In a mixing bowl, combine rolled oats, chia seeds, ground cinnamon, ginger, cardamom, cloves, nutmeg, and salt.
Whisk the dry ingredients until the spice blend is evenly distributed.
Incorporate the almond milk, Greek yogurt, vanilla extract, and maple syrup.
Stir vigorously until the mixture is homogenous and the yogurt is fully integrated.
Divide the mixture into two airtight glass containers or mason jars.
Seal the containers and refrigerate for at least 6 to 8 hours to allow the oats to fully hydrate.
Stir before serving; if the consistency is too dense, thin with a small amount of additional milk.
