Apple Dump Cake Ingredients 1 cup water 21 ounce can apple pie filling 1 1/2 cups yellow cake mix 4 tablespoons butter, melted Instructions 1 Begin this recipe by grabbing your instant pot/pressure cooker and place the trivet into the bottom. Add in one cup of water. 2 Next use a dish or pan that will fit inside the instant pot. Pour the whole 20 ounce can of apple pie filling into the bottom of the dish and spread evenly. 3 Top with 1 ½ cups of the yellow cake mix and gently press it down evenly into the dish on top of the apple pie filling. Do not use the entire bag of cake mix. 4 Top with four tablespoons of melted butter and spread evenly on top of the cake mix. 5 Place the dish into the instant pot and cover with the lid. Make sure it is set to sealing and not venting. Set the cooking time on manual for 25 minutes. 6 Use quick release by switching the knob to venting. Once the pressure has released immediately remove the lid and carefully remove the apple dump cake. Store any leftovers in an airtight container in the refrigerator up to 3 days. Notes Tips to make the best apple dump cake recipe: Do not mix the butter into the cake mix, just lightly spread it on top as evenly as you can. It does not have to be perfect. You may substitute the yellow cake mix for another mix. Try butter golden or spice cake! Use the trivet in the bottom of the instant pot to lift the dish out of the water. Once the cooking time is up, use quick release and remove from the instant pot so water does not drip from the instant pot top into the apple dump cake. Do not use the entire bag of cake mix.
