In a large mixing bowl or mason jar, combine the old-fashioned oats, unflavored protein powder, protein plant milk, nonfat plain Greek yogurt, sugar-free syrup, vanilla extract, and a dash of cinnamon. Stir well until all ingredients are fully incorporated and creamy.

Cover your bowl or jar tightly and refrigerate for at least 8 hours or overnight to allow the oats to absorb the liquid.

The next morning, stir the oats and layer them with a generous handful of crushed Cinnamon Squares cereal.
