I tried to create a frappuccino using cold coffee, milk & ice cubes. But when i blended it all together, the coffee was too weak and diluted by all the ice. What about coffee ice cubes? Would be a great way to use up left over coffee... So i blended a cup of milk with 7-10 coffee ice cubes, and 1-2 tbs sugar (or however sweet you like it!) And Voila, a non-diluted homemade frappuccino!
