Preheat the oven to 350 degrees Fahrenheit.
Slice the tops ("hats") off of each apple and do not discard. Using a melon baller or pairing knife, hollow out the center of the apple removing most of the core but leaving 1/2 an inch at the bottom, so the fillings do not fall out.
In a medium bowl, mix together the pecans/almonds, almond flour, maple syrup, coconut oil, cinnamon, allspice/cloves/nutmeg/ginger, and salt to create the filling.
Spoon the maple pecan filling into the hollowed-out core of each apple.
Place each apple into a deep baking pan. Pour the 1/4 cup of cider, apple juice, or water into the bottom of the pan. Place the hats on top of each apple.
Cover loosely with tin foil and bake for 30-40 minutes, basting every 15-20 minutes with the cider/apple juice/water liquid. Bake until the apples are cooked through.
Once apples are finished baking, remove from oven and let cool for 10 minutes. Top with desired toppings. Serve and enjoy!
