Combine all the dry ingredients in a medium-sized mixing bowl with fitting lid.
In a separate container, combine all the wet ingredient and mix well with a fork or whisk until well combined. Pour over dry ingredients, mix with a spoon until well combined.
Cover and refrigerate for at least 4 hours, but 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.
