This is an old family recipe that my mother in law used to make, then I started making if for my kids, they absolutely love it. If you are not a fan of frozen whipped topping I have found that you can substitute it for whipped real whipping cream 1:1. It does affect the texture a bit. I often will do a 50:50 ratio of real whipped cream and frozen whipped topping. It works perfectly as well.
