Yesterday, I had left some Cool Whip out to thaw for a WAM session, but my partner had to reschedule. I noticed it dried out considerably as I had left it out for more than a few hours (lost its 'creaminess'). Anyways, we rescheduled for today and I put it back in the freezer in hopes to preserve it.

The texture overall is dry but I *think* will be okay for a session. I don't really want to buy more cool whip if I don't have to, but I'm not sure how using dried out cool whip will play out. Does anyone have experience with this?

Add a little water, or oil.

I'd say add a tiny bit of oil. Cool Whip is oil-based so that should help out.
