In a large mixing bowl, stir together the sweetened condensed milk, and strawberry flavored Kool-Aid powder until all the Kool-Aid powder has been dissolved into the sweetened condensed milk and you have a bright pink mixture.
Gently fold the entire container of thawed extra creamy Cool Whip whipped topping into the sweetened condensed milk mixture until no white streaks remain from the whipped topping. You should have a beautiful light pink Kool-Aid pie filling.
Remove the plastic insert from the premade graham cracker crust (save that plastic piece) and fill the crust with the Kool-Aid filling. Smooth the top and invert the plastic piece to use as a lid for your pie.
Chill your strawberry Kool-Aid pie for 4 to 6 hours or up to overnight.
Notes
If you have strawberries hanging out in your fridge, you could mix a few diced strawberries into your Kool-Aid and Cool Whip mixture.
You can use the plastic cover on the graham cracker crust as the lid for this tasty pie. Remove the paper center on the lid.
This no-bake pie does take a while to set, so ensure that you give yourself a good 4 to 6 hours before you want to enjoy it.
You can garnish the top of the pie with fresh strawberries if desired before slicing and serving.
