In a medium mixing bowl, combine 1 cup of old-fashioned oats, 2 tablespoons of chia seeds, 1 cup of your preferred milk, and ½ cup of plain Greek yogurt. Add 1 teaspoon of vanilla extract for flavor. Stir the mixture thoroughly using a whisk or spoon until everything is well incorporated and no dry oats remain visible.

Continue stirring for about 1 minute to achieve a creamy, smooth texture. Pay attention to ensure that the chia seeds and oatmeal are evenly distributed throughout the mixture.

Once your mixture is well combined, divide it equally into 2 mason jars or airtight containers. Aim for about ¾ of the way full to leave room for any toppings you wish to add later.

Place the jars in the refrigerator and allow them to chill for at least 4-5 hours, or ideally overnight.

When you're ready to enjoy your high-protein overnight oats, remove the jars from the refrigerator and stir gently to combine any settled ingredients. Top with your favorite fruits and a drizzle of nut butter.

Feel free to explore different toppings for each jar, like granola for crunch or honey for sweetness.
