Author Dorothy Kern


  • 5-7 Granny Smith Apples
  • 1/4 cup granulated sugar
  • 1 1/2 teaspoons cinnamon divided
  • 1 box yellow cake mix
  • 1/2 cup oats quick cook or old-fashioned
  • 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 and cook on high for 4 hours. (My crockpot defaults to HIGH power for 4 hours. As you can see, it got a little dark around the edges, so if you have a "low" setting, you can try that instead.) All crockpots cook differently. Yours might take less time. Start checking at 1 1/2 hours. Once all the butter is melted and the powder is gone and the top is golden, it is done. I sometimes start with a paper towel between the lid and insert, but with this cake I like to remove it after about 2 hours so the condensation helps to dissolve the cake mix. Once you bake in your crockpot awhile you'll learn how it bakes (faster/shorter, hotter etc.) Serve with ice cream or whipped cream.
