Add the cold brewed coffee to a large
blender. Next, add the vanilla essence (extract),
crushed ice and condensed milk. Blend well until a smooth texture is
obtained. Pour into tall, clear glasses and stir in
sugar to taste. Decorate with some whipped cream and
banana slices, if you wish.
Variations : There are countless
variations on the classic frappe. Any of the following essences would be
