01 - Whisk together the milk and matcha powder in a medium bowl or jar until smooth and fully dissolved, ensuring no lumps remain.
02 - Add rolled oats, chia seeds, and honey or maple syrup to the matcha milk. Stir thoroughly until all ingredients are evenly incorporated.
03 - Cover the mixture and refrigerate for at least 6 hours, preferably overnight, allowing oats to absorb liquid and achieve creamy texture.
04 - Stir the oats in the morning. Add a splash of milk if thinner consistency is preferred.
05 - Divide between serving bowls or jars. Top with sliced banana, toasted coconut flakes, chopped nuts, and fresh berries as desired.
