Cool Whip instead of whipping cream whipped

I presume you meant "mixed with jello". The "J" and "H" keys are right next to each other after all.

I don't know the answer to your question though. However, I think there are others here who are more into food and cooking than I am. Hopefully they can help you.

I'm mainly bumping this topic. Cool Whip is lighter so the proportions may differ - and the results might as well.
