Combine Ingredients: In a mason jar or other container, mix rolled oats, milk, and yogurt. Stir well to ensure even distribution.
Add Sweetener: If desired, add a sweetener of your choice, such as honey or maple syrup. (Skip the brown sugar as natural sweeteners will do the trick just fine.) Adjust the sweetness to suit your taste preferences.
Mix and Seal: Stir the mixture thoroughly, ensuring oats are fully coated. Seal the jar or container with a lid.
Refrigerate Overnight: Place the sealed jar or container in the refrigerator and let it soak overnight. This allows the oats to absorb the liquid and soften.
Top Before Serving: In the morning, give the oats a good stir. Add your favorite toppings such as fresh fruits, nuts, dark chocolate chips or seeds.
Enjoy: Your overnight oats are ready to eat! You can eat them cold or warm them up in the microwave if you prefer a warm breakfast.
