Combine the Ingredients: In a jar or container with a lid, add the rolled oats, milk, Greek yogurt, chia seeds, honey or maple syrup, and vanilla extract. If using a probiotic capsule, open it and sprinkle the powder into the mixture.
Mix Well: Stir everything together thoroughly to ensure all the ingredients are well combined. This helps distribute the flavors and prevents the chia seeds from clumping.
Refrigerate Overnight: Cover the jar or container and place it in the refrigerator for at least 6 hours, or preferably overnight. This allows the oats to soften and absorb the liquid, creating a creamy and delicious texture.
Add Toppings and Enjoy: In the morning, give the overnight oats a good stir. If they seem too thick, add a splash of milk to reach your desired consistency. Top with your favorite fruits, nuts, seeds, or any other toppings you like.
