Add the oats, yoghurt, milk, chia seeds, honey, cinnamon, carrots, coconut, walnuts and raisins to a jar.
Shake jar or mix and combine with a spoon. (If you like your oatmeal more creamier, you can add more milk and less if you like them on the chunkier side – you can also add an extra 2 tablespoons yogurt (dairy free if needed) to make them creamier).
Seal and chill in fridge for at least 4 hours or overnight.
Enjoy cold or heat up in the microwave or stove-top.
Serve with a sprinkle of coconut, pecans and raisins.
