Preheat oven to 425F and set aside a greased 9x13 baking dish.
Stir together apples, lemon juice, coconut sugar, cinnamon, nutmeg, and ginger in a large mixing bowl.
Place a large saucepan over medium heat.
Add coconut oil and apple mixture to the saucepan and cook, stirring occasionally, for 8-10 minutes, or until apples slightly soften and caramelize.
Spoon cooked apples into the baking dish. Let cool while you make the biscuits.
Combine almond flour, oat flour, baking powder, baking soda, and salt in a large mixing bowl.
Cut butter into the flour mixture using a pastry cutter (you can also use a grater to create small pieces of butter). You will want pea-sized pieces of butter throughout flour mixture.
In a separate bowl, whisk together egg, yogurt, and maple syrup until smooth.
Pour wet ingredients into the bowl of dry ingredients and stir to combine.
Use a large ice cream scoop to drop about 1/3 cup of biscuit batter on top of cooked apples, creating 12 biscuits total.
Brush the tops of each biscuit with melted butter (or butter replacement).
Bake in the oven for 16-18 minutes, or until tops of biscuits are golden brown. Let cool about 15 minutes then serve (vanilla ice cream makes a great topping).
