hello fellow cc'rs, I just bought my first sleeve filling and am kinda leary of using it. I have heard and read that they are non-perishable, but the lady told me to mix it with cool whip??? I was thinking of just mixing it with BC... or do I just use the filling with a dam? Thanx everyone!

If you mix it with Cool Whip it becomes perishable, obviously. You can mix it in with your BC OR dam your cake with BC and fill with the sleeve filling to make it totally shelf stable.

for 14 yrs.. i have made a dam... put in my sleeve filling.. that is all i do...it does not get runny.. or make cake layer soggy. it never has with me.. don,t know what happens when other people say . . their cake layer gets soggy.. hth anyone.. that i have watched use it.. do the same thing. my teacher taught me that way .... when i took cake decorating lessons..

I just mix it with regular buttercream.

I often put a very very thin coating of buttercream over the bottom layer then put a dam. Next, fill with the sleeve filling and then put the layer on top. The thin layer of buttercream under the filling prevents the sleeve filling from soaking into the layer.
I don't know if this is really necessary but it works for me.
