I've tried making the cream cheese filling with homemade whipped cream; for some reason, it just hasn't worked as well. So I usually reserve my whipped topping for the top and use Dream Whip for the filling, which is what my mom uses in her cherry crunch. Now some people do make this filling with Cool Whip, but I’ve carried on my mom’s tradition of a creamy Dream Whip filling. I like to call it angel fluff.
