In a jar or bowl, combine the oats, milk and pumpkin and stir until combined.
Add in the maple syrup, spices, chia and flax seeds and mix again. You want to make sure that the chia and flax are fully saturated to help thicken the oats!
To bring out the sweetness, add a pinch of salt.
Refrigerate the oats for 12-24 hours and then eat! You can also only fridge these for 2-6 hours, but they won't get as thick. They'll still be delicious though :)
*Note: You can add optional ingredients either before or after refrigeration, it's really up to how you like your oats and your cravings and nutritional needs for that day! I've included some of my favorite add-ins above, and you can mix and match as you like.
