If you want to get adventurous with flavors Amazon has a pack of 22 different Kool-Aid Drink Mix Flavors. You can easily make this no-bake Kool Aid Pie the day before you need to serve it.

One of the best things about cooking/baking with Kool Aid is you can easily change the flavors by grabbing a new drink mix. You can use pretty much any flavor of Kool-Aid to make these slushies.
