In a jar or container with a lid, combine the rolled oats and almond milk.
Add the peach slices, mango chunks, maple syrup or honey, and vanilla extract.
Stir well to combine all the ingredients.
Cover the jar or container and refrigerate overnight, or for at least 8 hours.
In the morning, give the oats a good stir and top with additional peach slices, mango chunks, and shredded coconut if desired.
Enjoy your Peach Mango & Vanilla Overnight Oats!
