Brew your favourite coffee and let sit overnight in the fridge or allow it to cool to room temperature on the counter.
Fill your tall glass to the top with ice.
Pour over your brewed coffee, leaving 1-2 inches at the top for cream.
Pour in your favourite creamer. You can get lots of different flavors. Vanilla and hazelnut are delicious iced. Make sure you leave a bit a room for stirring in your sugar.
Add in your sugar or sweetener of choice. You could add your sugar in while coffee is hot to help it dissolve.
Stir and serve with your favourite straw.
Notes
You can add sugar to hot coffee so it can dissolve, or you can use a simple syrup as well.
