In a mixing bowl, combine the rolled oats, almond milk, canned pumpkin puree, and Greek yogurt. Stir until well mixed.
Add the maple syrup, ground cinnamon, nutmeg, ginger, and vanilla extract to the mixture. Stir until all ingredients are well incorporated.
Divide the mixture evenly into two jars or containers with lids.
Seal the jars and place them in the refrigerator overnight (or for at least 4 hours) to allow the oats to soak and soften.
In the morning, remove the jars from the refrigerator and give the oats a good stir. If you prefer a thinner consistency, you can add a splash of almond milk.
Top the oats with your choice of chopped pecans, a dollop of whipped cream, or a sprinkle of pumpkin seeds for added texture and flavor.
Notes
Serve in clear jars to showcase the layers and add a sprinkle of cinnamon on top for extra flavor.
