Add all of the ingredients (except the fruit) to a 2 cup mason jar and mix together well.
Add 1/2 cup of frozen berries on top.
Cover with the lid and allow to sit in the fridge overnight. The jars can be stored in the fridge for up to 5 days.
Stir the fruit into the oats before serving and enjoy!
Notes
These overnight oats are to be eaten cold, like cereal. No cooking required!If you're planning to eat your overnight oats with fresh fruit instead of frozen, add the fresh fruit in the morning, rather than storing it in the mason jar. Fresh fruit will last in the jars for 1 to 2 days.
