Combine Ingredients: Begin by adding the rolled oats, chia seeds, yogurt, milk, vanilla extract, salt, matcha powder, and maple syrup into a mixing bowl. Stir until everything is evenly incorporated for a smooth consistency.
Refrigerate Mixture: Once combined, cover the bowl tightly or transfer the mixture into individual containers for portion control. Place it in the refrigerator to chill for at least four hours, though overnight soaking yields the best results.
Serve and Enjoy: When you're ready to enjoy your Matcha Overnight Oats, remove them from the fridge and give them a gentle stir. Top with chopped fruits or berries to enhance flavor and presentation before digging in!
