01 - In a large mixing bowl or jar, add rolled oats, almond milk, Greek yogurt, chia seeds, and protein powder.
02 - Add maple syrup or honey and vanilla extract to the mixture. Stir thoroughly until the ingredients are smooth and completely combined.
03 - Cover the bowl or jar securely and refrigerate for at least 8 hours, or overnight, permitting the oats and chia seeds to fully absorb the liquid.
