Simple preparation, and gets easier every time you do it.
First instructable, so please bare with me.
Step 1: Gather Your Ingredients
All measurements are rough and specifically made for the cups I use to mix, so you can make this up in a different container if you do not have cups as large as the ones shown.
You can vary for your preferred taste as well.
3 cups of room temp coffee (it can be coffee from yesterday, if you really dont wanna waste it)
2 Tablespoons of Vanilla Extract
1/8 - 1/4 cup of sugar
1/4 cup of The powdered "original" creamer
Some ice cubes
You'll also need mixing cups (2), and stuff to measure the ingredients with.
Cocktail Strainer (Helps with removing the ice, that's all)
Wire/Mesh Strainer (Gets rid of unmixed clumps of creamer, you'll see what I'm talking about)
Step 2: Prepare to Mix
In the other cup, pour in the coffee.
Step 3: Mix It Up
Pour the coffee into the other ingredients first.
After they are together, simply pour it back and forth about a dozen times for a decent mixture.
Step 4: Strain It
Step 5: Chill It
Pour back and forth between the cups a few more times (about 6 for a quickly chilled drink)
Use the cocktail strainer to get rid of the cubes if you'd like
Step 6: Enjoy
Really REALLY easy to make in a minute or two once you do it a few times.
Other things you could try are alternative flavors, no word yet on how my tests of different things are, but if I find something tasty, I'll add another step in here for flavors.
I know it is a bit of a lengthy instructable for something so simple, but hey, it's my first, and I didn't want to miss anything.
