Combine Ingredients: In a jar or airtight container, add the rolled oats, milk, yogurt (if using), chia seeds, honey or maple syrup (if desired), vanilla extract, and a pinch of salt. Stir or shake well to combine all the ingredients.
Mix Thoroughly: Make sure all the oats are submerged in the liquid and that the chia seeds are evenly distributed. This helps prevent clumping and ensures everything is well-mixed.
Refrigerate: Seal the jar or container and place it in the refrigerator for at least 6 hours, or preferably overnight. This allows the oats to absorb the liquid and soften, while the chia seeds swell, creating a thick, pudding-like consistency.
Add Toppings: In the morning, give the oats a good stir. If the mixture is too thick for your liking, you can add a splash of milk to loosen it up. Top your overnight oats with your favorite fruits, nuts, seeds, or any other toppings you enjoy.
Serve and Enjoy: Your overnight oats are ready to eat! You can enjoy them cold, or heat them up in the microwave for about 30-60 seconds if you prefer them warm.
