Mix the butter, sugar and bournvita powder and make it into a fine creamy texture.
Add the coffee powder to the milk. Dip each biscuit in this mixture and apply the
cream in between each biscuit but only a very thin layer[this is optional] and
arrange it in a stack neatly one on top of the other.
Now apply a thick layer on all sides of the stack evenly.
Refrigerate for 2 hours, remove and cut into slices.
