01 - In a medium bowl or mason jar, combine the rolled oats, milk, Greek yogurt, protein powder, chia seeds, honey or maple syrup, vanilla extract, and a pinch of salt. Stir thoroughly until all ingredients are evenly incorporated and no dry pockets remain.
02 - Cover the bowl tightly with plastic wrap or seal the mason jar with its lid. Place in the refrigerator and let it chill for at least 6 hours or overnight to allow the oats to absorb the liquid and soften.
03 - The following morning, remove from the refrigerator and give the oats a good stir. Add a splash of milk if a thinner, creamier consistency is desired.
04 - Top with fresh berries, sliced banana, chopped nuts, nut butter, or shredded coconut. Serve cold directly from the refrigerator.
