In a large mixing bowl, combine rolled oats, almond milk, vanilla extract, ground cinnamon, and maple syrup. Stir vigorously for about 1-2 minutes until all ingredients are well blended.

Gently fold in diced peaches and Greek yogurt, ensuring not to mash the fruit.

Spoon the mixture evenly into four airtight jars, leaving some space at the top.

Seal each jar tightly and refrigerate them for at least 4 hours, preferably overnight.

When ready to eat, stir the oats, and enjoy cold or warm in the microwave for 30-60 seconds.
