In a bowl, mix the chopped apple, cinnamon, and arrowroot starch.
In another bowl, mix together the oats, almond flour, maple syrup, and almond milk.
In two microwave-safe dishes, split the seasoned apples equally and divide the topping mixture over each.
Microwave for 3 minutes or until the apples are soft and the topping forms a crust.
Optional: Drizzle with a little extra maple syrup and enjoy!
