Add all the ingredients for the apple pie overnight oats into a bowl. Stir until combined. (If you don't have pre-cooked apples, peel and chop an apple into small pieces. Add the apples to a pan with a 1/2 tbsp of butter and a dash of cinnamon. Add a splash of water and cook over low heat for 4-5 minutes until the apples are soft.)
Transfer the mixture to the fridge for at least 2 hours or overnight.
Just before serving, make the yogurt: Add the greek yogurt, cream cheese, maple syrup, and vanilla extract to a small bowl. Stir until combined and smooth.
Top the oats with the cream cheese yogurt and a little extra cinnamon (optional). Enjoy!
