Preheat oven to 350°F.
Combine oats, pecans, cinnamon, ginger, allspice, and maple syrup in a bowl and mix thoroughly.
Remove the apple cores without cutting through the bottom of the apples. Scoop out some flesh to make room for the filling.
Fill the apples with the mixture.
Place apples in a baking dish and add a layer of water to the bottom of the dish.
Bake for 30-40 minutes (depending on the size of the apples). You want them to be tender, but not mushy. If a knife easily slides through, they are done and you can remove them from the oven.
Top each apple with one scoop of Halo Top Sea Salt Caramel.
