In a mason jar or serving bowl, whisk together the milk, Greek yogurt, vanilla, and maple syrup until well combined.
Stir in the cacao nibs, chia seeds, oats, and a pinch of salt.
Cover and place in refrigerater overnight, or for up to 5 days.
When ready to eat, top with your choice of berries and extra cacao nibs if you like. Make sure to give a good stir before enjoying.
Notes
Although these oats are safe to keep in the fridge for up to 5 days, they do continue to soften the longer they sit. For this reason, I feel they are best enjoyed on the first or second day, but feel free to experiment.
You can use quick oats if you want, though they have a tendency to get mushy pretty quickly. But maybe that's something you want, in which case, go ahead!
