Ingredients

1 (15.25-ounce) box butter pecan cake mix
1 (21-ounce) can apple pie filling
½ cup (1 stick) unsalted butter, melted
½ cup chopped pecans (optional, for extra crunch)

Directions

1. Prepare the slow cooker. Lightly grease the inside of your slow cooker with butter or cooking spray to prevent sticking.

2. Layer the apple filling. Spread the apple pie filling evenly across the bottom of the slow cooker.

3. Add the cake mix. Sprinkle the dry butter pecan cake mix evenly over the apple pie filling. Do not stir—just let it sit on top.

4. Drizzle with butter. Pour the melted butter evenly over the dry cake mix. Again, do not stir.

5. Add pecans. If using, sprinkle the chopped pecans over the top.

6. Cook. Cover the slow cooker with the lid and cook on HIGH for 2 to 3 hours, until the cake is set and the edges are golden brown and bubbling.

7. Rest and serve. Turn off the slow cooker and let the cake sit, covered, for about 15 minutes. This allows it to set and makes it easier to serve. Scoop into bowls and serve warm, with ice cream or whipped cream if desired.

Variations

Different fruit: Try cherry, peach, or blueberry pie filling instead of apple.
Different cake mix: Use spice cake, yellow cake, or caramel cake mix.
Add spices: Stir 1 teaspoon cinnamon or nutmeg into the dry cake mix.
Extra crunch: Add ½ cup shredded coconut or rolled oats.
Caramel drizzle: Drizzle caramel sauce over the top before serving.
Chocolate twist: Use chocolate cake mix and cherry pie filling for a Black Forest version.
Bourbon flavor: Add 2 tablespoons bourbon to the melted butter.

Expert Tips

Don’t stir! This is the most important step. Let the layers stay separate—they’ll combine as the cake bakes.
Grease the slow cooker well. This prevents sticking and makes serving much easier.
Check for doneness. The cake is ready when a toothpick inserted in the center comes out clean and the edges are bubbling.
Don’t peek! Try not to open the lid during the first 2 hours—the heat needs to build up.
Serve warm. This cake is best enjoyed warm, fresh from the slow cooker.
Store leftovers properly. Keep in the refrigerator and reheat in the microwave for best results.

Storage and Reheating

Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days.

Reheating: Reheat in the microwave in 30-second increments or in the slow cooker on LOW for 30 minutes.

Freezing: This cake freezes well for up to 3 months. Thaw overnight in the refrigerator before reheating.
