Preheat your oven to 375 degrees. Line a baking sheet with parchment paper, set aside. Lie down a sheet of parchment paper on the counter. Roll out each of the 8 crescent rolls individually.
In a small bowl, whisk together brown sugar, cinnamon, and nutmeg. Add 2 tbsp of the cinnamon-sugar mixture to each crescent and layer it evenly.
Divide the chopped pecans evenly between the crescents.
Take the apple slices and toss them in the melted butter. Add one apple slice to the wide end of your crescent roll, and roll it up towards the narrow end. Repeat for the remaining rolls.
Brush the tops of the rolls with melted butter and place onto your parchment covered cookie sheet. Bake 9-10 minutes until crescents begin to turn golden brown.
Drizzle with homemade caramel sauce, and serve with vanilla ice cream.
For the Sauce
In a small saucepan, bring brown sugar, butter, and milk to a boil. Cook for 1-2 minutes, stirring constantly, until the caramel thickens. Remove from heat and stir in vanilla.
