Make pumpkin puree. (Watch the video below)
Combine all ingredients in a large bowl and stir well until everything is evenly incorporated. This mixture will thicken as it sits, so it should be a little runny first.
Place the mixture in a glass jar(s), and put in the fridge until the next morning.
In the morning put a few spoon of oats mixture in a bowl, add your favorite toppings and enjoy!
Store overnight oats in a closed glass jar in the fridge for up to 7 days.
