This won't work unless you can put ice cubes in your blender without breaking it. You might want to test it first. I'll wait ... Did it break? No? Good. Then let's proceed

First get some good coffee. Hopefully from me.

Brew up a pot and let it cool some because you're going to make ice cubes with it and you don't want to melt your ice cube tray.

Make coffee ice cubes.

Now it's time to not break your blender. Put in 6 to 8 coffee cubes per serving into the blender.

Add a 2 to 3 ounces per serving of cream, half & half, milk, nonfat milk, pre-mixed non-dairy creamer, soy or rice milk, or whatever milk-like substance you prefer into the blender.

(Real Important) Put The Top on the Blender before you turn it on.

Turn on the blender. (Noisy isn't it?)

Blend until the mixture is almost milkshake-like.

(Real Important) Turn off the blender before you take the top off to taste.

Add whatever sugar-like substance you use to taste.

Blend a bit to more make sure the sweetener is incorporated.

Taste it again. Good isn't it?

If your blender breaks and you really like this type of iced coffee you might want to buy an ice crusher ... and another blender. Cheap blenders tolerate pre-crushed coffee cubes mo' better.

Do not make this drink at night because blender noise wakes up all the dogs within a two block radius.

Note:
Adding alcohol to this iced drink during the blending stage makes a fine refreshing summer drink that turns mowing the lawn into a challenging and possibly lethal task.
