I love that you called it "Home made Cool Whip"! There are people who have never had real home made whipped cream, and know none other than Cool Whip. They also do not know what they are missing.
Next time you whip the cream, try adding unsweetened cocoa powder with the confectioners sugar, for a chocolate version. Also, chill the bowl and the beaters in the freezer before you whip, it goes faster and makes a sturdier whipped cream, and if you are using a mixer, do it on high speed, (watch out for splashing).
Did you cook a fresh pumpkin for the pie? If not, next time try a baked fresh cooking-pumpkin (not the jack-o-latern type) for a much lighter pie, and you only need 2 cups of mashed pumpkin for a pie.
Doing your own baking is a great way to eat healthier and avoid processed junk foods. The only thing I think one can not make at home is Malted Milk Balls, the candy.
