Combine carrots, oats, raisins, walnuts, chia seeds and flaxseed meal in a medium-sized mixing bowl with fitting lid.
In a separate container, combine remaining ingredients and mix well with a fork or whisk until well combined. Pour over oat mixture and mix with a spoon until well combined.
Cover and refrigerate for at least 4 hours (preferably overnight) before serving.
When ready to eat, add a little bit more milk, if desired, and garnish with a pinch of grated carrots, a few more raisins and chopped nuts.
