I have never liked using Cool Whip in a recipe, it never does what I want it to do. Next time I will use whipped cream and just forget the Cool Whip. But, the pie tastes great. I am just glad I didn't make it for company. It didn't even turn out looking like a pie. LOL.
Oh no! You did use the instant Jello pudding mix, right? No heat involved? I can’t imagine why the cool whip would melt. I’ve never had that happen. Next time try cooling the pie before putting the cool whip on it. I’ve used cool whip a gazillion times and never has it liquified. LOL, you sound like me. I have the hardest time following a recipe. I always announce my “qualifier”. “I con’t cook.” That way if it fails, my face is saved, and if it turns out I look like a genius. All of my successful attempts have been very easy recipes that look and taste great. One I have used a lot is the angelfood cake split and layered with cherry pie filling and iced with cool whip. It looks wonderful and tastes great, and company goes ooooo and ahhhhh and I pat a little flour on my face and say, “It was nothing, really.”
