In a medium bowl, combine rolled oats, chia seeds, matcha powder, cinnamon, and a pinch of salt. Stir until evenly mixed.

In a separate container, whisk together plain Greek yogurt, unsweetened milk, vanilla extract, and maple syrup until smooth.

Pour the wet ingredient mixture into the dry ingredients bowl. Gently fold the components together.

Spoon the combined mixture into individual jars, filling them to about three-quarters full.

Top your jars with fresh fruit, a drizzle of nut butter, or a sprinkle of nuts and seeds.

Cover each jar and refrigerate for at least 2 hours, ideally overnight.

When serving, remove jars from the refrigerator, stir, and add a splash of milk if needed.
