I love the idea of this. We don't have kool aid here in Australia but I was given some in a swap so tried this with the cherry flavour, I wish I had of used a different flavour as it tasted a bit too much like medicine to me, not the recipe's fault though. I ended up adding some fruit juice to the mic to kill the cherry taste. I would make this again when I have leftover condensed milk but with a different flavour next time.
I made this today for Isaiah, my 4 yr old, using cherry flavored koolaid and squeezable sweetened condensed milk so I wouldnt have to waste a can of it! Very creamy and not too fruity. Might use 2 packages of koolaid next time! He loved it though. Thanks for an easy drink!
