Preheat oven to 350 degrees and grease an 8x8 baking dish.
Make the filling by combining the oats, pecans, brown sugar, flour, cinnamon, and salt in a mixing bowl. Add the melted butter and stir to combine. Set aside to cool before adding chocolate chips.
Core and remove the insides of each apple with a spoon or melon baller, being careful not to damage the bottom and sides of the apples (or they won’t hold the filling). Set aside.
Once the filling is cooled to room temperature, stir in the mini chocolate chips.
Fill each apple with the filling and place them in the baking dish. Bake in the preheated oven for 30-35 minutes, or until the apples are softened and the tops are golden brown.
Remove from oven and drizzle with caramel sauce if desired
Notes
These keep well in the fridge for up to 2 days, just reheat in the microwave in 30 second increments. I do not recommend freezing them.
Don’t add the chocolate chips until the filling has cooled, otherwise they’ll melt!
