Melt one tablespoon of butter in a skillet over medium-high heat. Add the pecans and toast for 2-3 minutes or until lightly toasted and fragrant. Set aside.
Add the apple pie filling to the bottom of the crockpot and spread out across the bottom. Sprinkle with the toasted pecans, reserving 1-2 tablespoons for topping the cake if desired.
Pour 1/2 cup of caramel sauce evenly over the top.
Sprinkle dry cake mix evenly over the entire mixture. Place thin butter slices on the top of the cake mix.
Place 3 paper towels under the lid and set the crockpot to high heat for 2-3 hours or cook on low for 4-6 hours, or until the cake mix is cooked and filling is bubbly. Check for doneness after 2 hours of cooking on high, and 4 hours of cooking on low.
Serve warm with vanilla ice cream or whipped cream and drizzle with extra caramel sauce and reserved toasted pecans.
Notes
Be sure to grease the crockpot to prevent the cake from sticking to the sides of the crockpot. Using paper towels or a kitchen towel under the lid will help keep condensation from running down onto the cake, thus preventing a soggy cake. Feel free to use a gluten-free cake mix. Change up the type of nuts or cake or filling to create your favorite flavor of dump cake. If using fresh apples, you may have to cook it longer. Oven Instructions: You can make it in a 9 x 13-inch baking dish and bake in the oven at 350° for 45-60 minutes. Store leftovers in an airtight container and refrigerate for up to 5 days. To reheat, microwave for 20- 30 seconds or until warm, and top with ice cream.
