Place the oats, oat milk, chia seeds, cookie butter and sweetener in a jar with a secure lid.
Tighten the lid and shake it up until combined.
Place in the fridge overnight or at least 2 hours.
When you’re ready to eat, give the oats a good stir and enjoy!
Tips
When your cookie butter jar is empty, don’t rinse it out! Just add all the recipe ingredients to the jar, pop that lid back on and place it in the fridge. A little extra cookie butter from the jar makes the most sweet and delicious oats!
