- Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish. 
- In a saucepan over medium heat, melt the butter and sugar together until the mixture turns golden brown. Slowly whisk in the cream and vanilla, then remove from heat. Let it cool slightly. 
- In a large bowl, whisk the eggs. Add the flour, baking powder, salt, and milk, stirring until smooth. 
- Fold in the chopped apples. Pour the batter into the prepared dish. 
- Sprinkle the dry cake mix evenly over the top. Drizzle half of the caramel sauce over the cake mix. 
- Top with chopped pecans if using. 
- Bake for 35–40 minutes or until golden and bubbling. Let cool slightly before serving. Drizzle with the remaining caramel sauce.
