1) If you have leftover coffee from the morning(as i usually do), SAVE IT, keep it in the fridge to chill.
2) Put about a spoonful of sugar in the bottom of the cup.
3) Add about less then half cold coffee in glass.
4) Top with milk, stir.
NOTE---> No need for ICE, as using BOTH coffee and milk already chilled will keep it perfectly chilled, however if your coffee is warm, add ice. ENJOY!
