Place all the ingredients (except for the chocolate chips) in a blender and mix until smooth. Alternatively this can be done with a hand blender. (If you have neither of these you can use a hand whisk and whisk the ingredients. The resultant pudding will not be as smooth but will still taste delicious).
Evenly divide between 4 bowls/glasses/ramekins and place in the fridge for a minimum of 4 hrs (overnight is ok).
Garnish with Chocolate Chips, berries or cream (all optional) and serve.
