In a mason jar, combine the rolled oats, mango chunks, almond milk, vegan yogurt (if using), chia seeds, maple syrup, vanilla extract, and a pinch of salt. Stir well to ensure everything is mixed evenly.
Cover the jar with a lid or plastic wrap, and refrigerate overnight (or for at least 4 hours) to allow the oats to soak up the liquid and soften.
In the morning, give the oats a good stir. If the mixture is too thick, add a splash of almond milk to reach your desired consistency. Top with extra diced mango and other toppings you like (such as nuts, seeds, or coconut flakes).
Notes
Prep in Jars: Mason jars are perfect for portion control and easy grab-and-go breakfasts.
Blend the Mangoes: Blend some mangoes with almond milk before mixing in the other ingredients for an extra burst of mango flavor in every spoonful.
Additional Toppings: Top your mango overnight oats with nuts, seeds, fresh fruit, or granola for crunch. Add coconut flakes, nut butter, or spices for extra flavor.
