Add oats, milk, chia seeds, sweetener, cinnamon, carrots, coconut, pecans, and raisins to a mason jar or a bowl.
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 for 20-25 seconds at a time, stirring between each interval until warmed through.
Serve with more milk as desired and sprinkle with additional coconut, pecans and raisins before serving (optional) together in a mason jar, resealable container or a bowl.
