Preheat your oven to 375F. Add the oats, chopped pecans, dried fruit, coconut sugar, cinnamon nutmeg, and melted butter to a bowl. Then mix that together until it's well combined.
Using a melon baller or paring knife, core the tops of the apples. Then scoop out some of the apple, so that you have a cavity about an inch and a half wide. Just make sure you don't core through the bottom of the apple.
Remove about 1/2" of the skin around the top. This helps to prevent the apple skin from bursting when baking. Transfer your apples to a baking dish, standing them upright, and if they wobble you can slice a little bit off the bottom to make them more stable. Then squeeze the lemon over the top edge of the apple.
Then stuff the apples with the cinnamon oat mixture.
Pour the apple cider or apple juice into the bottom of the pan.
Bake the apples for 45-60 minutes, basting a couple of times throughout with the liquid from the pan. The apples are done when they're tender when pierced with a fork.
Spoon the syrupy liquid from the pan over the apples before serving. You can also top them with a scoop of ice cream, whipped cream, caramel sauce, or a dash of cinnamon.
