples
  • 1/4 cup granulated sugar
  • 1 1/2 teaspoons cinnamon divided
  • 1 approx 15 ounce box yellow cake mix
  • 1/2 cup quick cooking oats
  • 1 stick 1/2 cup butter, sliced


  • Peel, core, and slice your apples. I used 7 because mine were small. If you’re using large, you can use less. Apples should be thin and bite sized.
  • Spray crockpot with cooking spray.
  • Place apples in the bottom of your crockpot. Sprinkle with sugar and 1/2 teaspoon of cinnamon.
  • Place the cake mix in a large bowl. Add the oats and 1 teaspoon cinnamon. Stir, then sprinkle over the top of the apples. Drop slices of the butter over the top of the cake mix.
  • Cover the crockpot with a paper towel then place the lid on. Cook on high for 4 hours. I recommend checking the cake after an hour and a half and then again each 30 minutes to make sure it's cooking evenly and doesn't burn. All crockpots cook differently so this is important. If it's too hot on one side, roate the liner.
  • Serve with ice cream or whipped cream.

Recipe Notes

This is a sweet recipe – it’s sweet from the cake mix and from the apples. Because I used granny smith, I added some sugar to the apples, but if your sweet meter is lower than mine, you can omit the sugar.
You do not need to make a batter with the cake mix. You sprinkle it over the top like a crumble, then top with butter. The butter will melt, the juices from the apples will bubble up, and the cake mix will cook.

    1. I don’t see why not! I’ve used canned peaches and pie fillings in dump cake before, so I think canned apples would be fine!

  1. I started making this and then realized I didn’t have a yellow cake mix on hand (which I usually try to always keep on hand) so I used a spice cake mix instead leaving out the extra cinnamon as the spice mix already has cinnamon in it. It actually turned out good and I would definitely do it again.

  2. I am making the crockpot Apple Dump cake now. I followed your recipe and used quick oats. I am doing it in my older smaller crockpot. Will post after we have it. My hubby is so excited. He said You are making a cake in the crockpot ??? He thinks it is so funny… I do hope it is wonderful or I am going to have some explaining to do hahaha

    1. I hope it turned out good!! I think quick oats would be fine. And I have a cake recipe too…I just love baking in the crock pot!

  3. Just put all the ingredients for the apple dump cake in my crock pot. I’ll let you know how it came out. Thank you for sharing the recipe!

  4. Best apple dessert ever!!!! Hands down!! I made this last week and it was a hit at home and at work. I cooked mine for 2 hours because my crockpot must have superheating powers. I tried the peanut butter rolo crockpot recipe before the apple dump cake, and I left it in the crockpot too long and it burned.   #lessonlearned

  5. Made this with 6 granny smith apples and used Amanda’s yellow cake mix recipe as well and let me just say heavenly aroma and heavenly flavor—The only thing I will do differently next time is use quick instead of old-fashioned oats since some oats got a little dry and tough in there and messed with the blissful “mouth-feel”…was done on high setting at 3 hours just perfectly! Thanks! My 6 qt. “crock” is red and has 2 clips on top and a steam hole vent and a dial that says off, low, high, warm….Just FYI….;0)

  6. made this yesterday with six golden delicious apples and a little bit of stevia. I used half spice cake mix and half yellow. it was delicious. I served with ice cream. Next time will sprinkle some pecans on top. 

  7. I made this this morning for a work potluck! I used red delicious so I omitted the sugar. I also used cinnamon to sprinkle over the apples, but used Apple Pie spice in the oats/cake mix. It’s nearly finished now and looks and smells WONDERFUL. I bought fat free whipped topping as well.
    thanks for a fantastic recipe.

  8. Thanks for the recipe! Based on the comments, I modified this a bit when I tried it. See, there’s two types of slow cookers. Modern ones have heating elements all around and heat dishes thoroughly. I have a small older one that I wanted to use. It only heats on the bottom. This type cautions you to cover your items in liquid or it won’t heat because it works by heating the liquid to cook the food. I think the reviewer who had the bad experience also has this type of crock pot. 

    I used 7 pretty large apples. They were a blend of Jonathan, Golden Delicious and Granny Smith, all pretty tart and firm cooking blends, that I picked myself. I peeled and chunked them. My slow cooker was probably 3/4 full of apples. Then I omitted the sugar and quadrupled the cinnamon. I did empty one Splenda packet over the apples but that’s it as far as sweetener. I added a small bit of ground nutmeg, cloves and allspice to both the apples and the cake mix. I added 1/4 cup of water to the apples before sprinkling on the cake mix. 

    I used a Moist Deluxe Yellow cake mix but added spices to it and also Old Fashioned oats. After sprinkling it over the apples, I used extra butter on top so that the entire cake mix was covered with butter pretty generously. I used salted butter. I cooked it on low for about 5 hours.

    It turned out soft and gooey and mushy and DELICIOUS. My only complaint is that the oats came out chewy and distracting. Next time, I’ll try using a spice cake mix (they didn’t have it at my market today) and chopped pecans or walnuts instead of oats but otherwise, I’m very happy. I didn’t spray the crock pot because I forgot. It didn’t turn out hard or crunchy on the edges at all. It has the consistency of a warm fall pudding, like a persimmon pudding or bread pudding, kinda. Served with vanilla ice cream, I’d totally make this for company. I like the idea of making the dessert before dinner, scenting my house with something BETTER than potpourri, and then having a hot delicious dessert that feeds several with zero effort, ready after dinner!

    Thanks for the great recipe and a way to use up some apples. I hope my tips help some that struggle. 

    1. Thank you so much for the tips! You’re right – my crockpot is definitely one of the newer kinds. We never used one growing up – so I’m new crock pot using. Didn’t know about the old kinds!!
