In a blender, combine 1 cup of unsweetened almond milk, 1 cup of diced fresh mango, and 1 teaspoon of vanilla extract. Blend on high until smooth and creamy, about 30 seconds.

Gather four small jars or containers and add ½ cup of rolled oats, ½ cup of Greek yogurt, 1 tablespoon of chia seeds, and ½ teaspoon of ground cinnamon to each.

Pour the smooth mango mixture over the dry ingredients in each jar. Stir well until all components are combined evenly.

Cover the jars tightly and place them in the refrigerator. Allow chilling for at least 2 hours, or overnight for best results.

Once chilled, remove the jars from the refrigerator. Add optional toppings like additional diced mango, coconut flakes, or a sprinkle of cinnamon before serving.
