In a jar or container with a lid, combine the rolled oats, milk, apple juice, chia seeds, maple syrup, orange zest, cinnamon, cloves, and nutmeg.
Stir all the ingredients together until everything is well combined. Make sure there are no clumps of chia seeds.
Cover the jar or container and refrigerate for at least 4 hours, or preferably overnight. This allows the oats to soften and the flavors to meld together.
In the morning, give the oats a good stir. If they seem too thick, add a splash of milk to reach your desired consistency.
Top with your favorite toppings, such as chopped apples, cranberries, walnuts, or slivered almonds.
